A scraper is a tool used to scrape or remove the surface of an object. It usually consists of a blade and a grip. The blade of a scraper can be made of materials such as metal, plastic, or rubber, with sharp edges, used to scrape away substances such as paint, glue, wax, etc. The grip of a scraper is generally in a shape that can be held by a human hand for easy operation. Scrapers are widely used in fields such as home decoration, maintenance, and beauty, and can be used to remove old paint from walls, repair furniture surfaces, and clean window glass. When using a scraper, it is necessary to pay attention to safety and avoid blade injuries or damage to objects.

When we decorate indoors, we always worry about inadequate protection during painting or brushing, causing paint to be scattered everywhere and making it difficult to clean. Choosing a high-quality Adhesive Masking Film can effectively solve various problems and be a good helper when painting. Advantages of Plastic Masking Film: 1. It has a certain tensile strength to prevent damage and fracture during use. 2. It will not penetrate colors and can draw perfect edge lines. It will not pollute other places. 3. The adhesive tape has strong adhesion, and the surfaces of various materials can be fixed. There is no residual adhesive on the surface of the object after use. 4. Multiple sizes available for customization. A Plastic Masking Film is a protective film used to cover a surface during painting, construction or other similar applications. It is usually made of a thin, flexible plastic material that is adhered to a surface with an adhesive backing. Masking films are designed to provide a temporary barrier to protect surfaces from paint, dust, debris and other potential damage. It is commonly used in automotive painting, home improvement projects and industrial applications. Masking films are available in a variety of sizes and thicknesses to suit different surfaces and project requirements.

Soft bristled car brushes are suitable for cleaning parts such as car bodies, wheels, and windows, effectively removing dirt and oil stains, making the car look brand new. When using a soft bristled car brush, it is important to avoid using excessive force to prevent the bristles from becoming too hard or impurities on the brush head from scratching the car paint. In short, a soft bristled car brush is a convenient, safe, and effective car cleaning tool that can help car owners easily clean their cars and maintain the smoothness and brightness of the body.

Painting is an important part of daily decoration. Good painting not only adds color to indoor spaces, but also protects walls. The common painting methods mainly include the following three types: using paint brush, using roller brush, and spraying. 1. Paint brushing Mainly suitable for ceiling, wall, and iron window railing surfaces. Before applying paint, we need to immerse the bristles into half the height of the paint. If you are worried that the bristles may get too much paint, you can gently scrape the edges of the paint can a few times to prevent the paint from dripping during the construction process. During the painting process, it is necessary to clamp the brush handle with your thumb and index finger, and use force from your fingertips to slightly bend the bristles, in order to achieve better brushing effect. We need to brush the unpainted part to the previously painted part. Be sure to avoid repeated brushing on previously painted but not dried surfaces. The advantages of paint brushing are easy control of brushing force, low consumption of consumables, and obvious brush marks. 2. Roller brushing paint Mainly suitable for painting walls and ceilings, although rollers save time compared to brushes, they may produce different patterns and uneven brush marks depending on the surface or roughness of the rollers. We need to choose the appropriate drum size and avoid using oily coatings to prevent difficulties during the drum coating process. Before applying paint, roll the drum into the paint tray and gently rotate it to fully apply the paint. Then move it onto the surface of the object and roll it to evenly distribute the paint. When painting, it is necessary to draw in the form of dashed lines, using M, W, or inverted N type scrolling up and down to evenly fill the blank. The advantage of roller brushing paint is that it has a tactile feel and is very suitable for DIY, but the disadvantage is that the brush marks are obvious, the paint film is thicker, and it is easier to consume paint. 3. Spray painting machine Mainly suitable for large spaces, pay attention to covering indoor furniture and debris during painting to avoid getting dirty by floating paint. During the construction process, the spray gun and the wall should be transported vertically and parallel, and the swing speed should be maintained as much as possible to avoid the problem of thin and uneven local paint. Its advantages are smooth surface of the paint film, good texture, and time-saving and labor-saving. The disadvantage is that dead corners are not easy to spray paint and are more prone to collision marks.

Prepare the floor wiper and cleaning agent first. Pour the cleaning agent into a bucket, add an appropriate amount of water, and stir evenly. Dip the floor scraper into the bucket, place the scraper on the ground, and push it from one end of the ground to the other end, scraping the dirt and water together to the other side. After scraping for a while, place the water scraper in a bucket and rinse thoroughly with clean water. Repeat the above steps until the entire floor is clean. Finally, dry the ground with a clean cloth or mop. matters needing attention: Before using the floor scraper, clean up any debris on the ground.When scraping the ground, it is necessary to maintain even force and not use excessive force to avoid scratching the ground.After scraping, clean the scraper in a timely manner to avoid residual stains.

(1) Grassroots treatment: The closed parts of circuit pipelines, cement repair parts, cement plastered walls, etc. need to be scraped with gypsum powder. Apply latex paint on the board, first apply anti cracking treatment, and then seal with varnish. Attention: The surface of the base layer should be polished flat, cleaned clean, and free from oil stains, dust, or bumps. (2) Fully apply putty twice: The first layer should be fully applied with a rubber scraper, and the horizontal scraping should be uniform, smooth, dense, and flat, with neat lines, corners, and edges. After the putty is dry, polish and scrape it; Then scrape the surface for a second time, dry it, and polish it flat and clean it thoroughly. Attention: When applying putty, try to scrape it as thin as possible without missing it. Do not stain the door and window frames or other parts. If there is any, it should be cleaned in a timely manner. (3) Bottom coating: The bottom coating should be applied on a dry, clean, and firm surface, and only needs to be sprayed once. Attention: When spraying, the coating must be uniform and cannot be missed. (4) Intermediate coating construction: If any unevenness is found before applying the first intermediate coating, putty should be used to level and polish it. Before using the coating, it is necessary to use a portable electric mixing gun to thoroughly mix and evenly mix. If it is too thick, it can be diluted with water appropriately, but the amount of water added each time should be consistent, and the thickness should not be inconsistent. Then pour the paint into the tray and apply the first coat with a paint roller dipped in the material. Note: The rolling coating sequence is generally from top to bottom, from left to right, with uniform thickness. (5) Emulsion paint surface spraying: Due to differences in base material, drying degree, etc., trial spraying should be conducted on local walls in advance to determine the compatibility between the base layer and the coating, and to determine the appropriate coating amount. Before spraying the latex paint, it is necessary to shake it thoroughly and then open the container to stir it thoroughly. Latex paint should be applied three times, and the spraying sequence should be: from the wall area to the column area, then to the pre surface area, and finally to the door and window areas. The painting rhythm should be consistent and the order should be flexibly controlled to improve spraying efficiency and quality. (6) Cleaning work: Wait until all construction procedures are completed before proceeding with the cleaning work. Firstly, remove some obstructions, and then remove any splashed materials during construction. This way, the latex paint construction is successfully completed.

To embark on a beautiful journey, start with a clean car interior environment. Do you know what items need to be cleaned inside a car? What we cannot ignore after buying a car is its maintenance. Generally speaking, the most basic maintenance of a car is usually car washing and inspection. However, people often overlook many issues when washing cars. 1. Center console The center console of a car is relatively large, which can easily accumulate dust and stains. We can use car cleaning brushes to remove dust, and use specialized cleaning agents to clean the surface and gaps of the center console. The dashboard lights can also be wiped with a soft cloth. 2. Steering wheel The steering wheel of a car often comes into contact with hands and requires frequent cleaning. We need to wipe it with detergent first, and then wipe it clean with a damp towel. 3. Car seats Car seats are relatively dirty places, and there are many remnants of things on the seats, so car seats need to be cleaned. After cleaning with a soft brush and cleaning agent, perform maintenance. Do not use coarse cloth or soap cleaner for cleaning. 4. Carpet Carpets are usually difficult to clean, so many people put foot mats on them. The foot mats can be cleaned directly, while the carpet needs to be cleaned with a vacuum cleaner, which is usually done in a professional place.

Wire brush is a very practical cleaning tool. After cleaning and polishing with wire brush, it can clean dirt, remove rust, remove surface paint, etc. The following are some applications of wire brush: 1. A steel wire brush can be used to clean stubborn dirt and stains on tiles and floors. First, use a steel wire brush to wash it several times, and then easily wipe it with a towel to make it look cleaner and cleaner. 2. A wire brush can clean kitchen utensils, such as removing grease and food debris from grills and baking pans. It can also remove dirt from the surface of the sink, keeping the kitchen clean and hygienic. 3. Wire brushes are commonly used to polish metal surfaces to remove oxide layers, rust, or dirt, making the metal look smoother and brighter. 4. A steel wire brush can remove old and mottled paint from the surface of an object. If you use a steel wire brush to rub the surface of the object multiple times, the paint will quickly fall off. 5. Wire brushes can also remove dirt and dirt from the wheels to keep them clean and smooth. In short, wire brushes are a widely used cleaning tool that can help us easily remove various dirt and stains and maintain a clean and hygienic environment. Select wire brushes with different materials, thicknesses, and hardness according to different work needs, such as stainless steel wire brushes, brass wire brushes, and nylon wire brushes. Before using, it is necessary to wear protective gloves, goggles, etc. When using a steel wire brush, it is necessary to pay attention to safety to avoid personal injury or damage to objects by the brush. After use, it should be cleaned promptly to avoid rust and corrosion caused by residual substances on the wire brush. It is best to place the wire brush in a dry and ventilated place to avoid deformation or rust caused by prolonged wetting of the wire brush.

1. Putty knife Putty knife is also known as scraper. Putty knife is the most commonly used tool in paint construction. It is easy to use and widely used in construction and life. Putty knife generally consists of blade and handle. The blade material is divided into carbon steel and stainless steel, and the common blade surface treatment is divided into ordinary polishing and mirror polishing. The handle is divided into wooden handle, plastic handle, iron handle and all-plastic putty knife. You can select the appropriate putty knife according to the user's habits and purposes. The size of putty knife we often say generally refers to the width of the flat edge of putty knife, which is usually divided into: 1 "(25MM).1.5"(38MM).2"(50MM).2.5"(65MM).3"(75MM).3.5"(90MM).4"(100MM).5"(125MM).6"(150MM).8"(200MM).10"(250MM). 2. Roller brush The roller brush is divided into three types: long hair, medium hair and short hair, which is represented by the length of the roller brush rather than the thickness and length of the roller itself. The brush hair is usually divided into wool and chemical fiber. Different roller brushes will paint different effects, and the long-hair roller will paint some fine texture, with a concave-convex feeling, similar to the texture effect. The paint surface after short-hair roller painting is relatively uniform, smooth, without concave-convex feeling, and the middle hair is between the two. The roller brush is mostly made of wool and foamed plastic, which can be divided into paint roller brush, roughening roller brush, floor paint roller brush, flat paint roller brush, etc. It is mainly used for large area paint roller coating of architectural decoration projects, and needs to be matched with the roller brush used in the paint tray. Due to the wide range of rolling surfaces, it is the most labor-saving and time-saving brush. It can also be used to paint and roll various mixed paints, such as latex paint, antirust paint, interior and exterior wall paint, wallpaper mounting adhesive, etc. 3. Paint brush The paint brush is widely used in our life. In addition to providing painting services for fiberglass, aerospace, food, ordinary families, etc., it can also be used for various kinds of glue and paint. The paint brush consists of handle, main material and auxiliary material. The handle can be divided into plastic and wood, and the plastic handle is usually formed by one injection molding; The wooden handle is mainly divided into log color handle and oiled handle. The main materials of the brush are mainly bristle, wool, and nylon imitation bristle. Auxiliary materials include tinplate, small nails and glue. The selection of paint brush is very important in the whole process of paint decoration. So, how do we choose paint brushes? 1. Select high-quality paint brush Paint brush processing materials mainly include wool, pig hair, elastic silk and other materials, and different materials have different characteristics. Before selecting, the first thing to be sure is that the quality of these materials meets the standard. 2. It is better to choose sheep tail hair When selecting wool brush, try to choose sheep tail hair as best as possible, and the manufacturing process of paint brush should choose the single production process. The quality of brush made by this processing technology is better. 3. Select the appropriate brush specification When selecting the paint brush, select the appropriate size and quantity of brushes according to the paint area and paint type. Generally, for large construction area, in addition to small brushes, large brushes should also be selected, and the combination of large and small brushes should improve the speed and quality of painting.

The roller brush is a common tool for painting. When you buy roller brushes, how do you distinguish the quality of roller brushes? First of all, we should understand that the quality of roller brush is determined by the plush density of roller brush: high-quality roller brush has a large plush density of more than 950 grams per square meter, a large amount of paint dipping, a large brushing area, a firm plush, not easy to fall off, and does not open the thread. Long service life, smooth rough surface. However, the density of plush of low-grade roller brush is below 700g per square meter. Weaving is loose and easy to shed wool. Secondly, according to the type of wool, 100% acrylic fiber is of good quality, good paint dipping and high price, while the wool containing a certain proportion of polyester fiber is cheap. The quality of the plush of the roller brush head determines the service life and effect of the roller brush. At the same time, 60% of the cost of a roller brush is determined by plush. According to the length of brush hair, it can be divided into three types: long hair, medium hair and short hair. The construction effect of roller brush is different according to the length of brush hair, as follows: The paint surface is relatively flat and smooth after the construction of short-hair roller brush. Fine concave-convex shape will appear after the construction of long-hair roller brush. The construction effect of medium hair roller brush is between short hair and long hair. There are also many sizes of roller brush, including 2 inches, 4 inches, 6 inches, 8 inches, and 10 inches. One inch is about 2.54cm. In case of large area construction, roller brush above 6 inches is applicable. The purpose of roller brush is to brush paint, floor paint, etc. It can also be applied with various emulsion paint, interior and exterior wall paint, anti-rust paint, wallpaper mounting adhesive and other mixed paint. The advantage of roller brush is that it is very convenient to use, and it can be applied directly and straight. If you want to apply evenly, the roller needs to be put into the paint bucket. After it is fully absorbed, roll it on the slope for several times, press out the excess paint and then start to paint the wall.

Many car owners take car washing as fun. Wash the car by yourself, study how to remove stains and keep the paint clean. It can not only increase the "communication" of your car, but also save a lot of money every year. It's really killing two birds with one stone. However, you should pay attention to several points when washing the car yourself. 1. The engine hasn't cooled down, so you can't wash the car immediately. Because the temperature of the engine hood just stopped is very high, if it is washed with water at this time, the aging of the paint will be accelerated. 2. Don't wash the car in the sun. Because the paint temperature is too high, the water on the paint surface evaporates quickly, and the water droplets on the body will leave spots, affecting the cleaning effect. 3. Without washing the car body with clean water, it is not allowed to wipe the car body directly with rags. The dusty rag will rub on the paint surface constantly, causing the car paint to be scratched, and eventually the paint surface will become "scarred". 4. Don't use a bucket of water to the end. Some people have the good habit of saving water, but it is better not to be too "stingy" with their car, because after washing the cloth several times, there will be a lot of dust and impurities in the bucket, resulting in damage to the paint surface in the process of wiping the car body, which outweighs the loss. 5. Do not add detergent randomly. It is not recommended to use laundry detergent, detergent and inferior soap when cleaning the car body, because these detergents contain alkali, which may damage the grease in the paint and accelerate the aging of the paint. Car washing steps: 1. Pre spray the wheel hub and tire parts with special automobile cleaner. Dilute the car washing liquid 1:10 into PA foam bottle to cover and spray the whole vehicle. Pay attention to the chassis and wheel arch mudguard parts. Wait for the foam to hang for about 3-5 minutes, and the pre washing can remove most of the sand and dirt on the body surface, reducing the chance of scratches. After sagging, wash the whole vehicle, pay attention to the distance between the water gun and the paint surface, and avoid spraying at a short distance due to high water pressure. 2. Brush the door hinge, guide channel, fuel tank cover, door frame, etc. with the special car cleaner and car detail brush. The accuracy of brushing can be improved by pinching the bristles at the edge seams. After brushing, wash with atmospheric pressure water immediately. 3. Dilute the car wash solution 1:400 into a bucket, put it into the filter element, and then use a water gun to make foam. Put another bucket into the filter element to prepare clear water. Use Chenille car wash gloves to dip in diluted car wash solution in the bucket to wipe and clean the upper part of the car body in a straight line to avoid repeated wiping at the same part. After cleaning 1-2 pieces of sheet metal, clean them in the clean water bucket in time. You can stick the car washing gloves on the dust collection filter element to rub, so that the sand and stone can fall to the bottom. In the same way, clean the lower wall of the vehicle body, and then clean the lower wall after cleaning the upper wall of the vehicle. 4. Use the special cleaning agent for automobile to cover and spray the four wheel hubs first, and use the special cleaning brush for tires to clean the wheel hubs and tires. Note: The car wash brush should be made of soft materials to avoid scratching the paint surface during the washing process. After cleaning a group of wheel hub tyres, wash them in time, and then proceed to the next wheel hub tyre cleaning. After scrubbing, wash the whole vehicle. Use a large water collecting towel to collect the body water to avoid water stains on the body.

The carpet and seat leather in the car will inevitably be stained during use. The plastic interior of the car will also be covered with dust due to long use. How can we keep the car clean so that the car owners can have a good car environment? Today, let's learn how to clean the car interior. Cleaning of dust on air outlet grille of air conditioner: It is easy to accumulate dust at the air outlet of the air conditioner. To remove the dust on the air outlet of the air conditioner, please do as follows: 1. Use the car cleaning brush to brush the dust on the lower air outlet, and wipe the falling dust near the cleaning part with a wring wet cloth while cleaning the dust. 2. We can use a wet cotton swab to clean the corners on the air outlet grille of some air conditioners. Note: The above operation can only remove the dust outside the air conditioner. The dust inside the air conditioner grille needs special tools to clean. Cleaning of plastic interior: To clean the plastic interior, we need to use car dust remover, soft dry cloth, special car interior cleaner and eraser. Specific methods: 1. Remove the dust on the plastic interior with the car dust remover. 2. Spray special interior cleaning foam on the plastic trim panel. After the foam has dissipated a little, you can use a dry cloth to wipe the trim panel until the foam is completely wiped off and the plastic interior becomes clean. 3. Some stains accumulated in the trench that are difficult to remove with cloth can be removed by gently wiping with an eraser. Cleaning of pile/cloth: Most roofs will use suede or cloth as interior trim. However, these two materials are mainly troubled by some water stains (caused by poor drainage of the sunroof) and dust adhesion. Specific methods: 1. First use a vacuum cleaner to remove the dust from the pile top. 2. Gently wipe the entire velvet top surface with a wrung wet cloth. Wait for the top to dry naturally. Pay attention not to use too wet cleaning cloth to wipe. Too wet cloth will make the pile top too wet and hard to dry, resulting in water stains or mildew. 3. For water stains, we can use interior cleaner to clean them. Cleaning of seat leather: Leather seats will accumulate many stains after being used for a long time. To remove these stains, special leather cleaner and soft dry cloth are required. Specific methods: 1. Spray an appropriate amount of leather cleaner on the leather seat to cover the leather surface. 2. Wait 3-5 minutes until the foam disappears, so that the leather cleaner can fully dissolve the stains. Clean the leather surface by wiping away the dissolved stains and leather cleaner with a soft dry cloth. Carpet cleaning: Vacuum cleaner, stick, interior cleaner and dry cloth are generally used to clean carpet. Specific methods: 1. First, use a vacuum cleaner to remove large particles of dust and stones. 2. Take out the carpet and beat it with a stick to remove dust. 3. For some water stains and slight stains, we can use interior cleaner to remove them. 4. Never use strong detergent or wash the carpet with water, the former will cause the carpet to fade, and the latter will damage the carpet.

It is well known that the tires and wheels of cars are often polluted by dust, mud and dirt on the ground, which makes the car very dirty. Proper cleaning of the tires and wheels is the key to keeping the car clean. If you use a hard brush to clean these dirt, it is easy to damage the car and cause scratches. So how can this part be cleaned correctly and easily? When washing the tires, we need to prepare a car washing brush with a long handle and moderate bristles, so as to thoroughly clean the tires and wheels. When washing the front wheels, turn the steering wheel left and right so that all parts of the wheels can be washed more easily. If the tires are not too dirty, they can be washed with a general detergent If there is a lot of dirt and it is difficult to clean, you need to buy a special cleaning agent and match it with a suitable car wash brush to clean it quickly. Note: when cleaning the tire, the mirror treated rim can be cleaned with a soft brush or sponge to prevent scratches. Some inconspicuous places such as the lower side of the oil tank and the exhaust pipe are often easy to be ignored. We can use detergent and brush or sponge to scrub when cleaning. In the appearance of the car, as long as the above parts are cleaned, the overall appearance of the car will be completely new. Even if some small stains on other parts are not cleaned, the overall appearance of your car will not be affected. Finally, we should note that the tools for cleaning different parts of the car should be distinguished, because the cleaning requirements of different parts of the car body are different. For example, the tires are dirty. After cleaning the tires, there may be some dust or small sand left on the tools. If these tools are used to clean other parts of the body, scratches may be caused.

Emulsion paint is the wall decoration material that we will use when decorating the wall. The work of painting emulsion paint is not difficult. You can operate it yourself without asking workers. This not only increases our sense of participation in home decoration, but also saves a sum of decoration expenses. However, many people still don't know the difference between rolling and spraying emulsion paint. Is it better to use roller coating or spraying emulsion paint? 1. Technical requirements: the technical requirements of rolling emulsion paint on the construction personnel will be relatively high, mainly reflected in the weight of water and the force of rolling coating. If the construction personnel do not master it well, the effect of rolling coating will be poor. The technical requirements of spraying will be relatively low. 2. Brushing texture: the paint film of rolling emulsion paint will be relatively thick, and the texture and scrub resistance after construction are relatively good. Spraying is to use the power of the spray gun and nozzle to spray the paint on the wall. The effect of the surface is relatively uniform and will not leave brush marks, which is impossible for roller coating. 3. Repair difficulty: the paint film of roller coating is relatively thick, so it is easier to repair later; The paint film sprayed is relatively thin, and it is not easy to repair once it is damaged. 4. Usage of emulsion paint: it will be more economical to brush emulsion paint by rolling, while the spraying construction method will be more wasteful of materials, especially when a variety of colors are mixed, the colors are easy to interfere with each other, so that the overall visual effect will be reduced. To sum up, the construction method of rolling emulsion paint is more suitable for the construction of mixed colors, which will not cause mutual interference between colors, and the paint film is relatively thick. Even if there is damage in the later stage, it can be repaired. It is suitable for multicolor emulsion paint walls in modern decoration. Single color emulsion paint can be applied by spraying. For example, painting emulsion paint on the top surface by spraying can be faster and save manpower. Finally, it is very important that when painting the wall with emulsion paint, we must wait for the previous emulsion paint to dry before proceeding with the next construction, so that the painted wall has the best effect. Whether the emulsion paint is painted by rolling or spraying needs to be decided by everyone according to the actual situation of their own decoration.

After the steel is rusted, the rust is loose, and the adhesion with the metal surface is not firm. The paint coated on the rust will inevitably cause the coating to fall off, resulting in the failure of the anti-corrosion coating. Derusting can be said to be a process that cannot be bypassed by any coating process. Derusting methods can be divided into chemical and physical methods. 1. Chemical derusting: immerse metal components in acid solution, and remove rust, oxide skin and various corrosive substances on the metal surface through chemical reaction. Common acids for pickling include hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid and hydrofluoric acid.Chemical derusting is generally used in factories, and some small parts are used more. 2. Physical derusting: physical derusting can adopt manual derusting, power tool derusting, sand blasting derusting, flame derusting, high-pressure water flushing derusting, etc. manual rust removal: use abrasive cloth, hammer, shovel, scraper, wire brush and other tools to remove rust, which is simple and convenient for construction, but it has high labor intensity, poor rust removal quality and low efficiency. This method is applicable to the trimming of individual parts or other local derusting treatment. power tool derusting: use electric grinder, pneumatic grinder and other tools to drive the grinding wheel, sandpaper tray, steel wire tray, etc. for derusting. Generally, power tools can remove all loose oxide skin, rust, old paint film and other harmful substances, but they cannot remove the oxide skin, rust and old paint film firmly attached to the steel surface. Sand blasting and derusting: a rust removal method that uses high-pressure air to bring out abrasive and spray it onto the surface of components. Open sandblasting has great environmental pollution and impact on other operations. It is troublesome to clean the site and has serious environmental pollution. Recently, its use has been gradually restricted. Vacuum sand blasting is to use vacuum to immediately recover the sprayed sand. This method is used for local rust removal. Sand blasting is divided into dry sand blasting and wet sand blasting. Dry sand blasting: use 0.5-0.7mpa compressed air to drive sand or steel sand, and spray it to the steel surface at high speed to remove rust, oxide skin and various corrosive substances on the metal surface. And make the substrate have a certain roughness. Wet sand blasting: use compressed air to take out the wet abrasive and spray it on the steel surface at high speed to remove rust, oxide skin and various corrosive substances on the metal surface, which solves the problem of dry sand blasting pollution, but there will be flash rust on the surface of the substrate, so corrosion inhibitor should be added. high pressure water flushing and derusting: take water as the medium, form high pressure through the high pressure generator, and then spray it quickly. The water jet forms a highly concentrated energy, which impacts and grinds the cleaned metal surface like a water arrow. The rust layer and scaling are mostly distributed in layers or multi pores. Once the scale layer is penetrated, the ultra-high pressure water jet is wedged between the scale layer and the metal surface, which can remove the oxide skin, old coating, etc. on the workpiece surface, including very hard corrosion products. The effect is better after adding abrasive in water. flame derusting: flame derusting is one of the derusting processes. The code of flame derusting is ft. the main process is to shovel off the rust layer on the surface of the substrate, then bake or heat it with flame, and clean the heated surface with a power wire brush. This method is applicable to the removal of old anti-corrosion coating (paint film) or metal surface engineering with oil immersion. It is not applicable to thin-walled metal equipment and pipelines, nor can it be used in the rust removal engineering of annealed steel and hardenable steel.

Paint brush is a tool often used in daily life and manual operation. The paint brush can be used not only to brush paint, paint and glue, but also to clean the dust at the root of the wall, corners or cracks. According to different materials of bristles, paint brushes can be divided into three types: pig hair brush, wool brush and nylon fiber brush, which are mainly the difference between the degree of paint and the degree of hardness and softness. According to different shapes, it can be divided into flat paint brush, round paint brush, crooked handle paint brush, etc. Flat paint brush: it is composed of wood handle or plastic handle, brush hair and rectangular cylindrical thin iron clamp. The brush hair is made of bristle and can be divided into 1 ", 2", 3 ", 4" and other common sizes according to size. This is the most commonly used brush, which is cheap and can be used for painting oily paint. Round paint brush: it is composed of round wooden handle or plastic handle, round bristles and thin iron clamp. Bristles are mostly made of bristles. The specification of the circular brush is expressed by the diameter of the circular bristles. It is used in conjunction with the flat brush to brush the parts with complex shapes. Elbow paint brush: it is composed of wood handle or plastic handle, bristles and thin iron clamp. The bristles are flat. The curved wood handle is usually 45 ° skewed, and the handle is long. It is used in conjunction with the flat brush for the parts that are difficult to be painted by the flat brush. Summarize how to select and maintain paint brushes: 1. appearance No matter what kind of brush, it is required that the front end of the bristles should be neat without shedding. 2. coating characteristics If it is a high viscosity coating, such as magnetic powder paint, ready mixed paint, etc., the key point is one word, hard! Just choose a hard brush. If it is a coating with low viscosity, such as various varnishes, you can choose a thin hard brush or soft brush. For water-soluble paint and polyester paint, wool brush with good paint property shall be selected. 3. coated surface For the coated objects with rough surface, such as the cross section of metal castings and wood, the circular paint brush can be selected. Because the circular paint brush contains a large amount of paint, it is easy to make the paint wet the rough surface and penetrate into the holes. 4. brush maintenance After using the paint brush, the paint brush shall be cleaned and dried in time. If the paint brush is not cleaned in time and exposed to the air for a long time, it is easy to harden and scrap.

1. surface treatment before painting is very important The main reason for the failure of painting is that proper surface treatment is not carried out before painting. According to the different conditions of the painted surface, the surface treatment can include: cleaning, maintenance, repair, grinding, masking and primer. 2. primer shall be applied before painting In order to obtain the best brushing effect, some surfaces shall be primed before brushing. This shall be determined according to the specific conditions of the construction site and the brushing materials. 3. application amount In addition to choosing the right product and color, you also need to estimate the amount of paint required. This requires first calculating the area to be painted, and then dividing it by the approximate coating rate of the paint you use. In most cases, it is better to prepare a little more paint to avoid going out to replenish the goods in the middle of the work. 4. be sure to remember the protection of finished products Remove small pieces of furniture, curtains and photos, and cover large items and floors with covers; When painting, especially when alkyd paint and oily paint are used, doors and windows shall be opened to circulate air. 5. dilute the paint in proportion If you like the darker room space, you will naturally choose the darker paint. It should be noted that when using the darker paint, you should try not to add any thinner to the paint, so as to ensure that the paint we use does not have color difference to a large extent. If you do not pay attention to the color difference, the whole room will be very ugly. If it needs to be diluted, it must also be diluted according to the proportion specified in the product description. 6. pay attention to the change of air humidity Pay attention to the change of air humidity during painting. If the humidity is too high, the paint will dry very slowly, which will not only affect the progress of the project, but also affect the quality of painting during decoration; If it is too dry, the paint will dry too fast, and cracks will appear. That is not worth the loss. 7. the paint brush shall be of good quality Some paint brushes are of poor quality and are prone to hair loss. When painting with such brushes, the brush hair is often hung on the paint surface. After the paint film is formed, it is left on the paint, which has a great impact on the effect of the paint. Therefore, when painting, try to use a better quality paint brush. If it is a new brush, pay attention to remove the hair that is easy to fall off on the brush. 8. do not paint too thick once The paint shall not be applied too thick at one time, otherwise it will cause the paint to flow and look uneven. If this happens, it can be polished with sandpaper. 9. wait until the paint is completely dry The second coat of paint must be completely dry after the first coat of paint is brushed, otherwise it is easy to wrinkle the paint film. 10. nail holes on the surface of wood products shall be repaired In the process of woodworking, whether ordinary iron nails or air nails are used, nail holes will inevitably be left on the surface. One of the important tasks of painters is to repair the nail holes, otherwise it will not only affect the visual effect of wood products, but also affect the service life of wood products.

Latex paint is a kind of waterborne coating made of synthetic resin emulsion, with pigment, filler and various auxiliaries. It has the advantages of easy to brushing, rapid drying, water resistance and good scrubbing resistance. It is widely used in modern home decoration. So does the latex paint contain formaldehyde? Any paint used in people's decoration should take benzene series as the production raw material, just as there must be formaldehyde in the glue. There is no formaldehyde free glue and formaldehyde in the real sense, but only the addition within the scope of safety and environmental protection. Therefore, latex paint contains a certain amount of formaldehyde, because formaldehyde has the function of sterilization and corrosion prevention. Generally, the formaldehyde content of latex paint that can be sold is within the scope of national standards, so it can be used safely. In addition, emulsion paint is a water dispersible coating, and their film performance is much better than that of solvent based coating, while the organic solvent accounting for half of solvent based coating is replaced by water here. Therefore, the toxicity of organic solvents is basically completely solved by latex paint. When purchasing latex paint, we should pay attention to the outer packaging and environmental protection test report. Regular products will be marked with product name, trademark and description of product composition. In addition, we should also pay attention to its production date and shelf life, and ask businesses to show environmental protection test reports. When buying, you can take up the emulsion paint bucket and shake it. If it is very prone to noise, it indicates that the viscosity of the product is not enough. It is best not to buy this kind of emulsion paint. Try to choose environmentally friendly latex paint products. Don't be greedy for cheap. You must choose products of regular brands. People often say that formaldehyde poisoning is caused by the high content of formaldehyde in the purchased coatings or furniture. After painting emulsion paint, it is recommended to keep ventilation for about 1 month. If there are old people, children and pregnant women at home, it is best to keep ventilation for 2-3 months.

Many women love manicure, but some people do not have time to go to the manicure shop, and they often choose to paint their nails. So the skill of nail polish is very important. To do a good-looking manicure, pay attention to the following steps. 1. If you want nail polish evenly, make sure your nails are smooth and smooth. Girls whose nails are not smooth can polish them flat and smooth with a nail polishing rod. 2, before applying nail polish, gently shake the nail polish bottle and dip the nail polish into the nail polish. Be careful not to dip too much. Taking too much nail polish at a time will make the nails look heavy after being painted. It will be difficult to master when they are painted, but not good. Before applying the dark nail polish, you must first apply a layer of base oil to protect your nails while making the nail surface smooth and prevent decolorization. 3. When you apply nail polish, you can first apply it from the middle of your fingernails. Nail polish brush begins to smear around the edge of the nail about 2mm. Note the most important point: when you apply nail polish, you need to split the brush head into fan-shaped, so that the nail polish can be more evenly coloured on the nail surface. Under normal circumstances, a brush on the middle part of the nail is enough. Next, paint both sides, starting from 2mm away from the edge of the nail, and gradually apply force to separate the brush head during the coating process. This method covers a large area and can avoid overlapping stripes. After the first nail polish is dry, you need to apply second times nail polish, because this can make the two layers of nail polish naturally blend, and the color effect is better. However, four or five layers of nail polish can not be applied repeatedly for the sake of color rendering. 4, after the nail polish is dry, you need to apply a layer of quick drying brightening oil, which can increase the brightness of nails.
