　　How to use and maintain the roller brush?

　　Most of the current roller brushes are made of acrylic velvet or foam plastic with an I-shaped iron handle. They are used for large-area paint roller coating. They are an ideal tool for architectural decoration and decoration projects. Paint, organic or inorganic exterior paint, anti-rust paint, wallpaper paste and other materials.

　　Instructions:

　　(1) Dip a clean roller brush into the paint bucket. After it has inhaled an appropriate amount of paint, it can be rolled on the work surface. Firstly, the roller coating is applied horizontally. As the coating on the roller brush is reduced, the rolling speed can be appropriately accelerated. When the coating on the roller brush is basically used up, the roller is rolled in the vertical direction, and the uneven coating is leveled until the spine is coated. . If you need good gloss, you can use a brush to brush it again.

　　(2) The used roller brush does not need to be washed. Just soak it in paint or clean water and continue to use it the next day. When a project is completed, it can be washed with gasoline or thinner. Generally, it can be cleaned in the paint tray. After the cleaning is completed, the sleeve is dried and the fluff of the tube is loosened to avoid entanglement of the piles during storage. When storing, wrap the sleeve with kraft paper. The kraft paper is slightly wider than the sleeve and the excess is stuffed into the sleeve. It can also be wrapped in a plastic sheet, but it is perforated to allow air to circulate to prevent mold. The sleeve should be stored upright, otherwise the fluff will be pressed, the foam roller brush can not be cleaned with gasoline, and it should be wrapped with paper after cleaning.

　　How to buy a good quality roller brush

　　Plush:

　　Everyone knows that the roller brush is used to paint paint. Then, the plush of the roller brush is the key to the quality of the roller brush.

　　Density:

　　High-quality roller brush, high density of plush, more than 950 grams of flat rice, large amount of varnish, large brushing area, firm plush, not easy to shed, not open. Long use time, smooth surface. The low-grade roller brush has a pile density of less than 700 grams per square meter. The weaving is loose and extremely easy to shed.

　　Purity: 100% acrylic fiber, good quality, good immersion paint, high price, and the price of plush containing a certain proportion of polyester is cheaper.

　　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 the plush.

　　How to distinguish the advantages and disadvantages of plush? As far as China's current roller brush manufacturing industry is concerned, roller plush can be roughly divided into three categories: shuttle weave (horizon weave, warp and weft weave), weaving, and circular weave. Among them, the quality of the shuttle weave method is the best, the price is also high, and the product of the circular weaving method is relatively low.

　　According to China's current situation for the plush textile industry, the shuttle machine is a huge machine because the imported double rapier looms are too expensive. At present, there is only one factory in Shandong, and warp knitting products are currently There are already five or six factories in China. The machine cost of the circular machine is relatively cheap, and there are hundreds of factories in China that can be produced.

　　The earliest German roller brush products are shuttle products. The earliest roller brush products exported from China to Europe are also shuttle products. At present, European customers require strict quality products, which are also shuttle products.

　　The resolution is simple: separate the plush, see the density of the ground cloth and the weave. Plush material. High-grade sheepskin, wool, and nylon. Acrylic fiber, etc. The low grade is polyester, polyester blend and so on.

　　Structure: In addition to the plush, the internal structure of the roller brush is also very important. At present, it can be divided into three categories: one is the German plunger structure, the other is the American roller frame structure, and the third is the Chinese screw structure.

　　The advantages and disadvantages of the German plunger structure are: the handle is simple and cheap, but the brush head is complicated and expensive. Can be used interchangeably. The advantages and disadvantages of the American roller frame structure are: the brush head is simple and cheap, but the roller frame is complicated and expensive. Can be used interchangeably. China's screw-type structure is simple to manufacture, low in price, uneven in quality, and difficult to replace the brush head. The handle is a one-time product. The use of waste is costly for the user. The products of individual factories, because there is no inner tube, there is a phenomenon that they can flow in and paint out. There is also the phenomenon of falling off the cover and fluffing off.

　　Plastic material:

　　The requirements for exporting to European products are nylon tubes and new material handles. The new material is blocked and the environmental protection requirements are strict.

　　Adhesive:

　　German formula special adhesive. Ordinary adhesives, etc. The use of these materials directly affects the use of the roller brush. German formula special adhesive is resistant to thinner acetone, Tianna water and so on. Ordinary adhesives are not resistant to use, especially for high-grade paints, and for the application of relatively thick adhesives, low-grade roller brushes cannot be used.

　　Testing method:

　　The fleece is torn from the inner plastic part of the drum by hand, and the good quality roller is difficult to break. Poor quality is easy to tear off. Contact: Zero five 叁肆贰叁 捌 捌 捌 捌 捌.

　　Carrying test:

　　A good quality roller brush, one person stepping in the middle of the roller head. The roller brush can bear the weight of one person. There is no change in the roller brush. The poor quality roller brush is pinched by hand and the plastic parts inside are broken.

　　Process manufacturing:

　　The rough surface of the roller brush is flat, no gap, no bag, no bristle.

　　In addition, there are drum diameters, handle diameters (4-8mm), plastic parts, plating, etc.

　　There are many sizes of roller brushes, how should I choose?

　　A: The common roller brush lengths include 2, 4, 6, 7, 8, 9, 10 inches, and an inch of about 2.54 cm. For large-area construction, you can choose a roller brush of 7 inches or more, and a roller brush of 6 inches or less. Construction of small areas and construction of corners and narrow areas.
