People choose the above based on the application because the color-coated board carries out strict control of each process in the production and manufacturing, and ensures the symmetrical quality in terms of appearance, durability and process performance. Mass-produced color-coated panels are cheap. Compared with the coating solution of finished products, the liquid component of architectural coatings has high water content, and the consumption of organic chemical architectural coatings is low, which is cost-effective for economic development. The application of color-coated plates can greatly simplify the production process, and there is no organic chemistry to solve the air pollution caused by painting and baking. The types of architectural coatings usually used include epoxy resin, polyester, silicone modified material polyester, polyvinylidene fluoride, and polyurethane materials.
People choose different substrates or different types of architectural coatings based on the natural environment and main purpose. For general engineering and building exterior coating, the colorful coating thickness of hot-dip galvanized substrates should be used. Steel plate. When used as a corrugated board in engineering and construction, it is best to use a color-coated board produced by 2 coatings and 2 baking on the upper and lower layers. When making color steel sandwich panels, use the upper surface as a secondary coating.
Color-coated panels have lightweight concrete, beautiful appearance and excellent corrosion resistance, and can be produced and processed immediately, so they can be used in the construction industry, shipbuilding industry, car processing industry, home improvement industry and electrical equipment manufacturing industry. Hot-rolled steel sheets and galvanized sheets are the substrates, which undergo surface normalization treatment, are coated with architectural coatings in a continuous manner, and are baked and cooled by water.
