According to the quality requirements of the products, we need to adopt different production processes in the production process, so the production line of color coated panel can be divided into the following categories: ordinary building materials board of the production line of color coated panel is made of polyester paint as top paint, which is combined by roller coating process of one coat, one coat, one bake or two coat and two bake.
It has excellent corrosion resistance, mechanical properties and ornamental decoration. After pressing, compounding and other processes, colour panels form a variety of new building materials, which are used in various emerging industrial buildings. The production line of coated color coated sheet for household appliances is made of galvanized sheet or hot-dip galvanized sheet with thinner zinc layer as the base plate, which is combined by three-coated and three-baked roll coating process or coated with a decorative film.
The production line of fluorocarbon color coated panel adopts fluorocarbon coatings mainly composed of polyvinylidene fluoride (PVDF). Because the maximum electronegativity of fluorine atoms forms a very stable high-performance fluorocarbon bond and its unique isosymmetric molecular structure, the fluorocarbon color coated panel has excellent weatherability and is suitable for modern high-grade buildings.
Printing and dyeing coating process is adopted in the production line of printing and color coating plate. Gravure printing roll of finishing machine transfers pattern to coating roll to realize printing, such as wood pattern pattern, and then coats bright paint or anti-ultraviolet protective film on the other side. Printing process is mainly to improve the decoration of coated steel plate and increase the sense of reality.
