Most of traditional building decoration materials adopt stone materials and gypsum boards, the building cost is increased due to the fact that the decoration materials are heavy in weight, complex in installation and processing technology and simple in modeling, and the design intention of a building designer cannot be well expressed due to the limitation of the performance of the materials. Due to the excellent processing performance, the light weight, the low price and other factors of the aluminum veneer, the aluminum veneer can be widely applied to the field of building decoration, the material and installation cost is greatly reduced, and the construction period of a building is shortened. In recent years, with the demand of market development and the improvement of industrial product grades, people have higher and higher requirements on various performances of the aluminum veneer, however, the performances of the aluminum veneer are closely related to the manufacturing process of the aluminum veneer.
The fluorocarbon coating has high chemical corrosion resistance, heat resistance, weather resistance and durability, and is inactive to a plurality of acids, alkalis and solvents, so the fluorocarbon coating is widely applied to the field of building decoration.
