aboutMolecular structure of PVDF fluorocarbon coatings:

The fluorocarbon aluminum veneer, as we often say, is made of aluminum plate in essence, and then PVDF fluorocarbon baking paint is applied on the surface of the board. This coating uses fluorine atom and polyvinylpyrrolidone in aliphatic hydrocarbon molecular structure,The binding force between fluorine atom (f) and carbon atom (c) with the largest negative charge is more than 105.4kcal/mol, that is to say, it needs at least 105.4kcal/mol energy to break the binding between fluorine and carbon. The molecular binding distance of fluorine and carbon is 1.36a, which is shorter than that of carbon and carbon (1.54a). Because of the steric hindrance of fluorine atom, the coating structure is very close. This is also the reason why the fluorocarbon baking paint is more durable than the general coating.

Based on the above reasons, generally outdoor decorative aluminum plate manufacturers will recommend customers to use fluorocarbon coating for surface treatment, because the fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt fog and various air pollutants, excellent cold and hot resistance, can resist strong ultraviolet radiation, long-term color fading, no powder, long service life, very suitable for Outdoor use.

The advanced imported CNC punching machine and CNC engraving machine of hongaluminum building materials strictly comply with the design requirements and complete the operation accurately and efficiently. High quality aluminum alloy panel is used as the base material, and advanced numerical control bending technology is adopted to ensure that the plate can be flat without deformation after processing, and the external force resistance performance is superior in the installation process of aluminum veneer. The surface coating of fire-proof aluminum veneer system of honglv Aluminum Co., Ltd. adopts American Lanchester fluorocarbon spraying equipment and American Aksu fluorocarbon (PVDF) coating to ensure uniform surface color, ultraviolet radiation resistance, oxidation resistance, super corrosion resistance. The aluminum veneer manufacturing center has strong processing power and strong technical force. It has a number of German numerical control plate shears, CNC bending machines and American stud welding machines Good skilled workers, highly skilled, is a well-known special-shaped plate processing manufacturers.
