More and more decorative aluminum coils appear in people's life in the market. The surface treatment of aluminum coils can improve the decorative, corrosive and functional use of products. As an aluminum coil manufacturer, we have advanced technology and deep understanding of aluminum coils.
1. During the pretreatment, the surface cleaning method, physical and chemical methods can be used. The most important thing is to expose the insulated aluminum coil to the substrate. This is conducive to the integrity of oxidation, and the formed oxide film will be relatively dense. Pretreatment can also be carried out with some mechanical equipment.
2. Anodizing. After the treatment of insulated aluminum coil, the substrate undergoes anodizing reaction, forming a dense oxide film.
3. Seal the hole. After anodizing, many film pores will appear on the oxide film. The oxide film is transparent and adsorbed. It deposits some metal salts in the pores, revealing some original silver white or many colors outside.
Through these steps, you can see that the aluminum coil is painted through these, making our building more colorful.
