Common surface treatment methods of aluminum profile | Sdql-alu.com
In order to increase the corrosion resistance and mechanical properties of the aluminum surface, various surface treatment methods shall be carried out for aluminum profile after extrusion.The common surface treatments of industrial aluminum profiles are as follows: 1. Anodizing: This is a common surface treatment method for industrial aluminum profiles. The principle is to form an oxide film on the surface of the profile. The advantage is that it can increase the profile's anti-corrosion and wear resistance, and has an insulating effect. It is suitable for a variety of industrial production fields and can play an anti-static effect. 2. Electrophoretic painted aluminum profile: Electrophoretic paint film has the advantages of fullness, uniformity, flatness and smoothness. The hardness, adhesion, corrosion resistance, impact performance, and permeability of the electrophoretic paint film are significantly better than other coating processes. 3. Powder spraying: (1) H...
