[China Aluminum Industry Network] Aluminum products are common materials in daily life, but many people do not understand aluminum surface treatment technology. The following surface treatment technologies for aluminum materials are mainly based on different requirements. Treatment process.
1. Anodizing - The dead oxide film on the surface of the aluminum plate can effectively improve the protective performance of the aluminum plate. The oxide film is not conductive and does not apply to the requirements of conductive conditions.
2, after the anodizing (hair) color - to form a variety of colors on the oxide film to meet certain requirements, such as optical instruments commonly used black parts, medals on the golden and so on.
3, conductive oxidation (chromate conversion film) - for both protective and conductive applications.
4, chemical oxidation - for general protection, easy processing, low cost.
5, coated with organic protective layer (paint, spray, etc.) - for the external protection of equipment, decoration, usually carried out on the basis of oxidation.
Other preparations such as polishing (mechanical, electrochemical, chemical), sandblasting, etc. may be performed prior to the upper surface treatment to enhance the above surface treatment functions.
