Surface requirements for aluminum alloy products

According to the demands of different choice of different surface treatment processes:
1 anodic oxidation of — — life and death oxide film on the surface of the aluminum plate can effectively improve the protection performance of the aluminum sheet. Oxide film is not conductive.
2 anodic oxidation after the (hair) color — — in the oxide film on the formation of a variety of colors, to meet certain requirements, such as optical instrument parts used in black, in commemoration of the golden yellow, etc..
The 3 conductive oxide (chromate conversion film) — — for both protective and conductive.
4 chemical oxidation of — — used for general protection, easy processing, low cost.
5 coated organic protective layer, paint, plastic, etc.) & mdash; & mdash; for equipment outside the door, decoration, usually in oxidative base.
Other preparation before the surface treatment, such as polishing (mechanical, electrochemical, chemical method), sand blasting, etc., can strengthen the function of the surface treatment.
