Why should oxidation treatment be carried out on aluminum profiles ？
There is a process called oxidation treatment in the production process of industrial aluminum profiles. Do you know why aluminum profiles need to undergo oxidation treatment?
The purpose of aluminum surface treatment is to solve the problem of providing anti-corrosion and aesthetic properties of aluminum profiles.
Before surface treatment of aluminum profiles, it is also necessary to polish the aluminum material
And polishing can be divided into three methods, namely chemical polishing, electric polishing, and mechanical polishing
After using mechanical polishing first, chemical polishing and electric polishing can achieve a smooth surface of aluminum material, and can still maintain smoothness and brightness after surface oxidation
The surface treatment process is called aluminum oxide film, which is called "aluminum and aluminum alloy Chromate and dichromate conversion film"
The aluminum profile produced by this method can not only achieve conductivity, but also enhance the protective ability of aluminum. It is a technology specifically studied to enhance the conductivity and protective ability of aluminum
This method has low technicality, low processing cost, and good processing performance, and is applied in the field of intelligent electronics.
There are various methods of oxidation, and before surface treatment of aluminum profiles, different oxidation treatment processes should be selected based on the product requirements
1. Anodizing: A dense alumina film is produced on the surface of the aluminum tube to react with air again, improving the protective performance of industrial aluminum profiles. At the same time, the oxide film isolates free ions inside, making it unable to conduct electricity.
2. Coloring after anodizing: industrial aluminum profiles form various colors on the oxide film to meet certain use requirements. If they are used in industrial machinery industry, industrial robots, assembly line workbench, equipment rack, they can be oxidized to silver white and sandblasting electrophoretic color.
