How to perform oxidation treatment on aluminum cylinder barrels

In the production process of all aluminum pneumatic aluminum tubes, there is a process called surface treatment. Do you know why pneumatic aluminum tubes need to be oxidized? The purpose of surface treatment of aluminum pipes is to solve the three problems of corrosion resistance, decoration, and functionality of profiles.

Before surface treatment of aluminum tubes, it is necessary to polish the cylinder tubes, which can be divided into three methods: chemical polishing, electric polishing, and mechanical polishing. Chemical polishing and electro polishing are performed after the first use of mechanical polishing to achieve the bright effect of the cylinder tube, and to maintain the same brightness even after surface oxidation.

There is a special surface treatment method called aluminum conversion coating process, and Chen Zhi refers to "chromate conversion coating on aluminum and all aluminum pipe profiles.". The aluminum profile produced by this method can not only achieve conductivity, but also enhance the protective ability of aluminum. The protective effect of aluminum is a technology specifically studied to enhance its conductivity and protective ability. This method has low technicality, low processing cost, and good processing performance, and is widely used in the military electronics industry.


There are multiple oxidation methods available. Before surface treatment of aluminum pipes, different oxidation treatment processes should be selected according to their respective requirements:
