The process of aluminum oxidation surface treatment
After the aluminum is in contact with air and water, it is easy to rust and damage, and it is easy to be damaged by oxidation. In order to protect the aluminum, the process treatment needs to be carried out. What is the process of aluminum surface oxidation treatment?
The main process of aluminum profile surface treatment includes:
First, degrease the aluminum profile products before aluminum profile treatment in order to remove the protective oil layer on the surface of aluminum profile and ensure the uniformity of the surface during post-treatment (Our degreasing agent can be used)http://www.gdhaihuachem.com/product/acidic-degreasing-additive
Second, after degreasing, the aluminum profile must be subject to Acidic etching treatment to remove the oxide on the surface of the aluminum profile (Our acidic etching can be used)http://www.gdhaihuachem.com/product/acidic-sanding-additive
Third, after the acid etching treatment, the alkaline etching treatment shall be carried out to remove the oxide on the surface of the aluminum profile and the indentation left during the extrusion process (Our alkaline etching agent can be used)http://www.gdhaihuachem.com/product/alkaline-etching-additivesolid
Fourth, after acidic etching and alkaline etching, a layer of ash layer of mixed elements will remain on the surface of aluminum profile, which must be removed by mixed acid to expose the essential color of aluminum profile(Our neutralization agent can be used)http://www.gdhaihuachem.com/product-list/aluminium-neutralizing-additive
Fifth, if the customer needs electrolytic coloring aluminum, the aluminum needs coloring treatment(Our coloring stabilizer series products can be used)

Sixth, start to oxidize the aluminum profile, attach a layer of protective film to the surface of the aluminum profile, and enhance the corrosion resistance of the aluminum profile products;
Finally, after the oxidation of aluminum profile products, small pores will be generated on the surface, which should be sealed. (Our Cold sealing agent or medium temperature sealing agent can be used)
