Anodizing of aluminum plate can improve the corrosion resistance, surface hardness and wear resistance of aluminum alloy products, and has a good decorative effect after coloring treatment.
The anodic oxidation of aluminum plate is mainly the anodic oxidation of aluminum, which is the process of forming a dense oxide film on the surface of the aluminum plate under the electrolyte solution by using the principle of electrochemistry, which is called surface anodic oxidation.
The process flow of anodized aluminum plate is mainly from degreasing→etching→neutralization→anodizing→coloring→sealing.
