Wide Application of Anodized Aluminum Plate

Anodized aluminum plate is to place the aluminum plate in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and conduct electrolysis under specific conditions and applied current. Chemical aluminum oxide plate is a treatment process in which part of the base metal reacts in weak alkaline or weak acidic solution to thicken the natural oxide film on its surface or produce some other passivation films. The commonly used chemical oxide films include chromic acid film and phosphoric acid film, which are thin and have good adsorption and can be colored and sealed.
