How to maintain the anode oxide film of aluminum alloy profiles

After the chemical or electrochemical polishing, then the anodizing treatment, the aluminum products will obtain a smooth and bright layer of oxide film, with a high transparency, at this time, the aluminum alloy surface is easy to obtain various colors by dyeing. In the field of industry, the anodizing treatment or chemical oxidation methods are becoming more and more widely used, it makes aluminum alloys to obtain a layer of oxide film, and to achieve a purpose of protection and decoration.
