Anodized aluminum nameplate

As is known to all, aluminum oxide film has valuable corrosion resistance, stability and color absorption and a series of advantages in the nameplate protection decoration has been widely used.Therefore, it is unnecessary to repeat its mechanism, equipment and general operation method.

Aluminum oxide electrolyte, although there are oxalic acid, chromic acid and sulfuric acid types, from the nameplate process practicality and decorative considerations, only the application of the most popular sulfuric acid electrolyte process specifications are introduced here;At the same time, it also introduces some new technological methods for the practical application of nameplate production.

Sulfuric acid solution oxidation is the most typical method in nameplate industry, which has the following characteristics.

(1)?The film layer is thicker, the surface color is transparent colorless, strong adsorption, is conducive to a variety of bright colors.

(2) simple process, short oxidation time, high production efficiency;

(3) the tank is cheap, stable solution, easy to grasp;
