Anodizing machine/ Aluminum anodized machine/ Ti Alloy anodizing machine

Working principle

Aluminum or aluminum alloy products for the anode, placed in the electrolyte solution for power treatment, the use of electrolytic effect to form a film of aluminum oxide on the surface of the process, known as aluminum and aluminum alloy anodizing treatment. After the anodic oxidation treatment, the surface of aluminum can generate 1um-500um oxide film. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, wear resistance and decoration have been significantly improved and enhanced.

Classification of Anodizing Machines

According to the current type, there are direct current anodizing, alternating current anodizing, and pulse current anodizing, which can shorten the production time to reach the required thickness, and the film layer is thick and uniform and dense, and the corrosion resistance is significantly improved.

According to the electrolyte, there are sulfuric acid, oxalic acid, chromic acid, mixed acid and natural colored anodizing with organic sulfonic acid solution.

According to the properties of the film, there are: ordinary film, hard film (thick film), porcelain film, bright modification layer, semiconductor barrier layer and other anodizing.

The application of direct current sulfuric acid anodizing is the most common, because it is suitable for the anodizing treatment of aluminum and most aluminum alloys

Features

◆The film layer is thick, hard and wear-resistant, and better corrosion resistance can be obtained after sealing.

◆The film layer is colorless and transparent, strong adsorption ability and easy to stain;

◆Low processing voltage, less power consumption; 

◆The process does not need to change the voltage cycle, which is conducive to continuous production and practical operation automation;

◆Sulfuric acid is less harmful to the human body than chromic acid, wide supply, low price advantages
