Aluminum anodic oxidation treatment 6 main points

1. Profile selection, duralumin bar: Before processing aluminum profiles, raw materials should be selected duralumin profiles, and the mounting equipment used in the production and processing process should be kept conductive and unobstructed.

2, small size, special treatment: for small size lap riveted aluminum components, generally do not use sulfuric acid anodic oxidation treatment.

3, in the production process, conductive area: in the production process of anodic alumina products profiles, the conductive contact area of the equipment should be ensured, and the imprint of the equipment should be as little as possible.

4, oxidation solution, temperature range: anodized alumina used in sulfuric acid anodizing solution temperature range is generally 15~25℃.

5, refrigeration device, compressed air stirring: the production and processing of anodic alumina should be equipped with refrigeration device, using the compressed air stirring treatment method to carry out.

6. Clean up the equipment before oxidation of aluminum: clean up the previously used equipment before anodic oxidation of aluminum profiles. Remove the residual oxide film on the surface of the equipment to ensure good contact performance with the aluminum rod in use.
