1, profile selection, duralumin bar: Before the process of processing aluminum products profiles, raw materials should be selected duralumin products profiles, and the mounting equipment used in the production process should be kept conductive and smooth.
2, small specifications, special treatment: For small specifications of lap riveted aluminum components, generally do not use sulfuric acid anodizing treatment.
3, in the production process, conductive area: in the production process of anodized aluminum 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 sulfuric acid anodizing solution temperature range is generally 15~25℃.
5, refrigeration device, compressed air mixing: anodized aluminum production and processing process should be equipped with refrigeration device, using compressed air mixing treatment method to carry out.
6. Clean up the equipment before aluminum oxidation: clean up the previously used equipment before anodizing the aluminum profiles. Remove the residual oxide film on the surface of the equipment to ensure good contact performance with the aluminum rod in use.
