Coloring process of aluminum shell of 6LR61 battery

Aluminum shell of 6LR61 battery generally uses 3003 aluminum alloy as an important material, because the aluminum shell of 6LR61 battery made of this material has the characteristics of explosion-proof, high temperature resistance and corrosion resistance. The production process of aluminum shell of 6LR61 battery generally needs color treatment, but many people do not understand the process of color treatment. The following technicians from Asia Continent will explain the color treatment process of aluminum shell of 6LR61 battery to you:

Step 1: Surface pretreatment

The aluminum surface of 6LR61 battery is cleaned by chemical or physical methods to expose the pure matrix, so as to obtain a complete and dense artificial oxide film, and a mirror or matte surface can also be obtained by mechanical methods.

Step 2: Anodizing

Under certain process conditions, the aluminum shell of 6LR61 battery with surface pretreatment is anodized on the surface of the matrix to form a dense and porous strong adsorption layer AL203.

Step 3: Sealing holes

The membrane pores of the porous oxide film after anodization are closed, which improves the anti-pollution, corrosion resistance and wear resistance of the oxide film. The oxide film is colorless and transparent. Before using the strong adsorption oxide film to seal the pores, the metal salt is adsorbed and deposited in the membrane pores, which can make the appearance of the 6LR61 battery aluminum shell appear natural color (silver white), such as: black, copper, gold and stainless steel colors.

The process of coloring the battery aluminum shell ends here. The aluminum shell battery is colored, and the main purpose is to make the surface of the aluminum shell a mirror, the appearance is more beautiful, and the coloring of the power battery aluminum shell will not fade. We have discussed the surface treatment technology of the 6LR61 battery aluminum shell, and you can understand it together.
