2A12 Aluminum plate  needs to be anodized before use, and can be dyed after anodizing. The coloring process is mainly divided into organic dyeing, inorganic dyeing, electrolytic coloring and electroplating coloring. Today, xiaobian will introduce to you the organic dyeing process of  2A12 aluminum plate.

The organic dye is adsorbed on the theoretical basis of substances, physical adsorption and adsorption point of chemical adsorption, physical adsorption on the electrostatic adsorption of molecules or ions;Chemisorption, chemisorption mode, the combination of the two to produce an organic dye, which is usually carried out at a constant temperature.Organic chemical dyeing color fast, bright color, simple and convenient operating system, through the hole sealing treatment after dyeing, the dye can firmly adhere to the membrane pores, improve the anticorrosive ability of the film, fight corrupt ability, until the students can keep at the same time a beautiful color, suitable for outdoor activities for for those companies do not need to use a large number of 2 a12 aluminum commodity, indoor use aluminum industrial products market and other decorations and so on, colorful and varied appearance design.

1.The oxide film should have sufficient porosity

2.The inner wall of the membrane pore maintains some activity

3.More suitable for dyeing is in sulfuric acid solution, mainly after its anodic oxidation, anodic oxidation film colorless and porous.

4.2 how thin the oxide film layer of A12 aluminum plate is, the dyeing will be very shallow, so it is necessary to have a certain thickness of oxide film.

5.Not suitable for organic staining is the hard anodic oxide film with chromic acid conventional oxide film layer.

6.The oxide film layer should be kept intact, uniform and free from scratches and other defects.

The above is the organic dyeing process of 2A12 aluminum plate. If you need 2A12 aluminum plate, please contact us.
