The full coloring process of aluminum profiles

[China Aluminum Network] Before the aluminum material is colored, it is necessary to oxidize the aluminum material. When squeezing a good aluminum alloy material, the corrosion resistance of the aluminum material is not strong, and the surface treatment must be performed by anodizing to increase the resistance of the aluminum material. Erosion, wear resistance and appearance of the appearance.
Its main process is:
(1) Surface pretreatment: The surface of the profile is chemically or physically cleaned to expose a pure matrix to facilitate obtaining a complete, dense artificial oxide film. It is also possible to obtain a specular or matt (matte) surface by mechanical means.
(2) Anodizing: After surface pretreatment of the profiles, anodization occurs on the surface of the substrate under certain process conditions to form a dense, porous, strong AL203 film layer.
(3) Sealing: The pores of the pores of the porous oxide film formed after the anodization are closed, so that the oxide film is prevented from contamination, corrosion and abrasion resistance. The oxide film is colorless and transparent. By using the strong adsorption of the oxide film before sealing, some metal salts can be adsorbed and deposited in the film pores, which can make the appearance of the material besides the colors (silver white), such as: black, bronze, Gold and stainless steel and so on.
