The main process of car amplifier fabulous box oxidation:
Surface pretreatment: the surface of the profile is cleaned by chemical or physical methods to expose the pure matrix, so as to obtain a complete and compact artificial oxidation film. Mirror or matte (matt) surfaces can also be obtained mechanically.
Anodizing: after surface pretreatment, the profile is anodized on the surface of the substrate under certain technological conditions to form a dense, porous and strong adsorption Al2O3 film layer.
Sealing: close the pores of the porous oxide film formed after anodic oxidation, so as to enhance the anti-pollution, anti-corrosion and wear resistance of the oxide film. Oxidation film is colorless and transparent, use the strong adsorbability of oxidation film before sealing a hole, a few metal salt are adsorbed inside film hole, can make profile appearance shows natural color (silvery white) a lot of color beyond, be like: black, bronzer, golden yellow reachs stainless steel color to wait.
