Cum faci folie de aluminiu de aur?
1) Pretratarea suprafeței: curățați suprafața profilului prin metodă chimică sau fizică, expune matricea pură, pentru a se obţine un film de oxid artificial complet şi dens. Specular sau mat (mat) suprafetele pot fi obtinute si mecanic.
2) Oxidare anodica: Pentru profilele pretratate de suprafață, under certain technological conditions, the substrate surface will be anodized to form a dense, porous and strongly adsorbed Al203 film.
3) Hole sealing: seal the pores of the porous oxide film formed after anodic oxidation to enhance the anti-pollution and anti-corrosion wear resistance of the oxide film.
Filmul de oxid este incolor și transparent. Using the strong adsorption of the oxide film before sealing the hole, some metal salts are adsorbed and deposited in the film hole, giving the appearance of the outline a variety of colors in addition to the natural color (silvery white), such as black, bronz, gold and stainless steel.
