Hoe maak je aluminiumfolie goud??
1) Voorbehandeling van het oppervlak: reinig het profieloppervlak door chemische of fysische methode, leg de zuivere matrix bloot, om een volledige en dichte kunstmatige oxidefilm te verkrijgen. Spiegelend of mat (mat) oppervlakken kunnen ook mechanisch worden verkregen.
2) Anodische oxidatie: Voor de oppervlaktevoorbehandelde profielen, 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.
De oxidefilm is kleurloos en transparant. 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, bronzen, gold and stainless steel.
