1. Surface pretreatment: clean the surface of ceramic fiberboard by chemical or physical methods to expose the pure matrix, so as to obtain a complete and dense artificial oxide film. It can also obtain mirror or matte surface by mechanical means.
2. Anodizing: under certain process conditions, anodizing occurs on the substrate surface of aluminum silicate fiberboard pretreated on the surface to form a dense, porous and strong adsorption Al203 film.
3. Hole sealing: seal the pores of the porous oxide film generated after anodizing, so as to enhance the anti pollution, anti-corrosion and wear resistance of the oxide film of aluminum silicate fiberboard. The oxide film is colorless and transparent. By using the strong adsorption of the oxide film before hole sealing, some gold salts are adsorbed and deposited in the film holes, which can make the appearance of the profile show many colors other than the natural color, such as black, bronze Golden yellow and stainless steel, etc.
