1. Surface pretreatment: Use chemical or physical methods to clean the surface of the ceramic fiberboard to expose the pure matrix, in order to obtain a complete and dense artificial oxide film. It can also obtain a mirror or matte surface by mechanical means.

2. Anodizing: The aluminum silicate fiberboard with surface pretreatment will be anodized on the surface of the substrate under certain process conditions to form a dense, porous, and strong adsorption AL203 film.

3. Sealing: The pores of the porous oxide film formed after anodization are closed to enhance the anti-pollution, corrosion resistance and wear resistance of the oxide film of the aluminum silicate fiberboard. The oxide film is colorless and transparent, and the hole is sealed. The strong adsorption of the front oxide film can adsorb and deposit some metal salts in the film pores, which can make the appearance of the profile show many colors other than the natural color, such as: black, bronze, golden and stainless steel.
