Ceramic fiber board is widely used in many fields for insulation due to its excellent performance. Therefore, when processing sheet metal, it is necessary to undergo a certain degree of oxidation to improve the product performance of the sheet metal. So, what is the specific method for oxidation of the board? Let me explain in detail below.
1. Surface pretreatment: Chemical or physical methods are used to clean the surface of ceramic fiber boards. The pure substrate is used to obtain a complete and dense artificial oxide film, and a mirror or matte surface can also be obtained through mechanical means.
2. Anodizing: Under certain process conditions, the surface of the pre treated ceramic fiber board will undergo anodizing on the substrate surface, forming a dense, porous, and sturdy AL203 film layer.
3. Sealing: Seal the pores of the porous oxide film formed after anodizing, making the oxide film of ceramic fiber board have enhanced anti fouling, corrosion resistance, and wear resistance. The oxide film is colorless and transparent. The strong adsorption of thin films, i.e. the adsorption and deposition of certain metal salts in the pores of the film, can cause the profile surface to display various colors beyond the original color, such as black, bronze, gold, and stainless steel.
Therefore, through the introduction of the above content, I believe everyone has a certain understanding of the oxidation treatment of ceramic fiber boards. Therefore, whether manufacturers or purchasers, when conducting ceramic fiber board oxidation treatment, they must carry out it correctly to further improve product performance rather than damage it.
