Five Advantages of Aluminum Anodizing Manufacturers' Products Introduction
1. Bottom layer for spray painting and electroplating: Due to the porous nature and good adsorption ability of the oxide film layer, it has good adhesion with paint film and organic film, and can be used as the bottom layer for spray painting. The film anodized by Aluminium phosphate can be used as the bottom layer for electroplating on aluminum.
2. Prevention of product corrosion: Due to the appropriate sealing treatment of the film layer obtained from aluminum anodizing, it has good stability in the atmosphere. Whether obtained from sulfuric acid solution, anodized acid solution, or polishing acid solution in normal processes, the aluminum anodized film has excellent corrosion resistance.
3. Protection and decoration: On the surface of an oxide film with high transparency, the oxide film has the characteristic of adsorbing various organic or inorganic pigments. Various bright and bright colors and patterns can be obtained on the oxide film. In addition, in recent years, many new technologies have emerged, such as multiple coloring in one oxidation, fireworks patterns, wood grain patterns, oxidation offset transfer printing, porcelain oxidation, etc., making the appearance of aluminum more beautiful and pleasing to the eye, This colored film is both a decorative layer and an anti-corrosion layer, such as lighters, gold pens, and handicrafts.
4. As a hard wear-resistant layer: In sulfuric acid or anodize acid solutions, thick and hard film layers can be obtained by adjusting the process conditions of anodizing. The pores and absorption properties of the film layer are used to store selected oil materials, effectively applied to working conditions under friction, and have lubrication and wear resistance characteristics, such as engine cylinders, pistons, etc. of automobiles and tractors.
5. As an insulation layer for electricity: Aluminum anodized film has the characteristic of high resistance, and the thickness of the film is proportional to the resistance. This feature has practical significance as an insulation layer for electricity, and can be used as a dielectric for capacitors or as an outer sheath for cables. Aluminum oxide skin can be used as an insulation layer on its surface to replace rubber and plastic sheaths, which is relatively popular abroad. The film thickness is 27.5 μ At m, its breakdown voltage is 441V. If phenolic resin is used as a filler for membrane pores, its breakdown voltage can be increased by two times. In anodizing acid solution, when the film thickness increases, a high-quality insulation layer with a resistance of 200 Ω and a breakdown voltage of 980V can be obtained. Of course, this feature can be used not only for wires, but also for other electrical appliances and other aspects.
