5252 Aluminium Sheet china Oxidized Surface Oxide Layer Formation Principle Explained
09-28
In the air, 5252 Aluminium Sheet china oxidation surface oxidation and oxygen function can produce a layer of air oxide film, but the film is thin (3 × 10-3 ~ 5 × 10-3 μm) and loose porous structure, amorphous, asymmetrical A film that does not last, can not be used as a reliable and reliable protection - decorative art film. At this stage, anodizing treatment or organic chemical corrosion are widely used in industrial production to convert the surface of aluminum and aluminum alloy products into a layer of air oxide film, so as to achieve the purpose of reliable protection-decoration design.
5252 Aluminium Sheet china Oxidation surface oxidation is an air oxide film obtained by catalytic air oxidation. The thickness is generally 0.3~4μm, soft, and its wear resistance and thixotropic properties are smaller than that of the anodized film. The thickness of the air oxide film obtained by anodizing treatment is generally 5~20μm, and the thickness of the hard anodized film can reach 60~250μm. resistance, wear resistance and strength. The air oxide film with porous structure has strong adsorption ability, which is easy to be colored with organic dyes. At the same time, it also has the characteristics of good insulation performance and strong heat insulation and heat resistance.
