    Update of anodizing pretreatment process [ 12-01 17:20 ]
    The purpose of anodizing pretreatment is to remove natural oxide film, grease and impurities on the surface to obtain uniform and clean aluminum surface, which is conducive to the formation of high-quality anodized film in Dongguan. Chinese users also require to remove the extrusion fringes to obtain a uniform and beautiful surface. In the early stage, alkali etching method was used to obtain matte surface, but excessive etching made aluminum loss very large, generally up to 3% - 5.5%, which not only increased the cost, but also caused serious environmental problems, forming matte surface and exposing the inherent structural defects of the profile. Since then, Japan introduced the acid etching method in China (basically not used for aluminum profiles in Japan). Due to the low aluminum consumption (up to about 1%), the surface fineness was once welcomed by Chinese manufacturers. However, due to the fluoride ion as the main body of the tank liquid, brought more serious pollution
    Core technology of hard oxidation surface treatment and aluminum oxidation processing of Dalang aluminum [ 12-01 17:18 ]
    In order to improve the functional quality of the hard oxide film, some people try to form a kind of film on the surface to improve the hardness of the film. A layer of molybdenum oxide hydroxide film was formed on the surface of the sample before anodizing, and then oxidized by sulfosuccinate sulfuric acid. The hardness of the film was up to 690hv. This effect can also be obtained by passivation, or in the oxidant aqueous solution, after a short period of electrolysis with aluminum as cathode, and then anodized in sulfuric acid solution, the film with high surface hardness and low dynamic friction coefficient can be obtained. a lethal layer is formed on the surface of aluminum by cathodic electrolysis for minutes
