The conductive oxidation process of Anodized conductive aluminum tube is easy to operate without special equipment. In recent years, the conductive oxidation film layer is easy to absorb organic coatings, and the understanding of good binding force has been further improved. Therefore, the application range of coating (electrophoresis, painting) substrate has been gradually expanded.
Specific details to be paid attention to in the pretreatment process
Anodized conductive aluminum tube in the air is very unstable, easy to produce with the naked eye also difficult to identify the oxide film.Due to the different method of aluminum processing technology, such as casting molding, or directly by the delay of pressure plate shear, or fine mechanical processing and forming, or approved by different process forming after the heat treatment or welding, the surface will present different status, different degrees of dirt or marks, therefore in pre-treatment process must choose according to the actual situation of the surface pretreatment process method.
Anodizing of aluminum is an electrolytic oxidation process in which the surface of aluminum and aluminum alloys is usually converted into an oxide film that has protective, decorative, and other functional properties.Anodic oxidation of aluminum from this definition only includes the process of producing anodic oxide film.
