Alumina plate: the aluminum in the appropriate electrolyte solution (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, under certain conditions and impressed current role, be formed of aluminum electrolysis. Anodic aluminum oxide, forming a thin layer of aluminum oxide on the surface, the thickness of 5 to 20 microns molds for aluminum factory in Jinan, hard anodic oxide films of up to 60 to 200 microns. PS aluminum (also known as print advertising aluminum zinc plate, newspaper board): the thickness of the back of a printed pattern 03 025 or aluminum material. 1, pre-treatment, first using the method of surface cleaning, using physical and chemical methods are the most important is the aluminum coil is exposed substrate. Thus, it helps complete mold for aluminum oxide is carried out, the oxide film formed will be dense. preconditioning can also use some of the machinery and equipment handling. 2. anodized aluminum after processing through the coil, the matrix anodic oxidation occurs, then that will generate a dense oxide film. 3. Sealing , after anodizing, there will be a lot of film on the oxide film hole, sealing the hole is to make these films are closed to prevent contamination of the oxide film. This oxide film is transparent molds for aluminum factory in Shandong, but with adsorption a lot of color so some salt will be deposited in the hole, so that we can reveal the appearance of some of the original silver, or outside the mold for aluminum manufacturer Alcoa _ _ rolls of aluminum molds for aluminum rolls from Jinan Limited. Jinan Heshun Aluminum Co. (www.jnhsly.com) Shandong Jinan, aluminum products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Aluminum leadership in cis with the staff warmly welcome all inquiries negotiations to create a better future for aluminum rolls.
