Depending on the metal elements containing aluminum, aluminum can be divided into nine categories, that is, can be divided into nine series, following a step by step outline the 1000 Series II, 2000 series aluminum three 3000 series aluminum representatives for 3003 3003 3A21 the Lord. Also known as rust-proof aluminum of 3000 series aluminum production process is more outstanding. 3000 series aluminum is made of manganese as the main ingredient. Content between 1.0-1.5. . 1, pre-treatment, first using the method of surface cleaning, using physical and chemical methods can be digitally foil suppliers, the most important is the aluminum coil is exposed substrate. Thus is carried out in favor of the complete oxidation of electronic aluminum foil manufacturers oxide film formed will be dense. pretreatment can also use some mechanical handling equipment. 2. anodized aluminum coil after after treatment, the matrix anodic oxidation electronic aluminum foil, then that will generate dense oxide film. 3. plugging, after anodizing electronic foil manufacturers, will appear on the oxide film a lot of film hole, sealing the hole is to make these films closed to prevent contamination of the oxide film. This oxide film is transparent, and is an adsorption, so some salt will be deposited in the hole, so that we can reveal the appearance of some original silver-white, many colors or spot outside the electronic aluminum foil manufacturers |. electronic aluminum foil | aluminum rolls by Jinan Heshun Aluminium Limited.
