The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface with a thickness of 5 to 20 microns, and the hard anodized film can reach 60 to 200 microns. The anodized aluminum plate improves its hardness and wear resistance, up to 250-500 kg/mm2, has very good heat resistance, the hard anodized film has a melting point of up to 2320K, excellent insulation, and breakdown ...
Method 1: mirror anodized aluminum sheet, after ripping off the protective film, touching the mirror with your fingers, the sweat stains on your fingers will stay on top of the mirror, but after scrubbing with a dry cloth or paper towel, fingerprints will be wiped clean and will not leave any trace. Not after the oxidation of the mirror aluminum plate is not the same, leaving the fingerprints will be more and ...
Introduction of anodized aluminum sheet Anodized aluminum sheet is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, under the specific conditions and the effect of external current, electrolysis. The anodized aluminum plate forms a thin layer of alumina on its surface, with a thickness of 5-20 μ M. the hard anodized film can reach 60-200 μ M. After ...
The shocking statistics released by the National Center for Cardiovascular Diseases suggest that China has the highest occurrence of sudden cardiac deaths (SCD) in the world, accounting for over 544,000 deaths annually. That is to say, SCDs occur at a rate of 1,500 people/day or one person/minute in China. According to David Jin, general manager of Henan Huawei Aluminum Co., Ltd. (“Huawei Aluminum”), in view of t ...
Do you know the advantages of anodized aluminum plate sheet?Henan huawei Aluminum anodized aluminum plate hardness is relatively high, good scratch resistance, paint-free surface, anti-fouling effect is very good. Metallic aluminum ceiling, Curtain wall aluminum, as well as fire board, cellular aluminum, aluminum veneer is made of anodized aluminum plate for processing products Anodized aluminum plate wider ra ...
Surface pretreatment
No matter what method is used to process aluminum materials and products, there will be dirt and defects on the surface to varying degrees, such as dust, metal oxides (natural or aluminum oxide films formed at high temperatures), residual oil, asphalt marks, artificial Carrying mudra (the main components are fatty acids and nitrogenous
1. Oxalic acid anodizing
Most of the factors that affe ...
Cathodic aluminum oxide plate is different from anodized aluminum plate, which is to place the aluminum plate in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the cathode, and conduct electrolysis under specific conditions and applied current. Cathode aluminum plates are widely used in machinery parts, aircraft and auto parts, precision instruments and radio equipment, ...
