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, dll.) 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, ...
Advantages of anodized aluminum plate Good processability: the anodized aluminum plate has strong decoration and moderate hardness. It can be easily bent and shaped. It can carry out continuous high-speed stamping. It is convenient to directly process into products without complex surface treatment, greatly reducing production cycle and production cost. A kind of
Good weather resistance: the anodized alum ...
Introduction of anodized aluminum sheet Anodized aluminum sheet is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, dll.) 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 ...
Anodized treatment can make the gloss of the metal surface remain unchanged for a long time, improve the corrosion resistance and mechanical strength, and obtain a decorative appearance after dyeing. Anodized finish aluminum sheet is used in many places. Here are a few examples. Prevent product corrosion: The film layer obtained by the oxidation of the positive electrode has been properly sealed and has g ...
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 ...
In high-rise buildings, we can sometimes see the color white curtain wall aluminum plate, obviously different from the surrounding color, very affect the appearance. It can be seen that not all aluminum sheet is suitable for anodizing processing, hot-rolled aluminum plates are more suitable for anodizing processing base material. Some enterprises in the use of our aluminum sheet products after processing m ...
The cold rolled aluminum coil for anodizing use raw material of cold rolled aluminum coil, then through anodizing, we got the end product-anodized aluminum coil. There are several aluminum alloy can be anodizing. 1060 aluminum coil can be oxidized processing for not very high requirements, after oxidation, the surface is easy to appear color difference, so the cost is low. 1050 dan 5052 aluminum foil after oxide ...
