Катодна плоча од алуминијум оксида се разликује од анодизиране алуминијумске плоче, који треба да постави алуминијумску плочу у одговарајући електролит (као што је сумпорна киселина, хромна киселина, оксална киселина, итд.) као катода, и спровести електролизу под одређеним условима и примењеном струјом. Катодне алуминијумске плоче се широко користе у деловима машина, авиона и ауто делова, прецизни инструменти и радио опрема, ...
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 (као што је сумпорна киселина, хромна киселина, оксална киселина, итд.) 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 и 5052 aluminum foil after oxide ...
The hot-rolled 1100 aluminum sheet can be used as the raw materials for anodized aluminum sheet. The anodized aluminum sheet has product applications of interior decoration, household appliances, switch panels, electronic hardware, lighting fixtures, signs, итд. In many series of materials, why does 1100 hot-rolled aluminum sheet be used?Hot rolled 1100 aluminum sheet belongs to the pure 1000 aluminum alloy se ...
