Introduction and Advantages of Anodized Aluminum Plate
Chemical oxidation of aluminum plate is aluminum plate in weakly alkaline or weak acid solution, part of the matrix metal reaction, make its natural oxide film on the surface of the thickening or produce other passivation membrane process, the commonly used chemical oxidation film with phosphoric acid and chromic acid membranes, they do thin adsorption, nice, coloring and sealing hole processing can be performed.
Introduction of anodized aluminum plate
Anodized aluminum plate is used as an anode in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid etc.) and electrolysis under certain conditions and external current.The aluminum plate of the anode is oxidized and the thin layer of alumina is formed on the surface. The thickness of the anode is 5 ~ 20 micrometers. The oxide film of hard anodic can reach 60 ~ 200 microns.After the anodic oxidation of aluminum plate, improves the hardness and wear resistance, can reach 250 ~ 500 kg per square millimeter, good heat resistance, hard anodic oxidation film melting point as high as 2320 k, excellent insulation, resistance to breakdown voltage of 2000 v, to enhance the corrosion resistance, hitches in omega = 0.03 NaCl salt fog corrosion thousands of hours.The thin layer of oxide film has a large number of micropores, which can absorb various kinds of lubricants, suitable for making engine cylinder or other wear-resisting parts.The film microporous adsorption ability can be colored into various beautiful and colorful colors.Non-ferrous metals or their alloys (such as aluminum, magnesium and their alloys) can be treated with anodic oxidation.
Advantages of anodized aluminum plate :
(1) good workability, high oxidation aluminium plate, adornment sex is strong, moderate hardness, can be easily bending forming, continuity high-speed stamping, convenient and directly processed into products, surface treatment need not be complicated, greatly shorten the product production cycle and reduce the production cost.
(2) good weatherability: the standard thickness oxide film (3 mu m) of anodized aluminum plate is used for a long time without discoloration, corrosion, oxidation and rust.The anodized aluminum plate of the thickened oxide film (10 mu m) can be used outside, but it can be exposed to the sunlight for a long time.
(3) strong metal feeling: the anodization of aluminum plate surface hardness, grade gems, good scratch resistance, surface paint coverage, keep aluminum sheet metal color, highlight modern metal feeling, improve the product grade and added value.
(4) fire-proof height: pure metal products, without paint and any chemical substances, 600 degrees of high temperature do not burn, produce no poisonous gas, meet fire protection environmental requirements.
(5) strong anti-fouling: leave no fingerprints, no stain marks, easy to clean, no corrosion spots. 【Anodized aluminum plate】
(6) strong applicability: widely used, suitable for metal aluminum ceiling, curtain wall panel, aluminum plastic plate, fire prevention plate, honeycomb aluminum plate, aluminum veneer, electrical plate, cabinet plate, furniture plate, etc.
