The process of using an aluminum plate as an anode to form an aluminum oxide film on the surface through electrolysis in an electrolyte solution is called anodizing of the aluminum plate. The cathode in the device is a material with high chemical stability in the electrolyte, such as lead, stainless steel, aluminum, etc. The principle of aluminum anodization is essentially the principle of water electrolysis. When current passes, hydrogen is released at the cathode. On the anode, the evolved oxygen is not only molecular oxygen, but also atomic oxygen (0) and ionic oxygen, which are usually expressed as molecular oxygen in the reaction. The aluminum used as the anode is oxidized by the oxygen deposited on it, forming an anhydrous aluminum oxide film, and not all of the oxygen produced acts on the aluminum.
Aluminum corrugated panels, also known as corrugated aluminum panels, pressed aluminum panels, aluminum tiles, etc., are pressed panels made of aluminum sheets pressed into various corrugated shapes. They are suitable for industry, civil buildings, warehouses, special buildings, and large spans. The roofs, walls and interior and exterior wall decorations of steel structure houses have the characteristics of light weight, high strength, rich colors, convenient and quick construction, earthquake resistance, fire protection, long rainproof life, and maintenance-free. They have been widely used.
