Anodized aluminium strip is a kind of aluminum strip product that processed by anodising progress. Because the surface corrosion resistance of the extruded aluminum alloy raw materials is not strong, we must carry out surface treatment by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum material. The main process of oxidation of aluminum strip is surface pretreatment, anodizing and sealing. And Haomei Aluminum is a professional aluminum strip product manufacturer and supplier in China, which provides aluminum strips for sale. And today we are going to introduce the oxidization condition of aluminum strip products made by Haomei Aluminum.
Surface pretreatment is to clean the surface of aluminum strip products by chemical or physical methods, exposing the pure substrate, in order to obtain a complete and dense artificial oxide film. We can also obtain mirror or matte surfaces by mechanical means. Next, the aluminium strip can be anodized. The surface pretreated aluminum product, under certain process conditions, undergoes anodization on the surface of the substrate to form a dense, porous, and strong Al2O3 film layer. Next we need to seal the hole. The pores of the porous oxide film formed after anodization are closed, so that the anti-fouling, corrosion resistance and wear resistance properties of the oxide film are enhanced. The oxide film is colorless and transparent. Using the strong adsorption of the oxide film before sealing, some metal salts are adsorbed and deposited in the film pores, which can make the appearance of aluminum strips, show many colors other than the original color (silver white). Such as: black, bronze, golden and stainless steel.
The anodized aluminium strip provided by Haomei Aluminum have been favoured by our customers, and they repurchase again and again, we know the quality assurance and great price are the obvious advantages and we are willing to contain these advantages for long tern cooperation.
