The surface of the
architectural aluminum profiles has been oxidized, and the appearance is very beautiful, and the dirt resistance, once coated with oil is very easy to clean.
Now aluminum alloy material with its small proportion, easy processing, high mechanical strength and other characteristics for many years has been widely used in building doors, windows, curtain walls and other products, architectural aluminum profiles is widely used, aluminum is a silver luster more lively light metal, its corrosion resistance has the following two characteristics:
1. The mechanical strength of aluminum alloy is high, but the corrosion resistance is weak. Although the erosion opposition of pure aluminum is good, but the mechanical intensity is poor, which restricts the application of aluminum to a given degree. Therefore, people add appropriate amount of magnesium, copper, zinc and other metals in aluminum to make various types of aluminum alloy. The mechanical intensity of aluminum alloy is extremely improved, and the range of application is greatly expanded, but the erosion resistance is worse than pure aluminum, so it is probable to be corroded by oxidation.
2. The higher the strength, the better the corrosion resistance, mainly because pure aluminum in the air and oxygen action, the production of a thin layer of dense natural oxide film on the surface of aluminum, faster and thicker than other metal oxide film, and then prevent the further corrosion of oxygen and moisture in the air, played a protective role;
What are several ways of surface treatment for architectural aluminum profiles?
1. Electrophoretic coating
2. Powder spraying
3. Anodize
Customers should choose the surface treatment process according to their actual application needs, because each aluminum alloy surface treatment process has different effects, of course, the price is not the same.
