Aluminum alloy doors and windows surface oxidation how to deal with?
The chemical nature of the aluminum element itself is very lively
However, the aluminum alloy surface will form a layer of dense aluminum oxide film
Thereby preventing the internal aluminum from being continuously oxidized
The surface oxidation of the aluminum alloy is for the thickening of the aluminum oxide film
Enhance the corrosion resistance and abrasion resistance of aluminum alloy products.
If you have found aluminum alloy doors and windows have been the phenomenon of oxidation and rust, you can use the fiber brush with the rust to the rust brush can go.
Be careful not to use grit, sandpaper, wire balls and other polished. Aluminum alloy doors and windows surface rust is removed, the exposed aluminum and oxygen in the air oxidation reaction, resulting in a new layer of protective film. The use of sandpaper, wire ball will destroy the original aluminum oxide protective film, resulting in a new aluminum alloy oxidation reaction, aluminum alloy doors and windows will become increasingly thin, and ultimately affect the life of aluminum doors and windows. It is not you on the unified doors and windows for the new good, and now the price of aluminum is not very expensive, and the new Hao Xuan doors and windows have energy-saving insulation broken bridge profiles, processing doors and windows are both energy saving and environmental protection!
