Aluminum profiles extrusion is not easy to rust, which does not mean that it is not easy to rust. If the wrong operation or the aluminum profile itself fails to pass the test, it will also cause rust. The wrong operation is mainly manifested in cleaning with strong oxidant detergent or in a long-term wet and cold natural environment; the failure of the aluminum profile itself is mainly manifested in the unqualified thickness of the air oxide film or the gap on the surface of the aluminum profile. So if there is rust, should it be replaced immediately?
The key to removing rust with caustic soda solution is to remove it in an alkaline chemical solution. It can be determined according to the type of raw materials and the surface condition of the product workpiece extrusion of aluminum profiles. When the oil stain on the surface of the product workpiece is very small, the oil removal and film removal can be solved together. If the oil stain on the surface is very thick, the oil should be removed first, and then the air oxide film should be removed. Otherwise, the oil removal and film removal will be incomplete, which will endanger the development of the subsequent process and will reduce the quality of the surface treatment.
