Aluminum inventory of the company, placed for a little longer, there will be surface oxidation, white spot shape, after cleaning into black spots, affecting the use of. Is there a better and convenient way to save it?
Aluminum coil formation prevents oxidation of aluminum coils.In the aluminum coil chemical treatment to prevent oxidation of the surface of the aluminum layer to prevent corrosion, and increase after coating adhesion and corrosion resistance of the coating, conversion layer appearance color, golden yellow or green blue, the main function in ensuring the consistency of coating and film combination.
In general, aluminum itself. You said that the antioxidant warehouse is wet, there are other acidic substances damage the alumina compact protection film. Aluminum volume convenient paint, or wrapped in a plastic film, the best conditions inside the silicon desiccant
1. aluminum storage environment should be dry and bright, well ventilated, no corrosion climate.2. aluminum coil should try to avoid the leaks, snow.3. strengthen the management of rolling oil, its moisture content is controlled below zero point zero four percent.4. aluminum rolls should be packed in a sealed package and should be placed in the right amount of desiccant at the same time.5. do not immediately open the sealed package when it is transported from a low temperature zone into a region of high temperature and humidity.6. the humidity of the wooden shaft and box board of the packing box is not more than 18%, and the temperature of the color aluminum roll is not more than 45 degrees.7. aluminum rolls are prohibited from being stored with chemicals and moist materials during storage.
