Embossed aluminum coil is a very common aluminum material in life. The embossed aluminum coil on the market is widely used in the production of refrigerators, air conditioners, lamps, mechanical equipment shells and other products, but there are also some disadvantages, that is, long time and If you do not pay attention to the aluminum protection coil, corrosion will occur.

The reason for the oxidative corrosion of the aluminum coil is that the surface of the aluminum coil is not completely in contact with the air due to the packaging state before use, and the protective layer has not yet formed.In this case, if the aluminum coil enters the water, after being rained or damp, the water in the moisture will chemically react with the surface of the aluminum coil, causing corrosion of the aluminum coil. The situation will turn black and black, as if it had been burned by fire. However, after this corrosion occurs, there will be no secondary damage to the aluminum coil. The aluminum coil itself is no problem, but the appearance is damaged.

How to effectively avoid oxidative corrosion of embossed aluminum coil:

1,Where there are leaks and snow on the roof of workshops and warehouses, aluminum coils should not be placed.

2,Strengthen the management of air drying to ensure that there is no water in the compressed air.

3,The packaging of aluminum foil rolls should be sealed, and an appropriate amount of desiccant should be placed in each roll.

4,When transporting from a low temperature area to an area with high temperature and high humidity, do not open the sealed package immediately.

5,Strengthen the management of rolling oil, and control its water content below 0.04%.

6,The humidity of the wooden shaft and box board of the packing box is not more than 18%, and the temperature of packing the color aluminum coil is not more than 45 ℃.

Oxidation under normal conditions means that after the aluminum coil is used, for example, after being wrapped on a pipe, the surface of the aluminum coil will be completely in contact with the air to form an oxide film, which will protect the aluminum coil from further corrosion, so after use , Even if it is rained again and exposed to the sun, the embossed aluminum coil will not corrode.
