How to Prevent Oxidation of Aluminum Coil For Sale
Before using, the surface of the aluminum coil for sale is not completely in contact with the air and the protective layer has not been formed due to the packaging. In this case, if the aluminum coil is exposed to rain or moisture, the moisture will chemically react with the surface of the aluminum coil to make it corrode.
The corroded aluminum coil will show corrosion marks, and the sever result is even causing the aluminum coil stock become black, just like it has been burned. However, after this corrosion occurs, the secondary damage of the aluminum coil will no longer appear, and the aluminum coil itself is not problematic, but the appearance is damaged.
How to avoid the oxidation of the aluminium coil stock for sale? There are some tips.
1. The aluminum coil stock should not be placed in the warehouse where there is rain or snow leakage.
2. The sealed packaging should be used for the aluminum coil, and an appropriate amount of desiccant should be put in each roll.
3. When transporting from a low temperature area into an area with high temperature and high humidity, do not open the sealed package immediately.
4. Strengthen the management of rolling oil, and control its water content below 0.04%.
5. The humidity of the wooden shaft and the wooden box is not more than 18% and the packaging temperature is not more than 45 ℃.
Normal oxidation means that after the aluminum coil is used, for example, when it is wrapped in a pipe, the surface of the aluminum coil will completely touch the air and form an oxide film. This oxide film will protect the aluminum coil from further corrosion. As an experienced aluminum coil provider facing to the global market, we can ensure the aluminum coil quality when it reaches the destination.
