How to prevent aluminum coil oxidation Mingtai Aluminum

Edit:Mingtai Date: 2019-06-03 15:48
When the aluminum coil is placed for a long time, the surface will be oxidized and appear white spotted. After cleaning, it will become dark spots and affect the use. Is there a better and convenient preservation method?
Under normal circumstances, aluminum itself is resistant to oxidation. The above phenomenon indicates that the warehouse is very wet, and other acidic substances destroy the dense aluminum oxide protective film. However, the aluminum coil is not convenient for painting.
Remind you to prevent oxidation of aluminum coils:
(1) It is effective to wrap it with a plastic film, and it is preferable to put a desiccant such as silicon inside.
(2) The humidity of the wooden shaft and the box board of the package is not more than 18%, and the temperature of the packaged color aluminum coil is not more than 45 °C.
(3) When transporting from a low temperature area to a place with high temperature and high humidity, do not open the sealed package immediately.
(4) Where there is rain or snow on the roof of the workshop and warehouse, color aluminum coils should not be placed.
