The main cause of corrosion is mainly due to moisture or water in the production process and during the circulation process. Therefore, controlling the generation of corrosive waste is mainly to prevent the aluminum foil from coming into contact with water. Anti-corrosion measures:

1 Strengthen the management of the air dryer to ensure that there is no moisture in the compressed air.

2 Strengthen the management of rolling oil, and its water content is controlled below 400×0.000001.

3 Aluminum foil rolls should be packaged in a sealed package, and an appropriate amount of desiccant should be placed in each roll.

4 The humidity of the wooden shaft and the box board of the package is not more than 18%, and the temperature of the packaged aluminum coil is not more than 45 degrees Celsius.

5 From the low temperature area to the area with high temperature and high humidity, do not open the sealed package immediately.

6 The workshop and warehouse roofs are exposed to rain and snow. Aluminum foil rolls should not be placed.

7 When transporting aluminum foil from a low temperature zone to a high temperature zone, it is necessary to strengthen the sealing of the package and, if necessary, add a desiccant.

8 When packaging aluminum foil products in the rainy season, it is necessary to strengthen the sealed packaging and add desiccant.
