Many aluminum foil manufacturers often encounter a problem when purchasing
aluminum foil jumbo rolls for product processing, and that is the oxidation of the aluminum foil. The oxidized aluminum foil can no longer be used to make aluminum foil products. As a result, manufacturers often have to remove the outside oxidized part of the aluminum foil rolls, thereby greatly increasing production costs. In this article, we will introduce in detail how to avoid oxidation of aluminum foil.
Production Process:
1. Aluminum foil requires the use of rolling oil during the rolling process, The rolling oil contains a variety of chemical components, Only very experienced factories can accurately control the ratio of rolling oil to avoid oxidation of the aluminum foil to the greatest extent.
2. In the production process of aluminum foil large rolls, the aluminum foil will be made to reach the appropriate thickness through rollers. During this process, friction will occur between the rollers and the surface of the aluminum foil. If not operated properly, roughening will occur on the surface of the aluminum foil, causing the aluminum foil to easily oxidize. Therefore, choosing Excellent manufacturers, and their good workmanship will help reduce the possibility of oxidation of aluminum foil.
Shipping and storage:
1. Temperature changes can easily produce water vapor, which can lead to oxidation of aluminum foil. Therefore, when aluminum foil is transported from a low-temperature area to a place with high temperature and high humidity, do not open the package immediately and give it some time to adapt to the environment.
2. The storage environment has the greatest relationship with whether aluminum foil is oxidized. Humid air can easily cause aluminum foil to oxidize, Therefore, the storage environment of aluminum foil should be ensured to be dry and well-ventilated. In addition, the air in coastal areas has high salt content and is more susceptible to oxidation, so factories in coastal cities should take precautions.
