The Main Causes Of Aluminum Foil Corrosion

Mainly during the production and circulation processes, products may become damp or encounter water. Therefore, controlling the generation of corrosive waste is mainly to prevent aluminum foil from coming into contact with water. Anti corrosion measures: ① Strengthen the management of air dryers to ensure that there is no moisture in the compressed air. ② Strengthen the management of rolling oil and control its moisture content at 400 × Below 0.000001. ③ The packaging of aluminum foil rolls should be sealed, and each roll should be filled with an appropriate amount of desiccant The humidity of the wooden shaft and board of the packaging box shall not exceed 18%, and the temperature of the packaging aluminum coil shall not exceed 45 degrees Celsius Do not immediately open the sealed packaging when transporting from a low-temperature area to an area with high temperature and humidity. ⑥ Aluminum foil rolls should not be placed on the roofs of workshops and warehouses where there is rain or snow leakage When transporting aluminum foil from low temperature areas to high temperature areas, it is necessary to strengthen the sealing of the packaging and, if necessary, add desiccants When packaging aluminum foil products during the rainy season, it is necessary to strengthen the sealing packaging and add desiccants.
