Product details

Aluminum coil pretreatment is the first step in the production of color coated aluminum coil. Its main function is to clean the surface, remove oxide skin and oil stains, to ensure that the coating can firmly adhere to the surface of the aluminum coil. Aluminum coil pretreatment can be divided into two methods: mechanical cleaning and chemical cleaning. Mechanical cleaning mainly uses mechanical force and water flow to wash the surface of aluminum coils, removing dirt and oxide skin on the surface. Chemical cleaning is the use of chemical methods such as acid or alkali washing to remove surface oxide skin and oil stains. After the pre-treatment of the aluminum coil is completed, it needs to be washed and dried with water to ensure that the surface of the color coat aluminum roll is clean and pollution-free.
