How to clean the aluminum coil in the production process of marble aluminum composite panel?
There are several methods and process technologies to produce the marble aluminum composite panel
. According to the composite process of the plastic core board and the aluminum board on both sides, the process can be divided into cold and hot compound method; It can also be divided into continuous compound method and intermittent compound method.
In the production process of marble aluminum plastic composite panel
, the most important step is cleaning aluminum coil. The surface of the aluminum rolling material is coated with lubricants and antioxidants for the technology requirements, and in the transport its surface will also adhere to some dirt, which will affect its adhesion, so it must be cleaned. After cleaning and chemical treatment, a layer of dense chemical protective film will be produced on the surface of aluminum rolling material. This layer of chemical film can improve the oxidation resistance of aluminum roll and prolong the life of paint film. The general process of cleaning is as follows: aluminum coil, spray degreasing, washing, neutralization, chemical treatment, washing, drying, cooling, winding. The cleaned aluminum coil is sent into the coating machine and the outer surface of the aluminum coil is coated with high performance fluorocarbon resin.
