The advantages of color-coated coils such as light weight, beautiful appearance and good anti-corrosion performance are gradually known by people. Due to their wide application and superior product performance, they have become the products that everyone is rushing to buy. The market has broad prospects for development, and the production technology has been constantly improving. But we still need to pay attention to some special operation methods. Today, our editor will tell you what to pay attention to in the process of cold-rolling color-coated coils. Let’s take a look.
Color-coated coils are generally in the process of cold rolling, due to the collision and rolling between the roller and the surface of the aluminum plate, the surface will produce fine oxide powder fall off and adsorption, rolling oil and accompanying suspended components will remain on the aluminum plate, and the color-coated coil will be affected. The processing of finished products such as compounding and painting will cause unfavorable effects. At this time, it needs to be cleaned by special cleaning equipment. The cleaning method is mainly to pressurize the cleaning medium through a pressure pump, and perform non-contact brushing on the surface of the color-coated roll, so that the aluminum powder oil on the plate surface can be dissolved and fallen off. Then, it is squeezed dry by a squeeze roller, blown by high pressure air, and even dried by high temperature air, so as to obtain a clean and smooth color-coated coil.
