The color-coated board must be anti-oxidation in use, because it is ugly after oxidation at this time, and it is also a great loss to the user. Oxidized color coated board is almost unusable, but how to prevent it from being oxidized in the air? First of all, the packing should be done according to the temperature and humidity, so the humidity of packing the wooden shaft and board should not be more than 18%, and the temperature in the aluminum coil should not be more than 45%. If you enter a high temperature and high humidity area from a low temperature area, please do not open the sealed package immediately. In order to adapt the perforated mesh to these environments in time, the perforated mesh should not be set in the places where the roof of workshops and warehouses leaks or snows. Strengthen air-drying management, compressed air does not contain moisture. Strengthen the management of rolling oil to keep the water content below 0.04%. The aluminum mesh packaging should be sealed, and an appropriate amount of desiccant should be placed in each roll. Reducing the contact between the surface of the punching mesh and the air and moisture can largely prevent the oxidation of the punching of the aluminum plate, which plays an important role in protecting the punching of the aluminum plate.
The color-coated sheet is made of stainless steel stamping and CNC stamping. In stainless steel, scratches sometimes appear when stamping special materials, which affects the appearance and use. To prevent this from happening, a thin plastic film can be applied to the surface of the stainless steel film. Film covering is a physical process, that is, a layer of film and a layer of aluminum plate are extruded under high temperature and high pressure. The coating process has many advantages, it will not be oxidized by air and humidity, and it also reduces the damage to the aluminum sheet during the production process.
The above is about the oxidation of color-coated boards. I hope everyone can understand that in the process of use, according to the correct operation method, good results can be achieved. If you don’t know, you can call to ask. We will give you reasonable suggestions according to your actual requirements to avoid unnecessary troubles caused by blind operation.
