With the use rate of color coated board becoming more and more common, its quality is also getting higher and higher, because of its characteristics and advantages, it is widely used by everyone. In order to make better use of it, let's understand the oxidation problems.Color coated board must be protected from oxidation in use, because it is hard to see after oxidation, and it is also a big loss to users. Oxidized color coated board can hardly be used, but how to prevent it from oxidation in the air? First of all, the packaging should be carried out in terms of temperature and humidity, so the humidity of wood shaft, plate should not be greater than 18%, and the temperature of aluminum coil should not be greater than 45 ℃. If you enter the high temperature and humidity area from the low temperature area, please do not open the sealing package immediately. In order to make the punching net have time to adapt to these environments, the punching net should not be set in the roof of workshop and warehouse where there is rain leakage and snow. Strengthen air drying management, compressed air does not contain moisture. Strengthen the management of rolling oil to keep the moisture content below 0.04%. The aluminum sheet mesh shall be packed in a sealed package, and an appropriate amount of desiccant shall be put into each roll. Reducing the contact between the surface of punching net and air and moisture can prevent the oxidation of aluminum plate punching to a great extent, which plays an important role in protecting aluminum plate punching.
