彩涂板的氧化问题

随着彩涂板的使用率越来越普遍，其质量也越来越高，由于其自身的特点和优势，得到了广泛的应用。为了更好地利用它，让我们了解氧化问题。
彩涂板在使用中必须防止氧化，因为氧化后很难看清，对用户来说也是一个很大的损失。氧化彩涂板很难使用，但如何防止其在空气中氧化呢？首先，包装要按温湿度进行，所以木轴、板材的湿度不宜大于18%，铝卷的温度不宜大于45℃。如果从低温区进入高温高湿区，请不要立即打开密封包装。为了使冲孔网有时间适应这些环境，冲孔网不应设置在车间、仓库的屋顶有漏雨和积雪的地方。加强空气干燥管理，压缩空气不含水分。加强轧制油的管理，使含水率控制在0.04%以下。彩涂板铝板网采用密封包装，每卷内加入适量干燥剂。减少冲孔网表面与空气和湿气的接触，可以在很大程度上防止铝板冲孔的氧化，对铝板冲孔起到重要的保护作用。

彩涂板采用不锈钢数控冲孔而成。不锈钢特殊材料冲孔时有时会有划痕，影响外观和使用。为了防止这种情况，可以在不锈钢表面涂一层薄薄的塑料膜。覆膜是一种物理过程，即用高温高压将一层薄膜和一层铝板压在一起。层压工艺具有许多优点，不受空气和湿度的氧化，可以减少生产过程中对铝板的损伤。

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.
The color coated plate is made of stainless steel by numerical control punching. Sometimes there are scratches when punching stainless steel special materials, which affect the appearance and use. To prevent this, a thin plastic film can be coated on the surface of stainless steel. Film covering is a kind of physical process, that is, a layer of film and a layer of aluminum plate are pressed together by high temperature and high pressure. The laminating process has many advantages, it is not oxidized by air and humidity, and can reduce the damage to aluminum plate in the production process.
