对于彩涂卷寿命概念知识讲解以及其作用

根据彩涂板的涂层结构特点和机理，分析了彩涂板的使用寿命。本质上是指在实际应用条件下，彩色涂层耐腐蚀性和有机膜耐候性的有效使用极限的统一体现。如果使用年限的计量标准不统一，使用年限的概念就不可能一致。每种产品的生产之所以能够得到很好的开发和应用可以间接地解释它具有一些特点，并在产品的应用中发挥一定的作用。

The service life of color coated coil is analyzed on the basis of its coating structural characteristics and mechanism. In essence, it refers to the unified embodiment of the effective service limit of color coating corrosion resistance and organic film weather resistance under the actual application conditions. If the measurement standards of service limit are not unified, the concept of service life cannot be consistent. The reason why the production of each product can be well developed and applied can indirectly explain that it has some characteristics and can play some role in the application of the product.

Color coated roll
Today, I will introduce the application of color coated roll products:
Color coating roll is commonly known as polyvinylidene fluoride color coating roll. It has a good application in buildings. The main advantage is that it has good UV protection ability. Color coating roll is made of high-end polyvinylidene fluoride resin. We all know that there is a strong bond energy between chemical bonds of PVDF, Thus, the coating has very good corrosion resistance and color retention. Finally, it belongs to the most advanced product in the color coated steel plate coating for construction industry, with large molecular weight and straight bond structure. In addition to chemical resistance, color coated roll is also well recognized for its mechanical properties, UV resistance and heat resistance.
For the color coating roll, we can choose the most suitable resin according to the different application environment. The application resins we can choose include polyester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, etc. This point can be selected according to the actual needs of users. To sum up, it is not difficult for us to understand the wide application of color coated rolls in construction, household appliances, electromechanical, transportation, interior decoration, office appliances and other industries.
