The service life of color coated roll is analyzed on the basis of its coating structure characteristics and mechanism. In essence, it refers to the unified embodiment of the effective service limit of color coating corrosion resistance and organic film weathering resistance under the actual application conditions. If the standard of service limit is not unified, the concept of service life can not be consistent. The reason why the production of each product can get a good development and application can indirectly explain that it has some characteristics and can play a certain role in the application of the product. Today, we introduce the application of color coated roll productsColor coating roll is commonly known as polyvinylidene fluoride (PVDF) color coating roll. It has a good application in architecture. The main advantage is that it has good anti ultraviolet ability. The color coating roll is made of high-end polyvinylidene fluoride resin. We all know that there is a strong bond energy between the chemical bond and the chemical bond of PVDF, so that the coating has a very good performance Finally, it belongs to the most advanced product in the color coated steel plate coatings for construction industry, with large molecular weight and straight bond structure. In addition to chemical resistance, the mechanical properties, UV resistance and heat resistance of color coated roll are also well recognized. For the color coated roll, we can choose the most suitable resin according to the different use environment. The application resins we can choose include: Polyester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, etc. Users can choose according to their actual needs.
