由于彩涂板不仅具有优良的抗氧化、抗腐蚀等特性，而且颜色更加丰富多彩，传统的镀锌板管道防腐已逐渐被彩板所取代。管道保温防腐彩板选用建议采用锌层不低于80克/平米，正面涂层厚度不低于20um的普通PE聚酯彩板。对于野外的石油、天然气输送管道，考虑到管道所处的特殊环境，建议采用PVDF氟碳彩板、佛山万庆高性能聚酯彩板或HDP高耐候彩板。氟碳涂层板是使用氟碳树脂（PVF、PVDF、FEVE等）的氟碳涂料涂装在金属板上，再经高温烘烤做成的金属烤漆涂层板。PVDF氟碳涂层为现有建筑涂层中的极品，为公认的具有保护作用的有机涂层，能保证金属建筑板几十年不受损害并始终保持美丽的颜色。PVDF氟碳涂层在世界各地的建筑物经历了30多年的日晒风吹雨打，始终保持颜色靓丽。PVDF为聚偏二氟乙烯。氟原子最大的电负性能形成十分稳固的氟碳键，加上其分子独特等对称性，使PVDF具有超常的稳定性，独特的抗紫外光光解性能及优异的绝缘性能和机械性能。
Because the color coating plate not only has excellent antioxidant, corrosion resistance and other characteristics, but also more colorful color, the traditional galvanized plate pipeline anticorrosion has been gradually replaced by the color plate.Ordinary PE polyester color plate with zinc layer not less than 80 g / square meter and not less than front coating thickness not less than 20um is recommended.For the oil and natural gas transmission pipelines in the field, considering the special environment of the pipeline, it is recommended to adopt PVDF fluorocarbon color plate, Foshan Wanqing high-performance polyester color plate or HDP high-weather resistance color plate.Fluorocarbon coated plate is a metal paint coating plate made of fluorocarbon resin (PVF, PVDF, FEVE, etc.) coated on metal plates and then baked at high temperature.PVDF fluorocarbon coating is the best of existing building coatings, a recognized organic coating with protective effect that guarantees metal building plates for decades and remains beautiful.PVDF fluorocarbon coating has experienced more than 30 years of sun and shine.PVDF was polyvinydene difluoride.The maximum electronegativity of fluorine atoms forms a very stable fluorocarbon bond. coupled with its unique molecular symmetry, PVDF has extraordinary stability, unique anti-UV photohydrolysis performance and excellent insulation performance and mechanical properties.
