由于彩涂板不僅具有優(yōu)良的抗氧化、抗腐蝕等特性，而且顏色更加豐富多彩，傳統(tǒng)的鍍鋅板管道防腐已逐漸被彩板所取代。管道保溫防腐彩板選用建議采用鋅層不低于80克/平米，正面涂層厚度不低于20um的普通PE聚酯彩板。對(duì)于野外的石油、天然氣輸送管道，考慮到管道所處的特殊環(huán)境，建議采用PVDF氟碳彩板、佛山萬(wàn)慶高性能聚酯彩板或HDP高耐候彩板。氟碳涂層板是使用氟碳樹(shù)脂（PVF、PVDF、FEVE等）的氟碳涂料涂裝在金屬板上，再經(jīng)高溫烘烤做成的金屬烤漆涂層板。PVDF氟碳涂層為現(xiàn)有建筑涂層中的極品，為公認(rèn)的具有保護(hù)作用的有機(jī)涂層，能保證金屬建筑板幾十年不受損害并始終保持美麗的顏色。PVDF氟碳涂層在世界各地的建筑物經(jīng)歷了30多年的日曬風(fēng)吹雨打，始終保持顏色靚麗。PVDF為聚偏二氟乙烯。氟原子最大的電負(fù)性能形成十分穩(wěn)固的氟碳鍵，加上其分子獨(dú)特等對(duì)稱性，使PVDF具有超常的穩(wěn)定性，獨(dú)特的抗紫外光光解性能及優(yōu)異的絕緣性能和機(jī)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.
