在高温下操作的设备重新涂漆时,通常要用很多的时间。因为设备在涂漆以前必须冷却到环境温度。如果在涂漆时还要进行其它工作的话,涂漆所要求的表面喷砂处理会使别的检修作业不好进行。美国Amoco 石油公司炼油厂的设备采用一种耐化学腐蚀和耐热的涂料。这种涂料可用于表面温度为200℃的设备上。该涂料是在1976年研制的,它不需要预先在表面涂底漆,是以硅酮共聚物为主制成的。它含有较多的抑蚀性颜料和由热激发的活化剂,从热的基底散出的热可激发此活化剂,并使涂层形成没有气孔和针眼的薄膜,
It takes a lot of time to repaint a device operating at high temperatures. Because the equipment must be cooled to ambient temperature before painting. If other work is to be done while painting, the surface blasting required by the paint will make other overhauling work poor. Equipment at the Amoco refinery in the United States uses a chemical and heat resistant coating. This coating can be used on equipment with a surface temperature of 200 ° C. The paint was developed in 1976, it does not require pre-priming the surface, is based on the silicone copolymer made. It contains more inhibitory pigments and heat-activated activators. The heat dissipated from the hot substrate excites this activator and causes the coating to form a film free of pores and pinholes,
