摘要
锦州石化公司 3 0 0 0m3炼油污水储罐因Cl- ,NH3,CN- 和酚等腐蚀介质的影响 ,致使原环氧防腐蚀涂层失效并有 3 0 0多处点蚀穿孔。经试验 ,聚硫橡胶改性环氧树脂对上述介质有良好的耐蚀性 ,随后用环氧聚硫橡胶玻璃鳞片玻璃钢内衬对储罐进行了修复 ,经近 4年使用 。
On the 3000 m 3 refinery waste water tank in Jinzhou Petrochemical Company, the epoxy resin corrosion protection coating failed and more than 300 pittings were found due to the corrosion media of Cl -, NH 3 and CN -. The test demonstrated that the polysulfide-rubber-modified epoxy was highly resistant to the corrosion by above corrosive media. The tank was then repaired using FRP lining with polysulfide rubber glass scale and has been operating for four years without any problem ever since.
