【Abstract】 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.更多还原
