摘　　要：通过卤水长期浸泡对工业用硬聚氯乙烯(PVC-U)管道腐蚀情况展开研究,工业用硬聚氯乙烯(PVC-U)管道经过卤水长期浸泡后管道物理力学性能变化很小,分子微观结构无变化。因此,工业用硬聚氯乙烯(PVC-U)管道耐卤水腐蚀。In this paper,a study was carried out on the rigid polyvinyl chloride(PVC-U)pipe corrosion situation when being long-term soaked in industrial brine.Through the analysis on the pipe physical mechanical properties and molecular microstructure changes in such situation,it was discovered that the brine has no any effect on the behaviors of PVC-U pipes.In conclusion,PVC-U pipes have resistance to corrosion of the brine.
