摘　　要：文中研究了Moesslein牌Folmar型磷酸盐复合缓蚀剂对PE、PVC、PPR、不锈钢、球墨铸铁、白铁和钢塑共7种不同材质供水管道的缓蚀控制。结果表明,当缓蚀剂投加量为10mg/L时,缓蚀剂对各管材总硬度和总氯均起到了明显的控制作用,说明该缓蚀剂有利于提高管道内的化学稳定性和生物稳定性。In this paper,the corrosion control of Moesslein Folmar phosphate compound corrosion inhibitor on pipes of PE,PVC,PPR,stainless steel,ductile iron,white iron and steel-plastic was studied.The results showed that when the corrosion inhibitor was added at 10 mg/L,the corrosion inhibitor had obvious effects on the total hardness and the residual total chlorine(monochloramine)of each pipe,indicating that the corrosion inhibitor was beneficial to improve the chemical and biological stability of the pipeline.
