摘要:

通过电化学极化曲线实验,作者主要研究了钼酸盐系列缓蚀剂在自来水中对 A20碳钢的缓蚀情况。指出钼酸盐与正磷酸盐的复配可以达到低浓度、高缓蚀率的效果,而与锌盐之间则不存在协同效应。

关键词: 钼酸盐, 缓蚀, 协同效应

Abstract:

Inhibitive effect of molybdate inhibitor on tap water has been studied, according to electrochemistry polarization curve. It is pointed out that molybdate can reach better inhibitive effect by compatibility with phosphate,and not with zinc sulfate.

Key words: molybdate, inhibition, synergistic effect
