复合缓蚀剂在31%NaCl溶液中的缓蚀性能
INHIBITION PERFORMANCE OF COMPOUND INHIBITOR IN 31% NaCl SOLUTION
摘 要
利用失重法、极化曲线和交流阻抗技术研究了复配缓蚀剂（硫酸锌，葡萄糖酸钙，多聚磷酸钠）对G105钢在31%氯化钠溶液中的缓蚀行为，分析了其缓蚀机理.结果表明，复配的缓蚀剂是一种混合型的缓蚀剂，在80 ℃时，所复配的缓蚀剂在31%氯化钠溶液中的缓蚀率达到了80%以上.

Abstract
Inhibition performance of a compound inhibitor (ZnSO4,CaGL,Na(n+2)PnO(3n+1)) for steel G105 in 31% NaCl solution was studied using weight loss,polarization curve and EIS.The compound inhibitor was a mix-type inhibitor.The inhibition efficiency for the steel in the solution was up to 80% at 80 ℃.
