摘要

研究了含有膦酰基、羧基的季铵盐缓蚀杀菌剂PS-12对45#碳钢在模拟循环冷却水中的缓蚀性能、杀菌性能及缓蚀机理。失重法和极化曲线测试结果说明:PS-12对45#碳钢具有良好的缓蚀作用,属混合型缓蚀剂。XPS分析结果表明PS-12能与Fe2+、Ca2+等离子螯合,生成螯合物覆盖在金属表面形成性能良好的缓蚀膜。杀菌测试说明PS-12有良好的杀菌性能。

Abstract

Corrosion inhibito r and germicide(PS -12)w hich is a quarternary ammonium salt and has the phosphono-and carboxy g roups, has been studied.The experiment results of the weight loss and polarization experiments show that PS-12 is an excellent corrosion inhibito r for iron in the simulating cooling water.It is found that P-12 belongs to the mixing inhibito r fo r it can block both the anodic and the cathodic reaction.The results of XPS analyses demonst rate that a layer of film is formed when PS-12 chelates Fe2+and Ca2+, and the film grows more completely and compactly w ith the time increasing.The germicidal testing results show that PS-12 has excellent germicidal ability.
