| 摘 要： | 通过测试碳钢在模拟腐蚀体系中腐蚀速率的方法,考察了2-甲基咪唑啉、N-甲基二乙醇胺和硫脲三种缓蚀剂的缓蚀性能及其复配效应。研究结果表明,在温度为40℃、pH值为2左右时,单独使用2-甲基咪唑啉、N-甲基二乙醇胺和硫脲这三种缓蚀剂对10号碳钢在酸性体系中都有一定的缓蚀效果。其中2-甲基咪唑啉和N-甲基二乙醇胺的缓蚀效果好于硫脲。这三种缓蚀剂分别与钼酸钠、钨酸钠、苯并三唑复配后的缓蚀效果均好于单独使用缓蚀剂时的效果。

| Abstract: | By testing the corrosion rate of carbon steel in a simulating corrosion system, the corrosion inhibition performance of three corrosion inhibitors (2-methyl imidazone, N-methyl diethanolamine and thiourea) and their compounds was investigated. Results showed that at 40℃ and a system pH value of 2, these three corrosion inhibitors used separately exhibited certain inhibition effect to the corrosion of 10# carbon steel in acidic system, and the inhibition performance of the former two was better than that of thiourea. Synergistic effect was observed when these inhibitors compounded with sodium molybdate, sodium tungstate and azimino-benzene, respectively. |
