摘要
研究了BTA,MBI,MBT等3种铜缓蚀剂在H2S环境中的缓蚀性能,采用量子化学研究方法对实验结果进行了分析,研究了苯三唑在铜表面所形成的配合物保护膜的稳定性。结果表明,MBT抗H2S腐蚀性能较差,BTA是铜及其合金在H2S环境中理想的接触缓蚀剂和气相缓蚀剂。
The existence of H2 S in environment is one of the factors causing discoloration of Cu.The inhibition of BTA,MBI,MBT,and the stability of BTA –Cu protection layer in H2 S atmosphere were investigated.The experimental results were analyzed by quantum chemistry calculation method.Results indicated that BTA is a perfect corrosion inhibitor for Cu in H2 S environment while the performance of MBT is discontented.
