摘    要:通过静态失重法研究了十二烷基苯磺酸钠(SDBS)与六亚甲基四胺(HA)在盐酸溶液中对Q235钢的协同缓蚀效应, 并采用分子动力学模拟从缓蚀剂膜抑制腐蚀粒子扩散的角度对其缓蚀机理进行分析. 结果显示: SDBS和HA单独使用时, 最高缓蚀效率分别为82.82%和79.46%, 复配后最高缓蚀效率可达到92.78%; 与两种缓蚀剂单独使用时相比, SDBS与HA复配后缓蚀剂膜体系中的自由空间明显下降, 削弱了膜内缓蚀剂分子的自扩散能力, 腐蚀粒子在缓蚀剂膜携带下的被动迁移也随之减弱; SDBS与HA复配能更有效抑制腐蚀粒子在缓蚀剂膜中的扩散, 也就是说复配后的缓蚀剂具有更好的缓蚀性能.

关 键 词:十二烷基苯磺酸钠  六亚甲基四胺  失重法  分子动力学模拟  扩散系数

Abstract:The synergistic inhibitive effect of sodium dodecylbenzene sulfonate(SDBS) and hexamethylene tetramine(HA) toward Q235 steel in hydrochloric acid was investigated by the static weight loss method.We also studied the inhibition mechanism by molecular dynamics simulations with regard to the inhibition of aggressive particle diffusion by inhibitor membranes.SDBS and HA were found to have individual inhibition efficiencies of 82.82% and 79.46%,respectively.These inhibition efficiencies increased to an efficienc...
Keywords:Sodium dodecylbenzene sulfonate  Hexamethylene tetramine  Weight loss method  Molecular dynamics simulation  Diffusion coefficient
