hcl介质中双子季铵盐表面活性剂对碳钢的缓蚀性能
, PP. 137-142
Keywords: 双子表面活性剂,季铵盐,碳钢,缓蚀剂,hcl介质
Abstract:
采用质量损失法和电化学方法,研究羟基丙撑双(十二烷基二甲基氯化铵)(hpb)双子型季铵盐表面活性剂在40℃1.0mol/lhcl、kcl、nacl和hcl复配缓蚀介质中对碳钢的缓蚀性能。结果表明:hpb是一种性能优异的缓蚀剂,随着浓度的增大,其缓蚀效率逐渐增大,在质量浓度为50mg/l时,缓蚀效率能达到98%。通过对吸附等温式的探讨,计算出其吸附自由能为-14.64kj/mol,推断出hpb在碳钢表面的吸附行为主要为物理吸附。电化学方法的测试结果表明,hpb是一种以抑制阴极反应为主的混合型缓蚀剂。
