用静态失重法、稳态极化曲线和扫描电镜初步研究了DAMEPNa_2-及DAMEPNa_2-庚烷-戊醇-自来水微乳液对20 ̄#碳钢的缓蚀性能,结果表明(1)两者都为抑制阳极为主的混合型缓蚀剂,(2)该微乳液具有较好的缓蚀性能,缓蚀率可达99%以上,而单一DAMEPNa_2-的缓蚀率仅为16.2%。
The corrosion inhibition properties of DAMEPNa_2- and DAMEPNa_2-heptane-pentanol-tap water microemulsion on 20 ~ # carbon steel were studied by static weight loss method, steady-state polarization curve and scanning electron microscope. The results showed that (1) (2) The microemulsion has good corrosion inhibition performance, the corrosion inhibition rate can reach over 99%, while the corrosion inhibition rate of single DAMEPNa_2- is only 16.2%.
