本文研究了由高分子聚合物复配的汽蚀缓蚀剂的电化学性能。运用美国普林斯顿应用研究公司生产的332-1腐蚀测试系统,测试了各种缓蚀剂的自然腐蚀电位随时间的变化、线性极化及动电位极化曲线来评价其缓蚀性能,并与美国DCA防冻缓蚀液、苏州产NL乳化液的性能进行了比较。实验证明,用高聚物复配的缓蚀剂对铸铁有很好的缓蚀性能。
In this paper, the electrochemical performance of cavitation corrosion inhibitor complexed with macromolecule polymers was studied. By using the corrosion test system 332-1 produced by Princeton Applied Research Company, the corrosion potential of various corrosion inhibitors was tested with time, the linear polarization and the potentiodynamic polarization curve were used to evaluate the corrosion inhibition performance, DCA antifreeze corrosion solution, produced in Suzhou NL emulsion performance were compared. Experiments show that, with the polymer compound corrosion inhibitor cast iron has a good corrosion inhibition.
