通过失重法研究了 2 -巯基嘧啶对锌在磷酸溶液中的缓蚀作用 .结果表明缓蚀剂对锌在磷酸溶液中有较好的缓蚀效果 ,缓蚀作用是由于缓蚀剂在金属表面形成保护膜 ,且未改变腐蚀过程的速率决定步骤机理
The inhibition of 2-mercaptopyrimidine to zinc in phosphoric acid solution was studied by weight loss method.The results showed that the corrosion inhibitor had good corrosion inhibition effect on zinc in phosphoric acid solution, and the corrosion inhibition was due to the corrosion inhibitor on the surface of metal The formation of a protective film, and did not change the rate of corrosion process determines the mechanism of the step
