摘要
论述了1-苯基-5巯基四氮唑 (PMTA) 所具有的独特性质在防银变色方面的应用. 考察了温度、浓度、溶剂等因素对其防银变色效果的影响, 通过测定 PMTA钝化膜的抗H_2S腐蚀能力及其接触电阻, 得出了较好的防银变色缓蚀剂配方及操作工艺.
The paper discussed the application of 1-phenyl-5-mercaptotetrazole (PMTA) with many inimitable characters in preventing silver tarnish, and investigated the influences of various factors such as temperature, concentration and solvent on preventing silver tarnish. The optimum prescription of corrosion inhibitor and operation technique were obtained through measuring the contact resistance and the resitance to H_2S corrosion.
