复合型缓蚀剂的缓蚀性能

Inhibition efficiency of BTA compound corrosion inhibitor

在考察引起空冷器腐蚀的主要参数,即腐蚀因子(Kp)的条件下,通过配制模拟腐蚀溶液,采用电阻探针腐蚀速率测试装置,在实验室条件下,研究了有机缓蚀剂苯并三唑及其复合物的缓蚀性能。结果表明:缓蚀剂苯并三唑及其复合物之间具有良好的协同缓蚀作用,有效地降低了金属表面的腐蚀速率。

The main parameter of corrosion factor （Kp） that resulted in the corrosion of air coolers, was examined by preparing a simulated corrosive solution, and investgating experimentally the inhibition efficiency of organic corrosion inhibitor of benzotriazole （BTA） and its derivatives with the corrosion rate testing equipment of resistance probe. The results showed that there existed good synergistic effect between corrosion inhibitor of BTA and its derivatives, which reduced effectively the corrosion rate of metal surface.
