针对含铜冷却水系统发生的腐蚀问题,采用电化学测试、浸泡试验及动水试验等方法,研究了缓蚀剂对铜和不锈钢的缓蚀性能和缓蚀机理。结果表明:甲基苯骈三氮唑+磷酸钠复配方案对铜的缓蚀效果最佳,无论纯水还是恶劣水质条件下,缓蚀剂对铜均具有优异的缓蚀作用。同时,缓蚀剂中的磷酸钠提高了不锈钢的击穿电位,因而提高了不锈钢的抗腐蚀性能。
針對含銅冷卻水繫統髮生的腐蝕問題,採用電化學測試、浸泡試驗及動水試驗等方法,研究瞭緩蝕劑對銅和不鏽鋼的緩蝕性能和緩蝕機理。結果錶明:甲基苯駢三氮唑+燐痠鈉複配方案對銅的緩蝕效果最佳,無論純水還是噁劣水質條件下,緩蝕劑對銅均具有優異的緩蝕作用。同時,緩蝕劑中的燐痠鈉提高瞭不鏽鋼的擊穿電位,因而提高瞭不鏽鋼的抗腐蝕性能。

Based on the corrosion issue of cooling water system containing copper ,the corrosion inhibition properties and protection mechanism of inhibition on copper and stainless steel were studied by performing the electrochemical test ,immersion test and dynamic water simulation test .The results show that corrosion inhibitors have excellent corrosion inhibition efficiency on copper in the condition of either pure water or harsh water . The optimum inhibitor is the compound consisting of TTA and sodium orthophosphate .At the same time , the corrosion inhibitor elevates the breakdown potential of stainless steel and contributes to the enhancement of corrosion resistance .
