【摘要】 二氧化氯具有优良的杀菌性能,在循环冷却水的处理中常作为杀生剂。由于其强氧化性,对循环水设备很容易造成腐蚀。本文研究了HEDP-ClO₂对冷却水设备常用材质-碳钢的缓蚀性能。实验表明:在pH值为9,温度为40℃,ClO₂投加浓度为2mg/L,HEDP投加浓度为15.0mg/L时,可以达到最好的缓蚀效果。更多还原

【Abstract】 The disinfection effects of chlorine dioxide in circulating cooling water was very good.It was usually used as disinfector.Because it has strong oxidation,ClO₂ can corrupt equipment of circulating cooling water system.We have studied the incrrosion compatibility of HEDP- ClO₂ to mild steel.The results of the test indicate that when the pH is 9, temperature is 40℃,dosage of ClO₂ is 2mg/L,dosage of HEDP is 15.0 mg/L,the effect ofincrrosion can be very well.更多还原
