The main objective of this study was to evaluate the efficacy of a biocide and a corrosion inhibitor against the corrosion of a circulating pipe in a cooling tower. Isothiazolone was tested as the industrial biocide. The results showed that the biocide by itself or combined with a dispersant was not efficient to control corrosion in the industrial system. Corrosion rates of 0.324 mm/year were recorded in both the presence and absence of the biocide. Corrosion control was successfully accomplished by using a corrosion inhibitor. In the latter case the maximum corrosion rate of 0.024 mm/year were obtained.
本研究的主要目的是评估一种杀生剂和一种缓蚀剂对冷却塔中循环管道腐蚀的抑制效果。以异噻唑啉作为工业杀生剂进行测试。结果表明，单独使用杀生剂或与分散剂联合使用，在工业系统中控制腐蚀的效果不佳。无论是否存在杀生剂，腐蚀速率均为0.324毫米/年。使用缓蚀剂成功实现了腐蚀控制。在后一种情况下，最大腐蚀速率为0.024毫米/年。
