在工业级次氯酸钠溶液对不锈钢管耐蚀性能的影响和一些杀生剂的杀菌效果试验中 ,次氯酸钠是否会对不锈钢管的耐蚀性能有不利影响要视具体水质工况条件而定 ,一般应通过试验确定 ,七台河电厂正常的冷却水工况条件对 3 0 4不锈钢的耐蚀性能基本上没有影响。在七台河电厂冷却水工况条件下含溴氧化性杀生剂 JA-K5 0 0的用量只有次氯酸钠溶液的 1/10 ,杀菌效果却比次氯酸钠溶液高得多。氧化性杀生剂应与非氧化性杀生剂交替使用 ,非氧化性杀生剂可以选择JA-981或 JA-3 0 6,加药浓度为 180 mg/L。
In the industrial-grade sodium hypochlorite corrosion resistance of stainless steel and some biocides sterilization effect test, whether sodium hypochlorite corrosion resistance of stainless steel pipe will adversely affect the specific conditions of the water quality conditions should generally pass the test It is confirmed that the normal cooling water conditions of Qitaihe Power Plant have basically no effect on the corrosion resistance of 304 stainless steel. Under the conditions of cooling water in Qitaihe Power Plant, the dosage of brominated oxidizing biocide JA-K5 0 0 is only 1/10 of that of sodium hypochlorite solution and the bactericidal effect is much higher than that of sodium hypochlorite solution. Oxidizing biocides should be used interchangeably with non-oxidizing biocides. JA-981 or JA-300 can be used as the non-oxidizing biocide at a concentration of 180 mg / L.
