摘要
德赛公司和某电厂针对该电厂的高腐蚀性、负硬度循环水在冬季供暖期的结垢和腐蚀问题进行联合攻关,以聚天门冬氨酸为主剂的配方被用于试验中,结果表明当药剂浓度达到8.0mg/L时△A远远小于0.2,并且对于HSn70-1A和HAl77-2两种铜材腐蚀速率达到了0.0025的优级标准。
The corrosion and scale conrtol for the high corrosion and negative hardness cooling water were studied.In the experiments,polyaspartic acid was used.The results show that△A is less than0.2and the corrosion velocity is less than0.005mm/a when the concentration of inhibitor reaches8.0mg/L.
