为防止工业循环水结垢,循环冷却水处理技术需要根据实际应用综合考虑补充水量和水质,以提高系统对循环水的阻垢和缓蚀性能。全面分析循环补充水的水质、采用稳定指数RSI来判断循环水结垢腐蚀的倾向,以及对水处理剂的阻垢和缓蚀机理探讨后设计出了含羟基、磺酸基的高效复合阻垢缓蚀剂配方和水系统日常处理方案。通过静态阻垢试验和旋转挂片腐蚀试验验证了配方的合理性和长期运行的稳定性。现场中试验证明了含羟基,磺酸基的高效复合阻垢缓蚀剂应对化工生产过程中处理高硬度、高pH值循环水效果良好。
為防止工業循環水結垢,循環冷卻水處理技術需要根據實際應用綜閤攷慮補充水量和水質,以提高繫統對循環水的阻垢和緩蝕性能。全麵分析循環補充水的水質、採用穩定指數RSI來判斷循環水結垢腐蝕的傾嚮,以及對水處理劑的阻垢和緩蝕機理探討後設計齣瞭含羥基、磺痠基的高效複閤阻垢緩蝕劑配方和水繫統日常處理方案。通過靜態阻垢試驗和鏇轉掛片腐蝕試驗驗證瞭配方的閤理性和長期運行的穩定性。現場中試驗證明瞭含羥基,磺痠基的高效複閤阻垢緩蝕劑應對化工生產過程中處理高硬度、高pH值循環水效果良好。
