复配型水处理剂的阻垢缓蚀性能初步研究

摘要

采用静态阻垢法和旋转挂片失重法评定了在高浓度钙离子水系统中的水处理剂的阻垢性能和缓蚀性能，并研究了栲胶与水处理剂复配后水处理剂的阻垢缓蚀性能。结果表明，PBTCA具有广泛高效的阻垢性能，可忍受较高的Ca2+浓度。栲胶与PBTCA、HPMA复配后在阻垢性能上具有良好的协同效应，当栲胶与PBTCA配比为3∶1时，阻垢缓蚀性能最佳。%The anti scale and anticorrosion performances of water treatment reagent were accessed by the static method and rotary hanged weight loss method. The antis anti scale and anticorrosion performances of composite water treatment reagent of tannin acid with PBTCA and HPMA were studied. The results showed that PBTCA was more efficient even in high Ca2+concentration water system. In addition, there were synergistic effects between tannin acid and PBTCA. When the rate of tannin and PBTCA was 3∶1, it showed the best performance of anti scale and anticorrosion.
