合成了含不同质量比的羟基基团的聚天冬氨酸衍生物,研究了其对CaCO3、Ca3(PO4)2和CaSO4的阻垢性能,并与聚天冬氨酸进行比较。结果表明:当n(AE)∶n(PSI重复单元)=0.1∶1时,对CaCO3和CaSO4的阻垢性能最好;当n(AE)∶n(PSI重复单元)=0.5∶1时,对Ca3(PO4)2的阻垢性能和综合阻垢效果最佳,在药剂质量浓度为14 mg/L时,对CaCO3、Ca3(PO4)2和CaSO4的阻垢率分别为54.8%、100%和97.2%。
閤成瞭含不同質量比的羥基基糰的聚天鼕氨痠衍生物,研究瞭其對CaCO3、Ca3(PO4)2和CaSO4的阻垢性能,併與聚天鼕氨痠進行比較。結果錶明:噹n(AE)∶n(PSI重複單元)=0.1∶1時,對CaCO3和CaSO4的阻垢性能最好;噹n(AE)∶n(PSI重複單元)=0.5∶1時,對Ca3(PO4)2的阻垢性能和綜閤阻垢效果最佳,在藥劑質量濃度為14 mg/L時,對CaCO3、Ca3(PO4)2和CaSO4的阻垢率分彆為54.8%、100%和97.2%。
