通过静态容量瓶法研究了不同钙碱浓度条件下,磺酸盐共聚物AA/AMPS同时稳定Zn2+和PO43-的性能。实验结果表明:钙碱浓度对磺酸盐共聚物稳定PO43-和Zn2+性能的影响均较大。 Ca2+介于400~600 mg/L为磺酸盐共聚物对PO43-稳定性的拐点,Ca2+介于600~800 mg/L为磺酸盐共聚物对Zn2+稳定性的拐点;当Ca2+浓度低于拐点时,磺酸盐共聚物对2种离子的稳定性均较好,且受钙碱浓度影响较小;当Ca2+浓度高于拐点时,磺酸盐共聚物对2种离子的稳定性均较差。由于磺酸盐共聚物对钙碱的稳定性能较差,实际应用时需单独投加阻碳酸钙垢性能较好的水处理剂。
通過靜態容量瓶法研究瞭不同鈣堿濃度條件下,磺痠鹽共聚物AA/AMPS同時穩定Zn2+和PO43-的性能。實驗結果錶明:鈣堿濃度對磺痠鹽共聚物穩定PO43-和Zn2+性能的影響均較大。 Ca2+介于400~600 mg/L為磺痠鹽共聚物對PO43-穩定性的枴點,Ca2+介于600~800 mg/L為磺痠鹽共聚物對Zn2+穩定性的枴點;噹Ca2+濃度低于枴點時,磺痠鹽共聚物對2種離子的穩定性均較好,且受鈣堿濃度影響較小;噹Ca2+濃度高于枴點時,磺痠鹽共聚物對2種離子的穩定性均較差。由于磺痠鹽共聚物對鈣堿的穩定性能較差,實際應用時需單獨投加阻碳痠鈣垢性能較好的水處理劑。

By the static volumetric flask method,the simultaneous stabilizing capacities of sulphonate copolymer AA/AMPS for PO43-and Zn2+has been studied under different Ca2+concentration and alkalinity conditions. The re-sults show that the effects of Ca2+concentration and alkalinity on the stabilizing capacities of sulphonate copolymer for both PO43-and Zn2+ are comparatively larger. Ca2+concentration between 400-600 mg/L is the inflection point of the stabilizing capacity of sulphonate copolymer for PO43-. And,Ca2+concentration between 600-800 mg/L is the in-flection point of the stabilizing capacity of sulphonate copolymer for Zn2+. When Ca2+ concentration is below the in-flection point,the stabilizing capacities of sulphonate copolymer for both PO43- and Zn2+ are comparatively good. Meanwhile,Ca2+concentration and alkalinity has less influence on the stabilizing capacity of sulphonate copolymer. When Ca2+concentration is higher than the inflection point ,the stabilizing capacities of sulphonate copolymer for PO43-and Zn2+are poor. Since the stabilizing capacity of sulphonate copolymer for Ca2+concentration and alkalinity is poor,it is necessary to separately add a kind of water treatment agent which has good scale inhibiting capacity for calcium carbonate,in actual application.
