通过静态容量瓶法研究了不同钙碱水质条件下，磺酸盐共聚物对Zn2＋的稳定性及Zn2＋、Ca2＋和碱度之间的关系。结果发现：钙碱浓度的变化对磺酸盐共聚物稳定Zn2＋的性能影响较大，Ca2＋浓度为600～800mg/L是磺酸盐共聚物对Zn2＋稳定性的拐点，Ca2＋浓度低于600mg/L时，磺酸盐共聚物对Zn2＋稳定性较好，此时碱度为主要影响因素，应重点控制水中的碱度；Ca2＋浓度高于800mg/L时，磺酸盐共聚物对Z n2＋稳定性较差，应该开发高钙条件下专用的稳锌聚合物。

By the static flask methodthis article studiesthe stability to Zn2+ of the sulphonate copolymerin the water quality conditions with the different Ca2+ concentration and alkalinity .The results show that the effects of Ca2+ concentration and alkalinity on the stability to Zn2+ of the sulphonate copolymer are lager . When Ca2+ concentration is 600mg/L -800mg/L ,it is the inflection point of the stability to PO 3 -4 of the sul-phonate copolymer .When Ca2+ concentration is below 600mg/L ,the stability to PO3 -4 of the sulphonate co-polymer is better .During this moment ,the alkalinity is the maininfluencefactor .We should control the alka-linity inthe circulating cooling watermainly .When Ca2+ concentration is higher than 800mg/L ,the stability to PO3 -4 of the sulphonate copolymer is poor .During this moment ,the special polymer to PO3 -4 under the high-calcium water quality conditions need be developed .
