摘要
对水解聚马来酸酐(HPMA)和乙二胺四亚甲叉膦酸钠(EDTMPS)的复配物阻垢性能进行研究。考察阻垢剂添加量、pH值、Ca2+浓度、HCO3-浓度、恒温时间对阻垢率的影响。实验发现,当HPMA和EDTMPS质量配比为3∶1,总加入量为10mg/L时效果最佳,阻垢率达98%。复配物阻垢性能受时间的影响较小,受Ca2+浓度的影响较大。
The scale inhibition performance of HPMA- EDTMPS compound scale inhibitor was studied. The effects of dosage of scale inhibitor, temperature, mass concentration of Ca^2＋、HCO3^-and pH, constant temperature time on scale inhibition rate were investigated. The optimal mass proportion for the compound was 3：1, when the total dosage of HPMA and EDTMPS was 10 mg/L, the scale inhibitionrate reached 98%.Time and mass concentration of HCO3^- have little influence on the scale inhibition performance of the compound, however, the influence of mass concentration of Ca^2＋ was bigger.
