以β-环糊精(β-CD)、马来酸酐(MA)、对苯乙烯磺酸钠(SS)为单体,以过硫酸盐为引发剂,通过溶液聚合方法合成了共聚物阻垢剂(β-CD-MA-SS)。在静态试验条件下评价了其对碳酸钙垢的阻垢性能,考察了共聚物投加量、Ca2+浓度、HCO-3浓度、pH值、反应温度和时间对阻垢率的影响。结果表明:β-CD-MA-SS共聚物具有很好的阻碳酸钙垢性能,共聚物投加量为40mg/L时,阻垢率达到95.04%,适合低硬度、低碱度循环冷却水。
The copolymer scale inhibitor was synthesized by solution polymerization using β-cyclodextrin (β-CD), maleic anhydride (MA) and sodium p-styrenesulfonate (SS) as monomers with persulfate as initiator Agent (β-CD-MA-SS). The scale inhibition performance of calcium carbonate scale was evaluated under static test conditions. The influence of copolymer dosage, Ca2 + concentration, HCO-3 concentration, pH, reaction temperature and time on the scale inhibition rate was investigated. The results showed that the β-CD-MA-SS copolymer has good calcium carbonate scale inhibition performance. When the copolymer dosage is 40mg / L, the scale inhibition rate reaches 95.04%, which is suitable for low hardness and low alkalinity circulating cooling water .
