摘　　要：以马来酸酐(MA)、丙烯酸(AA)、烯丙基磺酸钠(SAS)和丙烯酸羟丙酯(HPA)为单体,水为溶剂,过氧化氢/次磷酸钠为引发剂,合成了四元聚合缓蚀阻垢剂PMASH。并采用临界pH法、极限碳酸盐法考察了PMASH在不同水质中的运行情况。实验结果表明:当Ca2+和HCO3-均为4 mmol/L时,PMASH的pHc最高可达到9.80,极限碳酸盐硬度可达到7.1 mmol/L,极限碳酸盐碱度可达到6.0 mmol/L,最佳投加量为15 mg/L。热重分析结果显示PMASH耐高温、热稳定性好,可应用于高温水处理系统。With water as solvent and sodium hypophosphite/hydrogen peroxide as initiator, a novel quadripolymer scale and corrosion inhibitor, denoted as PMASH, is synthesized with maleic anhydride（ MA ）, acrylic acid （ AA ）, sodium acrylsulfonate （SAS） and hydroxyl propyl acrylic （HPA）. Its running performance is studied by pH shift method and limited carbonate hardness method. The results indicate that when both [ Ca^2＋ ] and [ HCO3 ] concentrations are 4 mmol/L,the pHc, limited carbonate hardness and limited carbonate basicity can reach 9.80,7. 1 mmol/L and 6.0 mmol/L,respectively. The optimal dosage of PMASH is 15 mg/L. Moreover, the thermogravimetric analysis shows that PMASH has high refractoriness. It can be used in a water treatment system under higher temperature.
