以聚环氧琥珀酸（PESA）、聚丙烯酸（PAA）、水解聚马来酸酐（HPMA）、苯并三氮唑（BTA）为原料，研制出一种新型具有环保功能的复合型高效阻垢缓蚀剂。通过正交试验确定该阻垢缓蚀剂中各组分的最佳浓度为：PESA(1.0 mg/L)/PAA(1.0 mg/L)/HPMA (0.6 mg/L)/BTA(0.5 mg/L)。分别采用鼓泡法、电化学试验和旋转挂片腐蚀试验研究了其阻垢缓蚀性能。试验结果表明，该阻垢缓蚀剂的阻垢率为92%，对A3碳钢、铜、不锈钢的缓蚀率分别达到了83%、97%、99%，动态模拟试验结果也显示该阻垢缓蚀剂满足循环冷却水运行要求。

A new kind of efficient environmentally-friendly composite scale and corrosion inhibitor consisting of polyepoxysuccinic acid (PESA) , polyacrylic acid (PAA) , hydrolyzed polymaleic anhydride (HPMA) , benzotriazole (BTA) was developed. The optimal concentrations of such components obtained from orthogonal experiments were PESA(1.0 mg/L)/PAA(1.0 mg/L)/HPMA (0.6 mg/L)/BTA(0.5 mg/L). Its scale inhibition and corrosion inhibition performance was studied with bubble method,electrochemical experiment and rotary weight loss/hanging-piece corrosion experiment. The scale inhibiting rate and corrosion inhibiting rates for A3 carbon steel,copper,stainless steel of the scale and corrosion inhibitor were 92%and 83%,97%,99%,respectively. Further dynamic simulated test also indicated that the scale and corrosion inhibitor meet the demand of circulating cooling water.
