采用碳酸钙沉积法测定5种单一阻垢剂对CaCO3的阻垢效果，聚环氧琥珀酸（PESA）的最佳使用质量浓度为15mg／L时，其阻垢率达到75．3％；在含磷类阻垢剂中，2-膦酸基-1，2，4-三羧基丁烷（PBTCA）的最佳使用质量浓度为20mg／L时，其阻垢率达到76．1％。PESA与PBTCA的浓度比为10：15时，阻垢率可达94．2％。通过正交实验和平行实验，确定三元阻垢剂的最佳配比，即ρ（PESA）：ρ（PBTCA）：ρ（TS-623）（丙烯酸-AMPS三元共聚物）=8：12：8，阻垢率达到96．5％，阻垢效果最佳，且磷含量较低，价格合理，是较为理想的复配型阻垢剂。静态阻垢实验和中试规模的动态试验结果表明，本实验研究的阻垢缓蚀剂能完全适用于工业循环冷却水系统。

Using static scale deposition test determined five different single inhibitors effect on calcium carbonate. The inhibiting efficiency of PESA was 75.3% with mass concentration of 15mg/L. The inhibiting efficiency of PBTCA containing phosphorus was 76. 1% with mass concentration of 20 mg/L. Orthogonal and parallel experiments were taken to obtain reasonable price and non-toxic scale inhibitor. The inhibition efficiency reached 94.2% for the mass concentration proportion of PESA and PBTCA with 10 ： 15. The inhibition efficiency reached 96. 5% for the composite inhibitors with 8mg/L PESA, 12mg/L PBTCA and 8mg/L TS -623. The price is low and is eco-friendly to environment. It taked static state experiment and dynamic testing in moderate scale. Results indicated the composite inhibitors can apply to circulate cooling water.
