摘　　要：在ρ(Ca2+)=ρ(HCO3-)=250mg/L的模拟循环水中,PESA、HEDP、AA/AMPS三种药剂对A20钢的阻垢性能优劣顺序是:PESA>HEDP>AA/AMPS;最佳复配方是HEDP 2.5mg/L、PESA 1.5mg/L、咪唑啉1.5mg/L。复配药剂具有良好的缓蚀阻垢效果,缓蚀过程以抑制阳极为主,阻垢作用通过配位作用和晶格畸变二者的协同作用实现。In simulated cooling water, the sequence of the inhibition performance of the fouling inhi- bitions was PESA 〉 HEDP 〉 AA/AMPS when the concentrations of Ca^2 ＋ and HCO^3 - were 250 mg/ L. The best compound formula contained 2.5 mg/L of HEDP, 1.5 mg/L of PESA and 1.5 mg/L of imidazoline. A compound formula that screened has a good corrosion and scale inhibiting performance. The corrosion inhibition process depended on inhibiting anodic reaction mainly. The scale inhibiting were proved through polycomplexation and aberration of crystal effects cooperated with each other.
