摘　　要：利用海水循环冷却动态模拟试验装置,进行阻垢剂聚衣康酸的阻垢性能研究。当聚衣康酸的投加浓度为8 mg/L、浓缩倍数为2.0时,动态模拟试验运行14 d的结果表明,系统年污垢热阻<1.27×10^(-4)m^2·K/W,远低于《海水循环冷却水处理设计规范》(GB/T 23248—2009)中规定的控制指标,ΔA<0.2,阻垢率>97%。The experimental studies on scale inhibition performance of polyitaconic acid （PIA） were carried out by using dynamic simulation experiment device of seawater circulating cooling system. The 14-d operation results showed that the annual fouling resistance was less than 1.27 ×10^-4m^2·K/W, which was far below the control value specified in the Code for Design of Seawater Treatment for Recir- culating Cooling Seawater System （ GB/T 23248 - 2009 ）. The △A was less than 0.2, and the average scale inhibition rate was over 97% under the condition that PIA added in the system was 8 mg/L and the cycle of concentration was 2.0.
