摘　　要：本文采用静态实验方法,对不同条件下新型阻垢剂膦酰基羧酸共调聚物抑制碳酸钙垢的性能变化规律进行了实验研究。研究表明,在水温低于60℃的情况下,膦酰基羧酸共调聚物具有良好的抑垢性能;在较高硬度时亦有较好的阻垢效果。此外,结合垢粒的电镜照片对其阻垢机理进行了简要分析。结果表明,膦酰基羧酸共调聚物极适于工业循环冷却水系统的水处理过程。An experimental research on changing law of calcium carbonate inhibition behavior ofphosphono carboxylic acid copolymers was carried out by using a static experimental method. As a result, the phosphono carboxylic acid copolymers showed the best calcium carbonate inhibition capability at 60℃ ; when having higher hardness, it had better scale-inhibiting effect. In addition, the mechanism of phosphono carboxylic acid copolymers＇ scale inhibition was analysed through electronic microscope; it was showed that the phosphono carboxylic acid was very suitable for the water treatment process for industrial circulating cooling water system.
