摘　　要：以PSI为原料合成了含羟基聚天冬氨酸接枝共聚物,研究了接枝不同比例的共聚物对碳酸钙的阻垢性能及与磁场的协同阻垢作用。结果表明,含羟基聚天冬氨酸接枝共聚物对碳酸钙的阻垢性能有所下降,但其与磁场具有很好的协同作用。其中,接枝比例为1.0的共聚物与磁场的协同作用最明显,在药剂用量为8mg/L时,阻垢率提高了22.9%。Polyaspartic acid graft copolymers containing hydroxyl were synthesized with PSI as the raw material.The scale inhibition performance of the graft copolymers and that in magnetized water were studied by static scale inhibition test.The results showed that the scale inhibition performance of the graft copolymers were declining with the increase of graft ratio.But the graft copolymers and the magnetic field have good synergistic.When the graft ratio was 1.0,the scale inhibition increased 22.9% at a dosage of 8mg/L,and the synergistic was the best of all the graft copolymers.
