生物可降解聚天冬氨酸阻垢性能的研究

Study of the versatile scale inhibition of polyaspartate

聚天冬氨酸(PASP)是一种无磷环保型阻垢剂。通过CaCO3,CaSO4·2H2O,BaSO4,SrSO4的静态阻垢实验,对PASP的阻垢效果进行了评价。结果表明,PASP对CaCO3,CaSO4·2H2O,BaSO4,SrSO4垢有极其优良的阻垢性能,是一种多功能的阻垢剂。

Polyaspartate (PASP) is a new non-phosphorus and environmentally friendly polymer, which can act as a kind of scale inhibitor. The performance of scale inhibition of PASP is evaluated by scale beaker tests of CaCO3, CaSO4·2H2O,BaSO4, SrSO4 under static condition. The results show that PASP is of excellent scale inhibition for CaCO3, CaSO4·2H2O, BaSO4,SrSO4.
