Study of the versatile scale inhibition of polyaspartate

Abstract: 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 CaCO 3, CaSO 4 ·2H 2 O,BaSO 4, SrSO 4 under static condition. The results show that PASP is of excellent scale inhibition for CaCO 3, CaSO 4 ·2H 2 O, BaSO 4,SrSO 4.
