Polyepoxysuccinic acid (PESA) is a kind new biodegradable water treatment agent. By means of tomparing two kinds of PESA which are synthesized by differently graded raw materials with different dosages,different hardness and different alkality,it is found that PESAI (analytical grade) has better scale inhibitive capacity than that of PESAII (industrial grade). Through scale inhibition capacity test of CaC03,CaSO4, BaSO4, SrSO4 and CaFz and dispersion capacity test of ferric oxide,their inhibition and dispersion efficiencies are evaluated. The results show that under experimental conditions,PESA has excellent inhibitive effect on BaS04 and SrSO4,has comparatively good scale inhibitive effect on CaSO4, CaFO2, and has strong dispersive effect on ferric oxide.
Key words: polyepoxysuccinic acid; scale inhibition; dispersion
