Abstract:

Polyepoxysuccinic acid (PESA) is a new non phosphorus, non nitrogenous, environmentally friendly scale inhibitor. The performance of scale inhibition of PESA is evaluated by scale static beaker tests of CaCO₃CaSO₄·2H₂O?BaSO₄SrSO₄CaF₂ . The experimental results show that PESA has excellent scale inhibition for CaCO₃ ?BaSO₄SrSO₄CaF₂ and a certain extent scale inhibition for CaSO ₄·2H₂O, and is a versatile scale inhibitor.

Key words: polyepoxysuccinic acid, CaCO₃, CaSO₄·2H₂O, BaSO₄, SrSO₄, CaF₂, scale inhibitor

摘要：

聚环氧琥珀酸 (PESA)是-种新型的无磷无氮环保型阻垢剂。通过对CaCO₃ 、CaSO₄·2H₂ O、BaSO₄、Sr SO₄、CaF₂ 的静态阻垢实验,对PESA的阻垢效果进行了评价。结果表明,PESA对CaCO₃ 、BaSO₄、SrSO₄、CaF₂ 垢有极其优良的阻垢性能,对CaSO₄·2H₂ O有-定的阻垢性能,是-种多功能的阻垢剂.
