超支化结构阻垢剂的合成及阻垢性能研究

Research on the synthesis of hyperbranched inhibitor and its performance

针对工业循环冷却水在运行过程中不断被浓缩导致的结垢等问题,阐述了超支化结构阻垢剂的合成过程、表征方法和阻垢性能,分析了阻垢剂对碳酸钙和硫酸钙的阻垢效果,并对比研究了合成阻垢剂和商品阻垢剂羟基乙叉二膦酸(HEDP)和聚环氧琥珀酸(PESA)的阻垢性能。结果表明,超支化结构阻垢剂对碳酸钙的阻垢效果不太理想,对硫酸钙的阻垢效果很好,当阻垢剂的浓度为10 mg/L时,阻垢剂对硫酸钙的阻垢率几乎为100%。合成阻垢剂对硫酸钙的阻垢效果优于商品阻垢剂。

Aiming at the scaling due to the concentration of industrial recirculating cooling water during the operation,this paper expounds the synthesis process,characterization and performance of hyperbranched inhibitor,analyzes the effect of the inhibitor on calcium carbonate and calcium sulfate,and compares the performance of the synthetic inhibitor with that of commercial inhibitor HEDP and PESA. The result shows that the effect of hyperbranched inhibitor on calcium carbonate is not ideal,while that on calcium sulfate is great. When the concentration of the inhibitor is 10 mg / L,the inhibition rate,as for calcium sulfate,almost reaches 100%. The effect of hyperbranched inhibitor on calcium sulfate is better than that of commercial inhibitor.
