摘要
用静态法研究水质稳定剂HEDP、EDTA的阻垢性能。结果表明在常温下单独使用HEDP,阻垢率可达86%,单独使用EDTA阻垢率可达70%,其阻垢率随温度升高皆降低。二者协同作用阻垢率可达98%以上。
The scale inhibiting property of 1-hydroxyethylidine-1,1-diphosphonic acid（HEDP） and Ethylene diamine tetraacetic acid（EDTA） were studied by static method.The scale inhibition efficiency of HEDP used only is 86%.The scale inhibition efficiency of EDTA used only is 70%.The scale inhibition efficiency of HEDP cooperated with EDTA is 98%.The efficiencies of both HEDP and EDTA decrease with temperature increase.
