摘　　要：为了更加快速、有效地除去硫酸钡垢,以自主合成AMPS(2-丙烯酰胺-2-甲基丙磺酸)-AA(丙烯酸)聚合物为辅剂,EDTA(乙二胺四乙酸)与DTPA(二乙撑三胺五乙酸)作为主剂研制出一种新型复配除垢剂。研究了EDTA与DTPA质量分数、复配比、pH、温度和聚合物的加入量这5个参数对复配除垢剂性能的影响,得到最优复配。将最优复配除垢剂稀释10倍后,除垢能力和除垢速度得到了大幅度的提高,达到8h除垢量17.4g/L。与国内外现有4种除垢剂进行比较,该复配剂除垢能力和速度具有明显优势。A compound detergent was built by using EDTA（ ethylenediaminetetraacetic acid） and DTPA（ diethylene triamine pentacetate acid） as main agents and using the synthetic AMPS（ 2-acrylamido-2-methyl propane sulfonic acid）-AA polymer as auxiliary agent in order to improve the descaling ability and rate of barium sulfate scale. The effect of 5 factors—mass fraction and compound volume ratios of EDTA and DTPA,p H,temperature and added dose of AMPS-AA polymer to the detergent systems were tested,and obtained the optimal compound detergent. The descaling amount achieved of 10 times diluted the optimal detergent in 8 h reached 17. 4 g / L,and compered to other 4 detergents from home and abroad is obviously better in descaling ability and rate.
