The result showed that, the effect of the synergistic reaction of alkyl-phenol-polyoxythylene ether phosphate dispersant TERSPERSE 4896, nonyl phenyl polyoxyethylene ether dispersant TERSPERSE 2210 and XG to suspension was different. Both the rheological curves were same presented as pseudoplastic fluid when they stored in R. T (18~25℃) for 10 days, but the rheological curve of suspension with the synergistic reaction of TERSPERSE 2210 and XG was changed to dilatant fluid when it stored in R.

结果表明，烷基酚聚氧乙烯磷酸酯类分散剂TERSPERSE 4896、壬基酚聚氧乙烯醚类分散剂TERSPERSE 2210与增粘剂黄原胶协同使用所得悬浮体系，室温(18~25℃)贮存10d仍表现出二者共同的流变特性，呈假塑性的流变曲线；但室温贮存150d后，含TERSPERSE 2210与黄原胶的悬浮体系的流变性质发生了明显变化，由假塑性流体向膨胀型流体转变。
