组合电解质对氧化铁-水悬浮液流变特性的影响

摘要

应用LVDV-Ⅲ＋型可编程流变仪测定了组合电解质对氧化铁—水悬浮液的流变特性的影响。实验结果表明,一价、二价组合电解质在改善悬浮液流变性的同时会使悬浮体系粘度有较大降低;三价组合电解质在改善悬浮液流变性的同时不会使悬浮体系粘度有较大增加。凝聚氧化铁—水悬浮液在测定范围内表现出伪塑性流体的特征。%The rheological parameters of mixed electrolyte treatmented Fe2O3 suspensions were measured by using a programmable LVDV-Ⅲ＋rheometer.Experimental results showed that a bivalent electrolyte composition flow variability to improve the suspension while suspensions would have a greater viscosity reduction,and trivalent electrolyte composition flow variability to improve the suspension would not have the suspension viscosity a largly increase.Condensed oxide-aqueous suspension in the determination showed a range of pseudo-plastic fluid characteristics
