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。
應用LVDV-Ⅲ+型可編程流變儀測定瞭組閤電解質對氧化鐵—水懸浮液的流變特性的影響。實驗結果錶明,一價、二價組閤電解質在改善懸浮液流變性的同時會使懸浮體繫粘度有較大降低;三價組閤電解質在改善懸浮液流變性的同時不會使懸浮體繫粘度有較大增加。凝聚氧化鐵—水懸浮液在測定範圍內錶現齣偽塑性流體的特徵。

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
