微晶纤维素胶体性质的研究

A Study on the Properties of Microcrystalline Cellulose gel

微晶纤维素悬浮液在机械力的作用下发生微纤化而形成胶体。本文用流变仪研究了微晶纤维素胶体溶液的速度梯度与应力、浓度与粘度、温度与粘度之间的关系；同时研究了酸碱性、盐类对粘度的影响，以及胶体的储存稳定性。此外，用电导仪测量了胶体的电性质，展示了微晶纤维素胶体的独特性质。

The microcrystalline cellulose (MCC) gel can be formed by the mechanic shear force on the microcrystalline cellulose suspension. The rheologic properties of the MCC were investigated with viscometer including the relationship of the shear rate and shear stress, the relationship of the concentration or themperature and viscosity, the effect of the salts addition on the viscosity and the stability of the gel during the standing.Additionally, the e1ectric conductivity of the MCC gel was measured, All of the experiment showed the special properties of the MCC gel.
