阳离子对CMC溶液流变特性的影响研究
Studies on effects of cation on the rheological properties of CMC solution
摘要
Abstract
CMC has typical poly - electrolytic effect and its rheological properties are influenced by Exogenous ion strength and ion type. In this paper, the effects of different salts (including univalent cation Na+ , K+ and bivalent cation Ca2 + , Mg + ) and different ion strength ( ion concentration is in range from 0% ~ 1 % ) on the rheological properties of CMC solution are studied by the advanced rotational rheometer. According to the experimental results, the ion like Na+ , K+ , Ca2+ andmg2+ had obviously impact on the zero - shearing viscosity, viscosity, shearing thinning index, viscosity damping and visco -elasticity including elastic module G', viscous module G'and loss tangent tan (delta). The mechanism was elaborated in the point of microstructure. Meanwhile, by frequency the scan of CMC, the relation between the dosage of cation and variation of elastic module G'and viscous module G'in low - frequency zone and high - zone were also studied. In addition, turbidity meter and color meter were used to measure the effect of cation and concentration on the turbidity and color (L, a, b).关键词
