高取代度羧甲基瓜尔胶溶液的微观结构及流变性能
|
摘要
利用环境扫描电子显微镜(ESEM)对粘度在5000mpa.s的高取代度羧甲基瓜尔胶及其降解产物的胶液微观结构进行了表征,并且与海藻酸钠胶液的微观结构相比,显示出不同程度的结构差异。这种结构差异导致其流变行为的差异。结果显示降解高取代度羧甲基瓜尔胶与海藻酸钠胶液的微观结构及流变性能接近,在物理性能和化学性能上较为符合活性染料印花糊料的要求。
The solution microstructures of high substitution carboxymethyl guar gum with different molecular weight and the viscosity at 5000 mpa.s were characterized by environmental scanning electron microscopy(ESEM).Compared with the solution microstructure of sodium alginate,there are different degrees of structural differences,which results in a difference in the rheological behavior.The results show that the microstructure and rheological properties of high substitution carboxymethyl guar gum with middle high molecular weight are similar to the sodium alginate solution,which meet the requirements of reactive dye cotton textile printing paste in physical and chemical properties.
