摘要
采用一步法合成新型两性离子瓜尔胶(ZGG),研究了ZGG水溶液的流变特征,并考察浓度、外加盐等对ZGG水溶液流变性能的影响.结果表明:ZGG水溶液的比浓黏度随浓度的增加而增加;在一定浓度的盐溶液中,ZGG表现出明显的反聚电解质溶液的黏性行为;ZGG水溶液呈假塑性流体特征,具有剪切变稀特性,并具有较强的触变性质.
Zwitterionic guar gum （ZGG） was prepared by one-step method. The rheological characteristics of ZGG aqueous solution were studied on the effect of its concentration and added salts . It was found that the reduced viscosity increased with increasing concentration, and the ZGG solution had characteristics of typical anti-polyelectrolyte. The ZGG solution behaved as pseudoplastic fluids-the decrease in reduced viscosity with increasing shearing-velocity, and had considerably thixotropic response.
