The specific effects induced by some strong electrolytes or neutral co-solutes on aqueous mixtures of guar gum (GG), sodium alginate (SA) and sodium hyaluronate (SH) were studied through rheology and DSC experiments. The results are discussed in terms of changes in the polymer conformation, structure of the network and hydration properties. This study is also aimed at controlling the viscosity of the aqueous mixtures for application in green formulations to be used as fracturing fluids for shale gas extraction plants.
通过流变学和 DSC 实验研究了一些强电解质或中性共溶剂对瓜尔胶（GG）、海藻酸钠（SA）和透明质酸钠（SH）在水溶液中的混合物的具体影响。根据聚合物构象、网络结构和水合性质的变化来讨论这些结果。本研究还旨在控制水相混合物的粘度，以用于绿色配方中，作为页岩气开采厂压裂液。
