Study of Rheological Properties of Sodium Salt Solutions of Carboxymethyl Cellulose

Abstract

Rheological characteristics of polymer solutions not only affect their processing, but can also influence on the structure and properties of products obtained from the solutions. This work is devoted to the study of rheological properties of sodium salt aqueous solutions of carboxymethyl cellulose in water. It is shown that the studied solutions are characterized by the presence of concentration area of unstructured semi-separated solutions without network formation. It is established that the formation of a fluctuation network, accompanied by the change of the transfer mechanism from translation to reposition, as well as the appearance of a break on the curve of viscosity and energy of activation of viscous flow from concentration, occurs when the content of polymer in the solution exceeds 0.3 g/dl. The occurrence of Weissenberg effect and the transition of the system from a behavior characteristic of a viscous-elastic liquid to the one typical of elastic-viscous bodies are observed in solutions with the concentration more than 5 g/dl. The features of rheological behavior of sodium salt aqueous solutions of carboxymethyl cellulose revealed in this work should be taken into account when producing materials based on it.
