Affecting of high-speed shift on rheological behavior of aqueous solutions of mixes sodium carboxymethylcellulose and hydroxyetylcellulose

Abstract

Properties of diluted and moderate-concentrated aqueous solutions NaCMC and their mixes have been studied by viscosimetry and rheology methods. Last years the attention of researchers has been involved in the self-associated polymeric systems on the basis of natural polysaccharides. Sodium carboxymethylcellulose and hydroxyetylcellulose, widely applied in the capacity of gelling agents, stiffeners, stabilizers and emulsors refer to such polymers. Use of the given cellulose ethers in edible, textile, oil and other industries is in many respects defined by their ability to biodecomposition [1-3]. The mechanochemical activation refers to one of the effective control modes of processes of gelation in solutions of such polysaccharides in the conditions of an act of high-speed shift. However mechanochemical processes in solutions of polymers are not enough studied. It is caused by the fact that at mechanical affecting on solutions of polymers in activators of rotorno-pulsing type is a whole complex of the phenomena, such as a mechanical cracking, a mechanodestruction, phase and conformational transformations of macromolecules, which are rather difficult to divide [4,5]. In the present message agency of machining on structural and rheological behavior of aqueous solutions sodium carboxymethylcellulose, hydroxyetylcellulose and their mixes is observed.
