Relation between rheological and structural properties of suspensions

Journal Article:

Abstract

The paper discusses results of investigations into separation processes for coal and kaolin suspensions. Effects of potassium chlorides and methanol additives on electrostatic potential of solid particles and on sedimentation rate are analyzed. Investigation results are shown in 5 diagrams. The relation between rheological and structural properties of coal and clay suspensions is investigated. Investigations show that the non-Newtonian behavior of suspensions cannot be attributed exclusively to the electrostatic and mechanical action of the solid phase particles. It is also caused by structure of the liquid phase, particularly on the surface of the solid particles, which depends mostly on hydrogen bonds. The internal structure of the liquid phase influences differential viscosity much more than the electrical surface properties of the solid phase. Bonds between the molecules of water and methanol are much stronger than bonds between water molecules alone. (9 refs.)
