REDISPERSION OF POWDERS IN A LIQUID-MEDIUM

A model of powder redispersion in a liquid medium is proposed. For the specific case of establishing an equilibrium in the system ''equilibr ium aggregates reversible arrow primary particles,'' the dependence of the equilibrium degree of redispersion on the volume fraction of the solid phase, on the size of equilibrium aggregates, and on the energy of interaction between particles is determined. The influence of the c oncentration of the solid phase on the coagulation rate of disperse sy stems is discussed.
