HYDRODYNAMIC MODEL AND KINETICS OF DISPERSION OF A SOLID DISPERSE PHASE IN THE PROCESS OF MIXING IN A VISCOUS LIQUID MEDIUM

A hydrodynamic model of the dispersion of the solid particles of pigments in a liquid in an apparatus with a highspeed stirrer (a dissolver) designed for the production of
finely dispersed and readily dispersible pigments, which can be used as a preliminary stage of the dispersion of pigments in a liquid in which their concentration is high, is proposed. The kinetics of dispersion of solid particles in the process of their mixing in a liquid was investigated. It is shown that the time and rate of dispersion of solid particles in a liquid are dependent on the hydrodynamic and technological parameters of the process. Methods of increasing the output of dissolvers are proposed
