DETERMINATION OF PHYSICO-CHEMICAL CHANGES IN THE PROPERTIES OF CLAY UNDER THE COMPLEX INFLUENCE OF CHEMICAL REAGENTS AND MECHANOACTIVATION

Abstract

The main source of bentonite raw materials for drilling fluids in Kazakhstan is imported, which makes available domestic technologies for producing high-quality clay powders, especially taking into account the need to supply raw materials for drilling fluids. The production of clay powders for drilling using a raw material base of clay raw materials requires obtaining colloidal chemical properties of clays in ways that can be both technically feasible and economically effective using existing, readily available raw materials. In the course of our research, we investigated the processes of physico-chemical interaction of Darbaza clay with reagents used to modify clay powders; the influence of mechanical activation processes and modifier reagents during clay dispersion on changes in its colloidal chemical, mechanical and technological properties has been studied; it has been established that when mechanical activation processes affect the colloidal chemical properties of clays, not
