Abstract
In this paper, the effect of sodium lignosulfonate and sodium carboxymethyl cellulose on the stability of a water-coal suspension was studied. As a result, the viscosity of the water-coal suspension was 0.01-0.08 P∙s. The change in dynamic shear rate was considered when adding these plasticizers in different changes. The minimum value of the dynamic shear rate of 13.6 was achieved with the addition of sodium LST plasticizer (SD = 0.1%) in the presence of 40% coal. The influence of alkali on the viscosity of a water-coal suspension was also studied.
