THE RHEOLOGICAL FEATURES OF LUBRICATING MATERIALS CONTAINING DISPERSED FILLERS BASED ON HYDROSILICATES OF MAGNESIUM

The effect of dispersed fillers based on magnesium hydrosilicates on the rheological properties of grease is studied. On the basis of an alternative approach to the theory of viscoelastic interaction, taking into account the change in viscosity from the structure change, the coefficients for the Ree and Eyring formula are determined, which govern the nonuniformity of the lubricant. Such coefficients are directly related to the structure and physicomechanical properties. Based on the structural properties of greases, the optimum content of talcite and serpentinite fillers was determined, and the relationship between the number of structural components and its rheology was shown.
