Abstract

A method for producing plastic and liquid lubricants characterized by conducting a dispersion of the starting components, such as thickeners or reagents for the formation thereof, additives and fillers and base liquids into a vortical bed of ferromagnetic particles formed under the action of a rotating magnetic field. The proposed method makes it possible to reduce the duration of chemical reactions between the dispersed components of lubricants by thousands of times as compared to the known batch processes and by dozens of times as compared to the known continuous processes. The method provides continuous conduction of technological processes with high productivity, reduces by 10-20% specific consumption of expensive components, by 2-3 times the consumption of energy, and allows the process to be conducted at lower temperatures and pressures.
