CHEMISTRY AND CHEMICAL ENGINEERING

Abstract

The aim is to study the effect of the presence of free alkalis and acids on the properties of the complex lithium greases and the choice of the optimal dispersion medium, which provides the required physicochemical characteristics of the developed grease. The dispersed phase of lithium greases studied in the polyalphaolefin oils media. It was found that the use of a mixture of polyalphaolefin oil-4 and polyalphaolefin oil-40 as a percentage of 23/77 with a total content of 83.0% provides a relatively low effective viscosity of the lubricant at low temperatures and a relatively high tensile strength at high temperature.
