Dependence of Properties of Lithium Complex Greases Based on Synthetic Base Oils from the Viscosity of Dispersion Medium and the Composition of the Thickener Agent

This experiment is concerned with the preparation of a lithium complex soap grease having some principal advantages: good low temperature properties and high dropping point. As a thickener high molecular weight fatty acids (12-hydroxystearic acid) and aliphatic dicarboxylic acids (sebacic acid) were...

Description
Summary:This experiment is concerned with the preparation of a lithium complex soap grease having some principal advantages: good low temperature properties and high dropping point. As a thickener high molecular weight fatty acids (12-hydroxystearic acid) and aliphatic dicarboxylic acids (sebacic acid) were used. Dependence of properties of lithium complex greases based on synthetic base oils from the viscosity of dispersion medium were studied. The resulting samples satisfy the requirements of the lithium complex soap greases, also have better low temperature properties. Present results may be used for the further development of the technology of lithium complex soap grease producing.
