Effect of composition of oils and synthetic fatty acids on properties of lithium greases

From the History of Creation of Plastic Lubricants. Basic and Applied Research

“…The thickening effect of the soap mixtures obeys the law of additivity. By varying the physicochemical nature of the dispersion medium, thickeners, and additives, the bulk-mechanical, lubricant, and other properties of greases can be flexibly regulated, and the SF plays the main role here[16][17][18].The functional role of oxygen-containing SF in different stages of structure formation was discovered and their effect on the properties of soap greases was demonstrated. For the favorable evolution of association of molecules, micelle and soap fibre formation, formation of the structural backbone of the grease, such SF should be present in the necessary amount in the feedstock or formed during manufacture of the grease as a result of oxidation of its components (process SF).The intensity and degree of completion of crosslinking and in the final analysis, the flow and boundary properties of greases are a function of the type and concentration of SF.…”
