Continuous process lithium grease production
Chemistry and Technology of Fuels and Oils, 19691. It has been shown that grease made on a continuous process plant with a lithium stearate content of 8% by weight (optimum water content of the initial dispersion and free alkali content of 0.04% NaOH) can meet the GOST standard requirements for grease TsIATIM-201 containing 12% soap. 2. The significant influence of free alkali content

Colloidal properties and microstructure of lithium greases
Chemistry and Technology of Fuels and Oils, 19651. For lithium greases (pure lithium stearate — MVP oil, recooked TsIATIM-210 commercial grease, and the previously studied system of lithium stearate — nonpolar vaseline oil), the general nature of the variation in yield value and syneretic properties has been determined in relation to changes in the temperature schedule of cooling from isotropic ...

The ceria (CeO2) nanoparticles were synthesized by chemical processing, due to its better control on particle size and morphology. The characterization techniques named High-Resolution Transmission Electron Microscopy (HR-TEM) and Energy Dispersive Spectroscopy (EDS) were carried out to confirm the formation of ceria nanoparticles. A uniform suspension

Role of alkali in forming structure of lithium greases
Chemistry and Technology of Fuels and Oils, 1985The present work has been aimed at studying the influence of the high-temperature holding time ("hot-soak" time) and the melt cooling conditions on the individual stages of grease structure formation, depending on the content of alkali. In preparing the greases we used LiSt obtained in grease manufacture by neutralizing the calculated quantities of HSt

Antiwear and extreme-pressure properties of lithium greases
Chemistry and Technology of Fuels and Oils, 19751. The antiwear properties of lithium greases without additives line up with those of the dispersion media, in the following order from poorest to best: PES-3 silicone, MS-6 mineral oil, DOS (dioctyl sebacate). 2. The replacement of lithium stearate by lithium soaps of synthetic fatty acids gives lithium greases with poorer antiwear ...
