Effect of molybdenum disulfide on properties of lithium greases
Chemistry and Technology of Fuels and Oils, 19671. The addition of from 1 to 30% MoS2 to TsIATIM-201 lithium grease had practically no effect on yield value at 20–80°C, viscosity at −50 to +50°C, mechanical stability, or heat hardening. MoS2 does not have any appreciable thickening capability when it is added to the grease either cold or with remelting. 2.

Evaluation of Calixarenes as Antioxidants in Complex Lithium Grease
Chemistry Letters, 2014Abstract The thermal stability and antioxidant performance of 4-tert-butylcalix[4]arene (B4) and 4-tert-butylcalix[8]arene (B8) were investigated and compared with those of 3,5-di-tert-butyl-4-hydroxytoluene (BHT). Both B4 and B8 were superior to BHT in thermal stability. In addition, B4 and B8 also showed obvious antioxidant capacity in

Processing and Formulation of Lithium Lubricating Greases
AIP Conference Proceedings, 2006The effects that soap concentration, base oil viscosity and additives exert on the rheology of lubricating greases have been studied. Also, changes in both microstructure and rheology of lithium lubricating greases during their manufacturing process have been evaluated.

Continuous lithium and aluminum stearate grease manufacture
Oil & Soap, 19441. Lithium and aluminum greases can be made continuously by using heating, cooling, gelling and working stages in series. Votators can be used successfully for heating, cooling and working. The entire process from slurry to finished grease takes about 20 minutes, most of which time is in the gelling section.

The mechanism of pigment grease stabilization by lithium adipate
Chemistry and Technology of Fuels and Oils, 19681. It has been established that the direction and kinetics of property changes in greases at high temperatures are the result of the interaction of effects of two processes which exert the opposing effects of polymerizing the dispersion medium and decreasing the particle concentration of the disperse phase. 2.

Thermoanalytical investigations on lithium stearate, lithium 12-hydroxystearate and related greases
Journal of Thermal Analysis, 1985TG and DSC techniques proved useful in the study of the thermal properties of lithium stearate, lithium 12-hydroxystearate and related greases. Under an inert atmosphere, the stearates decompose into the oxalate prior to the formation of the carbonate.

Preparation of lithium greases by the use of internal and external polarization
Chemistry and Technology of Fuels and Oils, 19751. The feasibility of using internal chemical and external polarization in lithium-grease manufacture has been investigated. Only by the joint use of the two factors in polarization action on the system, both in the stage of thermomechanical dispersion and in the stage of cooling and crystallization, is it possible to obtain greases with optimal ...

Effects of Graphene Nanoadditive on the Lubrication Performance of Lithium Grease
Academic Conferences SeriesIn this study, graphene nanoplatelets were blended with lithium base grease in the range of 0 wt%-1 wt% amount, and lubrication behaviors were examined by means of four-ball friction test system. First, the graphene and grease materials were observed by scanning electron microscope (SEM), transmission electron microscopy (TEM), and Raman spectroscopy ...
