THE EFFECT OF FILLERS ON THE THICKENING POWER OF LITHIUM SOAPS,
Abstract
The thickening effect of lithium soap in three-component systems (oil-soap-filler) depends on the nature of the filler, its concentration, and the nature of the dispersing medium. The addition of fillers (mica or graphite) to lithium greases thickened with a constant quantity of soap increases their strength and viscosity in proportion to the concentration of the filler. In castor-oil greases, the addition of mica increases viscosity and yield value more than graphite does. In cable-oil greases, these two fillers have about the same effect. The addition of up to 10% of mica to greases having constant soap-oil ratio (1:4) increases their yield value. Further increase of filler content to 40% decreases the strength. An increase in graphite concentration gradually decreases the yield value of the grease. The variation of the viscosity of greases with increasing concentration is of external character. (Author)
