Abstract:

To study the influence of thicker amount on the rheological properties of lithium grease, the rheological parameters of lithium grease were tested under conditions of steady shear flow and slight oscillation shear flow. By analyzing rheological parameters such as the thixotropy, yield stress and apparent viscosity, storage modulus and strain amplitude, the influences of thicker amount on rheological property were discussed. The results indicate that with increasing thicker content, the viscoelasticity of lithium grease is more significant, the structure of lithium grease is more stable.

Key words: lithium grease, thixotropy, storage modulus, apparent viscosity, strain amplitude
