1) the thixotropy

Grease is the most basic characteristic, is the thixotropy. Upon application of a force, lubricating grease flowing in gradually became soft, viscosity reducing, but when at rest, after a period of time ( very short ), consistency increased again ( recovery), this is called thixotropy. Grease the characteristic, decided its can not suitable for lubricating parts of lubrication, and show its excellent performance.

2) viscosity

Grease is usually apparent viscosity or similar viscosity to express, in grease viscosity, temperature and shear rate must be specified. Using similar viscosity index to control the flow and pumping.

3) the strength limit

Grease the strength limit refers to the sample to start the flow of the minimum shear stress, also known as the ultimate shear stress. Grease ultimate strength is a function of the temperature, the higher the temperature grease strength limit of the smaller, lower temperature, lipid ultimate strength becomes large, its size depends on the thickening agent type and content, and the grease production process conditions also have a certain relationship.

4) low temperature fluidity

A measure of grease performance at low temperature is one of the important indices of low temperature torque, i.e. at low temperature ( 20°C ) grease block low speed flow bearing the degree of rotation, low torque grease from the starting torque and the rotational torque of 60MM mean value.
