Brief introduction:
Calcium grease is a commonly used grease, which is mainly made from animal and plant oil (synthetic fatty acid with synthetic fatty acid for synthesis of calcium base grease) and calcium soap made of lime to thicke medium viscosity mineral lubricating oil, and water as a rubber solvent.
Main use:
Calcium grease is mainly used for automobile, tractor, pump, small and medium-sized motor and other industrial and agricultural machinery rolling bearings and easy to contact with water or moisture lubrication. • Calcium base grease is generally used for rolling bearings with a speed below 3000r/min.
Characteristics and performance:
Calcium-based grease has good water resistance, is not easy to emulsify in water, and can be used in humid environments or in contact with water.
It has good shear stability and thixotropic stability, and less oil in storage.
The drop point of calcium-based grease is high, but the heat resistance is relatively poor, and the maximum use temperature is usually not more than 60 ° C ~70 ° C. Beyond this temperature, the grease will become soft or even structurally damaged and lose lubrication.
Calcium grease is relatively cheap, is one of the early widely used grease varieties
