2. Features: Because calcium soap forms hydrate with water, calcium soap can only form highly dispersed fibers in mineral oil in the form of hydrate. The hydrate of calcium soap will hydrolyze around 100℃, which is the reason why calcium-based grease gradually loses its consistency above 100℃, which limits the application temperature range of calcium-based grease. If the temperature exceeds 60℃, the calcium-based grease will be softened or even lost, and the lubrication will not be guaranteed.
3. Calcium-based grease has good water resistance and is not easy to emulsify and deteriorate when passing through water. It can be applied to the lubrication of various mechanical parts in wet environment or in contact with water.
4. Calcium-based grease has good shear stability and thixotropic stability. When it is still used after stirring, the grease can still remain on the action surface, resulting in a sealing effect without being thrown out.
5. Calcium-based grease has good pumpability, because calcium-based grease has short fibers and low strength limit. When the same mineral oil is used and made into the same consistency, calcium-based grease is easier to transport than other soap-based (such as sodium-based or aluminum-based) greases.
