Introduction: Calcium base grease is made of mineral lubricating oil with medium viscosity thickened by natural fatty acid calcium soap, and calcium base grease is synthesized It is made of mineral lubricating oil with medium viscosity thickened by synthetic fatty acid calcium soap. Performance characteristics (1) Because calcium soap and water form hydrates, only in the form of hydrates can calcium soap form highly dispersed fibers in mineral oil. The hydrates of calcium soap hydrolyze at about 100 ºC, which is the reason why the calcium base grease gradually loses its consistency above 100 ºC, which limits the temperature range of calcium base grease. Generally, the temperature is not more than 60 ºC. If the temperature is exceeded, the calcium-based grease will become soft or even lose, so the lubrication cannot be guaranteed. (2) Calcium base grease has good water resistance and is not easy to emulsify and deteriorate when passing through water. It can be used for lubrication of various mechanical parts in wet environment or in contact with water. (3) Calcium base grease has good shearing stability and thixotropy stability. When it is agitated and then still in use, the grease can still remain on the action surface, producing sealing effect without throwing out. (4) Calcium base grease has good pumping performance because of its short fiber and low strength limit. When using the same mineral oil and making the same consistency, calcium-based grease is easier to bind than other soap-based grease (such as sodium-based or aluminum-based). Although the calcium-based grease is an old variety in the 1930s, it is still a more widely used variety in the world today. It can be used to lubricate rolling and sliding bearings with medium speed and load in small and medium-sized motors, water pumps, tractors, automobiles, metallurgy, textile machinery, etc
