Maxtop calcium-base grease is refined by thickening mineral base oil with animal fatty acid calcium soap. It has good water resistance and mechanical stability. However, because the hydrate generated by calcium soap and water will be hydrolyzed at about 100 ° C, it will become soft and even lose when it exceeds 60 ° C, so the general use temperature does not exceed 60 ° C. Calcium grease is mainly used in the fields of iron and steel, mining, automobile and so on small motor, pump, tractor, automobile, metallurgy, textile machinery and other medium speed, medium load rolling and plain bearings.
