Simple identification method of stainless steel bearing grease

1. Soap base in the identification of the daub on the copper grease, and then put a hot water, if the grease and water, water does not change color, that is the calcium base grease, lithium base grease or barium base fat; If the grease quickly dissolve in water, into the milk, translucent milky solution is sodium based grease; Grease, although can dissolve in water, dissolving speed is very slow, that is sodium calcium base grease. 2. Fiber destructive to identify the network structure of copper coated with grease into the test tube with water and constantly rotating, without oil, shows that the organizational structure of the grease is normal, if there is oil bead float on the surface of the water, that the fiber network structure of the grease has been damaged, lost adhesion, cannot continue to use. The main reason is improper safekeeping, subjected to vibration and long storage. 3. Inspection of mechanical impurities, take a small amount of grease to twist with finger pressure by judgment without impurities; Color the grease on the transparent glass, coating thickness of about O. 5 mm, you can observe without mechanical impurities in the light.
