What is the difference between 3# general lithium grease and 3# molybdenum disulfide general lithium grease, which should be paid attention to in application?
January 27, 2022
3# general lithium grease has excellent mechanical stability, colloidal stability, oxidative stability and shear resistance, high and low temperature resistance and good water resistance. It is widely used in the lubrication of friction parts such as rolling bearings, sliding bearings and automobile chassis of various mechanical equipment. 3# lithium molybdenum disulfide grease is a multi-effect long-life grease with good mechanical stability, rust resistance and oxidation stability, colloidal stability, oxidation stability, thermal stability, water resistance and extreme pressure. Anti-wear properties. Lithium molybdenum disulfide grease is suitable for the lubrication of gears and bearings of various heavy-duty machinery and equipment such as rolling steel machinery, construction machinery, heavy lifting machinery, construction machinery, etc. Molybdenum disulfide lithium grease contains molybdenum disulfide (a solid lubricant) while ordinary lithium grease does not. Molybdenum disulfide No. 3 is generally black. No. 3 molybdenum disulfide can still play a lubricating role after the non-solid lubricant volatilizes at high temperature. It is made of lithium base grease and adding molybdenum disulfide powder. It has better water resistance, better mechanical stability and pressure resistance. The scope of use is the same as that of general-purpose lithium-based grease, and it is mainly used for the lubrication of heavy-duty machinery.
General lithium grease application should pay attention to: 1. Molybdenum disulfide has good water resistance, good mechanical stability and pressure resistance, and is mainly used for the lubrication of heavy-duty machinery. 2. Molybdenum disulfide has a certain corrosive effect on copper and its alloys. It is not suitable for copper pipes to be transported, which will cause pipeline blockages and cause oil shortage accidents. 3. It is not suitable for worm gear and worm gear made of copper alloy, which will lead to broken teeth due to corrosion. 4. It is not suitable for rolling bearings with copper alloy cages, which will cause the cage to break due to corrosion. 5. When parts made of copper and its alloys need to be lubricated, it is best not to use lubricating products containing molybdenum disulfide. This is a lesson learned from many equipment accidents.
