Introduce the use of molybdenum disulfide lubricant products

Molybdenum disulfide lubricant product use:

(1) Widely used in automobile industry and machinery industry, can be used as a good lubricating material.

(2) Under high temperature, low temperature, high load, high speed, chemical corrosion and modern ultra-vacuum conditions, it has excellent lubricity for equipment.

(3) Addition to lubricating oil, grease, polytetrafluoroethylene, nylon, paraffin, stearic acid can improve the lubrication and reduce friction.

(4) Extend the lubrication cycle, reduce costs, improve working conditions, and can also be used as a non-ferrous metal release agent and forging die lubricant.

(5) Improve the running-in condition, prevent surface damage, and prevent cold welding, such as stainless steel welding.

(6) When using threaded connections, ensure a better connection.

(7) Compatible with certain volatile solvents and sprayable metal surfaces or added engineering plastics to make lubricating originals.

(8) Such products can be directly used in electronics, spraying, plating, hardware, screws and other industries.

Molybdenum concentrate can be prepared by using hydrochloric acid and hydrofluoric acid under direct steam heating, repeated stirring treatment, washing with hot water, centrifuging, drying, and pulverizing. Hydrogen sulfide gas is passed into the ammonium molybdate solution to generate ammonium thiomolybdate. Add hydrochloric acid to transform into molybdenum trisulfide precipitation, and then centrifuge, wash, dry, and crush. Desulfurization can be obtained by heating to 950 ° C. Molybdenum disulfide and alkyl lithium react under control to form an intercalation compound (interlayer compound) LixMoS2. If reacted with butyllithium, the product is LiMoS2.

Molybdenum disulfide has a high content of active sulfur and is liable to cause corrosion of copper. It is discussed in many books and papers on lubricant additives. In addition, when the parts made of copper and its alloy need to be lubricated, it is not impossible to choose a molybdenum disulfide-containing lubricating product, but it is also necessary to add a copper corrosion inhibitor.
