Overview of MoS2 MoS2
Molybdenum disulfide is an inorganic substance with the chemical formula MoS2, which is the main component of molybdenite. Black solid powder with metallic luster. The melting point is 2375°C, the density is 4.80g/cm³ (14°C), and the Mohs hardness is 1.0 to 1.5.
The four most commonly used solid lubricants are
1. Graphite can be used as a dry powder for splash lubrication. Can be used as an additive in the manufacture of water and oil. It can also be combined with other materials to form composites for lubrication in transmissions. It can also be used in conductive conditions - wear parts.
2. Molybdenum disulfide MoS2, known as "the king of high-grade solid lubricants". MoS2 can be added to various greases to form a non-viscous colloidal state that increases lubricity and extreme pressure. MoS2 is also suitable for high temperature, high pressure, high speed, high load mechanical conditions to prolong equipment life.
3. Tungsten disulfide WS2 has better performance than molybdenum disulfide, low friction coefficient and high compressive strength. WS2 can be used for high temperature, high pressure, high speed, high load, and equipment operating in chemically active media.
4. Boron nitride BN, known as white graphene, can be used in spacecraft.
Application of molybdenum disulfide
Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and high pressure. It is also diamagnetic and can be used as linear photoconductors and semiconductors showing P-type or N-type conductivity, with rectification and energy conversion. Molybdenum disulfide can also be used as a catalyst for complex hydrocarbon dehydrogenation.
It is also known as the "King of Advanced Solid Lubricants". Molybdenum disulfide is a solid powder made of natural molybdenum concentrate after chemical purification and changing the molecular structure. This product is black, slightly silver-gray, with metallic luster, smooth hand feeling, insoluble in water. This product has the advantages of good dispersion and non-stick. It can be added to various greases to form a non-stick colloidal state, which can increase the lubricity and extreme pressure of the grease. It is also suitable for high temperature, high pressure, high speed and the main function of molybdenum disulfide used in friction materials is to reduce friction at low temperature, increase friction at high temperature, and small loss on ignition. Volatile in friction materials.
Friction reduction: The particle size of molybdenum disulfide processed by supersonic jet pulverization is 325-2500 mesh, the particle hardness is 1-1.5, and the friction coefficient is 0.05-0.1, which can reduce friction when used for friction materials;
Increase friction: Molybdenum disulfide is non-conductive, and there are copolymers of molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide. When the temperature of the friction material increases sharply due to friction, the molybdenum trioxide particles in the copolymer expand with the increase of temperature and increase the friction force;
Antioxidation: Molybdenum disulfide is obtained through chemical purification and comprehensive reaction, with a pH value of 7-8, slightly alkaline, covering the surface of friction materials to protect other materials from being oxidized, especially to make other materials not easy to fall off, enhance adhesion;
