Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and high pressure. It is also diamagnetic and can be used as a linear photoconductor and a semiconductor showing P-type or N-type conductivity, and has the functions of rectification and energy conversion. Molybdenum disulfide can also be used as a catalyst for the dehydrogenation of complex hydrocarbons.
Anti-oxidation: Molybdenum disulfide is obtained through chemical purification and comprehensive reaction, and its pH value is 7-8, which is slightly alkaline. It covers the surface of the friction material, which can protect other materials and prevent them from being oxidized, especially to make other materials not easy to fall off and enhance the adhesion;

It is also known as the "King of Advanced Solid Lubricants". Molybdenum disulfide is a solid powder made of natural molybdenum concentrate powder after chemical purification and changing the molecular structure. This product is black and slightly silver-gray, with metallic luster, smooth to the touch, and insoluble in water. The product has the advantages of good dispersibility and non-adhesion. It can be added to various greases to form a colloidal state with no adhesion, which can increase the lubricity and extreme pressure of the grease. It is also suitable for mechanical working conditions of high temperature, high pressure, high speed and high load, so as to prolong the life of the equipment.
The main function of molybdenum disulfide used in friction materials is to reduce friction at low temperature and increase friction at high temperature, with small loss on ignition and volatile in friction materials.
Friction reduction: The particle size of molybdenum disulfide processed by supersonic jet pulverization reaches 325-2500 mesh, the hardness of micro-particles is 1-1.5, and the friction coefficient is 0.05-0.1, so it can play a role in reducing friction when used in friction materials;
Friction increase: 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 as the temperature increases, and play a role in increasing friction;
