Application of Molybdenum Disulfide:

Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and high pressure. It is also diamagnetic, 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.

It is also known as the "king of advanced solid lubricants". Molybdenum disulfide is a solid powder made from natural molybdenum concentrate after chemical purification and then changing the molecular structure. This product is black with a slight silver gray, metallic luster, slippery to the touch, and insoluble in water. The product has the advantages of good dispersibility and non-sticking. It can be added to various greases to form a non-sticky 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 high-load mechanical working conditions to extend equipment life.

The main function of molybdenum disulfide used in friction materials is to reduce friction at low temperature, increase friction at high temperature, and have a small loss on ignition. It is volatile in friction materials.

Anti-friction: Molybdenum disulfide processed by supersonic jet pulverization has a particle size of 325-2500 mesh, a microparticle hardness of 1-1.5, and a friction coefficient of 0.05-0.1, so it can reduce friction when used in friction materials;

Increase friction: Molybdenum disulfide is not conductive, and there are copolymers of molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide. When the temperature of the friction material rises sharply due to friction, the molybdenum trioxide particles in the copolymer expand as the temperature rises to increase the friction;

Anti-oxidation: Molybdenum disulfide is obtained through chemical purification and comprehensive reaction. Its PH value is 7-8, which is slightly alkaline. It covers the surface of the friction material to protect other materials from oxidation, especially to make other materials not easy to fall off, and enhance the adhesion.
