Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and pressure. It is also diamagnetic, and can be used as a linear photoconductor and a semiconductor showing P-type or N-type conductive properties, with rectification and energy exchange roles. Molybdenum disulfide can also be used as a catalyst for 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 powder after chemical purification and molecular structure change. This product color black slightly silver gray, metallic luster, touch with a slippery sense, insoluble in water. The product has the advantages of good dispersion and non-bonding, and can be added to various oils to form a colloid state that is never bonded, which can increase the lubricity and extreme pressure of the oil. It is also suitable for high temperature, high pressure, high speed and high load mechanical working conditions to extend the life of the equipment.
Application Of Molybdenum Disulfide
The main function of molybdenum disulfide used in friction materials is to reduce friction at low temperature, increase friction at high temperature, small firing loss, and volatile in friction materials.
Anti-friction: Molybdenum disulfide formed by supersonic airflow grinding processing particle size of 325-2500 mesh, microparticle hardness 1-1.5, friction coefficient of 0.05-0.1, so it can be used in friction materials can play a role in anti-friction;
Increasing friction: Molybdenum disulfide is not conductive, and there are copolymers of molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide. When the friction material temperature rises sharply due to friction, the molybdenum trioxide particles in the copolymer expand with the temperature rise, which plays a role in increasing friction.
Anti-oxidation: molybdenum disulfide is obtained through a comprehensive reaction of chemical purification, and its PH value is 7-8, slightly alkaline. It covers the surface of the friction material, can protect other materials, prevent them from being oxidized, especially so that other materials are not easy to fall off, and the adhesion is enhanced;
Fineness: 325-2500 mesh;
SIO2:0;
PH value :7-8;
Density :4.8-5.0g/cm3;
Hardness :1-1.5;
Firing loss :18-22%;
Friction coefficient :0.05-0.09.
In addition, molybdenum disulfide can also become a new material for making transistors. Compared with graphene, which is also a two-dimensional material, molybdenum disulfide has a band gap of 1.8eV, while graphene does not have a band gap, so molybdenum disulfide may have a broad application space in the field of nanotransistors. Moreover, the electron mobility of the single layer molybdenum disulfide transistor can reach about 500 cm^2/(V·s), and the current switching rate can reach 1×10^8
