Advantages of molybdenum disulfide powder

Molybdenum disulfide is a solid powder made by changing the molecular structure of natural molybdenum concentrate powder after chemical purification.

Molybdenum disulfide lubricant is made of ultra-fine molybdenum disulfide as the base material, which can form a layer of fast-drying molybdenum disulfide spray lubricant on the metal surface.

Molybdenum disulfide powder is black with silvery gray, metallic luster, it feels slippery when touched, and it is insoluble in water. The product has the advantages of good dispersibility and non-adhesion. It can be added to various greases to form a non-adhesive colloid state, which can increase the lubricity and extreme pressure of the grease. It is also suitable for high-temperature, high-pressure, high-speed, high-load mechanical working conditions, extending the life of equipment.

The main function of molybdenum disulfide for friction materials is to reduce friction at low temperature and increase friction at high temperature. The burning loss is small and it is volatile in the friction material.

Anti-friction: The particle size of molybdenum disulfide processed by supersonic jet milling reaches 325-2500 mesh, micro-particle hardness is 1-1.5, and friction coefficient is 0.05-0.1, so it can be used to reduce friction in friction materials;

Antifriction: 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, which plays a role in increasing friction;

Antioxidation: 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, can protect other materials, prevent them from being oxidized, especially makes other materials difficult to fall off, and enhances the adhesion.

Performance characteristics

While cleaning the metal, fill all the pores, pits, scratches and other micro-hole defects on the metal surface, which greatly reduces the friction under load conditions;

Free of grease and graphite. It is very effective as a pre-lubricating coating for high-temperature mechanical devices, and can be used as an assembly lubricant, a lubricant for the close contact of a punch, and other high-pressure parts;

Excellent metal surface adhesion and rust resistance, which can prevent abrasion, abrasion and sintering between metals;

Excellent water scour resistance and corrosion resistance, low friction coefficient, wide temperature range
