What Is Molybdenum Disulfide?
Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid, generally do not dissolve in acid, alkali, organic solvents, but soluble in hot sulfuric acid. 400 ° C occurs slowly oxidized to produce molybdenum trioxide.
It is important that the solid lubricant, especially suitable for high temperature and pressure. It also has anti-magnetic, and the display can be used as the linear photoconductor P-type or N-type conductivity semiconductor, a rectifying effect and transducers. Molybdenum disulfide is also used as a catalyst for the dehydrogenation of hydrocarbons complex. It is also known as "Advanced solid lubricant king."
Molybdenum disulfide is a natural molybdenum powder by chemical changes in the molecular structure of the purified and made of a solid powder. The product color black slightly silver, metallic luster, touch of creamy, insoluble in water. Products with good dispersion, not bonded advantages, can be added in a variety of oils, the formation of colloidal never bonded state, can increase oil lubricity and extreme pressure properties. Also suitable for high temperature, high pressure, high speed and high load mechanical working condition, extend equipment life.
Molybdenum disulfide applications
Main function is used for friction material friction at low temperatures, high temperatures increase friction, LOI small, friction materials volatile;
Less friction: the supersonic jet grinding processing of molybdenum disulfide reached 325-2500 mesh size, micro particle hardness 1-1.5 0.05-0.1 friction coefficient, friction materials for it can play the role of friction;
Increased friction: not conductive molybdenum disulfide, molybdenum disulfide exist, molybdenum trisulfide, molybdenum trioxide copolymer. When the friction material due to friction and rapid temperature rises, the copolymer particles of molybdenum trioxide with heating and expansion, played a role in increasing friction;
Oxidation: Molybdenum disulfide is derived through chemical purification integrated response, the PH value is 7-8, slightly alkaline. It covers the surface of the friction material, to protect other materials to prevent them from being oxidized, in particular, easy to fall off so that other materials, adhesion force enhancement;
Fineness: 325 mesh -2500 mesh; SIO2: 0; PH value 7-8; Density :4.8-5 .0g/cm3; hardness :1-1 .5; LOI :18-22%; friction coefficient 0.05 - 0.09 .
