Introduction to Molybdenum Disulfide Pulver
Molybdenum disulfide
is a type of inorganic. MoS2, which is molybdenite’s main component, has the chemical formula MoS2. It is a solid black powder with a metallic luster. It has a melting temperature of 2375, a density 4.80g/cm3 (14), Mohs hardness 1.0 1.5.
Molybdenum disulfide decomposes at 1370, and then to molybdenum metallic and sulfur at 1600. Molybdenum disulfide can be oxidized by heating it in air at 315. Molybdenum sulfide can’t be dissolved in water, dilute or concentrated sulfuric acids. At 400, slow oxidation takes place and molybdenum dioxide forms.
Molybdenum disulfide Can be heated to produce molybdenum pythloride by reacting with chlorine gas
Molybdenum disulfide reacts to alkyl-lithium under control to create an embedded compound (intercalated compounds) LixMoS2. It will react with butyllithium and form LiMoS2.
Molybdenum disulfide Copper has a high level of active sulfur. It is easy to cause copper to corrosion. This topic has been covered in many papers and books on lubricant ingredients. Additionally, it is not necessary that lubrication products contain molybdenum disulfide. But, you must also add an anti-copper agent to lubricate copper alloy parts.
Molybdenum Disulfide Pulp Powder’s Physical Chemistry
Molybdenum disulfide It is insoluble with water and dilute acids. It can be corroded easily by concentrated sulfuric, concentrated nitric, boiling concentrated chloric acid, aqua regia or pure oxygen, fluorine, or chlorine. It is insoluble with other bases, solvents and petroleum, as well as synthetic lubricants. It is non-magnetic and has semiconductor properties. Molybdenum dioxide mo-S edges are quite numerous, easy to peel among layers, with good anisotropy. They have strong adhesion and can adhere to any metal surface. The lubricant molybdenum dioxide is high in compressive strength, wear resistance, excellent adhesion (0.03-10.08), film structures characteristics, the stable film at high pressure. It can also lubricate well under high temperatures (1200), low temperatures (-190), high speeds, high pressure, ultra low temperature and high vacuum conditions. At 400, molybdenum dioxide begins to oxidize and becomes molybdenum triglyceride. It oxidizes rapidly to molybdenum triglyceride above 540. It was sublimated to 450 in an atmosphere of inertia, and at 1370 it was decomposed to molybdenum trioxide and sulfur. By controlled reaction of alkyl lithium and molybdenum dioxide, it was formed into molybdenum penichloride. Low toxicity.
Molybdenum Disulfide Pulver Preparation Methods
Natural law
Molybdenum dioxide has many applications and great properties. Therefore, nano-mos2 preparation and application have been extensively studied both at home and abroad.
MoS2 can be prepared using the natural molybdenite concentration purification method. This method removes acid insoluble matter, SiO2, Fe Cu, Ca, Cu, Cu, Pb, and other impurities from molybdenite concentration after a certain physical and chemical activity. Next, refine the process to create nano-mos2. This is how the Us Climax Molybdenum firm produces MoS2. This method is suitable for the production of lubricants because it preserves the MoS2 crystal form. The natural method produces nano MoS2 with a low purity, so further refinement of the purification technology is needed. If the temperature drops below 400 degrees it is best to use a low-cost MoS2 for ordinary environments. It is not possible to lubricate the MoS2 with a lower lubrication level than 1300.
Chemical synthesis
The synthesis process can produce sulfide in high purity, with few impurities and fine particles, and can meet different functional requirements. This is why the synthesis procedure to make nano sulfide was so important. There are many ways to make nano-MOS2, such a thermal decomposition method for ammonium tetrathiomolybdate and hydrogen sulfide. Two preparation methods can be used to make nano-mos2: The tungsten source/molybdenum can be directly mixed with the source of sulfur, or the tungsten and molybdenum can be combined with sulfur to create the precursor body.
Molybdenum Disulfide Powder – Applications
1. Dry-film lubricants . Molybdenum-disulfide is used in most dry film lubricants (epoxy resin type EM-1 dry film) except where black fillers have not been specified. Molybdenum-disulfide dry-film lubricants that are most commonly used are the United States military dry films MIL L-3987 and MIL L-23398. Dry film lubricant can be used to lubricate bearings, gears, and other civil products.
2. Lubricants . Molybdenum sulfide ointment generally is added to oil and fat with a mole fraction of about 4.4%. It has been used successfully in the fields of metallurgy and steel rolling, as well as mining machinery and equipment for coal mining. Some high temperature, open air, field, and tunnel application equipment make it difficult for grease to be lubricated or added to.
3. Lubricating film-forming glue for wheels, rails and gear . The film-forming powder is widely used for lubrication of the gears on locomotive drive shafts, cranes or steel rolling equipment. It can also be used for large equipment like mine. You can extend the life of rail by applying film-forming paste to rail and rim. Rim life is extended 7 times and electricity or fuel is saved approximately 7%.
