Introduction to Molybdenum Disulfide Pulver
Molybdenum disulfide
is a type of inorganic. MoS2, the main ingredient of molybdenite, is its chemical formula. 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 is first oxidized at 315 when it is heated in air. 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 You can heat it to react with chlorine gas and form molybdenum pytachloride
Molybdenum disulfide reacts to alkyl-lipid under control to create an embedded compound (intercalated compounds) LixMoS2. If it reacts to butyllithium, then the product is 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, it is important to include an anti-copper corrosion agent.
Molybdenum Disulfide Pulp Powder’s Physical Chemistry
Molybdenum disulfide It is insoluble with water and dilute acids. It can also be corroded if heated concentrated hydrochloric, concentrated sulfuric, concentrated nitric, boiling concentrated chloric acid, aqua regia or pure oxygen, fluorine, or chlorine are used. 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, and have good anisotropy. They have strong adhesion to metal 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, and stable under high pressure. It can also be used under high temperatures (1200), low temperatures (-190), high speeds, high pressure, ultralow temperature, and high vacuum. 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, then decomposed at 1370. At 1600, it was decomposed into molybdenum et 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, 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 capable of maintaining the MoS2 crystal form and high lubrication performances, making it suitable for the production of lubricants. However, the purity and purification of the natural nano MoS2 is low. 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 with fine particles. This can be used to produce sulfide having different functional requirements. There are many ways to make nano-MOS2, including the thermal decomposition technique of ammonium triathiomolybdate and hydrogen sulfide reduction methods, high-energy ball grinding method, carbon nanotubes space-limiting method, hydrothermal synthesizing method, and high-energy physical or chemical means. 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. Then, the precursor can be reduced or decomposed to MoS2 with the appropriate methods.
Molybdenum Disulfide Powder – Applications
1. Dry-film lubricants . Molybdenum disulfide can be used as a lubricant in nearly all dry film lubricants. 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 . Film-forming paste is widely used for lubricating the gears on locomotive drive shafts, cranes or steel rolling equipment. It can also be used on 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 petrol) is reduced by around 7%
