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 in the presence of heat 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-lipid 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, when parts of copper or their alloy manufacturing require lubrication it is not necessary that lubrication products contain molybdenum disulfide. Instead, they must be combined with an anti-copper 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 products, as well as synthetic lubricants. It has good chemical stability and thermal stability. It does not react to general metal surfaces. 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. Molybdenum dioxide is a lubricant that has excellent compressive strength, wear resistance, excellent adhesion (0.03-10.08), and film structure characteristics. It can also be used under high temperatures (1200), low temperatures (-190), high speeds, high pressure, and ultra-low temperatures. At 400, molybdenum dioxide begins to oxidize and becomes molybdenumtrioxide. It rapidly oxidizes above 540 to become molybdenum trimoxide. It was sublimated to 450 in an atmosphere of inertia, and at 1370 it was decomposed to molybdenum trioxide and sulfur. By controlled reaction with alkyl-lithium, molybdenum sulfide and chlorine gas heat reaction to make molybdenum penichloride were achieved. 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, Cu, Ca and other impurities from molybdenite concentration after a certain physical and chemical activity and refines it to make 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. However, the purity and purification of nano MoS2 made by the natural process is low. If the temperature drops below 400 degrees it is recommended that you use a low-cost MoS2 for normal conditions. 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. At the moment, dry film lubricant can be used to lubricate bearings, molds, and many 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 makes it difficult to grease or supplement equipment.
3. Lubricating film-forming glue for wheels, rails and gear . The film-forming powder is widely used for lubricating the gears on locomotive drive shafts, cranes or steel rolling equipment. It can also be used to grease large machinery such as mines. You can extend the life of rail by applying film-forming paste to rail and rim. The life expectancy of the rim is 7 times longer and electricity (or fuel) can be saved by around 7%.
