Application range of molybdenum disulfide powder

Molybdenum disulfide powder products have good chemical and thermal stability. It is soluble in aqua regia and concentrated sulfuric acid, insoluble in water and dilute acid, does not cause chemical reaction with general metal surfaces, and does not attack rubber materials. It can be used for handling and storage of spare parts. The smooth maintenance can form an efficient adhesion dry smooth film, which is a special information for reducing wear and many problems in friction technology.

Application category

1 Application in smoothing agent: Not only can it increase the big bite-free load of smooth oil, but also reduce the wear and improve the conflict function of data. The mechanism is that nano-MoS2 is more prone to conflict chemical reactions than ordinary MoS2. It forms a smooth film rich in sulfur and molybdenum, and plays an anti-wear function. The mechanism of molybdenum disulfide to reduce conflict and wear is completely different from that of smooth grease. It can continue to maintain its excellent anti-collision wear properties under high vacuum. Its main application is For difficult-to-maintain equipment, such as space vehicles, satellites, and military fields;

2 Application in composite materials: PS / MoS2 nano-composite materials will use molybdenum disulfide with a certain conductivity as a conductive filler to improve the electrical function of polystyrene, so that it has a certain antistatic ability but will not change it. Insulation

3 Compared with general molybdenum disulfide, the surface atomic number of nano-molybdenum disulfide increases significantly, forming more sulfur vacancies, which makes its catalytic activity and selectivity higher. It can be used as a highly active hydrogenation catalyst for heavy oil conversion and fuel refining. Nano-molybdenum disulfide is used as a catalyst in the process of carbon monoxide methanation, and has high selectivity and reactivity. Nano-molybdenum disulfide is a catalyst for coal liquefaction.

Packaging and storage

Molybdenum disulfide powder is an inert gas antistatic package. It should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time.
