Nano Tungsten disulfide flakes 70nm For Lubrication Coating and Catalysis

1, nano tungsten disulfide (referred to as WS2) is mainly used as a petroleum catalyst: it can be used as a hydrodesulfurization catalyst, but also used as a catalyst for polymerization, reforming, hydration, dehydration and hydroxylation processes, and because of its good cracking performance, stable and reliable catalytic activity, long service life and other characteristics, it is very popular with petroleum refineries.

2. In the preparation technology of inorganic functional materials, nano WS2 is a new type of efficient catalyst. Due to the formation of a new compound with sandwich structure, nano WS2 can be made into a single molecular layer two-dimensional material, and can be restacked into a granular new material with a very large internal space "floor house structure" as required, and intercalation substances can be added during the restacking process. Make it a catalyst or sensitive display and superconducting material, its huge internal surface area is easy to include accelerators, become a new type of efficient catalyst, Japan Nagoya Industrial Research Institute found that nano WS2Chemicalbook has a great catalytic effect in the process of CO2 conversion to CO, which will promote the development of carbon cycle technology, Paving the way to reverse global warming trends.

3, WS2 can be used as solid lubricant, dry film lubricant, self-lubricating composite materials: nano WS2 is the best solid lubricant, its friction factor is 0.01 ~ 0.03, compressive strength up to 2100MPa, with acid and alkali corrosion resistance, good load resistance, non-toxic and harmless, wide use temperature, long lubrication life, low friction factor advantages. In recent years, the ultra-low friction and wear displayed by solid lubricant hollow fullerene nano WS2 has attracted much attention. For example, in the 1980s, the United States used nano WS2 particles to spray on the metal surface to form a WS2 lubricating dry film to greatly reduce the friction factor and improve the life of the mold. 4, nano tungsten disulfide is a very important additive for the manufacture of high-performance lubricants.
