Tungsten Disulfide Powder
Tungsten disulfide is an inorganic compound with gray black appearance. The molecular formula is WS2. The molecular weight is 247.97. Tungsten disulfide has semiconductivity and diamagnetism.
The crystal structure of WS2 is a typical hexagonal layered structure. Each layer is composed of two hexagonal sulfur atoms sandwiched with a layer of metal tungsten atoms, and the sulfur atoms and tungsten atoms form a triangular cone. The sulfur atoms and tungsten atoms in each layer are connected by strong covalent bonds, and the layers are combined by relatively weak van der Waals force. This kind of connection makes the layers have strong sliding property, and sulfur atoms are easy to physically or chemically adsorb with most metals to form transfer film. Friction mostly occurs between lubricating film and transfer film. Therefore, although there is friction, wear does not necessarily occur, The damaged part of the film can be repaired by moving the lubricating film adhered to the lubricated material and the WS2 debris accumulated on both sides of the friction part.
We mainly provide nano tungsten disulfide powder, micro ultra-fine tungsten disulfide powder.
Tungsten Disulfide Powder Application
Our tungsten disulfide powder has high purity, high natural packing density and narrow particle size distribution. It is suitable for the following occasions:
1. Adding 3-5% tungsten disulfide powder into the brush can effectively prolong the service life of the brush by 20% - 40%; It is especially suitable for brushes for electric tools and household appliances with remarkable effect;
2. Adding 5-10% tungsten disulfide powder into the graphite mechanical seal ring can effectively reduce the wear rate and prolong the service life by more than 30%;
3. Tungsten disulfide powder can also be used as mold release agent, ball bearing and roller bearing lubricant, industrial gear and bearing lubricant;
4. Tungsten disulfide powder can be used in engine and transmission system components, air vibrator, electric connector of pneumatic motor, circuit breakers and switches (additives for super electrical contact materials), motor, press and adjustable resistor, pilot valve, chain saw, etc;
5. Tungsten disulfide powder can also be used in rubber gaskets and O-rings, satellite and aircraft parts, high vacuum application products, low temperature pump seal ring, etc.
