Tungsten Disulfide Lubricant Advantages

Tungsten disulfide has similar lubricating properties with graphite, is widely used as a lubricant. And tungsten disulfide as a lubricant performance is better than molybdenum disulfide, mainly due to it properties which is low friction coefficient(0.03), high resistance to extreme pressure and oxidation resistance, namely, tungsten disulfide at 450 ℃ in the air begins to decompose, until 650 ℃ completely decomposed. On the other hand, at1100 ℃ in the vacuum it begins to decompose, until 2000 ℃ completely decomposed. This performance is conducive tungsten disulfide apply in high-temperature, high pressure, high speed, high load, as well as in chemical active media device operation.
Meanwhile tungsten disulfide on the metal surface has a good adsorption capacity can be added to make the original lubrication in engineering plastics or it can mix with volatile solvent sprayed on the metal surface, to improve the life of mold in press forging and workpiece surface finish.
Tungsten disulfide also can mix with the oil, fat oil to form tungsten disulfide, tungsten disulfide grease, wax and other tungsten disulfide solid lubricating block and lubricating film.
