WS2 coated bolts/screws, also known as tungsten disulfide solid lubricating film, are formed by mixing organic binders (epoxy resin) or inorganic binders (sodium silicate, etc.) with materials such as tungsten disulfide powder to form a film-forming agent, and then spraying or brushing to form a solid film with self-lubricating properties on the friction surface.
The friction coefficient of WS2 coated bolts/screws is relatively low, with a dynamic friction coefficient of 0.03 and a static friction coefficient of 0.07, which helps to avoid carbon accumulation and can solve related technical problems. For example, in injection molding production, it is easy to cause wear and bite of the grinding tool top bar and sliding block due to the inability to refuel (polluting the product due to refueling regret), such as electronic communication products, pharmaceutical and cosmetic packaging products, car lamps, household appliance panel decorations, etc; It can withstand high temperatures of 650 degrees Celsius and maintain oil-free lubrication performance even at low temperatures of -270 degrees Celsius. It is compatible with most oils and greases and maintains a fluid dynamic layer, preventing scratches, abrasions, micro movements, or cold welding of components or machine parts. It also helps reduce maintenance issues, expensive component replacements, downtime, and other problems, thereby extending the service life of the grinding tool.
WS2 coated bolts/screws are used in high-temperature and high-speed bearings, gears, chains, engine pistons, piston rings, etc. for aerospace vehicles, launch vehicles, airplanes, etc; Standard parts: bolts, nuts, screws, threaded rods, spline shafts, washers, washers, etc; And automotive components: automotive/diesel engine bearings, cylinder gaskets, pistons, piston rings, thrust plates, springs, locks, shafts, pins, air compressor slant plates, car lamp grinding tools, mirror grinding tools, ejector pins, inserts, and stamped parts.
