Solid graphite lubricant is needed in some mechanical equipment and mechanical parts which can not use lubricating oil and grease. Solid graphite lubricant made of graphite powder can overcome the high temperature, high pressure and high friction caused by mechanical operation. In the maintenance of mechanical equipment, solid graphite lubricant can make graphite powder adhere to the list of mechanical parts. Surface, reduce friction, regular use, inspection and maintenance of machinery, will prolong the service life of mechanical parts, graphite powder used in lubricants, can play its role of lubrication, high temperature resistance, wear resistance, corrosion resistance.
