Graphite cylinder

Carbon graphite products for machinery are indispensable and important parts in modern high-efficiency machinery. According to different process conditions and friction materials, various carbons of different materials and impregnated with different materials can be used - graphite sealing rings, graphite Expanding rings, vanes, graphite bearings, bushings and gaskets. It has been successfully used in low temperature, high temperature, vacuum and high pressure, various rotation speeds and various corrosive, flammable, explosive and toxic media. It is an ideal tool for use in dry grinding, semi-dry grinding and liquid conditions. components and materials.
Graphite is the most widely used material in the friction pair of rotary joints. Graphite materials are made of powders of various carbon raw materials (coke, carbon black, coal, graphite). Compared with other non-metallic materials, graphite has excellent corrosion resistance. Performance, in addition to being durable to strong oxidizing media (such as aqua regia, nitric acid, chromic acid with a concentration of more than 60%, potassium dichromate, potassium permanganate, etc., and 10% fluorine, 100% bromine, ammonia water, etc.), it can also withstand Corrosion of any concentration of acid, alkali, salt solution and all organic compounds. Graphite materials have particularly good self-lubricating properties, and the coefficient of friction is quite large. When graphite and metal are rubbed against each other, the friction coefficient is 0.04-0.05, which shows that the wear rate is not large. Graphite has high thermal conductivity [80~180Cal/(m.h. ℃)] and electrical conductivity (5×10-4~60×10-4Ω.cm), and it is reducible below 3000 ℃. High stability and low linear expansion coefficient.
