NOVELTY - This model discloses a self-lubricating seal containing graphene components, which is mainly used to improve the performance of traditional rubber seals; it can be more effectively used in piston seals, shaft seals, shock-absorbing seals, electromagnetic Valve seals, O-rings, special-shaped rings...and other parts that are in contact with metal during movement. It mainly uses the characteristics of high strength, high lubrication and low friction coefficient of the graphene components effectively dispersed in the rubber ingredients; the graphene content is from 0.1PHR to 20PHR, adjusted according to production needs, and determined by the friction coefficient and lubrication of the parts It depends on the degree. The processed seals can greatly improve the lubricity of the seals, reduce the friction and wear of the seals in motion, and can operate stably for a long time, extending pneumatic, oil pressure, or linear, rotating... etc. The life of each component and reduce the energy consumption of work.
