Graphite for Mechanical Usage
Features
Due to the characters such as lubrication,heat resistance,chemical stability,etc,the Mechanical graphite materials are widely used in high temperature,acid,alkali solution,organic solvents and other fields.Our company has the corresponding high-quslity graphite materials ,can meet the needs of customers for need preparation.

Self lubrication
The layered crystal structure of graphite material enables its self lubrication,under non-lubricating status,graphite have characteristics such as smaller friction coefficient,lower abrasiveness when compared with other materials.

High temperature resistance
Temperature changes have no significant affection on graphite's mechanical strength and self lubrication.

Chemical Stability
Apart from some inorganic drugs(strong acid),graphite has the capability of resisting chemical reaction.

Heat shock resistance
Compared with the metal materials,graphite has character such as small
thermal expansion rate and excellent thermal conductivity,therefore,when the rapid temperature change occurs,the material has no obvious change.

Conductive to Lightweight Design
Compared with the metal material,graphite have a smaller density,so it is easy to light the weight of the mechanic and decrease the vibration noise.


Application
Graphite materials used for mechanical automotive,electrical,petrochemical and machinery industries,to provide the necessary carbon graphite components;mainly used in dry rotary vane
compressors and vacuum pumps;rotary compressor,screw compressor,fan,and the radial axis with sealing ring and sealing rings;oil-free piston compressor sealed with graphite piston and rod guide ring;mechanical seals,axial end with ball valve seals;liquid medium transmission with graphite bearings,seals,combination seals,rotary vane,rotor and hub and so on.
