Description
Technical field
The present invention relates to sealing ring field, particularly a kind of O-ring sizing material and preparation method thereof.
Background technology
O-ring seal is applied in the various plant equipment, in defined temperature, pressure and different liquid and
In gas medium, sealed under static or motion state.In lathe, ship, automobile, aerospace equipment, metallurgical machine
Tool, chemical machinery, engineering machinery, building machinery, mining machinery, petroleum machinery, plastics machinery, agricultural machinery and all kinds of instrument
On instruments and meters, various types of potted components are widely applied.O-ring seal is mainly used in static seal and reciprocating movement sealing.
During for rotary movement seal, low speed rotary seal is only limitted to.O-ring seal is typically mounted at cylindrical or inner circle upper section
To be sealed in the groove of rectangle.O-ring seal still plays good close in environment such as oil resistant, soda acid, mill, chemical erosions
Envelope, cushioning effect.Therefore, O-ring seal is most popular a kind of seal in hydraulic and pneumatic transmission system.
Axle is mainly used on piston or piston rod with O-ring seal, its require compressive resistance it is big, with self lubricity
The wide requirement of energy, operating temperature.
