Description
Technical field
The invention belongs to tire manufacturing arts, are specifically a kind of high thermal conductive tyre sulfurized capsule.
Background technology
Tyre capsule is for manufacturing the indispensable consumable part of tire.In the sulfidation of tire, inside tyre capsule
Compressed gas or superheated water are filled, tire sealant embryogenesis internal pressure vulcanized tyre is strutted to uphold.Compressed gas is usually nitrogen,
Superheated water is the hot water by deoxygenation, and such technique sets the oxidation for avoiding tyre capsule as far as possible, so as to increase tire sealant
The service life of capsule.
One good capsule need to possess following functions：The impermeability of air/gas/steam/water etc., heat transmitting, height
Pressure stability makes to reach the height combination of tire material, is embodied in the circulation change of water/nitrogen/steam pressure extruding and true
The anti-growth property of the high flexibility in deformation, height in Altitude, this may result in flexural deformation problem so as to influence
Tire quality, high resistance ozone/oxygen/steam/heat degradation property.Currently on the market common tyre capsule cannot reach more than will
It asks, and has been difficult in heat-transfer rate and service life to meet the needs of market.
