Type B curing bladder is an important tool in the process of tire curing, mainly used for curing and shaping of bias tire.

1. basic concepts
Vulcanization bladder is a hollow thin-walled rubber product of tire vulcanizer. Its material is usually butyl rubber, which is widely used because of its excellent heat resistance, aging resistance and air tightness. The B- type curing bladder for bias tire is a curing tool specially designed for bias tire, which is equivalent to the inner mold of the tire mold and plays a role of supporting and transferring heat during the curing process.

2. function and role
Supporting function: The B- type curing bladder of the bias tire expands after being inflated inside the tire, supporting the tire blank and forming internal pressure to ensure that the tire maintains the correct shape and size during the curing process.
Heat transfer medium: compressed air, nitrogen or superheated water in the capsule is used as a heat transfer medium to promote the vulcanization reaction of the tire material by heating and pressurizing, so that the tire material can achieve the expected physical and chemical properties.
Improve vulcanization quality: The use of bias tire type B vulcanization bladder can significantly improve the vulcanization quality and consistency of the tire, and enhance the wear resistance, impact resistance and service life of the tire.
