Abstract

본 발명은 공기압 타이어의 가류공정시 블래더내에 초기의 수증기와 질소깨스의 공급후 상기 블래더내부 압력을 일정하게 유지하는 보상단계(27)을 갖는 공기압 타이어의 가류 방법에 있어서, 상기 보상단계(27)를 일정시간(△t₂) 경과후 공기누출체크단계(5)로 전환하여 블래더내부 압력차이가 기준치 이상되는 시점(t₃)에서 혼합탱크에 내재된 질소깨스-수증기 혼합기체를 블래더 내부로 공급하며, 상기 블래더와 혼합탱크를 1개 이상으로 함을 특징으로 하는 공기압 타이어의 가류방법에 관한 것으로서 내부의 기체의 누출에도 불구하고 상기 블래더 내의 누출보상압력(3′)을 일정하게 유지함과 동시에 다단계의 누출보상온도(3)를 유지할 수 있어 타이어 가류에 필요한 정상압력(23′) 및 정상온도(23)와 동일 또는 근접하게 됨에 따라 가류도 부족으로 인한 불량 공기압 타이어의 생산을 방지하고, 생산 작업에 영향을 주지 않고 가류설비의 보수계획에 따라 보수유지가 가능하며, 가류기에 질소깨스의 안정적인 공급이 가능한 특징이 있다.In the vulcanization method of a pneumatic tire, the present invention has a compensation step (27) which maintains a constant pressure of the bladder after supplying initial steam and nitrogen gas into the bladder during the vulcanization process of the pneumatic tire. 27) is switched to the air leakage check step (5) after a predetermined time (△ t ₂ ) to blaze the nitrogen gas-vapor mixture gas contained in the mixing tank at the time (t ₃ ) when the bladder internal pressure difference is greater than the reference value (t ₃ ). It further supplies to the inside, and the bladder method of the pneumatic tire characterized in that at least one of the bladder and the mixing tank, the leak compensation pressure (3 ') in the bladder despite the leakage of the gas inside It is possible to maintain a constant and at the same time maintain the leak compensation temperature (3) of the multi-stage, so that the vulcanization is also insufficient as the normal pressure (23 ') and the normal temperature (23) required for tire vulcanization Avoid due to poor production of pneumatic tires, without affecting production operations are maintained according to the maintenance plan and possible cure of the plants, the possible features of a reliable supply of nitrogen kkaeseu groups vulcanization.
