Description

[0002] Tire vulcanization is one of the most important production processes at the end of the tire manufacturing industry, and also one of the most energy-consuming production processes. Specifically, it refers to the vulcanization of the outer tire by using a mold pressurization method. The outer diameter of the molded outer tire blank is smaller than the inner diameter of the mold. During vulcanization, a water tire or a capsule is placed in the tire blank, and high-pressure hot water is injected into the water tire. The expansion pressure of the water tire or the capsule is used to make the outer tire blank fill the mold. The outer tire vulcanization adopts a gradual heating and low-temperature long-term vulcanization method to allow the rubber to fully flow and transfer heat to ensure the vulcanization quality.
