Description

[0002] The existing large engineering tire and agricultural tire's capsule internal heating mostly adopts high pressure superheated water heating, and the superheated water heating has the following shortcomings:

[0003] The factory power system needs to consume a large amount of steam to produce high pressure superheated water, and a large amount of steam source can only rely on the heat power plant to provide; at the same time, the temperature of superheated water is limited, and it is not easy to improve the temperature of superheated water, so the vulcanization cycle of tire cannot be shortened, and the vulcanization efficiency of tire cannot be improved;

[0004] Low production efficiency and complicated process: superheated water vulcanization needs hot water pressurization and circulating water steps, slow vacuum extraction speed, frequent capsule replacement, time-consuming, and low production efficiency;

[0005] The superheated water heat content and heat factor are small, the energy loss is large, the heat conduction efficiency is low, the vulcanization temperature is not easy to control uniformly, and the tire vulcanization quality is affected;

[0006] Short capsule life, high oxygen content in superheated water, which can cause capsule surface oxidation and brittleness, leading to early damage, frequent replacement and increased cost;

[0007] Safety hazard, high pressure danger: superheated water is in a high pressure state, which has certain danger, and improper operation can easily cause safety accidents.

[0008] Tire quality defects, temperature fluctuation: superheated water temperature fluctuation will affect the uniformity and balance of tire, which may cause quality defects due to improper tire blank position.

[0009] Environmental pollution, water quality problem: the cost of soft water is high, and the loss is large, if hard water is used, it is easy to scale, difficult to clean, and affect the environment.
