Abstract: A tire direct-pressure shaping and electromagnetic induction heating curing method and apparatus uses an inner metal mold including large and small segments, a telescoping mechanism, supporting plates attached to the segments, and induction heating coils. A cavity in the middle of the segments is filled of phase change material. The temperature of the mold rises rapidly by the thermal effect of an eddy current generated on the surface of the segments to heat the green tire. When the middle part of the segment is heated to a certain temperature, the phase change material absorbs and stores the excess heat. Therefore, the temperature of the middle part of the segment differs from one of two ends of the segment. Once the tire is cured, the inner mold in the expanded condition and the outer mold support very high pressure for the green tire together.

Abstract translation: 轮胎直压成形和电磁感应加热固化方法和装置使用包括大小段的内金属模具，伸缩机构，附接到段的支撑板和感应加热线圈。 分段中间的空腔填充有相变材料。 模具的温度由于在节段表面产生的涡流的热效应而迅速升高，以加热生轮胎。 当段的中间部分被加热到一定温度时，相变材料吸收并储存多余的热量。 因此，段的中间部分的温度不同于段的两端之一。 一旦轮胎固化，处于膨胀状态的内模和外模一起支撑生轮胎的非常高的压力。

Abstract: The present invention relates to a loop-route production method and system for polyvinyl chloride, and belongs to the intersecting fields of coal chemicals, polymer materials and chemical machinery. Limestone and carbon materials such as coal are reacted in an oxygen-enriched high temperature furnace to obtain calcium carbide and carbon monoxide, and then acetylene and carbon monoxide are respectively produced from calcium carbide and dichloroethane (obtaining ethylene, etc., through methanol or ethanol); both of the end products are combined to form a closed-loop; acetylene and dichloroethane are reacted to produce a vinyl chloride monomer, which is polymerized to obtain polyvinyl chloride. The system of the present invention mainly includes a device for pulverizing and mixing solid raw materials, a device for conveying solid materials, an oxygen-enriched calcium carbide furnace, an oxygen-enriched air-blowing device, a tube-shell thermostatic reactor, a fixed bed tubular reactor, a fluidized bed reactor, an acetylene generator having a heat exchanger, a fixed bed reactor and a polymerization reactor. The present invention has the advantages of not only removing the dependence on oil resources during the production of polyvinyl chlorides, but also totally eliminating the mercury pollution.
