    摘要： Disclosed is a method and apparatus for pyrolytically decomposing waste plastic which may contain halogen-containing polymer such as PVC. The plastic is heated at 270° to 350° C., whereby a plasticizer contained in the plastic material is decomposed and vaporized, and a chlorine-containing polymer is dechlorinated to produce hydrogen chloride. The vaporized decomposition matter and the hydrogen chloride are removed from the plastic, and the vaporized decomposition matter is separated from the hydrogen chloride. Then isolated plastic is further heated to 450° C. or higher to produce a pyrolysis product. Alternatively, the former heating step is divided into two steps of: heating at a temperature lower than 270° C., whereby a plasticizer is decomposed; and heating to 270° to 350° C., whereby a chlorine-containing polymer contained in the plastic material is dechlorinated. Accordingly, the decomposition matter of plasticizer and hydrogen chloride are separately removed from the plastic.

    摘要翻译： 公开了一种用于热分解废塑料的方法和装置，其可以含有含卤聚合物如PVC。 将塑料加热至270℃至350℃，由此使包含在塑料材料中的增塑剂分解和蒸发，并将含氯聚合物脱氯以产生氯化氢。 将汽化的分解物质和氯化氢从塑料中除去，汽化的分解物质与氯化氢分离。 然后将隔离的塑料进一步加热至450℃或更高以产生热解产物。 或者，将前一加热步骤分为两个步骤：在低于270℃的温度下加热，从而分解增塑剂; 并加热至270〜350℃，由此将包含在塑料材料中的含氯聚合物脱氯。 因此，增塑剂和氯化氢的分解物质与塑料分开除去。

    摘要： During the process of manufacturing tires, vulcanized tires are classified by the utilization of radiations into the white tire having a white rubber compound layer, or a white ribbon, and the black tire having no such white ribbon, while those tires are classified according to the external dimensions such as an inside diameter. More specifically, a radiation source provided on the side of one wallside of a tire emits radiations to the tire at a predetermined angle of inclination, while a radiation detector provided on the side of the other wallside of the tire detects the intensity of radiations which have passed through the tire, whereby the classification of tires is carried out according to the comparison of two outputs which the radiation detector produces at two predetermined relative positions of the tire and the radiation source.
