RECOVERY OF PRECIOUS METAL AND RARE METAL FROM LIQUEFATION RESIDUES OF AUTOMOBILE SHREDDER RESIDUES

汽车碎纸机残渣（ASR）是汽车报废处理后产生的工业废弃物。聚氨酯泡沫、聚丙烯和ABS树脂主要是轻ASR塑料。在本研究中，使用便携式反应器（容器容积：120 ml）进行了这些塑料的液化实验。将49.75 g有机溶剂（机油）和0.25 g塑料样品混合在容器中，搅拌器转速为600转/分。然后，所有的聚氨酯泡沫和聚丙烯在250度的温度下熔化10分钟，尽管大多数ABS树脂在300度的温度下不熔化10分钟。

Automobile Shredder Residue (ASR) is the industrial waste generated after the processing of end-of-vehicles. Urethane foam, polypropylene and ABS resin are plastics mainly in light ASR. In this study the experiments on the liquefaction of these plastics were carried out using potable reactor (vessel volume : 120 ml). 49.75 g of organic solvent (engine oil) and 0.25 g of plastics samples were mixed in the vessel at the agitator rotation of 600 rpm. Then all of urethane foam and polypropylene were melted at the temperature of 250 degrees for 10 minutes although most of ABS resin was not melted at the temperature of 300 degrees for 10 minutes.
