摘　　要：本文采用热重-红外联用观察了由PE,PVC,PS等组成的混合塑料和单独的塑料组分的热动力学特性和热重逸出产物的分布特性。结果显示,在混合燃烧和热解时多环芳烃的排放特性和其各组份单独燃烧时的排放特性明显不同,这主要是由于混合燃烧和热解时各塑料组分因相互作用而引起热动力学性质发生了变化所致。The thermokinetics characteristics of the plastic mixture and single plastic component are analyzed in the TGA. And the distributing characteristics of the products from the TGA are investigated based on TGA-FTIR method. The results show that PAH emission characteristic of the plastic mixture is obviously different with that of any single plastic component. The reason should be due to the thermokinetics characteristic variation when the plastic components are mixed in the combustion and pyrolysis process.
