废电线热解过程产物分析

The thermal decomposition of waste computer wire

模拟研究了废电脑电线热解特性和热处理产物.结果表明,废电脑电线热解过程出现3个剧烈失重阶段,第1剧烈失重阶段主要是聚合物分解,第2剧烈失重阶段主要是增塑剂分解,阻燃剂分解持续整个实验过程.废电脑电线热解产物既有6～16个C原子的油状有机物,也有烃类小分子有机化合物、有机氯化物和HCl.热解产物中有多种毒害物质,必须加以控制.

The pyrolysis characteristics, thermal decomposition products from waste computer wire were simulant studied. Results show that waste computer wire has three acutely weight loss stages, of which the first is decomposing of the organic polymer, the second is decomposing of the Plasticizer, and decomposing of flame retardants persists throughout the experiment. A variety of organic compounds could probably be produced in the thermal decomposition, such as aromatic oil compounds comprised 6 ～ 16 caibon atom, little numerator organic compounds, chloridized organic compounds and HCI. The pyrolysis products have diversiform poisonous and toxic sudstances. Its pollution controlling is necessary
