摘要

采用热重分析仪对电视机外壳塑料的热稳定性和降解动力学进行了研究，并在台式热解反应器上进行了溴分离实验。研究结果表明，电视外壳塑料的失重曲线分为两个不同的阶段，溴化阻燃剂的热降解主要发生在290℃~ 350℃，HIPS树脂主要发生在350℃~ 455℃。通过等温处理(约300℃)和真空处理(

Controlled Pyrolysis of Waste TV Housing Plastic Added Brominated Flame Retardants

The thermal stability and degradation kinetic of TV set housing plastic were investigated by the means of thermo gravimetric analyzer, the experiments of separating bromine were carried with a bench-scale pyrolysis reactor. The study results showed that the weight loss curve of TV housing plastic was divided into two different stages, the thermal degradation of brominated flame retardants mainly occurred at 290¡æ~ 350¡æ, the HIPS resin mainly occurred at 350¡æ~ 455¡æ. The most of bromine can be first released from the TV housing plastic by a process of isothermal treatment(about 300¡æ) and vacuum (
