| 摘 要： | 采用热重分析仪-傅市叶变换红外光谱仪(TG-FTIR)、管式炉试验系统、气相色谱仪-质谱仪(GC-MS)等研究了电脑主板的热解特性和热处理产物.研究结果表明:废电脑主板热解过程剧烈失重阶段为300～460℃,该温度段约失重20%,加热垒600 ℃后失重非常缓慢.废电脑主板热解产物中既有含8～15个C原子的苯酚等芳香族化合物,也有1～4个C原子的小分子有机化合物,且热解过程中还产生多种含溴有机物;这些热解产物来源于废电脑主板中有机聚合物和四溴舣酚A的分解. |

| Abstract: | The pyrolysis characteristics and thermal decomposition products of waste computer mainboards were investigated by the TG-FTIR (thermogravimetric analyzer-Fourier transform infrared spectroscopy), a duct-furnace pyrolysis system and the GC-MS (gas chromatography-mass spectrometer). The results show that waste computer mainboards have an acute mass loss from 300 to 460 ℃ and about 20% of mass is lost at this stage, and the loss velocity over 600 ℃ is very slow. The thermal decomposition products of a waste computer mainboard include aromatic compounds comprised of 8 to 15 carbon atoms such as phenol, organic compounds with 1 to 4 carbon atoms and bromizedorganic compounds. These products mainly come from the decomposition of the organic polymer and tetrabromobisphenol A in waste computer mainboards. |
