Analysis of Products from Thermal Decomposition of Waste Computer Mainboard

  • Received Date: 08 Sep 2008

  • 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 bromized organic compounds.These products mainly come from the decomposition of the organic polymer and tetrabromobisphenol A in waste computer mainboards.
