PYROLYSIS CHARACTERISTICS RESEARCH OF WASTE PLASTICS OF ELECTRONIC WASTE

This paper selects the waste plastics of two typical electronic components of the computer circuit board, which are parallel communication port and slot, the influences of different heating rates and components on the pyrolysis and their kinetics analysis are researched. Pyrolysis experiments are performed under a nitrogen atmosphere, the experimental temperature ranges from room temperature to 1000 degrees C, and heating rates are 10 degrees C / min and 20 degrees C / min. The result shows that the plastics of parallel communication port and slot in the weight loss have similar variation trend, and with the changing of heating rates, the temperature that reach the maximum pyrolysis rates also change. The weight loss rate of slot is lower than the parallel communication port. The pyrolysis rates increase with the increasing of the heating rates, the remainder mass fraction of the same samples are basically the same under different heating rate.
