| Abstract: | The thermal stability and degradation kinetics of TV housing plastic and brominated flame retardants were studied by means
of thermogravimetry. The effects of the treatment temperature on the removal rate of Br were investigated using a tube furnace
reactor under isothermal and vacuum conditions. The results showed that the weight loss of TV housing plastic was divided
into two stages: the thermal degradation of brominated flame retardants mainly occurred at 290°–350°C, and the degradation
of the high-impact polystyrene resin mainly occurred at 350°–455°C. Nearly 90% of Br can be removed from TV housing plastic
when the treatment temperature exceeds 280°C. |
