摘要
利用HCT-3综合热分析仪对四种不同的电路板处理样品进行热重行为研究,分析了不同的废旧电路板在相同条件下的失重率,失重速率最大时的温度,热解区间等等。结果表明1#电路板的热解率远大于2#,3#和4#电路板。四种电路板的失重最大时的温度大约都在330℃左右。
In the work the pyrolysis of four different kinds of waste printed circuit boards (PCBs) were investigated through TG technology. The results showed that the pyrolysis conversion rate of 1# PCB was higher than that of 2#, 3# and 4# PCB. The maximum mass loss rate was occurred at about 330 ℃ for all of PCBs.
