| 摘 要： | 引 言作为一种重要的电子产品 ,印刷线路板广泛应用于多个领域 ,伴随着电子产品的更新换代 ,大量的印刷线路板被废弃淘汰 ,另外在印刷线路板生产过程中也会有 30 %～ 5 0 %的废料产生 ,仅我国台湾省每年需要处置的废弃印刷线路板就达 10万吨[1] .从组成可以看出 ,PCB废弃物中包含有大量直接或间接来源于石油产品的聚合物高分子材料 ,具有很高的热值 ,利用它们既可产生能源也可生产相关的化学产品[2 ] .作为一种新型的废弃物 ,印刷线路板废弃物的合理处置开始在一些发达国家受到关注[3～ 5] .目前大规模处理该类废弃物主要还是采取传统的…

| Abstract: | Pyrolysis kinetics of a kind of printed circuit board waste was investigated under various conditions with thermogravimetry (TG) in the present work. The dynamic thermogravimetric analysis curve and its derivative were analyzed to obtain information on the kinetic parameters. The data from experiments were processed to determine the pyrolysis mechanism of printed circuit board and the kinetic parameters such as activation energy E(kJ/mol) and pre-exponential factor A(1/min). A tube-type apparatus was used to pyrolyze printed circuit board waste under different conditions,and the products were analysised by using FTIR and EPMA. |
