  • 摘要: 采用热重差热联用分析仪研究了废旧酚醛树脂电路板的热解特征,结果表明,热失重曲线有两个主要快速失重阶段(270℃—350℃,350℃—480℃),通过裂解气相谱质谱联用仪分析其主要裂解产物为苯酚、溴酚、二氧化碳、对甲苯酚、邻异丙烯基苯酚、邻甲苯酚、对异丙基苯酚、糠醛等.
    Abstract: Pyrolysis characteristics of waste phenolic-resin-based printed circuit boards(PR-WPCBs)have been studyed by thermogravimetry and differential scanning calorimetry(TG-DSC).The reactions in two distinct stages of thermagravimetic process(270℃-350℃,350℃-480℃)were discussed.In addition,the compositions of pyrolysis products were analysed by pyrolysis gas chromatography mass spectrometry(Py-GC/ MS).The pyrolysis products were mainly composed of phenol,bromophenol,carbon dioxide, g-methylphenol,p-isopropylenephenol,2-methylphenol,o-isopropylphenol and furaldehyde.
