| 摘 要： | 氮气气氛下,以TN型液晶为实验材料,利用TGA-FTIR联用仪研究热解失重特征及过程产物;同时利用GC-MS对管式炉实验系统热解产物进行分析。结果表明,TN型液晶热解失重起始温度为120℃,剧烈失重温度为220℃~430℃;热解产物除了含CO2外,还含有1~5个碳原子官能团的苯、苯酚、苯呋喃等组成的芳香族化合物、多环芳烃以及丙烷为主的烃类有机物。这些有机物绝大多数是有毒有害物质,可进一步通过焚烧热解产物来实现TN型废液晶无害化处理。

| Abstract: | The pyrolysis weight loss of twisted nematic liquid crystal was studied in nitrogen atmosphere by TGA FTIR. The pyrolysis products from tube furnace experimental system were analyzed GC-MS. The result indicates that the temperature of initial weight loss is 120℃ and that of apparent weight loss is 220℃~430℃. The pyrolysis products are mainly aromatic compounds besides carbon dioxide, which include benzene, phenol, benzene furan with 1~5 carbon functional groups, polycyclic aromatic hydrocarbons and hydrocarbon organic matters mainly composed of propane. Most of the organic matters are poisonous and harmful and can be harmless by further incinerating. |
