| 摘 要： | 利用热重-红外光谱联用（TG-FTIR）、气相色谱（GC）、气相色谱-质谱（GC-MS）联用等分析测试手段对一种有机防火封堵材料热解后产生的烟气进行分析。热重-红外联用（TG-FTIR）分析表明在有氧和限氧条件下，热解产生的烟气都以二氧化碳为主要组分，原因可能是因为CO2主要来源于部分无机成分的分解和有机成分的脱羧反应，所以CO2的产生受氧气含量的影响较小。利用气相色谱和气相-质谱联用（GC-MS）技术，在对700℃有氧条件下产生的烟气进行全面的成分和含量分析后，测定出了21种气体组分，并对其中可能对火灾救援工作和周围环境产生不利影响的气体进行了安全性评价，用以表明这种有机防火堵料的使用在火灾中可能会暴露的一些潜在危害，为以后有机防火封堵材料的研发和改良提供一定的参考。 |

| Abstract: | Analytical testing methods such as thermogravimetric-infrared spectroscopy (TG-FTIR), gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) were used to analyze the flue gas generated after pyrolysis of an organic fireproof plugging material. TG-FTIR analysis intimated that carbon dioxide was the major component of the flue gas produced by pyrolysis, no matter under aerobic or restricted oxygen conditions. The reason might be that the carbon dioxide mainly came from the thermal decomposition of some inorganic components and decarboxylation of some organic components, which were less affected by oxygen. The composition and content of the flue gas pyrolyzed under aerobic atmosphere at 700℃ were comprehensively analyzed by GC and GC-MS, and 21 gas components were determined. The safety assessment of the gases may adversely affect the fire rescue work and the surrounding environment was carried out to reveal the potential hazards that may be exposed by using this organic fireproof plugging material in a fire. The present work provides a certain reference for the future development and improvement of organic fireproof plugging materials. |
