为获得乳胶基质的热失控温度,采用改进的通风管试验研究了乳胶基质发生热爆炸的过程,试验结果表明,样品含水量越高,乳胶基质发生热爆炸的时间越久;当乳胶基质温度达到150℃时,样品开始产生明显的分解放热反应;当温度达到270℃时,乳胶基质发生剧烈的燃烧爆炸反应。可见,为了提高乳胶基质在运输和储存的安全性,应控制其温度低于150℃。
To obtain the thermal runaway temperature of emulsion matrix, the modified vented pipe test was used to study the thermal explosion process of emulsion matrix. Test results show that with water content increased, emulsion matrix can stand a longer time heat. Emulsion matrix appears obvious exothermic reaction process when the temperature is up to 150℃. And when the temperature is high to 270℃, emulsion matrix will occur severe burning explosion reaction. To improve the safety of the transportation and storage, the temperature of emulsion matrix should be controlled under 150℃.

为了研究乳胶基质在运输过程中在火灾条件下持续受热的热失控发展过程,采用TG和ARC研究了乳胶基质的热分解特性,同时采用联合国橘黄书中改进的通风管试验分析研究了乳胶基质在持续受热条件下发生热爆炸的过程。TG和ARC的试验结果表明:水分含量高的乳胶基质在受热条件下,更容易发生破乳,但反应的放热量较低。在通风管试验中,样品温度在100～146℃时,随着加热时间的变化,样品温度缓慢上升;当乳胶基质温度达到146℃后,样品温升速率明显加快,表明样品开始产生明显的放热效应;当温度达到270℃时,乳胶基质发生剧烈的热失控反应。可见,为了提高乳胶基质在运输和储存的安全性,应严格控制其运输温度。
To study the thermal runaway of emulsion matrix under continuous heating in a fire, TG and ARC were employed to detect its thermal decomposition characteristics, and modified vented pipe test(MVPT) recommended by UN for the transport of dangerous goods did to measure the temperature evolution of sample. The TG and ARC test results show that the higher water content of emulsion matrix, the easier its demulsification, and the lower heat released by reaction is. In the MVPT test, sample temperature rises slowly between 100-146℃, and above 146℃raise of temperature speeds up quickly, indicating appearance of obvious exothermic reaction process. When the temperature is up to 270℃, emulsion matrix takes place thermal runaway reaction (explosion). So the control of emulsion matrix temperature is very important for its transportation and storage safety.
