硝酸铵乳胶在持续受热条件下的热失控特性
Developing process of thermal runaway for ammonium nitrate emulsion under continuous heating
摘要
Abstract
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.关键词
