摘要
利用DTA、DSC以及C80微量量热仪和TAM air绝热微量热仪,对典型自燃火灾物证样品(浸油脂棉纱和50万单位的棕榈酸酯维A粉)在环境温度条件下放热性能分别进行实验测试与分析,对化学性物质热自燃危险性的评价方法进行初步探索。研究结果表明:采用高灵敏度C80微量量热仪和TAM air绝热微量热仪,对热不稳定性物质低温常温的恒温热解特性进行测试,对热不稳定性物质的稳定性和自燃火灾危险性进行评价,可以更为准确地确定热不稳定性物质发生自燃火灾的条件以及安全储运的温度条件。
The exothermic performance of typical spontaneous combustion material evidence （oil cotton and 500 thousands of Palmitate Vitamin A powder） was tested and analyzed by DTA,DSC,C80 micro-calorimeter and TAM air adiabatic calorimeter.The evaluation method of fire risk of spontaneous combustion was researched.The results showed that test the temperature pyrolysis features of thermally unstable substance,and test the spontaneous combustion fire risk and thermal stability of thermally unstable substance,by high sensitivity C80 micro-calorimeter and TAM air adiabatic calorimeter,can determine the condition for thermally unstable substance to self-ignite or storage and transport safely.
