摘要
自燃温度是工业生产中衡量可燃物质燃烧危险性的重要参数,也是量化风险评估的必要参数。针对工业常用有机可燃液体组成的不同二元混合体系的自燃温度开展实验研究,利用AITTA 551自燃温度测试仪,得到了28组168个二元可燃混合液体在不同组成和配比下的自燃温度实验数据;通过对实验数据进行分析总结,揭示了不同组分和配比二元混合液体自燃温度变化的3种不同规律,即直线型、折线型和三段型;对所得规律进行解释,分析了产生不同变化规律的原因。
Auto-ignition temperature of the combustible material is an important parameter in the process of industrial production which characterizes the risk of the material, which is also the necessary of quantitative risk assessmerit. In this paper AITTA 551 auto-ignition point tester was used to test the auto-ignition points of different binary systems, which was made of organic combustible liquids used in industry widely. Then, 28 group tests were carried out, and experimental dates of 168 binary systems with different components and volume r;tios were gained. The different components and volume ratios of auto-ignition temperature was explored. Three AIT change rules of combustible binary liquid mixtures were carried out by summarizing and analyzing such as linear rule, broken line rule and three-section rule. The rules were interpreted and the causes of the different variation were analyzed.
