摘要:
为了研究保险粉储运过程中的热稳定性,利用C600微型量热仪考察温升速率、水份、酸雨对保险粉热分解特性的影响,分析分解活化能和绝热条件下达到最大反应速率时间Tmrad等动力学参数。结果表明:随着温升速率的增加,保险粉热分解起始放热温度逐渐增大;水份和酸雨均对保险粉的分解具有促进作用,其反应起始放热温度比保险粉分别降低了95.5℃和101.2℃,放热量分别增大了31J/g和446J/g,失控分解危险性大大增加。有模拟结果得知,保险粉分解活化能E值在150-210kJ/mol之间;Tmrad且在常温常压条件下,干燥保险粉几乎不会发生自燃危险
Abstract:
The thermal decomposition reaction characteristic of the sodium hydrosulfite was studied in order to investigate the thermal stability of the storage or transportation. The effect of heating rate,water, acid rain on the thermal decomposition reaction of the sodium hydrosulfite were measured by the C600 micro-calorimeter.The decomposition activation energy and Tmrad were also analyzed. The research showed that the temperature rise rate caused a significant increase of initial exothermic temperature of the thermal decomposition. The decomposition of sodium hydrosulfite was promoted by both of water and acid rain, the initial exothermic temperature of the reaction was decreased by 95.5℃ and 101.2℃ and heat release increases 31J/g and 446J/g,the risk increased bigger. The simulated result showed the decomposition activation energy E of sodium hydrosulfite was between 150-210kJ/mol and the sodium hydrosulfite almost has not spontaneous combustion risk at room temperature and atmospheric pressure.
