摘要:
为了研究表面包覆有氟橡胶F2311 的ANPyO造型粉(ANPyO/F2311)的热安全性，使用DSC-TG法研究了ANPyO/F2311的热分解反应过程，通过Kissinger法、Ozawa法等多种计算方法分析其热分解机理，计算得出热分解活化能、指前因子、动力学机理函数微分式、自加速分解温度、热点火温度以及热爆炸临界温度等相关参数。进而计算出在323.15 K环境温度下，特征尺寸1 m的ANPyO/F2311在不同形状（球、无限圆柱、无限平板）时的临界热爆炸温度Tacr、热感度概率密度函数S（T）、安全度DS和热爆炸概率PTE。从结果可得出,ANPyO/F2311具有良好的耐热性能，球形样品的热安全性相对较高，无限平板样品的热安全性相对最低。
Abstract:
In order to study the thermal safety of ANPyO coated with fluorine rubber F2311 (ANPyO/F2311), the thermal decomposition reaction process of ANPyO/F2311 was studied by DSC-TG method. The thermal decomposition mechanism was analyzed by Kissinger method, Ozawa method and other calculation methods. The thermal decomposition activation energy, pre exponential factor, differential equation of kinetic mechanism function, self-accelerating decomposition temperature, thermal ignition temperature, and thermal explosion critical temperature were obtained. Then the critical thermal explosion temperature Tacr, thermal sensitivity probability density function S(T), safety degree DS and thermal explosion probabilit PTE of ANPyO/F2311 samples with critical dimension of 1 m under different shapes (sphere, infinite cylinder, infinite plate) were calculated at 323.15 K. The results show that ANPyO/F2311 has good heat resistance, the thermal safety of spherical sample is relatively high, and that of infinite plate sample is relatively low.
