通过合理假设,从谢苗诺夫(Semenov)热爆炸理论和8个非等温动力学方程,导出了估算含能材料(EMs)热爆炸临界温度(Tb)的2个通式和它们的6个派生式。从EMs的非等温DSC曲线可获得DSC曲线偏离基线的起始温度(T0)、onset温度(Tei)和放热分解反应的动力学参数。由方程T0ior ei=T00 or e0+a1βi+a2βi2+…+aL-2βiL-2,i=1,2,…,L可得到T00和Te0值,随后用6个派生式可计算Tb值。对1,4,5,8-四硝基-1,4,5,8-四氮杂双呋咱[3,4-c:3′,4′-h]十氢化萘,1,4,5,8-四氮杂双呋咱[3,4-c:3′,4′-h]十氢化萘,1,3,4-三硝基咪唑烷酮[4,5-b]呋咱[3,4-e]哌嗪,咪唑烷酮[4,5-b]呋咱[3,4-e]哌嗪,1,3,4,8-四硝基咪唑烷酮[4,5-b]呋咱[3,4-e]哌嗪,1,4,5,8-四硝基-1,4,5,8-四氮杂萘呋咱[3,4-b]十氢化萘,1,3,5-三硝基-1,3,5-三氮杂呋咱[3,4-f]环庚烷,由6个派生式所得的Tb值甚接近。
Through reasonable assumptions, from the Semenov thermal explosion theory and the eight non-isothermal kinetic equations, two general formulas for estimating the thermal explosion critical temperature (Tb) of energetic materials (EMs) and their six Derived. The onset temperature (T0), onset temperature (Tei) and kinetic parameters of the exothermic decomposition reaction of the DSC curve from the baseline were obtained from the non-isothermal DSC curves of EMs. The values of T00 and Te0 are obtained from the equations T0ior ei = T00 or e0 + a1βi + a2βi2 + ... + aL-2βiL-2, i = 1,2, ..., L, and then the Tb values can be calculated using six derivatives.
