TATB和NQ对DNTF结晶过程的影响
Effect of TATB and NQ on the Crystallization Process of DNTF
摘要
Abstract
To investigate the effect of TATB and NQ on DNTF crystallization,Hot Stage Microscopy was employed to observe the crystallization processes of pure DNTF and its composites with TATB and NQ.Differential scanning calorimetry(DSC)was utilized to analyze the non-isothermal crystallization kinetics.The Avrami,Jeziorny,Mo Zhisun,and Hu-Zhao-Gao-Zhao equa-tions effectively described these processes.Results demonstrate that TATB and NQ reduce DNTF supercooling,increase freez-ing point temperatures by 21℃ and 20℃,respectively.Solidification rates improved significantly,with crystallization line speeds increasing by 197％for DNTF/TATB and 203％for DNTF/NQ.Both the Avrami and Jeziorny equations accurately re-present the crystallization processes.Average Avrami indices are 3.73 for DNTF,3.09 for DNTF/TATB,and 3.27 for DNTF/NQ.Calculations using the Mo Zhisun equation show solidification rates in the order:DNTF/NQ＞DNTF/TATB＞DNTF.Acti-vation energies for crystallization are 288.50kJ/mol for DNTF,234.65kJ/mol for DNTF/TATB,and 193.71kJ/mol for DNTF/NQ.Insensitive explosives(TATB/NQ)enhance DNTF crystallization rate and density,optimize the melt-cast explosive process,and improve charge quality and safety.关键词
