基于硝化棉助燃的含能粘合剂爆热特征值测试研究OA北大核心CSTPCD

Tests and studies were performed to characterize the energy properties of the target energetic binders,such as the combustion heat,enthalpies of formation and explosion heat characteristic values.The rationality of the energy properties as quanti-tative indexes for energy characterization of energetic binders were evaluated,and the method of using nitrocotton(NC)as combu-rent to test the explosion heat characteristic values of energetic binders was explored.The results show that when the mass ratio of energetic binder/NC reaches 1∶5,most energetic binders can be fully burned.The explosion heat characteristic value of energetic binder can be accurately measured by using nitrocellulose as the comburent.The explosion heat characteristic values of PGN and PVN measured by this method are 3164 kJ·kg-1 and 4713 kJ·kg-1,respectively,and the relative errors with the literature val-ues are less than 5%.The combustion heat can not accurately reflect the energy advantage of energetic binders.The energy charac-teristics of energetic binders can be well characterized by the explosion heat characteristic values,avoiding the self-contradictory of evaluation system caused by the difference between positive and negative enthalpy of formation.Under the condition of isolating oxy-gen,the energy contribution of energetic binders increase in the order of GETPE<FATPE<GAP<PBAMO<NC(12%)<PGN<PVN.
