Invenstigation On The Thermal Activiation And Interaction Of New Energy Materials

In this paper,the thermal decomposition and physic and chemical interaction between style new energy materials were analysised by using new thermalysis technology of high pressure differential scanning calorimeter?PDSC?and others of Temperature-jump FTIR?T-jump/FTIR?spectroscopy and isomal TG-DTG.The fast thermolysis of 3,4-dinitrofurazanfuroxan?DNTF?test discovered that there are dozens of gasous produced and the relative mol percentage concentrations of the main gaseous products?CO,CO₂,NO and NO₂?released from the thermolysis of DNTF are affected by pressures and temperatures and the relative mol percentage concentrations ratios of NO/NO₂ and CO/CO₂ are changed as the pressures change.These results reveal that the two competitive reactions and the heterogeneous gas/condensed phase and homogeneous gas phase reactions may occur in the secondary and tertiary class of reaction for fast thermolysis of DNTF.The thermal actions of 3,4-diphenlfuroxan?DPF?and its ramification series were studied.the thermal analysing characteristics and thermal decomposition kineticspreferences had been obtained.The decomposition of 3,4–diphenlfuroxan was believed to be initiated by O-N and C-C bond homolysis,its made the thermal behavior of 3,4-diphenlfuroxan?DPF?ramification had been affected visibly,the thermal stability changing orderliness.The decomposition of RDX at various sizes have been tested and the decomposition kinetics have been calculated according to the Kissinger's method,There is no obviously distinction about decomposition kinetics of liquid phase decomposition of micro and nano RDX.The catalytic thermal decompositions of RDX system by B,Mg and Al powders were studied by PDSC and TG,It was found that the phase state in the decomposition of the material has a great influence on the catalytic decomposition,the catalytic efficiency of the"liquid-solid"and"gas-solid"catalytic modes is much higher than that of"solid-solid".there is heat dissipation or dilution effect.By the Isothermal thermogravimetric technology,the interaction and thermal decomposition between NC/NG and ADN system have been studied,the intial reaction process and mechanism function were analysised.The physics interaction of volatilizable material 1,3,3-trinitroazetidine?TNAZ?with1,3,5-trin-itro-1,3,5-triazacyclohexane?RDX?have been studied,we found there were eutectic between solid-liquid change process,the change law could be obtained by producted phase diagram using PDSC,there are good consistency of T-X and H-X method,and in comparison with T-X method,H-X method has a faster and simple excellence.
