26-diamino-35-dinitropyridine-1-oxide octogen crystal coating sensitivities structures properties
TJ55; TQ564
In order to investigate the mechanical sensitivity influence of 2,6-diamino-3,5-dinitropyridine-1-oxide(ANPyO)on the octogen(HMX),the ANPyO/HMX complexes are prepared by the crystal coating method and the mixing method respectively.The structures and properties of the two kinds of samples are characterized by the scanning electron microscope,the laser particle size analysis,the thermograimetry,the differential scanning calorimetry,and the mechanical sensitivity and detonation velocity tests.Results show that the crystal coating can make better ANPyO coating on the HMX than the mixing method.For the crystal coating samples,particles are more uniform and the average sizes are all between that of ANPyO and HMX,the thermal decomposition peak temperatures are lower than that of HMX and 50.3 ℃ higher than that of the mixing method samples,and the mechanical sensitivity are lower than that of HMX and decreases more significantly.
