纳米HMX的制备及热性能分析和感度研究
Preparation,Thermal Performance Analysis and Sensitivities Study of Nano HMX
摘要
Abstract
Nano HMX was prepared by the ball milling method .The particle size distribution was analyzed by a laser particle size analyzer .At the same time ,the particle size and the morphology of nano HMX were character-ized through SEM .The thermal decomposition features and thermal stability of nano HMX were examined by a TG/DSC .Furthermore ,the explosion temperature in five seconds and the sensitivities of nano HMX were also tested .It was found that most of the particles were below 100 nm .The maximum weight loss temperature ,the apparent acti-vation energy Ea ,the self-ignition temperature and the explosion temperature in five seconds were lower than those of raw HMX by 3 4.6℃ ,11 1.9 kJ/mol ,2 1.1K and 4 9.℃ respectively .The electrostatic sensitivity and the sensitivity to flame of nano HMX were the same as raw HMX .The friction ,impact and shock sensitivities of nano HMX were decreased by 28% ,20 2.% and 56 4.% ,respec-tively .关键词
