Abstract
The thermal decomposition behaviors of PBX based on HMX-10 #-159(10 #-159),PBX based on HMX-10 (JO-10),PBX based on HMX-9 (JO-9 )and single-compound explosive HMX under the adiabatic condition were studied by an accelerating rate calorimeter (ARC).The changing curves of adiabatic decomposition temperature and temperature conversion rate fraction with time,and temperature rise rate and pressure with temperature were obtained. The kinetic parameters of adiabatic decomposition and self-accelerating decomposition temperature (SADT)were calculated.SADT was used as the criterion of comparing the thermal stability of four kinds of explosives.Results show that the adiabatic decomposition of four kinds of explosives can be divided into four stages:induction period,acceleration period,deceleration period and decomposition of residue.Four kinds of explosives are experienced in long induction period and short acceleration period,and releasing heat rapidly and with obvious pressure effect.The initial decomposition temperature of 10 #-159,JO-10,JO-9 and HMX are 89.95,104.70, 114.41 and 153.58℃,respectively and the SADT under 25 kg packaging standard condition are 80.90,111 .71 , 119.10 and 187.86℃,respectively.The thermal stabilities of four kinds of explosives decrease in the order HMX>JO-9>JO-10 >10 #-159.关键词
