Thermal hazard assessment of TKX-50 under adiabatic condition

摘要

The hazard assessment of TKX-50 was studied under adiabatic condition by using accelerating rate calorimeter (ARC). RDX, HMX and CL-20 were also studied to compared with TKX-50. The adiabatic experiment obtained the data including initial self-heat temperature, adiabatic temperature rise and temperature rise rate, etc. The data of adiabatic decomposition kinetics and the value of SADT were calculated. The results show that the adiabatic initial self-heat temperature of the four explosives are all above 180□. The maximum temperature rise rate of TKX-50 is the lowest in the four explosives, which indicate the decomposition process of TKX-50 is the mildest. Assessing the thermal safety by SADT is in the order of HMX>TKX-50 >CL-20>RDX.
