Title Study on Particle Size of Synthetic Sensitivity of RDX
Abstract Effect of particle size of RDX on impact sensitivity,friction sensitivity and shock sensitivity is system artically studied.The particle size tested is pided into 4 grades.The impact sensitivity and friction sensitivity are characterized with 50% drop height and the probability of explosion.The results show that impact , friction and shock sensitivities of RDX decrease with the reduction of particle size of RDX. The mechanism and factors of particle size affecting mechanical sensitivity are theoretically analyzed. The results are significant in the research and application of explosives.
Keywords:RDX;particle size;impact sensitivity;friction sensitivity;shock sensitivity
