工业炸药的爆轰性能研究

Study on Detonation Performance of Industrial Explosives

用有机玻璃法测定了岩石膨化、煤矿膨化、铵梯以及乳化炸药的爆速和爆压,同时用VLWR爆轰程序对岩石膨化硝铵和铵梯炸药的爆轰参数及C-J产物的平衡组成进行了计算。结果表明,工业炸药具有低爆速和低爆压的非理想爆轰特征,而理论计算值和实验值比较接近,获得了较好的结果。

The detonation velocity and detonation pressure of rock expanded AN, colliery expanded AN, No.2 rock and emulsion explosives have been measured by polymethyl methacrylate method in this paper, and the detonation parameters and the equilibrium composition of detonation products at CJ state of rock expanded AN and No.2 rock explosives have been computed by means of the VLWR code. It is showed that industry explosives have nonideal detonation character of low detonation velocity and low detonation pressure, and the theoretic values are approximating to experimental results.
