改进型钠谱线翻转法测量塑料导爆管输出产物的温度

Determination of the Temperature of Output Flame of Nonel Tube with Modified Sodium Line Reversal Method

用改进型钠谱线翻转法测定了塑料导爆管爆轰输出火焰的温度 ,所测导爆管为黑索今和铝粉为主装药的普通型导爆管、变色型导爆管和经济变色型导爆管。试验测得三种导爆管的爆轰输出火焰温度都在 2 5 0 0 K左右 ,且在 30 0 mm的火焰传播距离之内 。

The temperature of the output flame of detonated nonel tube were determined through modified sodium line reversal method.The main charge of the three models nonel tube(general nonel tube,color changeable nonel tube and economic color changeable nonel tube)are RDX and powdery aluminum.Experiments show that the temperature of the output flame of the three models of nonel tube are 2500K approximately.And within 300 mm of the flame transferring distance,temperatures of the flame can keep on the same level.
