摘要:
研究了塑料导爆管爆速成长情况，以及管内断药、极限药量、温度对导爆管的影响。采取电测法测试导爆管爆轰波成长情况；空管连接法测试断药对爆轰波的传播影响；测试了极限药量和温度对导爆管的影响。结果表明，塑料导爆管被激发后，传播800 mm后，基本可以达到稳定爆轰状态。塑料导爆管内的断药在200 mm以下不影响正常传爆。为了确保塑料导爆管不被击穿，并能正常传爆，管内的上限药量18 mg/m，下限药量12 mg/m。环境温度偏高时，温度越高，塑料导爆管管壁越软，吸收的能量就会越多，爆速越低；温度越高，导爆管越容易被击穿。
Abstract:
The detonation velocity growth of nonel and the effects of detonation parameters such as explosive internal faults, limit dose, temperature were studied. The detonation wave and the effects of explosive faults were tested by electrical measuring method and emptytube connecting method respectively. Limit explosive dose and temperature were also considered. Results show that steady detonation process happens after propagating 800 mm, and explosive faults length less than 200 mm will have no significant effect on detonation propagation. To prevent nonel tube from being penetrated and keep detonation propagating reliably, the maximum explosive loading should be set in the range of 18 mg/m and 12 mg/m. The higher the temperature, the softer the tube wall and the more energy it absorbs, and hence the lower the detonation velocity and the more likely the nonel is penetrated.
