减小密度梯度提高雷管威力

Decreasing Density Gradient for Strength of Detonators

生产8~#纸亮火雷管的药柱一次压药成型的新工艺,存在着药柱密度不均匀、影响起爆威力的不足之处。本文介绍了在装药量和压药压力上略作改动,便可提高爆速2％的新方案,具有一定的参考价值。

When making detonafor No. 8 with paper shell, charge densify is non-uniform due to once-charging form, so initiation strength is decreased. In this paper a new charging method is presented. So long as explosive weight and pressing pressure are slightly charged, the detonation velocity can be two percentage higher than old method.
