S172022 微少爆薬の安全で安定な起爆に関する研究([S172-02]化学装置の安全(2))

Abstract

High explosives are useful material to generate great amount of energy in short time. Since controlling their releasing energy is hard, the use of explosives is limited to specific fields and industries. The reduction of the explosive powder mass used at a time makes the handling safe, and use of explosives in a continuous producing process leads the new utility of the explosion. Based on this concept, we enclosed small mass explosives with a polyethylene sheet and initiate them by using metallic foil explosion. In present study, we use comparatively small power-supply unit(200uF,450V) with an improved foil explosion system. Finally we observed much better results of the initiation of PETN explosives.
