DDT Sensitivity of Powdery Emulsion Explosives
-
摘要: 研究了含鋁粉與不含鋁粉的乳化粉狀炸藥DDT敏感性.發現沒有足夠、持續的外界熱源,PEE不能自持燃燒,很難發生DDT現象.鋁粉含量低(<4%)的PEE樣品,燃燒比PEE強烈,但DDT敏感性很低.鋁粉含量較高(>8%)的PEE樣品,燃燒明顯加快,DDT敏感性顯著提高,約束條件、裝填密度、藥徑及鋁粉含量等因素都影響到乳化粉狀炸藥DDT的敏感性.Abstract: The DDT sensitivity of powdery emulsion explosives (PEE) containing aluminum or not is investigated. It is found that PEE can not self-keep burning and DDT occurs when the content of aluminum is less than 4% without external adequate and continuous heat energy. When the content of aluminum is higher than 8%, the burning of PEE hastens obviously and the DDT sensitivity increases largely. It is concluded that the DDT sensitivity of PEE is affected by many factors such as restriction, loading density, particle size, and the content of aluminum.
