Abstract

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.
