| 摘 要： | 研究了含铝粉与不含铝粉的乳化粉状炸药DDT敏感性.发现没有足够、持续的外界热源,PEE不能自持燃烧,很难发生DDT现象.铝粉含量低(<4％)的PEE样品,燃烧比PEE强烈,但DDT敏感性很低.铝粉含量较高(>8％)的PEE样品,燃烧明显加快,DDT敏感性显著提高,约束条件、装填密度、药径及铝粉含量等因素都影响到乳化粉状炸药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. |
