燃料空气炸药中铝粉与液相的反应特性（英文）

The Reactivity between Aluminum Powder and Liquid Phase of Fuel-air Explosives

为了研究燃料空气炸药中固相组分(铝粉)与液相组分(IPN和烃类燃料MC10)的反应特性,用高压DSC测试铝粉与IPN及MC10在氮气气氛中的分解过程。结果表明,在IPN分解之前存在MC10的氧化过程。与纯MC10液体相比,MC10在IPN存在条件下氧化过程更明显,氧化温度更低,同时铝粉能够改变MC10的高温分解过程。Al/IPN/MC10三组分共存体系在高温条件下具有更稳定的状态,有利于提高燃料空气炸药的性能。

In. order to study the reactivity of solid phase component （aluminum powder ）and liquid phase components isopropyl nitrate （IPN） and hydrocarbon, fuel MC10 in. fuel-air explosive, the decomposition, process of aluminum powder with IPN and MC10 under nitrogen, atmosphere conditions was measured by high pressure DSC . The results show that there is an. oxidation, process of MC10 before the decomposition, of IPN. Compared with the pure liquid MC10, the oxidation, process of MC10 with IPN is more obvious and the oxidation, temperature is much lower than, that of the pure MC10. The aluminum powder can. verify the high temperature pyrolysis process of MC10. The coexistence system of Al/IPN/MC10 has more stable status under high temperature conditions, which is favorable to improve the performance of FAE.
