- Abstract
Aluminum powder is the most commonly used metal fuel in the explosives industry, and its reaction characteristics directly affect the release of energy properties of ignition explosives. The reactivity differences between nano-aluminum powder and micron aluminum powder were compared, and the use of nano-aluminum powder in explosives and propellants was summarized. Application progress. In terms of ignition performance, combustion performance and reaction completeness, as well as its impact on the detonation performance of mixed explosives and propellant combustion performance, the reactivity of nano-aluminum powder is much higher than that of micron aluminum powder. Nano-aluminum powder is used in mixing In explosives, many properties of mixed explosives can be improved, such as detonation velocity, detonation heat, shock wave overpressure peak, etc.; applying nano-aluminum powder to propellant can significantly increase the burning rate and improve the properties of combustion products. It is pointed out that nano-aluminum powder The high reactivity makes the preparation and storage of high-purity nano-aluminum powder extremely difficult. It is recommended to increase research on the preparation and storage technology of high-purity nano-aluminum powder. The research results provide important reference for the application of nano-aluminum powder in explosives.
