该文从理论上分析废发射药具备炸药的三要素，从理论和实验两方面论述了用废发射药制备粉状炸药时，必须降低废药的粒度，从而达到提高炸药爆轰感度和传爆能力。在实验研究的基础上，提出了直接利用废药粉、废药粉与药粒级配、废药粉与氧化剂级配作粉状炸药的３条途径。文章的结论认为利用废发射药制备粉状炸药是一个资源化利用废药资源的方向。 This paper theoretically analyzes the three elements of explosive propellant possessing explosives, discusses the theoretical and experimental aspects of the use of waste propellant preparation of powdered explosives, we must reduce the particle size of waste, so as to enhance the detonation sensitivity explosives and explosion ability. On the basis of experimental research, three ways of directly using the waste powder, waste powder and particle size distribution, waste powder and oxidant grade as powder explosives are proposed. The conclusion of the article holds that the use of waste propellants to prepare powdered explosives is a resource-oriented use of waste resources.
