环保型慢速锰系延期药的制备及燃烧性能
Preparation and Combustion Properties of an Environmentally Friendly Slow-burning Manganese-based Delay Composition
摘要
Abstract
Aiming at the pollution problem associated with combustion products in traditional long-delay slow-burningcomposi-tions dominated by tungsten-based systems,a manganese-based slow-burning delay composition was selected.This formulation employs manganese powder as the fuel,with cuprous oxide(Cu2O)and potassium perchlorate(KClO4)serving as oxidizers.A minor addition of potassium perchlorate enhances ignition reliability.The composition was prepared using dry mixing followed by three-dimensional ball milling technology,and subsequently pressed into a sealed casing.Burning rate and combustion heat value were measured under varying influencing factors.The results demonstrate that Mn/Cu2O/KClO4 composition offers a wide adjustable burning rate range(3.7-8.2mm/s)while ensuring good delay precision and low temperature sensitivity.As the manganese powder content increases from 10％to 20％,the pressing pressure rises from 160MPa to 320MPa,and with binder addition,the burning rate increases accordingly.Furthermore,a higher combustion heat value correlates with a faster burning rate.X-ray diffraction(XRD)analysis of combustion residues confirms the presence of environmentally benign compo-nents,such as MnO2,CuO,and KCl.Thus,the goals of achieving long delay time,slow burning rate,high delay precision,low temperature coefficient,and environmentally friendly combustion products are fulfilled.关键词
