摘　　要：21世纪初,ResoDyn声共振混合器公司首次开发出了声共振混合(RAM)技术。这项技术利用声波在一种材料中形成多个微混合区,而不是传统的叶轮或转子搅拌或行星混合器产生的大混合区。这种技术可用于制药、化妆品和散装粉末混合的大规模生产,与传统的高剪切含能材料加工方法(如行星混合)相比,RAM具有潜在的优势,其优点包括更短的混合时间、改善混合均匀性、减少废物输出、没有运动部件(点火源)以及混合高粘度、难混合成分的可能性(与行星混合器相比)。RAM已成为研发和生产推进剂、炸药、烟火剂的首选加工技术。从RAM原理角度出发,介绍了RAM技术在共晶炸药、纳米铝热剂制备中及其在固体推进剂和高聚物粘结炸药(PBX)加工中的应用。ResoDyn Acoustic Mixers Incorporation developed a mixing technique known as Resonant Acoustic®Mixing(RAM)in the early 21st century.This technology uses acoustic waves to create multiple micro⁃mixing zones within a material rather than the bulk mixing generated by traditional impeller or rotor agitation or planetary mixer.RAM technology can be used for the large⁃scale production of pharmaceuticals,cosmetics,and bulk powder mixing.For energetic materials,RAM is considered to have potential advantages over traditional high⁃shear processing methods(e.g.planetary mixing),including shorter time scales,improved mix homogeneity,reduced waste output,absence of moving parts(an ignition source),and the potential to mix high⁃er viscosity,‘unmixable’compositions(compared to planetary mixers).RAM has become the processing technology of choice in the development and production of propellants,explosives,and pyrotechnics.A summary of applications of RAM in the field of energetic materials,including the formation of co⁃crystal explosives and nano thermites and the processing of propellants and PBXs,is detailly overviewed in this text.
