    • Gas generating compositions and methods for their use are provided. Metal complexes are used as gas generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, and sufficient oxidizing anion to balance the charge of the complex. The complexes are formulated such that when the complex combusts, nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite ammine, metal nitrate ammine, and metal perchlorate ammine complexes, as well as hydrazine complexes. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas generating compositions and to permit efficient combustion of the binder. Such gas generating compositions are adaptable for use in gas generating devices, such as automobile air bags.
    • 提供了气体生成组合物及其使用方法。 金属络合物用作气体发生组合物。 这些络合物由金属阳离子模板,含有氢和氮的中性配体以及足够的氧化阴离子组成,以平衡络合物的电荷。 络合物配制成使得当复合物燃烧时,产生氮气和水蒸气。 这种络合物的具体实例包括亚硝酸金属亚胺,金属硝酸铵和金属高氯酸铵氨络合物,以及肼络合物。 可以将粘合剂和辅助氧化剂与金属配合物组合以改善气体发生组合物的压碎强度并允许粘合剂的有效燃烧。 这种气体发生组合物适用于气体发生装置,例如汽车气囊。

    • A melt-cast explosive which shares comparable explosive properties to those of COMP B explosives and is melt-pourable and castable under conditions comparable to those of COMP B explosives, but experiences less impact, shock, and thermal sensitivity and avoids the issues of toxicity associated with COMP B. A fundamental and well-accepted component of COMP B, i.e., trinitrotoluene (TNT), is replaced with one or more mononitro-substituted or dinitro-substituted melt-cast binders, such as dinitroanisole, which can be melt-cast without presenting the toxicity drawbacks experienced with the use of TNT. The melt-cast binder can also be combined with a processing aid selected from the group consisting of alkylnitroanilines and arylnitroanilines. Preferably, the composition also includes coarse oxidizer particles and an energetic filler in fine particulate form.
    • 与COMP B爆炸物具有相当的爆炸特性的熔铸炸药,在与COMP B爆炸物相当的条件下可熔融浇注和浇注,但具有较小的冲击,冲击和热敏感性,并避免了毒性相关的问题 使用COMP B。COMP B的一个基本和被广泛接受的组分即三硝基甲苯(TNT)被一个或多个单硝基取代或二硝基取代的熔融流延粘合剂替代,例如二硝基苯甲醚,其可以熔融浇铸 而没有呈现使用TNT所经历的毒性缺点。 熔融粘合剂也可以与选自烷基硝基苯胺和芳基硝基苯胺的加工助剂组合。 优选地,组合物还包括粗氧化剂颗粒和精细颗粒形式的能量填料。
