摘要： A gas generator includes, a housing provided with a gas discharge port, an ignition chamber, accommodating an igniter and a transfer charge, provided on an end portion of the housing, a combustion chamber disposed within the housing and accommodating a gas generating agent, a rupturable closing member partitioning the combustion chamber from the ignition chamber and including a rupturable portion ruptured upon an actuation of the gas generator, and an inner tube extending from the closing member toward the gas discharge port inside the combustion chamber. The inner tube defines outside thereof a space containing the gas generating agent, and defines inside a hollow space. The inner tube is provided with a plurality of through holes. The inner tube includes one end communicating the hollow space with the ignition chamber to transfer the transfer charge in a burning state toward an opposite end when the rupturable portion is ruptured.

摘要： The present invention is directed to a process for preparing light curable energetic polymeric binders. The process for preparing such binder comprises the steps of mixing a pre-polymer such as PGN or GAP having a terminal hydroxyl group with a solvent and adding reactants wherein the reactant has a light curable moiety and a pre-polymer reactive moiety. Catalysts such as carbodiimide and DMAP may be further added to the mixture.

摘要： Provided is a method for preparing copper azide and cuprous azide encapsulated by conductive metal-organic framework. The method uses a conductive copper-containing metal-organic framework material as a precursor, and completes the azidation of the precursor by means of a liquid-solid electrochemical azidation reaction. Copper azide and cuprous azide nanocrystals are highly uniformly embedded within a conductive framework, which may effectively avoid the agglomeration of copper azide and cuprous azide, and reduce static charge generated by friction, displacement, and the like. Meanwhile, the conductive framework may promote the effective transfer of charge, avoid the accumulation of static charge, and improve the electrostatic safety. In addition, the liquid-solid electrochemical azidation reaction has advantages such as being safe and efficient, having a short reaction time and having strong operability, and the preparation process is compatible with a MEMS process, which is beneficial for the application of copper azide and cuprous azide materials in micro devices.

摘要： The present invention relates to processes for making macromolecular networks, macromolecular networks made by such processes, and methods of using such macromolecular networks. Such process employs a low amount of amine compound as a reaction accelerant. The rates of chemical reaction are thereby easily controlled over several orders of magnitude, permitting efficient catalysis and control of reaction conditions needed to produce thermochemically stable macromolecular networks.
