    • A gas generator composition, primarily containing perchlorate and cellulose acetate is provided to generate a large amount of gas without forming any substantial amount of harmful carbon monoxide. A metal oxide is additionally incorporated in an amount of more than 5% by weight and not more than 40% by weight. For example, 50 to 87% by weight of potassium perchlorate and 8 to 26% by weight of cellulose acetate are incorporated in the composition. The gas generator composition contains 36% by weight or less of bitetrazole metal hydrate, preferably bitetrazole manganese dihydrate, since it forms no corrosive residue after burning. The composition contains a nonmetallic compound consisting at least of nitrogen and hydrogen and containing at least 11% by weight of nitrogen. As such compound, nitroguanidine, guanidine nitrate, etc. is employed. The compounds preferably contains 10 to 83% by weight of nitrogen. The compound is preferably incorporated in an amount of 10 to 45% by weight. The gas generator composition is molded into a desired form, such as pellet, rod and disc and loaded in the combustion chamber of a gas generator. The composition is ignited by firing an igniter and burned to generate a gas.
    • 提供主要含有高氯酸盐和乙酸纤维素的气体发生剂组合物以产生大量的气体而不形成任何大量的有害一氧化碳。 另外以超过5重量%且不超过40重量%的量掺入金属氧化物。 例如,在组合物中加入50〜87重量%的高氯酸钾和8〜26重量%的醋酸纤维素。 气体发生剂组合物含有36重量%或更少的四唑金属水合物,优选的是四唑锰二水合物,因为它在燃烧后不形成腐蚀性残渣。 该组合物含有至少由氮和氢组成的含有至少11重量%氮的非金属化合物。 作为这样的化合物,可以使用硝基胍,硝酸胍等。 化合物优选含有10至83重量%的氮。 该化合物的掺入量优选为10〜45重量%。 气体发生剂组合物被模塑成所需的形式,例如颗粒,棒和盘,并装载在气体发生器的燃烧室中。 通过点燃点火器点燃组合物并燃烧以产生气体。
