摘要： The amount of particulate matter that is forced into the passenger compartment of an automobile by the deployment of an air bag as it protects the lives of occupants is reduced by improving the filterability of the combustion products of a composition for generating gas to inflate the bag. The filterability is improved by adding a nucleating agent for alkali metal halide vapors formed during said combustion. Silica, alumina, and graphite are representative of the nucleating agents.
摘要翻译：通过提高用于产生气体的组合物的燃烧产物的过滤性来使袋膨胀，从而减少了在保护乘客的生命时通过展开气囊而被迫进入汽车的乘客室的颗粒物质的量。通过加入在所述燃烧过程中形成的碱金属卤化物蒸气的成核剂来改善过滤性。二氧化硅，氧化铝和石墨是成核剂的代表。

摘要： Gas generant pyrotechnic compositions especially suitable for inflating vehicle occupant restraint systems with nitrogen gas are described. The compositions are comprised (in wt. %) of about 65-74% of an azide, preferably sodium azide; about 17-29.5% of iron oxide, preferably ferric oxide; and about 1.0-6% metal nitrite or nitrate co-oxidizer, preferably sodium nitrate; to which base composition is added about 0.5-8% silica, alumina, titania or mixtures thereof; up to 6% bentonite and up to 4% molybdenum disulfide. Preferred driver and passenger side formulations are disclosed. The compositions burn from about 0.8 to 1.5 inches per second, have excellent slag and clinker properties, as well as excellent aging and mechanical strength characteristics when formed into cylindrical pellets or wafers. The formulation ingredients are amenable to water slurry mixing, spray drying and machine pressing into cylindrical pellets or wafers for insertion into a suitable gas generating device.
摘要翻译：描述了特别适合用于充气具有氮气的车辆乘员约束系统的气体发生器烟火组合物。组合物包含（重量％）约65-74％的叠氮化物，优选叠氮化钠; 约17-29.5％的氧化铁，优选氧化铁; 和约1.0-6％的金属亚硝酸盐或硝酸盐共氧化剂，优选硝酸钠; 向其中加入约0.5-8％二氧化硅，氧化铝，二氧化钛或其混合物的基础组合物; 高达6％的膨润土和高达4％的二硫化钼。公开了优选的驾驶员和乘客侧配方。组合物每秒钟燃烧约0.8至1.5英寸，具有优异的炉渣和熟料性能，以及当形成圆柱形丸粒或晶片时具有优异的老化和机械强度特性。制剂成分适于将水浆料混合，喷雾干燥和机械压制成圆柱形丸粒或晶片以插入合适的气体发生装置中。

The compositions are comprised (in wt. %) of about 65-74% of an azide, preferably sodium azide; about 17-25% of iron oxide, preferably ferric oxide; and about 3.5-6% metal nitrite or nitrate co-oxidizer, preferably sodium nitrate; to which base composition is added about 2.5-8% silica, alumina, titania or mixtures thereof, up to 6% bentonite and up to 4% molybdenum disulfide. Preferred driver and passenger side formulations are disclosed.The compositions burn from about 1.0 to 1.5 inches per second, have excellent slag and clinker properties, as well as excellent aging and mechanical strength characteristics when formed into cylindrical pellets or wafers.The formulation ingredients are amenable to water slurry mixing, spray drying and machine pressing into cylindrical pellets or wafers for insertion into a suitable gas generating device.
