An ignition charge for an initiator provided with an igniting mechanism for setting aflame an ignition charge by the heat generated by an exothermic element connected via a pair of current conducting pins in response to an electric signal is a slurry ignition charge which is formed mainly of a mixture consisting of zirconium as a fuel component and potassium perchlorate as an oxidizing agent component. The ignition charge for the initiator contains nitrocellulose as a binder component in an extrapolated compounding ratio of 0.1 % by weight or more and 0.5 % by weight or less based on the total amount of zirconium and potassium perchlorate and isoamyl acetate as a solvent in an extrapolated compounding ratio of 12.5 % by weight or more and 14.0 % by weight or less based on the total amount of zirconium and potassium perchlorate. The ignition charge is spread on the exothermic element and dried. The ignition charge is for the initiator of a gas generator, particularly an electric gas generator.
一种用于起爆器的点火装药,带有一个点火装置,通过一对导电针连接的放热元件产生的热量响应电信号点燃点火装药。作为粘合剂成分的硝化纤维素(根据锆和高氯酸钾的总量,推算的复合比例为 0.1%(重量)或以上,0.5%(重量)或以下),以及作为溶剂的乙酸异戊酯(根据锆和高氯酸钾的总量,推算的复合比例为 12.5%(重量)或以上,14.0%(重量)或以下)。将引燃剂涂在放热元件上并烘干。点火药剂用于气体发生器,特别是电动气体发生器的引发器。
