Beschreibung
Zusammenfassung:	The present invention relates to a priming powder composition for initiators, and to a priming powder for initiators using the same, wherein the priming powder composition for initiators comprises 52 wt% of zirconium (Zr), 42 wt% of potassium perchlorate (KClO_4), 1 wt% of graphite, and 5 wt% of a binder Viton, the average particle size of Zr is 2 m, the average particle size of KClO_4 is 6 m, and the average particle size of the graphite is 1 m. The present invention has an advantage of being able to manufacture the priming powder composition for initiators with high-reliability, which has low standard deviation properties at the maximum pressure. 본 발명은 착화기용 기폭제 조성물 및 이를 이용한 착화기용 기폭제에 관한 것으로, 지르코늄(Zr) 52 중량%, 과염소산칼륨(KClO) 42 중량%, 그라파이트 1 중량%, 바인더인 Viton 5 중량%을 포함하고, 상기 지르코늄의 평균 입자크기는 2㎛, 과염소산칼륨의 평균 입자크기는 6㎛, 그라파이트의 평균 입자크기는 1㎛이다. 본 발명은 최대압력에서 낮은 표준편차 특성을 갖는 고신뢰성의 착화기용 기폭제를 제조할 수 있는 이점이 있다.
