Booster - denbakuyaku (English spelling)

Japanese: 伝爆薬 - でんばくやく(英語表記)booster
Booster - denbakuyaku (English spelling)
An explosive used to ensure the explosion of explosives or blasting agents, also called a booster. Explosives used to detonate explosives, such as explosives, ammonium nitrate oil explosives, and certain types of water-containing explosives, are difficult to detonate reliably using only a detonator or primary explosive. For this reason, a booster explosive is placed between the primary explosive or detonator and the explosive that is insensitive to shock to ensure the explosion. Tetryl or pentrite-based explosives are used as boosters for explosives, and dynamite or cap-sensitive water-containing explosives that can be detonated with a single detonator are used as boosters for ammonium nitrate oil explosives.

Japanese:
炸薬や爆破薬を確実に爆ごう(轟)させるために用いる爆薬で,ブースターともいう。爆弾,砲弾,地雷などに装てん(塡)して炸裂させるための爆薬,つまり炸薬や,硝安油剤爆薬,ある種の含水爆薬のような爆破薬は雷管や起爆薬だけで確実に爆発させることは難しい。このために,起爆薬や雷管と衝撃に対して鈍感な爆薬との間に伝爆薬を介在させて,爆ごうの確実性を期する。炸薬の伝爆薬としてはテトリルやペントリットを基材とした爆薬が使われ,硝安油剤爆薬の伝爆薬としてはダイナマイトや雷管1本で起爆できるキャップセンシティブ(雷管起爆性)含水爆薬などが使われる。
