Detonator - Lycan

A container filled with explosives to ignite or detonate gunpowder or explosives. The container can be made of metal or plastic. Detonators that are attached to live or blank guns to ignite smokeless powder are called ignition detonators, and gun detonators are one type of detonator. Detonators that are attached to explosives to detonate them are called detonation detonators, and industrial detonators and electric detonators are two types of detonators. Industrial detonators use a fuse to detonate, while electric detonators detonate by igniting an ignition ball when electricity is passed through them. There are instantaneous detonators that detonate directly when electricity is passed through them, and delayed detonators that have a delay between electric ignition and detonation. Detonators with a time interval of 0.25 s are called DS, and those with an interval of 10 to 25 ms are called MS. There are also electric detonators for seismic exploration that have a time interval of 0.1 ms or less from passing electricity to detonation. With an instantaneous electric detonator, the time from when electricity is applied to when it detonates is about 2 ms. Detonators come in sizes 1 through 10, depending on the amount of high explosive packed inside, and as the size number increases the amount of explosive increases and the detonator becomes more powerful. Number 6 detonators are the most commonly used worldwide. According to the JIS standard, the tube length is 35 mm, the outer diameter is 6.5 mm, the point explosive is 0.4 g, and the base charge is 0.45 g.

火薬または爆薬を点火または点爆するために，起爆薬を容器に装填したもの．容器としては金属またはプラスチックが用いられる．実砲，空砲などに装着して無煙火薬に点火するものを点火用雷管と称し，銃用雷管がこれに属する．爆薬に装着して点爆するためのものを点爆用雷管と称し，工業雷管，電気雷管がこれに属する．工業雷管は導火線を用いて点爆し，電気雷管は通電により点火玉が発火して点爆する仕組みとなっている．電気雷管は通電してそのまま点爆させる瞬発電気雷管，電気点火と点爆との間に延時薬を入れた段発電気雷管がある．段発電気雷管の時間間隔を0.25 s おきにしたものをDS，10～25 ms 間隔にしたものをMSという．このほかに通電から点爆までの時間を0.1 ms 以下にした地震探鉱用電気雷管というものもある．瞬発電気雷管では，通電から点爆まで2 ms 程度である．雷管には内部に詰められている高性能爆薬の量によって1号から10号までがあり，号数が大きくなるにつれて薬量が増加して強力になる．世界的には6号雷管がもっとも普通に用いられる．JISでは管長35 mm，外径6.5 mm，点爆薬0.4 g，添装薬0.45 g である．
