primary explosive उदाहरण वाक्य
उदाहरण वाक्य
- As a general rule, PETN is considered to be either a relatively insensitive primary explosive, or one of the most sensitive secondary explosives.
- If detonators with primary explosives are used, the shock wave of the initiating blast may set off the detonator and the attached charge.
- ANFO is a tertiary explosive, meaning that it cannot be set off by the small quantity of primary explosive in a typical blasting cap.
- Conventional blasting caps use electricity to heat a bridge wire rather than vaporize it, and that heating then causes the primary explosive to detonate.
- Besides the primary explosive material in the shoes, they also contained a small amount of a highly dangerous material that can be used as a detonator.
- A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the detonation.
- PETN was used for these detonators because it was safer than primary explosives like lead azide : while it was sensitive, it would not detonate below a threshold amount of energy.
- Fulminic acid and its salts ( fulminates ), for instance mercury fulminate, are very dangerous, and are often used as detonators for other explosive materials, and are examples of primary explosives.
- Firstly, there is a major safety issue, i . e . detonators are ( like all primary explosives ) much more sensitive to shock, heat, and friction than an explosive booster.
- In spark detonators, PETN is used to avoid the need for primary explosives; the energy needed for a successful direct initiation of PETN by an electric spark ranges between 10 60 mJ.
