Video Description

Вогнепровідний шнур (safety fuse, blasting fuse, bickford fuse, zündschnur f, бікфордів шнур) — шнур з серцевиною з димного пороху, оточений зовнішнім та внутрішнім обплетенням, вологоізолюючою мастикою; швидкість горіння вогнепровідного шнура становить приблизно 1 см/с. Застосовується як засіб збудження детонації капсуля-детонатора при вогневому підриванні. Для підпалення зарядів здавна застосовувався гніт — бавовняний чи лляний джгут, просочений селітрою чи міцним лугом, що уможливлює йому горіти без полум'я повільно і стало зі швидкістю 1 см за 1-3 хвилини. Простішим варіантом є звичайна порохова доріжка. Перший зразок безпечного вогнепровідного шнура винайшов 1831 року англійський винахідник Вільямом Бікфорд. Первісно складався з порохової трубки, покритої водонепроникним і лакованим джутовим тросом. Звідси походить і неточна назва будь-якого вогнепровідного шнура — «бікфордів шнур». Сучасний вогнепровідний шнур складається з напрямної нитки, скрученої з трьох бавовняних сталок, кожна з яких має різне просочення. Це забезпечує досить точне дотримання швидкості горіння шнура. Піротехнічна суміш, якою заповнюється шнур, не потребує атмосферного кисню, тому шнур горить без відкритого полум'я, і здатний горіти навіть у воді. У срср випускали три марки вогнепровідних шнурів: ОША (ВША) — Вогнепровідний шнур з асфальтованою оплеткою ОШДА (ВШДА) — Вогнепровідний шнур з двічі асфальтованою оплеткою ОШП (ВШП) — Вогнепровідний шнур з пластиковим покриттям .
