Abstract

L'invention concerne une amorce électrique comprenant un dispositif d'allumage et une enveloppe chargée ayant le dispositif d'allumage à sa partie d'ouverture, le dispositif d'allumage comprenant une coupe ayant un fond et remplie d'une composition d'allumage, la coupe pouvant être rompue par la flamme d'allumage; une partie en saillie pour supporter la coupe; et une bougie. Selon l'invention on utilise un copolymère d'éthylène-acétate de vinyle ou un ionomère éthylénique pour la coupe 7; on serre la partie d'adaptation de la coupe 7 sur la partie en saillie 3 et également la partie d'ouverture de l'enveloppe 9 corresponsant à la bougie 1, respectivement sur au moins une partie d'adaptation et au moins une partie de la partie d'ouverture. L'invention s'applique notamment à l'allumage d'un mélange nitrate d'ammonium-fuel oil.
