Abstract
Le procédé consiste à recouvrir partiellement des plaques de poudre par un matériau inhibiteur de combustion. On prépare une composition visqueuse 5 de matériau inhibiteur de combustion, on positionne sur la plaque de poudre 1 un écran sérigraphique 3 comportant des ouvertures 4, on applique sur cet écran 3 la composition visqueuse 5 d'inhibiteur de combustion et on râcle cette composition sur cet écran, après quoi on retire l'écran 3 pour permettre la polymérisation de la composition 5 d'inhibiteur de combustion déposée sur la plaque de poudre 1. Application aux chargements pyrotechniques en plaques pour armes à tube de propulsion.The process consists of partially covering the powder plates with a combustion inhibiting material. A viscous composition 5 of combustion inhibitor material is prepared, a silkscreen 3 comprising openings 4 is positioned on the powder plate 1, the viscous composition 5 of combustion inhibitor is applied to this screen 3 and this composition is scraped on. this screen, after which the screen 3 is removed to allow the polymerization of the composition 5 of combustion inhibitor deposited on the powder plate 1. Application to pyrotechnic charges in plates for propulsion tube weapons.
