Title (EN) GAS-GENERATING COMPOSITION
(FR) COMPOSITION GENERATRICE DE GAZ
Abstract:
(EN) The present invention relates to a solid gas-generating composition comprising: -a) a polymeric binder selected from the group consisting of polyethylene glycol and diethylene glycol polyadipate;- b) an oxidising charge consisting of a mixture of (b1) ammonium perchlorate or ammonium chlorate with (b2) an alkaline or alkaline-earth nitrate selected from the group consisting of sodium nitrate, potassium nitrate, strontium nitrate and barium nitrate. It also relates to a pyrotechnic charge comprising the composition according to the invention in a structure. Finally, it relates to the use of the composition according to the invention or the pyrotechnic charge according to the invention for generating clean gas for fast flushing of submarine ballasts.
(FR) La présente invention concerne une composition solide génératrice de gaz comprenant : -a) un liant polymère choisi dans le groupe constitué par le polyéthylène glycol et le polyadipate de diéthylène glycol; -b) une charge oxydante constituée par un mélange de (b1) perchlorate d'ammonium ou chlorate d'ammonium avec (b2) un nitrate alcalin ou alcali no-terreux choisi dans le groupe constitué par le nitrate de sodium, le nitrate de potassium, le nitrate de strontium et le nitrate de baryum. Elle concerne en outre un chargement pyrotechnique comprenant la composition selon l'invention dans une structure. Elle concerne enfin l'utilisation de la composition selon l'invention ou du chargement pyrotechnique selon l'invention pour la génération de gaz propre pour la chasse rapide aux ballasts de sous-marin.
