Title (EN) IMPROVED PROCESS FOR MAKING AND FILLING A PBX COMPOSITION
(FR) PROCÉDÉ AMÉLIORÉ POUR LA FABRICATION D'UNE COMPOSITION D'EXPLOSIF À LIANT PLASTIQUE (PBX) ET LE REMPLISSAGE EN COMPOSITION DE PBX
Abstract:
(EN) The invention relates to a cast explosive composition. A process for formulating a homogenous crosslinked polymer bonded explosive composition comprising the steps of : i) forming an admixture of precure castable explosive composition, comprising an explosive material, a polymerisable binder, and a cross linking reagent which comprises at least two reactive groups each of which is protected by a labile blocking group, wherein the labile blocking groups, comprise at least one resonant acoustic mixing stimulus labile linkage, ii) applying resonant acoustic mixing stimulus to the admixture, causing the at least one resonant acoustic mixing stimulus labile linkage to be removed and release said cross linking reagent, to cause the cure process to start.
(FR) L'invention concerne une composition explosive coulée. Un procédé de formulation d'une composition explosive liée à un polymère réticulé homogène comprend les étapes consistant à : i) former un mélange d'une composition explosive coulable pré-durcie, comprenant un matériau explosif, un liant polymérisable, et un réactif de réticulation qui comprend au moins deux groupes réactifs dont chacun est protégé par un groupe de blocage labile, les groupes de blocage labiles comprenant au moins une liaison labile de stimulus de mélange acoustique résonant, ii) appliquer un stimulus de mélange acoustique résonant au mélange, mettre en oeuvre le retrait de ladite liaison labile de stimulus de mélange acoustique résonant et libérer ledit réactif de réticulation, pour provoquer le lancement du processus de durcissement.
