Abstract
Procédé général de production d'une poudre enduite d'un préventif et à combustion progressive, plus particulièrement d'une poudre de propulsion pour armes comportant des canons, dans lequel on alimente sur la poudre une substance préventive filmogène, de préférence polymérisable, à l'état non cohérent ou dispersé dans une phase liquide qui est éliminée par la suite. La formation de l'enduit préventif sur la poudre granulaire ou la poudre découpée en pièces courtes(poudre dite tubulaire) se fait dans un lit fluidisé. La substance préventive se présente sous la forme d'un polyuréthane dispersible dans l'eau contitué d'un isocyanate aliphatique et d'un polyester de caprolactone.
