Abstract

Il a été observé qu'il était possible d'utiliser des épaississants dans des émulsions prévues pour des compositions explosives. Ces épaississants assurent des changements rapides et réversibles de la viscosité des émulsions. L'utilisation d'épaississants permet d'obtenir des émulsions explosives présentant les caractéristiques requises de (1) réduction significative de la viscosité au cours du pompage et (2) rétablissement d'une viscosité relativement élevée une fois le pompage terminé sans endommager les composants de l'émulsion. Il semblerait que l'utilisation d'épaississants permette d'obtenir un réseau de liaisons physiques dans l'émulsion, qui peut être rompu de manière réversible.
