Abstract

Procédé de décomposition hydrolytique de mousses de polyuréthanne à cellules ouvertes. Il consiste à chauffer rapidement la mousse en la mettant en contact avec de la vapeur d'eau saturée dans une chambre à vide chauffée. On réalise ainsi la séparation d'un polyol et d'une diamine liquides de haute qualité. L'invention concerne également un appareil conçu pour réaliser cette décomposition hydrolytique et cette séparation.
