Abstract

L'invention concerne un procédé de stabilisation continue de nitrocellulose imprégnée d'eau, après traitement d'ébullition sous pression. Le gâteau de nitrocellulose formé par lavage par centrifugation après ébullition sous pression est lavé intensément à l'eau tiède pendant sa centrifugation à très grande vitesse et, après la centrifugation, il est repris dans l'eau et la suspension est déchargée. La nitrocellulose traitée par le procédé de l'invention peut être utilisée comme fulmicoton appliqué sous forme de laque.
