Abstract
(DE)
Verfahren zur Bearbeitung von Cellulosecarbamat, wobei Cellulosecarbamat mit einem Quellmittel oder Lösungsmittel vermischt werden. Die Mischung wird durch Druckausübung und gegebenenfalls Temperaturerhöhung in eine gewünschte Form gebracht, wobei die Menge an Cellulosecarbamat die maximale Löslichkeit des Cellulosecarbamats im Quellmittel oder Lösungsmittel für die vorgegebenen physikalischen Bedingungen Temperatur, Druck und verfügbare Lösezeit um einen Faktor von 1,5 bis 6 übersteigt.
(EN)
Method for processing cellulose carbamate, in which cellulose carbamate is mixed with a swelling agent or solvent. Through exertion of pressure and optionally increase of temperature, the mixture is brought into a desired shape; the amount of cellulose carbamate exceeds the maximum solubility of the cellulose carbamate in the swelling agent or solvent by a factor of 1.5 to 6 for the prevailing physical conditions of temperature, pressure and available dissolution time.
(FR)
L'invention concerne un procédé de traitement de carbamate de cellulose, consistant à mélanger du carbamate de cellulose avec un agent gonflant ou un solvant. Une forme désirée est conférée au mélange par application de pression et éventuellement par augmentation de la température, la quantité de carbamate de cellulose étant 1,5 à 6 fois supérieure à la solubilité maximale du carbamate de cellulose dans l'agent gonflant ou le solvant pour les conditions physiques prédéfinies en termes de température, de pression et de temps de dissolution disponible.
