Abstract

Zur Aufbereitung eines Gemisches aus Zellulose und granuliertem, in Wasser stark quellfähigem Polymer auf Polyacrylatbasis, wird die Mischung vor einer Weiterbehandlung oder Weiterverwertung mit einem Gemisch aus einem organischen, wassermischbaren Lösungsmittel und Wasser benetzt. Das organische Lösungsmittel führt bei einem bestimmten Mischungsverhältnis mit Wasser zu einem schlagartigen Abfall des Quellungsgrades und erleichtert dadurch die Siebtrennung zwischen Polymermaterial und Zellulose. Ein bevorzugtes Anwendungsgebiet ist die Behandlung von Superabsorber-Zellulose-Gemischen in bei der Windelherstellung entstehenden Resten.
