Abstract

Verfahren zur Gewinnung von Cellulose mit folgenden aufeinanderfolgende Schritten:
Es handelt sich um ein Einweichen der cellulosehaltigen Rohstoffe aus Krautpflanzen in einer Alkalilösung, thermomechanisch-chemisches Verarbeiten der Rohstoffe in einem Doppelschneckenapparat, umfassend eine beheizte Kammer, 2 innerhalb der Kammer installierte, parallel gekoppelte Wellen, auf denen alternierende Förderschneckensegmente und Zerkleinerungsnockensegmente montiert sind, Waschen, Bleichen, Waschen, Ausschleudern und Trocknen. Vor dem Waschen wird eine zusätzliche thermomechanisch-chemische Verarbeitung in einem Doppelschneckenapparat, auf dessen Wellen alternierende Förder- und Bremsschneckensegmente montiert sind, durchgeführt.Process for obtaining cellulose with the following sequential steps:
It involves soaking the cellulosic raw materials from cabbage plants in an alkali solution, thermomechanical-chemical processing of the raw materials in a twin screw apparatus comprising a heated chamber, 2 parallel coupled shafts installed inside the chamber on which alternate screw segments and shredding cam segments are mounted, washing , Bleaching, washing, spin-drying and drying. Before washing, additional thermomechanical-chemical processing is carried out in a twin-screw apparatus, on the shafts of which alternating conveyor and brake screw segments are mounted.
