Title
(DE) VERFAHREN ZUR HERSTELLUNG VON MITTELDICHTEN FASERPLATTEN UND FASERFORMTEILEN MIT VERRINGERTER EMISSION UND NIEDRIGER DICKENQUELLUNG
(EN) METHOD FOR PRODUCING REDUCED-EMISSION, LOW-THICKNESS SWELL MEDIUM DENSITY FIBER BOARDS AND MOLDED FIBER PARTS
(FR) PROCEDE POUR FABRIQUER DES PANNEAUX DE FIBRES A MOYENNE DENSITE ET ELEMENTS DE MOULAGE FIBREUX A EMISSIONS POLLUANTES REDUITES ET FAIBLE GONFLEMENT
Abstract
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung von Faserplatten, insbesondere mittedichten Faserplatten, aus Lignocellulosen, bei dem die Lignocellulosen chemo-thermohydrolytisch aufgeschlossen und anschließend in einem Refiner zerfasert, mit einem Bindemittel versehen, zu Fasermatten gestreut und zu Faserplatten gepresst werden, wobei die Zerfaserung der Lignocellulosen im Refiner in Anwesenheit kondensierter Tannine erfolgt.
(EN) The invention relates to a method for producing fiber boards, especially medium density fibers boards, from lignocelluloses, whereby the lignocelluloses are cooked by chemical thermohydrolysis and are then reduced to fibers in a refiner, a binder is added, the material is spread to give fiber mats and is compressed to give fiber boards. The method is characterized in that the lignocellulose are reduced to fibers in the presence of condensed tannins.
(FR) L'invention concerne un procédé pour fabriquer des panneaux de fibres, notamment à moyenne densité, en lignocelluloses. Selon l'invention, les lignocelluloses sont ouvertes par thermohydrolyse chimique, puis désintégrées dans un raffineur, dotées d'un liant, épandues en nattes de fibres et pressées en panneaux de fibres, les lignocelluloses étant désintégrées dans le raffineur en présence de tanins concentrés.
