Title (EN) METHOD OF SHAPING, PREFERABLY BENDING, HARDENED WOOD FIBER BOARDS
(FR) PROCEDE DE FORMAGE, DE PREFERENCE DE PLIAGE, DE PANNEAUX EN FIBRES DE BOIS DURCIS
Abstract: front page image
(EN)Method of shaping, preferably bending, hardened, flat wood fiber boards comprising cellulose fibers, lignin and hardening oil by moistening, heating, bending and subsequent cooling. Moistening is carried out with a chemical solution which temporarily dissolves the lignin, facilitates the penetration of liquid and releases the fibre bonds, whereafter the boards are heated to about 80-120°C, subsequent to which they are bent or moulded to the desired, predetermined shape.
(FR)Le procédé ci-décrit sert à former, de préférence à plier, des panneaux plats en fibres de bois durcis comprenant des fibres de cellulose, de la lignine et de l'huile durcissante par humidification, chauffage, pliage puis refroidissement. L'humidification est effectuée à l'aide d'une solution chimique qui dissout temporairement la lignine, facilite la pénétration de liquides et desserre les liaisons fibreuses, les panneaux étant ensuite chauffés à environ 80-120°C, après quoi ils sont pliés ou moulés selon la forme prédéterminée désirée.
