Title
(EN) A METHOD FOR OBTAINING THERMOREACTIVE BINDERS FOR A PRODUCTION OF WOOD COMPOSITE MATERIALS FROM BIRCH OUTER BARK
(FR) PROCÉDÉ POUR L'OBTENTION DE LIANTS THERMORÉACTIFS POUR LA PRODUCTION DE MATÉRIAUX COMPOSITES À BASE DE BOIS À PARTIR D'ÉCORCE EXTERNE DE BOULEAU
Abstract
(EN) The invention refers to a method for obtaining thermoreactive binders by isolating them from birch outer bark for use in the production of wood composite materials. The invention describes a process of obtaining a suberinic acid containing binders, which can be used for the production of particle boards and plywood, as well as a production method of the aforementioned particle boards and plywood by using the binders defined in the invention. The invention offers a zero waste method of birch outer bark processing, where the by-products of binder obtaining process may be used as mineral fertiliser, fuel or fuel filler.
(FR) L'invention concerne un procédé pour l'obtention de liants thermoréactifs par isolement de ceux-ci à partir d'écorce externe de bouleau, destinés à être utilisés dans la production de matériaux composites à base de bois. L’invention concerne plus précisément un procédé d'obtention de liants contenant de l'acide subérinique, qui peuvent être utilisés pour la production de panneaux de particules et de contreplaqué, ainsi qu'un procédé de production des panneaux de particules et du contreplaqué susmentionnés à l'aide des liants selon l'invention. L'invention fournit un procédé de traitement d'écorce externe de bouleau zéro déchet, les sous-produits du procédé d'obtention de liants pouvant être utilisés en tant qu'engrais minéral, combustible ou charge de combustible.
