Title (EN) METHOD FOR THE MANUFACTURE OF ADHESIVE PRODUCTS AND AN ADHESIVE PRODUCT MANUFACTURED ACCORDING TO THE METHOD
(FR) PROCEDE DE FABRICATION DE PRODUITS ADHESIFS ET PRODUIT ADHESIF FABRIQUE SELON CE PROCEDE
Abstract:
(EN) A method for the manufacture of an adhesive product suitable for use in the manufacture of wood particle board and other wood products which adhesive product includes a large proportion of the spent liquor from the sulfite pulping of lignocellulose and is readily applicable to the manufacture of particle boards using conventional apparatus and methods, and leads to the production of glued wood products of commercially acceptable properties, which meet the commercial standards for such products. According to the invention the manufactured adhesive product consists of 50-90 parts by weight of urea formaldehyde resin solids and from 10-50 parts by weight of the spent liquor dry solids basis. The adhesive product also contains as a key component from 0.2 to 4.0% by weight of ammonium ion (expressed as NH3) on a sulfite spent liquor solids basis.
(FR) Procede de fabrication d"un produit adhesif utilisable pour la fabrication de planches en particules de bois et autres produits en bois. Le produit adhesif fabrique comprend une grande proportion de liqueur provenant du traitement au sulfite de la pulpe de lignocellulose et s"applique directement a la fabrication de planches en particules de bois utilisant les machines et les methodes conventionnelles; il permet la production de produits en bois encolles commercialement acceptables et repondant aux criteres de qualite en vue de leur commercialisation. Le produit adhesif fabrique selon l"invention consiste en 50-90 parties en poids de resine solide de formaldehyde uree et de 10-50 parties en poids de solides secs de liqueur. Le produit adhesif contient aussi, comme composant cle de 0,2 a 4% en poids d"ions ammonium (NH3) calcule sur la base de la quantite de solides de la liqueur.
