Title (EN) METHOD OF MANUFACTURING OSB WITH ACOUSTIC DAMPENING PROPERTIES
(FR) PROCÉDÉ DE FABRICATION DE PANNEAUX OSB À PROPRIÉTÉS D'AMORTISSEMENT ACOUSTIQUE
Abstract:
(EN) A manufacturing process for manufacturing wood products with acoustic dampening properties. A noise-dampening polymer is introduced in-line in the manufacturing process to achieve higher acoustic performance. The polymer can be a viscoelastic polymer which is added during blending of the lignocellulosic strands prior to mat formation, or sprayed or otherwise coated on the lignocellulosic strands during mat formation, prior to formation of any boards or panels.
(FR) Cette invention concerne un procédé de fabrication pour fabriquer des produits à base de bois ayant des propriétés d'amortissement acoustique. Un polymère insonorisant est introduit en ligne dans le processus de fabrication pour obtenir des performances acoustiques supérieures. Le polymère peut être un polymère viscoélastique qui est ajouté pendant le mélange des brins lignocellulosiques avant la formation du mat, ou pulvérisé ou autrement déposé sur les brins lignocellulosiques pendant la formation du mat, avant la formation de n'importe quel type de planche ou de panneau.
