METHOD FOR THE PREPARATION OF OSB WOOD-BASE PANELS WITH REDUCED EMISSION OF VOLATILE ORGANIC COMPOUNDS (VOCS)

摘要

The present invention relates to a process for the treatment of wood strands suitable for the production of OSB boards, the wood strands being treated with water vapor after drying without drying, the water vapor having a temperature between 80 ° C. and 120 ° C. and a pressure between 0 , 5 bar and 2 bar over the wooden strands. The present invention also relates to a method for producing OSB wood-based panels, in particular OSB wood-based panels with reduced emissions of volatile organic compounds (VOCs), comprising the steps of a) producing wooden strands from suitable woods; b) treating at least part of the wooden beaches with steam; c) drying the steamed wooden beach; d) gluing the steam-treated and dried wooden strands and gluing non-steam-treated wooden strands with at least one binder; e) sprinkling the glued wooden beach on a conveyor be and f) pressing the glued wood strand into an OSB wood-based panel.
