Abstract
A process for the production of OSB wood-based panels including: a) producing wood strands from suitable wood logs; b) treating at least part of the wood strands with steam at a temperature between 80° C. and 120° C. and a pressure between 0.5 bar and 2 bar; c) drying the steam-treated wood strands; d) gluing the steam-treated and dried wood strands and, optionally, gluing the non-steam treated wood strands with at least one binder; e) scattering the glued wood strands onto a conveyor belt; and f) pressing the glued wood strands into an OSB wood-based board. The steam treatment takes place after the wood strands have been produced and made available, or after the wood strands have been sifted and separated according to the use of the wood strands for the middle and top layers of the panel. Also, an OSB wood-based panel made using the process.
