Abstract
A wood board of sufficient strength which demonstrates high dimensional stability and little warping can be obtained, while the production process therefor is simplified and may be carried out in less time and at a lower cost as compared to conventional methods by means of a method for producing a wood board comprising the steps of shaving lumber to produce wooden strands; applying a binder to the wooden strands; subjecting the binder coated wooden strands to a forming process to form a preformed material 1; and carrying out a steam injection pressing in which the preformed material 1 is subjected to thermal compression molding while being moisturized so as to obtain a molded material having a water content of 5 to 15%; as well as by means of a method for producing a wood board, comprising the steps of shaving lumber to produce wooden strands; applying a binder to the wooden strands after adjusting the water content of the wooden strands to 10 to 25%, or, alternatively, adding water when applying the binder to the wooden strands so that the water content is in the range of 10 to 25%; and subjecting the binder coated wooden strands to a forming process to form a preformed material 1…
