FIELD: process engineering.
SUBSTANCE: invention relates to woodworking, particularly, to production of wood boards. Here, moisture content of wood chips is measured. Required moisture content varies from 5% to 25%, preferably, from 5% to 20%, more preferably, from 8% to 20%. In case measured moisture content is lower than preset magnitude, it is increased. In case measured moisture content is higher than preset magnitude, chips are subjected to pre-drying. Then, chips are dipped in water solution of fire-resistant chemical composition. Chips are separated. At least partial drying of chips is performed. Binder is applied on chips to form wood board therefrom of preset shape.
EFFECT: higher strength.
