FIELD: process engineering.
SUBSTANCE: proposed method comprises gluing wooden shavings or fibers together. Note here that prior to gluing, wood is subjected to treatment by bisulphate in atmosphere saturated with steam, or in air saturated with steam for 3 to 8 minutes at 6 to 12 bar. In using formaldehyde-resin binders, articles with extremely lows evaporation of chemicals can be produced that feature relatively light colour.
EFFECT: reduced degree of evaporation.
