Abstract

La présente invention concerne un procédé de fabrication de panneau de plancher utilisant du contreplaqué, et, plus particulièrement, un procédé de fabrication de panneau mural et de panneau de plancher utilisant du contreplaqué, pouvant augmenter la surface de support inférieure du contreplaqué au cours de la compression et du moulage du contreplaqué afin de permettre la fixation d'une force de support stable, de sorte que le procédé peut améliorer la résistance du panneau par compression à une densité uniforme indépendamment des différents types de contreplaqué, et maintenir une planéité et une épaisseur uniformes du panneau. En outre, le procédé permet d'obtenir une excellente planéité et une excellente texture par rapport à la surface du panneau et de former une irrégularité en forme de grille sur la surface inférieure du panneau afin de permettre l'application régulière d'un adhésif et d'augmenter la force d'adhésion pendant la construction d'un panneau.
