Abstract
L'invention porte sur un panneau (1) à copeaux orientés produit au moyen d'une presse (22) à courroie continue et d'un liant d'isocyanate, par exposition à la vapeur du mat (18) de bois avant son introduction dans la presse. L'exposition à la vapeur génère de l'humidité qui assouplit les fibres ligneuses et intensifie l'écoulement de lignine dans le mat. De plus, l'humidité réagit au liant d'isocyanate en formant des polyurées à partir du liant (le liant préféré étant pMDI), ce qui réduit les conditions de durcissement (température, pression et durée) nécessaires à la presse pour faire fusionner le mat et le liant. Le liant d'isocyanate réagit également à des groupes hydroxyle dans la cellulose et les fibres d'hémicellulose du bois de manière à permettre la formation de liaisons chimiques et physiques avec le bois. Le panneau à copeaux orientés sortant de la presse a une teneur en humidité très élevée et un gonflement en épaisseur plus résistant dans des conditions humides.
