Title (EN) BOARDS PRODUCED WITH THE USE OF GRASS PLANT LIGNIN AND PROCESS FOR PRODUCING THE SAME
(FR) PLANCHES FABRIQUEES AU MOYEN DE LIGNINE DE PLANTES HERBEUSES ET LEUR PROCEDE DE FABRICATION
Abstract:
(EN) Boards produced by heating lignocellulosic material under elevated pressure for molding the same without resort to any adhesive. The boards contain 0.2 to 30 % by weight, based on the dry weight of the lignocellulosic material, of rice plant lignin so as to achieve excellent mechanical strengths and water resistance without evolution of harmful substances such as formaldehyde. To efficiently advance the thermosetting reaction of the lignin, the molding under elevated pressure is effected at 180 to 250 °C in the process for producing the boards.
(FR) Planches fabriquées par réchauffement de matériau lignocellulosique sous pression élevée afin de les mouler sans utiliser d'adhésif. Ces planches contiennent 0,2 à 30 % en poids, sur la base du poids sec du matériau lignocellulosique, de lignine de riz, ce qui leur confère une résistance mécanique et hydraulique excellente sans évolution de substances nocives, telles que formaldéhyde. Afin de favoriser la réaction thermodurcissante de la lignine, on effectue le moulage sous pression élevée à 180-250 °C pendant le procédé de fabrication de ces planches.
