Title (EN) METHOD FOR MANUFACTURING HIGH-DENSITY WOODY LAMINATE MATERIAL
(FR) PROCÉDÉ DE FABRICATION D'UN MATÉRIAU STRATIFIÉ À BASE DE BOIS DE HAUTE DENSITÉ
(JA) 高密度木質積層材の製造方法
Abstract:
(EN) The present invention enables production of a high-density strand board without using special equipment, by molding under a pressure approximately the same as that applied to produce a normal-density strand board. A pretreatment step P2 including a first treatment step P2a and a second treatment step P2b subsequent to the first treatment step P2a, is performed on a strand 5 that has not been press-molded. In the first treatment step P2a, at least one among beating treatment, high-frequency treatment, high-temperature/high-pressure treatment, high-water-pressure treatment, repeated degasifying/dehydrating treatment, and chemical treatment is performed. In the second treatment step P2b, roll-pressing treatment or flat-plate pressing treatment is performed. A strand board B of 750-950 kg/m3 is molded under a pressure of at most 4 N/mm2.
(FR) La présente invention permet la production d'un panneau de copeaux à densité élevée sans l'utilisation d'un équipement spécial, par moulage sous une pression approximativement égale à celle appliquée pour produire un panneau de copeaux à densité normale. Une étape de prétraitement P2 comprenant une première étape de traitement P2a et une deuxième étape de traitement P2b suite à la première étape de traitement P2a, est effectuée sur des copeaux 5 qui n'ont pas été moulés à la presse. Au cours de la première étape de traitement P2a, au moins un traitement parmi un traitement de battage, un traitement à haute fréquence, un traitement à haute température/haute pression, un traitement à haute pression d'eau, un traitement de dégazéification/déshydratation répété et un traitement chimique est réalisé. Au cours de la deuxième étape de traitement P2b, un traitement de pressage à rouleaux ou un traitement de pressage à plaque plate est réalisé. Un panneau de copeaux B de 750-950 kg/m3 est moulé sous une pression de 4 N/mm2 au plus.
(JA) 高密度のストランドボードを、一般的な密度のストランドボードと同程度のプレス圧力で成形できるようにして、特殊な設備を用いることなく生産できるようにする。プレス成形前のストランド5に対し、第1処理工程P2aとその後の第2処理工程P2bとからなる前処理工程P2を行う。第1処理工程P2aでは、ビーティング処理、高周波処理、高温高圧処理、高水圧処理、脱気・脱水繰り返し処理、化学処理のうちの少なくとも1つを行い、第2処理工程P2bでは、ロールプレス処理又は平板プレス処理を行う。4N/mm以下のプレス圧力で750~950kg/mのストランドボードBを成形する。
