METHOD FOR MANUFACTURE OF WOODY FIBER BOARD

摘要

PROBLEM TO BE SOLVED: To obtain a woody fiber board having a strength equal to or higher than that of the woody fiber board by a conventional manufacturing method by using a pulverized material of a used woody fiber board to be conventionally disposed of as waste; to decrease a consumption of virgin raw material, i.e., natural wood and to consequently contribute to protection of natural environment. SOLUTION: The woody fiber board (for example, MDF, PB) is obtained by integrally heat-pressing and molding a raw material obtained by pulverizing or cutting a new wood piece and an existent woody fiber board (for example, MDF) by an adhesive. The generated raw material should preferably be a fibrous or chip-like material of 50 kg/m3-250 kg/m3in apparent specific gravity and 0.01 mm-20 mm in fiber length. COPYRIGHT: (C)2004,JPO
