WOOD FLOUR MOLDED ARTICLE OF EVERY SHAPE HAVING BIODEGRADABILITY, HIGH DENSITY AND HIGH STRENGTH USING AIR DRIED WOOD FLOUR AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a wood flour molded article molded into an arbitrary shape capable of using wood flour in an air-dried state as wood flour under test in molding wood flour even if the wood flour is not brought to a full-dried state and having water resistance, biodegradability, high density, high strength and high hardness, and its manufacturing method. SOLUTION: This manufacturing method for the wood flour molded article (7) has a process for preforming the wood flour (1) under test by isotropic pressurization in a cold hydrostatic pressure apparatus (CIP apparatus) (3) and a process (B) for finally molding the preformed article (4) obtained in the preforming process under ultrahigh pressure by isotropic pressurization in a hot hydrostatic pressure apparatus (WIP apparatus) (6).
