Document Type and Number:
Japanese Patent JP2021107135
Kind Code:
A
Abstract:
To provide a method for manufacturing a wooden fiber board having a white color close to that of a wood chip before defibrillated.SOLUTION: A manufacturing method of a wooden fiber board 1 comprises a defibrillating process S11 for defibrillating from heated wood chip T into a fiber F after heating the wood chip T made from coniferous trees under an atmosphere including moisture and a molding process for molding the wooden fiber board 1 by compressing and heating the defibrillated fiber F. The defibrillating process S11 comprises a step of generating a single fiber fa and a fiber assembly fb in a state before defibrillated into the single fiber fa as a fiber F from the wood chip T. In the defibrillating process S11, the wood chip f is defibrillated so that the fiber assembly fb of which opening does not pass through a sieve of 150 μm is in a range of 40 mass%-52 mass% relative to the defibrillated fiber F.SELECTED DRAWING: Figure 3
