Title:
SOLID MOLDED ARTICLE AND MANUFACTURING METHOD OF SOLID MOLDED ARTICLE, AND DIAPHRAGM AND MANUFACTURING METHOD OF DIAPHRAGM
Document Type and Number:
Japanese Patent JP2022151571
Kind Code:
A
Abstract:
To provide a solid molded article that can be manufactured with a simple and short tact by using a naturally-derived material without requiring large scale facilities, and to provide a diaphragm and manufacturing methods of them.SOLUTION: A solid molded article is molded by mixing wood meal whose maximum grain size is 1000 μm or less, cellulose nanofiber and water and then heat-pressing. A manufacturing method of the solid molded article includes: a mixing step (S1) for mixing the wood meal whose maximum grain size is 500 μm or less, 0.1-50 wt.% of the cellulose nanofiber with respect to 100 wt.% of the wood meal in terms of solid content, and water; a forming step (S2) for forming the material mixed in the mixing step (S1) into a metal mold; a heating press step (S3) for heat-pressing by the metal mold; and a taking-out step (S4) for taking out the molded article from the metal mold.SELECTED DRAWING: Figure 1
