METHOD FOR COMPRESSING AND PERMANENTLY FIXING WOOD, AND CONSOLIDATED WOOD

摘要

PROBLEM TO BE SOLVED: To provide a method for compressing and permanently fixing a wood by which a wood is compressed and thermally treated into such a form that its compressed state is permanently fixed and is made available for actual use as a lumber without drying it. SOLUTION: A wood set in a consolidated state by compression is thermally treated and is finished as a consolidated wood by fixing its consolidated state. In this manufacturing method, the wood to be compressed for use is an air-dried one having a moisture content not more than 12%. The air-dried wood loaded into a compression mold in such a way that it is kept in contact with the inner wall face of the mold, is compressed into a compressed wood by putting the air-dried wood under pressure at a compression rate not less than 50%. Further, in order to fix the compressed state of the compressed wood, the compressed wood held in the consolidated state inside the compression mold is held airtightly and thermally treated.
