Abstract:
1. A method for manufacturing a wood section material, comprising: processing a wood sample having a density lower than or equal to 700 kg/m drying the wood panels to reduce their moisture content to between 6% and 20%; polishing the dried wood panels to form a panel blank material; pressing opposing surfaces of the panel blank material using two hot pressing panels having a temperature between 140° C. and 200° C., wherein said pressing using two hot pressing panels comprises placing the panel blank material on a hot press having a closing speed of between 0.5 mm/sec and 6 mm/sec, controlling the panel blank material compression ratio at between 10% and 30% and pressure at between 20 MPa and 50 MPa, controlling the hot press temperature at between 150° C. and 160° C. and maintaining the temperature and pressure for between 30 minutes and 120 minutes; pre-carbonizing the panel blank material, wherein said pre-carbonizing the panel blank material comprises raising the hot pressing panels temperature to between 170° C. and 180° C. and maintaining the temperature and pressure for between 30 minutes and 120 minutes and maintaining the temperature and pressure for between 30 minutes and 120 minutes; carbonizing the panel blank material, wherein carbonizing the panel blank material comprises raising the hot pressing panels' temperature to between 200° C. and 225° C. and maintaining the temperature and pressure for between 45 minutes and 120 minutes after pre-carbonization; cooling the panel blank material; and controlling moisture content of the panel blank material.
