MANUFACTURING METHOD OF CARBONIZED BOARD MADE DESIGN DURING CARBONIZATION

摘要

PURPOSE: A manufacturing method of a carbonized board is provided to form drawings, letters, patterns, logos etc during a carbonization. CONSTITUTION: A manufacturing method of a carbonized board comprises the steps of: placing a lignum board manufactured in a flat plate shape with a timber raw material mixed with an adhesive on a lower part pressurizing plate in a carbonization tub (S11); positioning a mold in which design of embossment is portrayed on the upper side of the lignum board (S12); positioning an upper part pressurizing plate to apply an even pressure on the upper side of the mold (S13); and manufacturing a carbonized board formed with the design by heating the carbonization furnace after making a non-oxidizing atmosphere by blocking the carbonization furnace from the outside (S14).
