JOINT COMPOSITION OF OIL PALM THIN BOARD AND JOINING METHOD OF THE OIL PALM THIN BOARD

摘要

PROBLEM TO BE SOLVED: To enable joining of a plywood board by using the trunk of oil palm, without adding a component different from a component that the oil palm originally has.;SOLUTION: A joint composition of oil palm thin board W is produced as follows: while rotating an oil palm trunk WD of a predetermined length in its circumferential direction, a cutter CT is abutted on the trunk WD from an outer periphery on a rotary lathe to skin the trunk to form a thin board W; the thin board W skinned to a predetermined thickness is dried, and a predetermined number of boards are laminated; the temperature of the boards W is raised, and the laminated boards W are compressed together by applying compressing force in a direction orthogonal to the surface of the boards W; and the boards are joined as a laminated board PW. Further, for the joint composition, a surface of the thin board W skinned to the predetermined thickness is used as a joining surface having an adhesive function, and the plural thin boards W are used as resin and sugar components, both contained in the oil palm trunk WD itself, by controlling the temperature and the compressing force of the plural thin boards W.;COPYRIGHT: (C)2014,JPO&INPIT
