Abstract

The invention discloses a modification processing process for oil palm wood trunks. The process comprises the steps: (1) selecting materials, wherein fresh and corrosion-free oil palm wood trunks with a diameter at the breast height larger than 30mm are selected to serve as raw materials; (2) cutting the raw materials, wherein the raw materials are cut to the length of 2500mm to serve as trunk raw materials; (3) removing the surface, wherein bark of the trunk raw materials in the step is planned clean (2); (4) carrying out antiseptic treatment and adhesive compression; (5) sawing or cutting the trunk raw materials in a rotary mode, wherein the trunk raw materials discharged through a pressure tank in the step (4) are sawn or sliced into plates of various thicknesses; (6) drying the plates, wherein the plates obtained in the step (5) are dried to be with the water content ranging from 13 percent to 16 percent; (7) carrying out hot pressing, wherein the plates dried in the step (6) are pressurized at the temperature of 150 DEG C with pressure of 1200 tons for five minutes to form a finished product with the required thickness.

Description

technical field [0001] The invention relates to the field of reutilization of oil palm trunks, in particular to a modification process of oil palm trunks and an oil palm board prepared by the modification process. Background technique [0002] Because the utilization of the trunks of oil palm trees is basically blank at present, a large number of eliminated trunks become agricultural waste, and there is an urgent need for the wood processing industry to turn waste into treasure, and turn abandoned oil palm trunks into high-quality timber; solve a large number of problems in the society needs; [0003] The reason for the blank use of oil palm trunks is that the oil palm trunks contain a lot of water, about 70%, and have no weight after drying, and the structure is loose, especially the horizontal structure is a powdery structure. Therefore, it cannot form a board that can be used practically. [0004] In order to solve the reuse of oil palm wood, the applicant of this case ...
