The invention consists of a surface plate made of a back made of a perforated wood material board, activated charcoal board or the center plate made of a charcoal board, and an overlay foil end plate of Plaster of natural wood plastering wood material plate, the center plate from said surface plate line which is half-bent processed to form to a depth of a surface or center of plate-bone or the is characterized in that it comprises the formation of a suction chamber by caused by line-shaped bend processing of the center plate connected to the wall side la tonkatsu and indoor gas If the plates of the double-sided relates to a charcoal board, wood material composite for heupchakreul is perforated with at least 1.5% perforation area ratio with respect to the rear plate overall surface area to the surface of the central panel or to a certain depth of the center plate, and this connection a double perforation or center have the absorption chamber enhanced the exposed area of ​​the center plate with 10% bent bone percentage of the plate, or, and, unlike the perforation rate in accordance with the higher height and a lower predetermined height of the back plate, the surface plate is at least 1.5 with respect to the surface plate overall surface area % the width of the bend formed by the surface area ratio or suction chamber is directed to a surface plate bend goals 10 times wider than the hidden structure of charcoal board wood composite material connected to the surface of the plate to bend processed as bone. As well Absorption Coefficient large a 凹 home line-shaped bend machining a suction chamber structure and this connected, such as at the same time up to half the depth of the activated charcoal board thickness of the surface plates and the central layer of the one charcoal board wood material complex using the properties of high activated carbon since they represent a hidden suction chamber structure and a high absorption Coefficient both large hidden suction chamber structure connected to installing the △-type album Sabu's incoming incident portion through the bend goals of surface plates surface plate bend bone absorption Sound absorption of adsorption and absorbing at the same time It relates to Plaster of natural wood charcoal board wood composite material to form a seal. In addition, a one-step method for producing activated charcoal board / charcoal board manufacturing process and the surface plate, the activated carbon board / charcoal board and the rear address the two processes of the bonding process for manufacturing complexes of the plate in a single hot-press process by energy saving and PMDI adhesive release plate It relates to a method of producing a wood-based material board charcoal composite applying step 4 apbeop series with a non-stick advantages press or the press plates.
