ADSORPTION AND SOUND ABSORPTION STRUCTURE OF ACTIVATED CARBON BOARD-WOOD COMPOSITE OVERLAID WITH NATURAL WOOD FINISH FOR INDOOR AIR QUALITY, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to an adsorption and sound absorption structure, and preparation of a charcoal board-wood composite overlaid with a natural wood finish comprising the same, wherein a specific adsorption structure is provided to the wood material, which is a rear board and a surface board, so as to allow one surface or both surfaces of an activated carbon board or a charcoal board, a central board placed in a central layer of an activated carbon board-wood composite, to show adsorptive properties, thereby adsorbing the Radon gas escaping from a concrete wall or the base of a building onto the wall-side surface of the activated carbon board or the charcoal board through the control of a suitable minimum perforation rate and arrangement of the rear plate and the connection structure with a hidden wider adsorption chamber of the central board, and adsorbing various gases generated indoors onto the indoor-side surface of the activated carbon board through the structure of a wider adsorption chamber of the activated carbon board of the central board connected to the indoor-side surface using suitable line type grooving of the surface board while simultaneously enabling sound absorption.
