Adsoprtion Characteristic of Fancy Veneer Overlaid Charcoal Board Composite*1

This study was carried out to manufacture very thin natural elm veneer overlaid charcoal board for en-hancing aesthetic value of charcoal board for the indoor application, and to use the advantageous proper-ties of the charcoal as a building material for solving the sick house problem. The thin elm veneer had 26.9 % opening ratio. The experiment results showed that the spreading area and the nonvolatile content of adhesive did not affect the gas adsoprtion of fancy veneer overlaid charcoal board. The natural thin elm veneer overlaid charcoal board enhanced not only the aesthetic beauty but also showed the same gas adsorption by the charcoal board
