Abstract

The present study examined the formaldehyde (HCOH) emission characteristic of various wood-based panel used in interior design, and measured changes in formaldehyde emission when a number of VOC reduction methods were applied. Formaldehyde emission showed a clear tendency of increase with the rise of temperature, and the concentration of formaldehyde emitted changed according to the preprocessing condition before measuring. Formaldehyde emission from wood board after bake out treatment was lower than that of the control group. When specimens were coated with urethane, cashew, water, oil stain, they generally showed the decrease of formaldehyde emission, although varying according to finishing material, and when edge sealing was applied the decrease became significant. $TiO_2$ coating was more effective in decreasing formaldehyde under ultraviolet lamps than under ordinary lamps. When the irradiation of ultraviolet lamps gets longer, formaldehyde emission decreased.

본 연구는 각종 실내디자인에 이용되는 목질보드의 포름알데히드(HCOH) 방산 특성과 몇 가지 VOC 저감 방법에 대한 포름알데히드의 방산량 변화를 측정하였다. 포름알데히드 방산량은 온도가 증가함에 따라 뚜렷이 증가하는 경향을 보였고, 측정 전 처리조건에 따라 포름알데히드 방산량의 현저한 변화가 나타났다. bake-out 처리후의 목질보드의 포름알데히드 방산량은 대조구와 비교하여 감소함을 나타냈다. 시편에 urethane, cashew, water stain, oil stain coating을 했을 때 각 마감재료에 따라 포름알데히드 방산량의 차이가 확인되었으며, edge sealing 처리 후 두드러진 감소경향이 나타났다. $TiO_2$ coating은 일반광보다는 자외선 램프의 포름알데히드 저감효율이 좋았고, 자외선 램프의 조사시간이 길어지면 포름알데히드의 감소량도 증가하였다.
