Abstract

This study was carried out to investigate the formaldehyde emission of building materials and effect of carbonized-board (c-board) on formaldehyde reduction using a chamber method. As a result, reduction performance of formaldehyde was in the order of c-board (90%), c-bamboo board (84%), diatomite-based panel (82%), allophane-based tile (78%), Pinus densiflora timber (58%), MDF (54%) and gypsum-based board (46%) for approximately 12 days. In $1.9m^3$ chamber filled with particleboard (PB), the formaldehyde reduction performance of c-board was significantly increased with increasing input amount of c-board for 68 days. In particular, the formaldehyde emissions can be reduced above 40% and 75% by input rate of 10% and 30% c-board, respectively, in given ratio of chamber volume and PB area.

본 연구에서는 각종 건축재료의 폼알데하이드 방출 특성 및 탄화보드에 의한 이들의 저감 효과를 알아보기 위하여 챔버법으로 성능을 분석하였다. 그 결과, 약 12일간 소형 챔버 내에서의 폼알데하이드 저감 성능은 탄화보드(90%), 죽탄보드(84%), 규조토판넬(82%), 알로펜타일(78%), 소나무판재(58%), MDF (54%), 석고보드(46%)의 순으로 나타났다. 또한 파티클보드(PB)로 채워진 $1.9m^3$ 크기의 챔버 내 폼알데하이드 방출량을 68일간 조사한 결과, 탄화보드 투입량이 증가함에 따라 폼알데하이드 방출량은 크게 감소하는 것으로 나타났다. 특히 챔버의 크기 및 PB 면적 대비 탄화보드를 각각 약 10% 및 30% 투입하면 폼알데하이드를 약 40% 및 75% 이상 저감시킬 수 있는 것으로 조사되었다.
