Abstract
Laboratory particleboards (PBs) were made with urea-formaldehyde (UF) resins at four press times and two resin application rates. Enclosed caul system was used for collecting the exhaust gases materials generated during the hot-pressing of PB. Exhaust gases materials generated inside the enclosed caul during the hot-pressing of PB were collected in a controlled air stream. Formaldehyde from the exhaust gases collected was determined per a chromotropic method of the National Institute of Occupational Safety and Health Method 3500. The test results showed that formaldehyde emissions during the hot-pressing of PB increased with increasing press time, UF resin mole ratio, and resin application rate.
포름알데히드와 요소의 몰비가 다른 2종류의 요소수지 접착제를 이용하여 접착제 첨가량과 열압시간 등 여러 조건에서 실험실 파티클보드를 열압하는 동안 배출되는 가스를 중류수에 용해 포집하고, 이렇게 얻어진 용액으로부터 포름알데히드 배출량을 미국 National Institute of Occupational Safety and Health (NIOSH) 3500의 방법에 의해 분석 비교하였다. 평가된 결과는 파티클보드를 열압하는 동안 배출되는 가스 중에서 포름알데히드량은 요소수지의 종류, 접착제 첨가량과 열압시간에 의해서 영향을 받는다는 것을 보여준다.
