Evaluation of impact factors on emission rate of formaldehyde from MDF based on chamber tests

챔버실험을 통한 MDF에서의 포름알데히드 방출의 영향인자 평가

The purpose of this study was to evaluation of impact factors, which are temperature and relative humidity on formaldehyde emission from MDF(Medium Density Fiberboard). The test was carried out at 4 specimens that were different of temperature and humidity by using small chamber system. Formaldehyde was sampled and analyzed by HPLC. The results of this study were as follows; 1) When the temperature increased from 25 to $35^{\circ}C$ at 50%, the emission rate of formaldehyde increased 1.0-1.6 times. 2) When the RH increased from 50% to 80% at $25^{\circ}C$, the emission rate of formaldehyde decreased 0.6 times. 3) The enhancement effect of temperature on Formaldehyde under RH of 50% was more significant than under RH of 80%.
