【Abstract】 The release of formaldehyde from wood-based boards was studied in a small environmental chamber (0.1 m~3). The effects of temperature, relative humidity and air exchange rate on the emission of formaldehyde were determined. The formaldehyde concentration increased with increasing temperature (20, 25, 30, 35 ℃), increasing humidly (45%, 60% and 80% RH) and decreasing air exchange rate (0.5, 1.0, 1.5 and 10/h).The study results are useful for forecasting indoor formaldehyde concentration, developing valid formaldehyde emission models and minimizing adverse effects of high formaldehyde release of newly finished houses.更多还原
