Impact of Hot-Pressing Parameters and Climate Temperature on VOC Emission from Particleboard

Volatile organic compounds (VOCs) emitted from larch particleboard at different temperatures were studied in this paper. The small climate chamber and portable VOC gas monitor were used to measure VOCs quantities. Particleboard 1 (with hot-pressing time 3.5 min and hot-pressing pressure 35 MPa) and particleboard 2 (with hot-pressing time 2.7 min and hot-pressing pressure 30 MPa) were respectively examined at climate temperatures of 15, 23, 25, and 35°C. At a temperature of 23°C, particleboard 1 showed a higher initial emission than particleboard 2. VOC emissions from particleboards at 35°C were higher than ones at other temperatures. The emission study shows that hot-pressing parameters of particleboard and climate temperature have obvious effect on VOC emission. With the extension of hot-pressing time and the increase of hot-pressing pressure, VOC emissions increase. The increase of temperature can accelerate VOC emissions. On the other hand, temperature markedly affects the short-term emissions and it has less impact on the long-term emissions.
