Effect Of Panel Area-Volume Ratio On Tvoc Released From Decorative Particleboards

Home renovation can improve our living environment, but it can cause pollution and endanger human health. Wood-based panels area main source of polluting volatile organic compounds (VOCs). This article studied the VOC concentration of different types of decorative particleboards (PBs) and different panel area-volume ratio, and the effect of panel area-volume ratio on release of various substances. In this study, the main experimental conditions are as follows: the temperature was controlled at 23 +/- 0.5 degrees C; the humidity was controlled at 50% +/- 3%; and the rate of ventilation was controlled at once 1 h. And a 15-L small-environmental chamber was used to test the VOC emission. The experimental material was PB with different decorative materials (water-based paint, melamine-impregnated paper, polyvinyl chloride, and PB with no decorative material), and VOC emission was collected under different panel area-volume ratios (1, 1.5, 2, and 2.5 m(2)/m(3)). The result showed that the VOCs were present, with the trend of decreasing with time. The decline velocity of water-based paint (WP) was the fastest, whereas that of the PB with no decorative material was the slowest. Increase of panel area-volume ratio could cause the VOC concentration to increase, but the panel area-volume ratio does not have a linear relationship with VOC concentration. Surface decoration can reduce the release of various kinds of material inside the plate to a certain extent. Melamine impregnated paper (MI) and polyvinyl chloride (PVC) can reduce the release of aromatic hydrocarbons in panels, and PVC can inhibit the release of esters in panels.
