Abstract
The influence of hot-pressing parameters on formaldehyde and other volatile organic compounds (VOC) were studied in this paper. The particleboard of larix gmelinii and UF resin were used as main raw materials. Orthogonal design was adopted to analyze the influence of hot-pressing temperature, time, resin and density on the concentration of formaldehyde and other VOC. The results showed that the emission of formaldehyde and other VOC were significantly affected by hot-pressing temperature, time, resin and density. The emission of formaldehyde and other VOC were obviously decreased in usage with the increasing of hot-pressing temperature, press time and the decreasing of density. Taking formaldehyde and other VOC emission into account, the optimized condition was hot-pressing temperature of 180°C, press time of 5 min, resin content of 11%, board density of 0.6g/cm3. The emissions of optimized particleboard satisfied the national standard GB18580-2001.
