Low VOC drying of lumber and wood panel products. Progress report number 6
Abstract
Twenty five Southern pine boards were machined into 2 x 4 inch pieces. Next, the 8 foot boards were cut in half into matched pairs. One of the two was irradiated with RF, while the other served as a control. Both sets were dried under a conventional temperature-time based schedule. Results and conclusions are: RF pretreatment of lumber does not affect strength; the amount of pinene lost into the headspace during low-VOC RF-treatment of wood approximately corresponds to the amount of material lost from the wood; virtually all the pinene can be removed from the low-VOC reactor with steam, suggesting that pinene can be collected when the small amount of steam released during low-headspace treatment is condensed; temperature and moisture loss profiles for particle at 105 C has been modeled using experimental data at 130 C and 160 C; the VOC-temperature curve from dried particle shows a break at about 156 C, the boiling point of {alpha}-pinene, demonstrating that pinene boil-off occurs beyond this threshold; VOC release from dry particle has been successfully modeled; the transport of VOC from sapwood to the atmosphere for pine is faster than the corresponding movement from heartwood to sapwood; and seasonal variations in pinemore »
