Effect of Microwave Treatment on Permeability of Populus Deltoides BARTR. Wood

Low permeability of many wood species causes problems during timber drying as well as impregnating with preservatives and resins. Microwave (MW) technology provides solutions to many of these problems. Microwave (MW) treatment influence heartwood permeability and improves preservative distribution and uptake. The effects of microwave radiation time and initial wood moisture content (MC) on the permeability of Populus deltoides Bartr wood specimens after microwave treatment were studied. The experimental study of MW treatment at 2.45 GHz frequency, 64.4 Wcm^-2 intensity and dipping in preservative revealed a remarkable increase in wood permeability.
