Abstract
PURPOSE: To reduce the heating time and remove the internal stress in order to increase the percentage of good product by heating wood from the inside at the specified water content using a dielectric heating method.
CONSTITUTION: The adequate water contents to remove the internal stress of woods using the dielectric heating is at least over the air drying water content and desirably a little under the fiber saturation point. An example of the dielectric heating is achieved covering the wood surface with a heat-resistance sheet. It is recommended to heat the wood over 40°C for the specified time using the dielectric heating in order to prevent oozing of resin from the wood. The water content is indicated with the percent value of the water weight in the wood divided by the dry weight of the wood. The air drying water content is defined as the water content of wood reached a stable value placed under the normal field condition for a long time; it depends on the place and the season. The fiber saturation point is defined as the water content at the condition that the wood contains saturated bound water in the fiber cells.
