초록
Specimens of seven hardwood species were heat-treated at three temperature levels of 170, 190 and 210°C. Their FSP’s were measured by the volumetric swelling method and compared with the control’s. Within a species the FSP decreases as the temperature of heat treatment increases. The FSP’s of the controls range from 26.1 to 29.6%, while those of the specimens heat-treated at 210°C from 16.9 to 21.8%. There were no difference of basic density between the heat-treated and control specimens. The color indexes of ash and beech specimens were measured using a colorimeter. It was revealed that the temperature of heat treatment affected on the color more than the treatment time.
