Change in Surface Temperature of Woodceramics Manufactured by Sawdust Boards - Effect of the Rate of Resin Impregnation and Burning Temperature -

톱밥보드로 제조된 우드세라믹의 표면온도 변화 - 수지 함침율과 소성온도의 영향 -

Using woodceramics made from sawdust board of Larix leptolepis thinning logs, change in surface temperature were investigated, by the rate of resin impregnation and burning temperature. As the surface temperature of silicon rubber heater was going up, that of woodceramics also increase rapidly. Woodceramics made from under the condition of the rate of resin impregnation 70-80% and burning temperature 800-$1000^{\circ}C$, were higher than that of surface temperature. Also, it was found that woodceramics maintained heat for a long time because the descending velocity of their surface temperature was lower than that of the heater.

낙엽송 간벌재 톱밥보드로 우드세라믹을 제조한 후 수지함침율 및 소성온도에 따른 우드세라믹의 표면온도 변화를 조사하였다. 히터의 표면온도가 증가함에 따라 우드세라믹의 표면온도도 급속히 증가하였으며 수지함침율 70∼80%, 소성온도 800∼1000℃ 조건으로 제조된 우드세라믹의 표면 온도가 상대적으로 높았다. 히터의 표면온도보다 우드세라믹 표면온도의 하강속도가 느려 우드세라믹이 오랜 시간 열을 유지하고 있음을 알 수 있었다.
