초록

폐목재를 고온고압장치를 사용하여 나무의 결대로 파쇄 후 건축재료로의 활용을 위하여 등급별로 분류하여 열분해 및 파쇄특성을 알아보았다. 그 결과, TG/DTA 그래프에서 $250^{\circ}C$에서 급격한 무게감소가 발생하는데, 건축재료로의 활용을 위해서는 $250^{\circ}C$이하의 온도에서 처리가 되어야 한다. 고압파쇄 실험결과 활엽수보다는 침엽수가 나무의 결대로 잘 찢어짐을 알 수 있었으며, 그 중 편백나무(W-7)가 가장 양호한 결과를 나타내었다. 다양한 조건의 실험결과, 온도는 $200^{\circ}C$, 압력은3MPa이 최적조건임을 확인할 수 있었다.

The purpose of this research was to see thermal and breaking type characteristics of waste wood for construction materials using high temperature and pressure equipment. In TG/DTA graph weight of waste wood was steeply decreased at $250^{\circ}C$, it has to be treated below $250^{\circ}C$ for construction materials. In popping test the needle-leaved tree was more broken in texture than the broad-leaved tree, especially, Chamaecyparis obtusa(W-7) was the best. The optimum result was obtained at temp. $200^{\circ}C$, pressure 3MPa among the experimental condition.
