도시 폐기물 폐목재의 건조 특성
Drying Characteristics of Municipal Wood Waste
본 연구는 질소 분위기의 등온 열중량 분석기를 사용하여 도시 폐기물 폐목재 시료 wood, particle board, MDF의 건조특성을 측정 및 고찰하였다. 폐목재의 건조속도는 잔류 수분 분율에 대한 1차 반응속도로 잘 표현되었다. 건조 활성화 에너지는 12.72~18.31 kJ/g mol, 빈도인자는 0.2155~1.249 1/s이었다.
This study investigated and discussed the drying characteristics of municipal wood wastes (wood, particle board, medium density fiber-board(MDF)) in the N2 environment with an isothermal thermogravimetric analyzer. The drying rate could be expressed by a first order reaction model on remaining fraction of moisture. The activation energy ranged from 12.72 kJ/g mol to 18.31 kJ/g mol and the frequency factor from 0.2155 1/s to 1.249 1/s.
