초록

마이크로웨이브에 감응하는 주요물질인 Li와 Zn계 전구체를 다양한 조건별로 혼합 및 열처리하여 유전발열소재 (dielectric heating materials)를 제조하였다. 제조된 발열소재의 표면 형태 등의 변화를 SEM 분석으로 확인하였으며 기공구조, 열처리 단계 그리고 표면에 형성되어 있는 Li5Fe5O8 물질이 발열성능에 주요한 영향인자임을 확인하였다. 또한 슬러지 건조 장치에 발열소재가 적용되었을 경우와 그렇지 않은 경우 25%의 함수율을 갖는 슬러지가 각각 6.34%, 15.22%로 건조되어 슬러지 수분 제거효율이 58.34% 상승하였음을 확인하였다. 이에 따라 발열소재가 마이크로웨이브 건조 공정의 성능 및 효율에 직접적인 영향을 미칠 수 있음을 확인하였다.

Dielectric heating materials were prepared through the thermal treatment for composites of Li and Zn type precursors that are major materials being responded to microwave under diversified conditions. The prepared heating material samples were analyzed by SEM and it was confirmed that Li5Fe5O8 materials being formed on the surface was a major influencing factor for the heating performance. Heating materials improved the moisture removal in a sludge drying facility, for example, the moisture content of 25 v/v% sludge decreased to 15.22 v/v%. Accordingly, heating materials were confirmed to directly affect the performance and efficiency of the microwave drying process.
