Abstract

The physical and mechanical properties of sawdust-rice husk mixed ceramic were investigated with rice husk mixing ratios. The mixed ceramic board was produced with carbonization and resin impregnated sawdust-rice husk board at high temperature. At the same percentage of resin impregnation condition, density and bending strength of the mixed ceramic board increased with increasing the mixing rates of rice husk, whereas weight loss of the ceramic boards decreased. At the same temperature condition for the carbonization of resin impregnated sawdust-rice husk board, the density and bending strength were the highest with 40% of rice husk mixing ratio.

제재과정에서 발생되는 톱밥과 농업부산물인 왕겨의 활용방안을 찾고자 왕겨의 혼합비율에 따라 혼합보드를 제조하고 수지함침 및 탄화과정을 거쳐 혼합세라믹을 제조하여 왕겨의 혼합비율에 따라 물성을 조사하였다. 같은 수지함침율에서 왕겨혼합비율이 증가함에 따라 탄화 후 밀도 및 휨강도는 증가하였으나 중량감소율은 감소하였다. 또한 같은 탄화온도에서 밀도와 휨강도는 왕겨혼합비율이 40%일 때 가장 큰 것으로 나타났다.
