韓紙製造工程 中에서 發生하는 백색 슬러지와 흑색 슬러지를 각각 일정비율(10, 20, 30, 40%)로 木材 파티클과 混合하고 PMDI, 요소 및 페놀수지를 이용하여 目標比重 0.60, 0.75, 0.90 별로 複合보드를 製造하여 機械的 性質을 측정한 결과 파티클보드에 韓紙 슬러지를 약 20%까지는 混合하여 複合材를 제조하여도 충분히 可能하리라 믿어진다. This research was carried out to develop the Hanji(Korean paper) sludge·wood particle composite utilizing the waste sludges occurring from the making process of Hanji(Korean paper). At the research, four mixing ratios of white or black sludge to wood particle(10:90, 20:80, 30:70 and 40:60), three types of the resin adhesives(PMDI, urea and phenol resin) and three levels of the densities(0.60, 0.75 and 0.90) were designed to investigate the mechanical properties of Hanji(Korean paper) sludge·wood particle composite.In the white and black sludge·wood particle composites, bending properties(MOR, MOE) showed the decreasing tendency according to the increase of sludge additive, but it was clearly increased with the increase of specific gravity. Also tensile strength had the same tendency as in these bending properties. The internal bond strength of white sludge․wood particle composite had no tendency, but that of black sludge․wood particle composite was decreased as an increase of Hanji sludge additive.
