Abstract

This study was investigated the properties of boards prepared from woody of Broussonetia Kazinoki differed in density of board and mixed quantity of powdered phenolic resin. Water absorption decreased as the density of boards and resin content increased, but bending strength and brinell hardness increased as the density of board and the quantity of resin added increased. Thickness swelling increased as the density of boards went up, and that, in contrary, decreased as the quantity of resin added to the boards.

인피섬유로 한지를 제조하고 남은 닥나무 목질부를 활용하기위한 방안으로 닥나무 목질부 파티클을 이용하여 보드를 제조하고 밀도 및 수지첨가량에 따른 물성을 검토하였다. 흡수율은 보드의 밀도 및 수지첨가량이 증가할수록 감소하였으며, 휨강도 및 Brinell 경도는 밀도 및 수지첨가량이 증가할수록 세포간 결합력이 커져 증가하였다. 흡수 두께 팽창율은 보드의 밀도가 증가함에 따라 증가하였고, 수지첨가량이 증가할수록 감소하였다.
