摘要: 
The sap. and heartwood of Japanese fir from thinnings middle and small
diameter logwere separated to prepare as particles, which bonded with isocyanate glue
to made particleboards. Their MOR @ IB and screw holding strength increased with
the densi

以柳杉疏伐中小徑木之心材及邊材當作粒片材料。而製造異氰酸鹽粒片
板。其靜曲強度、內聚強度及木螺絲釘保持力均隨粒片板密度增加而上升,心材
粒片板僅於靜曲強度呈較高之現象,其他兩性質之差異不明顯。厚度膨脹率亦隨
粒片板密度增加而增大.吸水率則反之;尺寸安定性上之線性總變化及厚度總變
化,亦均隨粒片板密度增加而增加。當心材與邊材原料對粒片板線性安定性影響
不顯著時.而卻在粒片板厚度安定性上,以心材粒片板較佳。
