摘要

本文論述了竹材、意大利楊複合定向粒片板的尺寸穩定性、就膠種、刨花厚度、竹材所佔比率、板密度、板呸結構、用膠量。原料酸性等諸因子對板材吸濕性、尺寸穩定性的影響進行了研究。結果表明。（1）隨板密度增大，板吸濕線膨脹呈增高趨勢；（2）隨著混合材中竹材所占比例的增多，混合材定向粒片板尺寸穩定性改善；（3）原料酸含量越多，酚醛膠板吸水厚度膨脹率越大；pH值大之原料所製造的定向粒片板，其吸濕率較低，有利于降低板子的吸濕線膨脹。

The purpose of this research is to study the dimensional stabiliy of the oriented strand of compositeboard (OSB) made from bamboo and Italian fast-growing poplar, and the effects of resin type, strand thickness, ratio of bamboo strand, board density, mat structure, glue level, bamboo and the acidity of material etc. on the composite OSB were analyzed. The results showed: (1)increasing the board density could increase the LE (Linear expension) of the board and reduce the TS (Thickness swelling) of the board; (2)raising the ratio of bamboo strand could improve the dimensional stability of the OSB board; (3)the thickness swelling of the board made with PF resin could be raised as the acidity was increased , however the water adsorption of composits OSB made of higher PH value was lower and suitable to decrease Linear expansion of the board.
