1 引言南洋楹(Albizia falcata)是热带地区速生但较少利用的树种之一。其木材很轻,密度为240～490kg/m~3。根据木材的强度和耐久性被列为劣质建筑材料。更有效地开发和利用南洋楹木材是主要的研究内容之一。利用南洋楹木材生产刨花板标志着劣质材的利用范围扩大。利用南洋楹木材作为刨花板的原料已有过报道。我们以前的试验表明,利用南洋楹木材制成的低密度刨花板作为结构材,某些性能是优良的。但板子的尺寸稳定性差,胶合困难。刨花的形状和尺寸对板子的性能也
1 Introduction Albizia falcata is one of the fast growing but less utilized species in the tropics. The wood is very light, the density of 240 ~ 490kg / m ~ 3. According to the strength and durability of wood was classified as poor quality building materials. Developing and utilizing the South China Sea timber more effectively is one of the main research topics. The use of Nanyang wood for the production of particleboard marks the wider use of inferior materials. The use of Nanyang wood as a raw material for particleboard has been reported. Our previous experiments show that some properties are good using low density particle board made of South Pacific sapwood as the structural material. But the board’s dimensional stability is poor, gluing difficult. The shape and size of shavings also have the same performance on the board
