摘要

对杨木水泥刨花板的物理力学性能与主要工艺参数——密度、木灰比、水灰比、添加剂及添加量的关系作了研究。结果表明,密度（D）对板材性能影响最大,木灰比（W/C）次之,水灰比（W,1,/C）最小;板材的主要性能如MOR、MOE、IB同密度、木灰比、水灰比的关系,可用方程Y=a,0,+a,1,D+a,2,（W/C）+a,3,（W/C）,2,+a,4,（W,1,/C）+a,5,（W,1,/C）,2,表示;在各种添加剂中,以氯化钙的效果最好。

Abstract

The relationships between the physical and mechanical properties of wood cement particleboard made from poplar and the technological parameters: density, wood/cement ratio, water/cement ratio, additive and additive′s amount were studied. The results showed that among the density, wood/cement ratio, water/cement ratio, density had the largest influences on board′s properties; wood/cement ratio was the second, and the water/cement ratio had the least. The board′s properties such as MOR, MOE, IB could be described by density （D.）, wood/cement ratio （W/C）, water/cement ratio （W,1,/C）with the following equation, Y=a,0,+a,1,D+a,2,（W/C）+a,3,（W/C）,2,+a,4,（W,1,/C）+a,5,（W,1,/C）,2,. Among the three additives, the results of adding. CaCl,2,was the best.
