不同比例麦叶、穗轴对定向结构麦秸板性能的影响

Effects of the Different Proportions of Wheat Leaf and Rachis on the Performance of OSSB

以麦秸、麦叶及穗轴为原料,压制含有不同比例麦叶、穗轴的定向结构麦秸板,测定各板材的物理力学性能,分析麦叶、穗轴对板材性能的影响。结果表明:随着麦叶、穗轴含量的增大,板材的吸水厚度膨胀率增大,静曲强度、弹性模量和内结合强度均降低。

Different proportions of wheat stalk, rachis and wheat leaf were used to make orented strand straw board （OSSB） to examine the influences of the materials on the performance of the board. The results showed that the thickness swelling rate increased and both the modulus of elastic and modulus of rupture decreased as the contents of rachis and wheat leaf increased.
