摘要：把定向结构板(OSB)视为由压缩木、胶压木和石腊改性木三部分组成,分别分析了压缩木和胶压木吸水厚度膨胀率(TS)的变化规律,并探讨了OSB板吸水厚度膨胀率来源的大小。结果表明:常规喷胶工艺制造的OSB板,当TS>26%时,可认为板材刨花界面有部分发生了开裂;当12%In order to study the regulation of TS, setting up new model of orient strand board （OSB）,OSB consists of three parts： compregneted wood, compressed wood, and the wood treated by wax. The TS is affected by three parts together, and the TS of the two parts are analyzed respectively. The results show that when TS〉26%, the interface of flakes is separated, when 12%〈TS〈26%, the interface of flakes is connected and the dimension of OSB is stable by resins in some content, when TS 〈 12% not only the interface of flakes is connected well, but also the dimension of OSB is stable.
