| 摘 要： | 分别采用普通热压和喷蒸热压2种热压方法制备了无胶烟秆碎料板,对它们的物理力学性能进行了对比研究与分析。结果发现,与普通热压法相比,喷蒸热压法制备的无胶烟秆碎料板的静曲强度、弹性模量与内结合强度明显提高,吸水厚度膨胀率显著减小,其原因可能是不同热压过程中烟秆碎料发生了化学变化。

| Abstract: | Tobacco stem binderless particleboard was prepared by ordinary hot-pressing and steam injection hot-pressing respectively,and mechanical properties of particleboard with different hot-pressing method was studied and analyzed.The results showed that,compared with ordinary hot-pressing,MOR,MOE and IB of the tobacco stem binderless particleboard with steam injection hot-pressing increased significantly;TS decreased significantly.The possible reason was that chemical changes of tobacco stem particles with diffe... |
