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。

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 different Hot-pressing method were different.
