The objective of this study was to investigate some physical/mechanical properties and formaldehyde emission of particleboard containing particles of waste stone pine cone at various usage ratios using urea-formaldehyde resin. Some physical (thickness swelling, water absorption), mechanical (modulus of elasticity, modulus of rupture, internal bond strength) properties and formaldehyde emission of particleboards were evaluated. The addition of cone particle improved water resistance of the panels and greatly reduced their formaldehyde emissions. However, flexural properties and internal bond strength decreased with increasing cone particle content in the panel. The cone of the stone pine can be considered as an alternative to wood material in the manufacture of particleboard used in indoor environment due to lower thickness swelling, water absorption and formaldehyde emission.
本研究的目的是使用脲醛树脂，研究不同使用比例下含有废弃石松果颗粒的刨花板的一些物理/机械性能和甲醛释放量。对刨花板的一些物理性能（厚度膨胀率、吸水率）、机械性能（弹性模量、抗弯强度、内结合强度）和甲醛释放量进行了评估。添加松果颗粒提高了板材的耐水性，并大大降低了它们的甲醛释放量。然而，随着板材中松果颗粒含量的增加，其弯曲性能和内结合强度下降。由于较低的厚度膨胀率、吸水率和甲醛释放量，石松果可被视为室内环境中使用的刨花板制造中木材材料的替代品。
