Abstract

This study presents opportunities for the utilization of timber by-products with defects for manufacturing engineered wood panels. Three gluing methods were proposed for this waste raw material derived from Scots pine (Pinus sylvestris L.) wood. The methods used for combining and gluing enabled a more complete and complex utilization of wood with defects. The physical properties (density and moisture content) and mechanical properties (bending strength and modulus of elasticity) of the laboratory-fabricated engineered wood panels were evaluated in accordance with the European standards. The highest density of 643 kg/m3 and bending strength values (28.6 N/mm2) were obtained from the panels manufactured using method 3 and veneered with beech veneer sheets. The modulus of elasticity of the laboratory-made engineered wood panels reached values of up to 5580 N/mm2. This study demonstrated the feasibility of the utilization of defective wood pieces in the manufacturing of engineered wood panels.
利用樟子松
这项研究提出了利用有缺陷的木材副产品制造工程木板的机会。针对这一源自苏格兰松木的废弃原料,提出了三种胶合方法。结合和粘合的方法使有缺陷的木材得到了更全面、更复杂的利用。根据欧洲标准对实验室制造的工程木板的物理性能(密度和含水率)和机械性能(弯曲强度和弹性模量)进行了评估。使用方法3制造并贴有山毛榉贴面板的面板获得了最高密度643 kg/m3和抗弯强度值(28.6 N/mm2)。实验室制造的工程木板的弹性模量达到了5580 N/mm2的值。本研究证明了利用有缺陷的木片制造工程木板的可行性。
