Abstract

This study investigates the effects of chip type and sawdust percentage on physical and mechanical properties of chip-sawdust boards. The used wood chips varied in linear dimensions and original source. The origin determined the wood quality, which translated into the chips' linear dimensions. The used materials were chips from sawmill waste processing, aggregate processing of sawmill wood, and chips intended for medium-density boards. The experiment demonstrated that the best boards in terms of mechanical properties were obtained from 4-mm-thick chips with 30% sawdust content and a density of 850 kg/m. These boards meet the requirements of the EN 312 (2010) standard for P5 boards.

摘要

本研究调查了木片类型和锯末百分比对木片 - 锯末板物理和机械性能的影响。所使用的木片在线性尺寸和原始来源方面存在差异。来源决定了木材质量，这又转化为木片的线性尺寸。所使用的材料包括锯木厂废料加工产生的木片、锯木厂木材的集料加工产生的木片以及用于中密度板的木片。实验表明，就机械性能而言，最佳板材是由厚度为4毫米、锯末含量为30%且密度为850千克/立方米的木片制成的。这些板材符合EN 312（2010）标准中P5板的要求。
