Physical-mechanical production and evaluation of medium and high density waste panels

Abstract Brazil has seen a growing number of studies on the use of sawdust from industrial processes for the production of wood panels with added value to minimise forest exploration. In this article, five treatments with mixtures of wood particles from carpentry shops and sugarcane bagasse were examined. For particle homogenisation, granulometric composition studies were conducted; subsequently, three panels were made for each treatment, with the addition of 10% of polyurethane resin from castor oil, and evaluations were performed to determine the physical and mechanical properties of the panels. The physical and mechanical properties obtained with the mixtures with 50% of sawdust and 50% of sugarcane bagasse indicated that the production of panels for indoor use under dry conditions is possible.

摘要：巴西针对利用工业生产过程中产生的锯末制备高附加值木质板材以减少森林采伐的研究日益增多。本文对五种由木工车间木颗粒与甘蔗渣混合而成的处理方案展开研究。为实现颗粒均质化，先开展粒度组成分析；随后针对每种处理方案制备三块板材，添加10%的蓖麻油基聚氨酯树脂，并对板材的物理及力学性能进行测试与评估。当混合配比为50%锯末与50%甘蔗渣时，所得板材的物理与力学性能表明，该类板材可应用于干燥环境下的室内场景。
