Discarded Furniture Panels with Different Densities and Resin Contents

Abstract This study evaluated the quality of the particleboard produced with particles generated from mobile discharges with mixture of equal parts of industrial particles of Pinus. The material was collected and processed in the form of chips by a company specialized in waste recycling. The experimental plan consisted in producing panels with nominal density 0.55, 0.70 and 0.85 g/cm3, and urea-formaldehyde resin of 8, 10 and 12%. The increased density and resin content contributed to improve the physical and mechanical properties of the panels. The panels produced with nominal density of 0.70 and 0.85 g/cm3, and 10% resin content, showed better feasibility of using mobile discharges particles in a proportion of 50% mixture with particles of Pinus industrial production of particleboards.

摘要 本研究评估了以等量松木工业颗粒与流动出料产生的颗粒混合制备的刨花板（particleboard）的质量。该原料由一家专注于废弃物回收利用的企业收集并加工为木片形态。实验方案为制备标称密度分别为0.55、0.70及0.85 g/cm³，且脲醛树脂（urea-formaldehyde resin）添加比例为8%、10%及12%的刨花板。提升板材标称密度与树脂添加比例，可有效改善刨花板的物理与力学性能。其中标称密度为0.70、0.85 g/cm³且树脂添加比例为10%的刨花板，展现出将50%占比的流动出料颗粒与松木工业颗粒混合制备刨花板的更佳应用可行性。
