Abstract

The sizeable global production of wood-based products requires new sources of raw material, but also creates large quantities of wastes or composites that do not comply with requirements. In this study, the influence of different shares of recovered high-density fiberboards (HDF-r), reversed into the production, on industrial HDF properties, has been examined. HDF-r may be a suitable partial substitute for raw pinewood for industrial HDF production. Although most of the mechanical properties, as well as thickness swelling and water absorption, had a linear decrease with the increase in the share of HDF-r share, the elaborated boards met most of the commercial requirements (EN 622-5). The property that did not meet the requirements was the internal bond strength for panels with 10% of HDF-r. The presented results show that, after some adjustments, it should be possible to produce HDF boards with up to 10% of recycled HDF being able to meet all commercial requirements.

摘要

全球大量生产木质产品既需要新的原材料来源，也会产生大量不符合要求的废料或复合材料。在本研究中，已考察了将回收的高密度纤维板（HDF-r）以不同比例重新投入生产对工业用高密度纤维板性能的影响。HDF-r可能是工业用高密度纤维板生产中松木原料的合适部分替代品。尽管随着HDF-r比例的增加，大多数机械性能以及厚度膨胀率和吸水率呈线性下降，但制成的板材满足了大部分商业要求（EN 622-5）。不符合要求的性能是含10% HDF-r的板材的内结合强度。给出的结果表明，经过一些调整后，应该能够生产出含高达10%回收HDF且能满足所有商业要求的高密度纤维板。
