摘要

本研究探讨了千层木皮被制成可持续工程木制品的潜力。板是由M. rhaphiophylla树皮热压制造的,没有使用任何额外的粘合剂或其他化学处理。在90°C、120°C、150°C、180°C和195°C的温度和1、2和3 MPa的压力下,对树皮片进行20分钟的压制。对试件进行三点弯曲、吸水和阻抗管测试,测定其断裂模量(MoR)、弹性模量(MoE)、厚度膨胀、吸水率和吸声势。采用线性混合效应(LME)模型确定树皮状态和热压参数与最终板性能之间的相关性。发现板材的MoR, MoE和厚度膨胀性能与其他基于树皮的替代品相似或优于。吸水率与市售胶合板和中密度纤维板(MDF)对照材料相似,吸声率较高,但MoR和MoE较低。木犀草树皮板显示出作为中密度纤维板和胶合板的合适替代品的潜力,包括在橱柜或贴面板上的进一步发展。

Adhesive free Melaleuca rhaphiophylla (Swamp Paperbark) bark as an engineered wood product

This study investigated the potential for Melaleuca rhaphiophylla bark to be made into a sustainable engineered wood product. Boards were manufactured from M. rhaphiophylla bark by hot pressing them without the use of any additional binders or other chemical treatments. Sheets of bark were pressed for 20 min at temperatures of 90 °C, 120 °C, 150 °C, 180 °C and 195 °C and pressures of 1, 2 and 3 MPa. Samples of the boards underwent three-point bending, water absorption and impedance tube testing to determine their Modulus of Rupture (MoR), Modulus of Elasticity (MoE), thickness swelling, water absorption and sound absorption potential. Linear mixed effects (LME) models were used to identify correlations between the condition of the bark and hot-pressing parameters with the properties of the final boards. The MoR, MoE and thickness swelling properties of the boards were found to be similar or superior to other bark-based alternatives. Water absorption was similar to commercially available plywood and medium density fibreboard (MDF) control materials, sound absorption was higher, but MoR and MoE were lower. M. rhaphiophylla bark boards show potential to be suitable alternatives for medium density fibreboard and plywood including uses in cabinetry or veneers with further development.

期刊介绍: European Journal of Wood and Wood Products reports on original research and new developments in the field of wood and wood products and their biological, chemical, physical as well as mechanical and technological properties, processes and uses. Subjects range from roundwood to wood based products, composite materials and structural applications, with related jointing techniques. Moreover, it deals with wood as a chemical raw material, source of energy as well as with inter-disciplinary aspects of environmental assessment and international markets. European Journal of Wood and Wood Products aims at promoting international scientific communication and transfer of new technologies from research into practice.
