Lignocellulosic biomass from grapevines as raw material for particleboard production

Uploaded data presents results of research on mechanical and physical properties of particleboards made with the addition of pruned material from the grapevines – vine pruning waste.

The hypothesis of the study assumes that vine pruning waste may be successfully applied as an alternative feedstock in particleboard production.

The investigation included 8 variants:
A – particleboard with density 650 kg/m3, without particles from vine pruning;
B – particleboard with density 650 kg/m3, with 25% share of particles from vine pruning;
C – particleboard with density 650 kg/m3, with 50% share of particles from vine pruning;
D – particleboard with density 650 kg/m3, with 100% share of particles from vine pruning;
E – particleboard with density 550 kg/m3, without particles from vine pruning;
F – particleboard with density 550 kg/m3, with 25% share of particles from vine pruning;
G – particleboard with density 550 kg/m3, with 50% share of particles from vine pruning;
H – particleboard with density 550 kg/m3, with 100% share of particles from vine pruning.

The following mechanical properties of manufactured composites were tested: modulus of rapture (MOR) and modulus of elasticity (MOE) were tested based on the EN 310 standard; internal bound (IB) according to EN 319 standard, and physical properties of manufactured composites: thickness swelling and water absorption after 2 and 24 hours of soaking in water. Additionally susceptibility to drilling was tested. Each test was repeated at least 10 times.

The results revealed that the share of vine pruning waste is one of the main factors determining the strength properties of manufactured boards. It affected both the mat thickening process as well as the reduction of strength properties. The results showed that the 50% share of vine pruning waste enables the production of boards that meet the minimum requirements of strength properties specified in the EN 312 standard for boards with a density of 650 kg/m3. However, boards with a density of 550 kg/m3 entirely made with vine pruning waste met the minimum requirements of strength properties specified in the standard EN 16368. In addition, the share of pruned material reduces swelling and water absorption after 2 and 24 hours soaking in water. The share of vine pruning waste reduced axial forces during drilling.

本上传数据集呈现了添加葡萄藤修剪废弃物（vine pruning waste）制备的刨花板的力学与物理性能研究成果。
本研究提出的核心假设为：葡萄藤修剪废弃物可作为替代原料，成功应用于刨花板的生产制备过程中。
本次研究共设置8组试验组：
A组：密度为650 kg/m³的刨花板，未添加葡萄藤修剪废弃物颗粒；
B组：密度为650 kg/m³的刨花板，添加25%比例的葡萄藤修剪废弃物颗粒；
C组：密度为650 kg/m³的刨花板，添加50%比例的葡萄藤修剪废弃物颗粒；
D组：密度为650 kg/m³的刨花板，添加100%比例的葡萄藤修剪废弃物颗粒；
E组：密度为550 kg/m³的刨花板，未添加葡萄藤修剪废弃物颗粒；
F组：密度为550 kg/m³的刨花板，添加25%比例的葡萄藤修剪废弃物颗粒；
G组：密度为550 kg/m³的刨花板，添加50%比例的葡萄藤修剪废弃物颗粒；
H组：密度为550 kg/m³的刨花板，添加100%比例的葡萄藤修剪废弃物颗粒。
本次测试对制备的复合材料开展了以下性能检测：依据EN 310标准检测抗弯强度（modulus of rapture, MOR）与弹性模量（modulus of elasticity, MOE）；依据EN 319标准检测内结合强度（internal bond, IB）；同时检测复合材料的物理性能：浸水2小时与24小时后的厚度膨胀率与吸水率。此外还测试了材料的钻孔加工性能。每项测试均重复至少10次。
研究结果表明，葡萄藤修剪废弃物的添加比例是影响刨花板强度性能的核心因素之一，其既会对板坯增厚工艺产生影响，同时也会导致强度性能降低。结果显示，当葡萄藤修剪废弃物添加比例为50%时，可制备出符合EN 312标准对密度650 kg/m³刨花板强度性能最低要求的板材。而完全采用葡萄藤修剪废弃物制备的密度550 kg/m³刨花板，则符合EN 16368标准规定的强度性能最低要求。此外，添加葡萄藤修剪物料可降低板材浸水2小时与24小时后的厚度膨胀率与吸水率。同时，葡萄藤修剪废弃物的添加比例可降低钻孔过程中的轴向受力。
