まとめ
ハーゼルナットの木材は,部分的に松の代わりに,板の製造の可能性を示しています. 内部結合強度と回転抵抗を高める一方で,ハゼルの含有量が高くなり,屈折強度が低下し,厚さの膨張が増加し,より広範な使用のために水分抵抗の改善が必要になります.
科学分野:
- 材料科学
- 木材科学
- 持続可能な材料
背景:
- プラスチック板は広く使用されている構造材料です.
- パイン (Pinus sylvestris L.) は一般的な原料である.
- ハーゼルナット (Corylus avellana L.) のような代替木材の探求は,持続可能性と資源の多様化にとって極めて重要です.
研究 の 目的:
- 単層構造板の生産で松の木の部分的または完全な代替品としてハゼルナットの木材の使用の可能性を調査する.
- ハーゼルナッツの木材の含有量によって製造されたパーティクルボードの機械的および物理的性質を評価する.
- ハーゼルナッツの木材ベースのパーチルボードの適性を欧州標準で評価する.
主な方法:
- 薄板は松木を0%, 5%, 10%, 25%, 50%,そして100%で代替したものです.
- 板はフェノル・フォーマルアルデヒド (PF) 樹脂を用いて,目標密度700kgm−3と厚さ13mmであった.
- 機械的な試験 (MOR,MOE,IB,SWR) と物理的な試験 (WA,TS) はヨーロッパ標準に従って実施された.
- 密度プロファイルが分析された.
主要な成果:
- ハーゼルナットの木材の含有量が増加すると,屈折強度 (MOR) と硬度 (MOE) が低下したが,内部結合強度 (IB) とスクルーの引き出し抵抗 (SWR) は改善された.
- ほとんどのボードはEN312のP3およびP5ボードの要求を満たしています.
- 水分吸収 (WA) と厚さの膨張 (TS) は,ハゼルナットの木材の含有量,特に樹皮で増加しました.
- 密度プロファイルは,ハゼルの含有量が高いボードの内部構造がより均一であることを示しました.
結論:
- ハーゼルナットの木材は,特に中等レベルの置換で,構造的なパーチクルボードで松の木を部分的に置き換えることができます.
- IB強度とSWRの改善は顕著な利点です.
- ハーゼルナッツの木材の耐湿性の低下と厚さの増加を防ぐことは,ハズレナッツの木材の薄板のより広範な産業用途に不可欠です.

Wood Panel Products
120
Wood panel products are essential materials used in construction for applications such as flooring, siding, and roofing, typically available in standard dimensions of 4 feet by 8 feet, with thicknesses varying from one-quarter of an inch to one and one-eighth inches. Among the most common types of wood panels is plywood, which is produced by gluing multiple layers of thin wood veneers under pressure. The grain of the outer veneers runs lengthwise, while the grains of the interior layers run...

Introduction to Wood
321
Wood, derived from trees, is a versatile and widely used construction material. Trees feature a trunk surrounded by a protective layer of dead bark. Beneath this outer layer lies the living bark, followed by the cambium, and then the sapwood which transitions into heartwood as it matures. At the center of the trunk is the pith. The age of a tree can be discerned by examining its growth rings, which are concentric bands visible in the trunk's cross-section.

Softwoods and Hardwoods
243
Softwoods and hardwoods, derived from different types of trees, are distinguished by their leaf structures and cellular compositions, each serving unique purposes in construction and manufacturing. Softwoods come from cone-bearing trees with needle-like leaves and are predominantly composed of longitudinal cells called tracheids and a smaller proportion of radial cells known as rays. Due to their cellular structure, softwoods are commonly used in construction for structural frames, sheathing,...

Composite Masonry Walls
1.3K
Composite masonry walls combine multiple wythes of the same or different masonry materials to create a unified structure. These walls feature wythes that are bonded together either through mortar-filled collar joints, grouted spaces, or more commonly, with rigid metal ties and reinforcements, with the use of masonry header units being rare. Metal ties are preferred because they effectively minimize water penetration, as these walls primarily absorb moisture and then release it into the...

Veneer
124
Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...
