概括
子木具有碎片板生产的潜力,部分取代了松树. 虽然它增强了内部粘合强度和螺丝拉伸强度,但较高的含量会降低曲强度,增加厚度膨胀,因此需要提高耐湿性.
科学领域:
- 材料科学
- 木材科学
- 可持续的材料
背景情况:
- 碎片板是广泛使用的结构材料.
- 松树 (Pinus sylvestris L.) 是一个常见的原料.
- 探索子 (Corylus avellana L.) 等替代性木材来源对于可持续性和资源多样化至关重要.
研究的目的:
- 调查使用子木作为单层结构板生产中的松树的部分或全部替代品的可行性.
- 评估使用不同子木材制造的碎片板的机械和物理性能.
- 根据欧洲标准,评估子木板的适用性.
主要方法:
- 碎片板使用0%,5%,10%,25%,50%和100%的子木替代品制造.
- 使用甲 (PF) 树脂的板的目标密度为700公斤米3,厚度为13毫米.
- 根据欧洲标准进行了机械测试 (MOR,MOE,IB,SWR) 和物理测试 (WA,TS).
- 分析了它们的密度.
主要成果:
- 增加子木材含量降低了曲强度 (MOR) 和硬度 (MOE),但提高了内部结合强度 (IB) 和螺丝拉伸强度 (SWR).
- 大多数板材符合P3和P5板材的EN312要求.
- 随着子木材含量增加,尤其是树皮,吸水率 (WA) 和厚度膨胀 (TS) 增加.
- 密度概况显示,含量较高的木板内部结构更为均.
结论:
- 子木在结构板中可以作为可行的部分替代品,特别是在适度的替代水平下.
- 改善IB强度和SWR是显著的好处.
- 为了更广泛的工业应用子木片板,应对降低的耐湿性和增加的厚度膨胀是必不可少的.

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...
