- 评估再循环塑料的纳入对碎片板的物理,机械和挥发性有机化合物 (VOC) 排放性能的影响.
- 确定回收汽车塑料填充剂的最佳类型 (油漆或未油漆的保险,燃料) 用于碎片板生产.
主要方法:
- 三层颗粒板是使用传统的热压技术制造的,使用10%的回收汽车塑料填充剂.
- 包括吸水 (WA) 和厚度膨胀 (TS) 在内的物理性能根据适用的标准进行测量.
- 评估了机械性能,例如内部粘合强度 (IB),破裂模量 (MOR),弹性模量 (MOE) 和螺丝驱动扭矩 (SDT).
- 分析了挥发性有机化合物 (VOC) 排放量,以确定复合材料对环境的影响.
主要成果:
- 颗粒板的密度在0.70至0.72g·cm-3之间,与参考颗粒板 (0.72g·cm-3) 相比.
- 吸水率 (WA) 和厚度膨胀率 (TS) 的结果各不相同,一些塑料填充板显示的值略低于或与参考值相当.
- 使用塑料填充剂,机械性能,特别是内部粘合强度 (IB) 略有降低,未涂料的填充剂比涂料的填充剂产生更好的结果.
- 加入10%的回收塑料并没有增加总体的VOC排放量;事实上,与仅用木质的碎片板相比,它导致了总体VOC的减少.

Wood Panel Products
70
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...

Structural Properties and Dimensions of Lumber
80
Wood's structural properties derive from fibers aligned along the tree's length, contributing significantly to its mechanical strength. Wood exhibits up to twenty times greater tensile strength along these fibers compared to across them, and generally shows better performance under compression than tension. The length of fibers varies, with hardwoods having fibers around one twenty-fifth inch long and softwoods ranging from one-eighth to one-third inch.

Introduction to Wood
210
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
149
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,...

Lumber
108
Lumber is derived from logs which are harvested, debarked, and processed into long pieces with a rectangular cross-section. The transformation of logs into lumber involves multiple steps, beginning with an automated saw that slices the log into slabs. These slabs are then transported via a conveyor belt to smaller saws, where they are cut into square-edged pieces of specific widths.
Initially, the surfaces of these lumber pieces are rough, and their dimensions may vary slightly from one end to...
