OSB板材（定向结构刨花板）相较于胶合板、密度板、实木颗粒板等，核心特性可总结为以下十点：

Compared with plywood, density board, particleboard and other wood-based panels, the core characteristics of OSB (Oriented Strand Board) can be summarized into the following ten points:

1.  超高结构强度：木质刨片按纵向、横向交错分层压制，形成类似“胶合板”的力学结构，抗弯曲、抗剪切能力远超实木颗粒板，可直接作为承重基材。

Ultra-high structural strength :Wood strands are pressed in cross-oriented layers , forming a mechanical structure similar to that of plywood. Its bending and shear resistance far exceeds that of particleboard, allowing it to be directly used as a load-bearing base material.

2.  优异防潮性：采用MDI防水树脂胶黏剂，防潮性能优于普通密度板和实木颗粒板，在潮湿环境（如厨房、卫生间干区）使用不易变形。

Excellent moisture resistance: It adopts MDI waterproof resin adhesive, so its moisture resistance is better than that of ordinary density board and particleboard. It is not prone to deformation when used in humid environments (such as the dry areas of kitchens and bathrooms).

3.  尺寸稳定性强：交错层压结构抵消了木材单向收缩的特性，温湿度变化时膨胀收缩率低，远优于实木和普通刨花板，不易开裂翘曲。

Strong dimensional stability: The cross-laminated structure offsets the unidirectional shrinkage characteristic of wood. It has a low expansion and shrinkage rate when temperature and humidity change, which is far superior to solid wood and ordinary particleboard, and is not easy to crack or warp.

4.  握钉力出色：内部刨片颗粒大、结合紧密，无论是钉入还是拧入螺丝，都能提供持久稳固的握力，且多次拆装后握钉力衰减小。

Outstanding screw-holding capacity: The internal wood strands are large in size and tightly bonded. Whether nailing or screwing, it can provide long-lasting and stable holding force, with little loss of screw-holding capacity after multiple installations and disassembly.

5.  环保性可控：优质OSB板使用MDI胶（无甲醛释放）或低醛胶，符合Enf级环保标准。

Controllable environmental friendliness: High-quality OSB uses MDI adhesive (formaldehyde-free emission) or low-formaldehyde adhesive, complying with the ENF-grade environmental protection standard.

6.  性价比高：同等结构强度下，OSB板的价格低于多层胶合板；同等价格下，性能又优于实木颗粒板，是成本与性能平衡的优选。

High cost performance: At the same structural strength level, the price of OSB is lower than that of multi-layer plywood; at the same price level, its performance is better than that of particleboard. It is an optimal choice that balances cost and performance.

7.  纹理独特有辨识度：表面保留木质刨片的原始纹理，呈现粗犷自然的工业风，可直接做饰面（需上清漆），无需额外贴皮，减少加工步骤。

Unique and recognizable texture: The surface retains the original texture of wood strands, presenting a rugged and natural industrial style. It can be directly used as a decorative surface (with a clear varnish finish required), eliminating the need for additional veneering and reducing processing steps.

8.  加工性能良好：可锯、可刨、可钻，切割后边缘不易崩边，能适配多种五金件，方便定制家具、柜体等。

Good processability: It can be sawn, planed and drilled, with no edge chipping easily after cutting. It is compatible with various hardware fittings, facilitating the customization of furniture, cabinets and other products.

9.  隔音效果较好：内部多孔结构和厚重材质能有效吸收声波，隔音性能优于轻薄的密度板和单层实木板，适合做室内隔断、地板基材。

Favorable sound insulation effect: Its internal porous structure and heavy material can effectively absorb sound waves. Its sound insulation performance is better than that of lightweight density board and single-layer solid wood board, making it suitable for indoor partitions and floor base materials.

10. 材料利用率高：由小径木、速生材的刨片制成，无需依赖大径实木，符合环保可持续理念，原材料供应稳定，价格波动小。

High material utilization rate: It is made of wood strands from small-diameter logs and fast-growing timber, without relying on large-diameter solid wood. It conforms to the concept of environmental protection and sustainability, with stable raw material supply and small price fluctuations.
