软木与硬木胶合板：主要差异解释

一种称为胶合板的材料是通过将薄“层”或多层木单板粘合在一起，同时将相邻层的木纹旋转最多 90 度而制成的。 It belongs to the family of produced boards, which also includes particleboard, oriented strand board, and medium-density fiberboard (MDF) (chipboard).

胶合板的两种常见类型是软木胶合板和硬木胶合板。木质装饰和家具材料包括胶合板。它由厚度均匀或厚度不同的木板组成，并用不同强度的胶水连接。胶合板有两种类型：硬胶合板和软胶合板。

胶合板的硬度或柔软度取决于木材的质量。 Hard plywood is utilized in applications where it must withstand extreme pressure, while soft plywood is suitable for the majority of other industrial and construction uses.

那么，在本文中，我们将探讨什么是软木胶合板和硬木胶合板、它们的区别以及它们的应用。

让我们开始吧！

什么是软木胶合板？

软木 由于胶合板由云杉、松木和冷杉制成，有时也被称为云杉-松木-冷杉或 SPF。虽然雪松 (Cedrus sp.) 和花旗松 (Pseudotsuga menziesii) 都可以用来制作它。

When constructed from spruce (Picea sp.), the noticeable grains are covered by a technique to make the plywood more effective and as hard as concrete when used for building and shuttering strands.

最典型的尺寸为 1.2 x 2.4 米（3 英尺 11 英寸 7 英尺 10 英寸），或稍大的英制尺寸 4 英尺 8 英尺。层厚度范围为 1.4 毫米至 4.3 毫米。 The thickness and grade of the sheet determine the plies, which are always odd.

较薄的 16 毫米（5/8 英寸厚）胶合板可用于屋顶。根据地板托梁之间的间距，底层地板的厚度必须至少为 19 毫米（3/4 英寸）。

榫槽 (T&G) 胶合板经常用于地板应用。 When the joints do not lie across joists, this prevents one board from moving up or down about its neighbor, creating a solid-feeling floor. T&G plywood is typically found in thicknesses between 13 and 25 millimeters (1/2 and 1 in).

应用程序

高质量、高强度板材的许多用途都需要使用胶合板。从这个意义上说，质量是指抗翘曲、扭曲、收缩、开裂和断裂的能力。 Exterior bonded plywood is appropriate for use outside;然而，由于水分会影响木材的强度，因此当水分含量保持在相对较低的范围内时，性能最佳。

The dimensions and strength characteristics of plywood are unaffected by sub-zero temperatures, allowing for certain unique applications. Well, the following are the applications of softwood plywood:

1. For the ventilation panel.
2. For flooring, walls, and roofs for building construction.
3. 用于机械、车辆零部件制造。
4. 用于建筑工程。
5. 在工业领域。
6. 用于包装。
7. For making a fence around an area.

What is Hardwood Plywood?

Hardwood Angiosperms are used to make plywood. This kind of plywood can be recognized by its hardness, surface hardness, inflexibility, and resistant qualities.使用此可以支撑较重的重量。

软木胶合板通常用于建筑和工业用途，通常由雪松、花旗松、云杉、松木和冷杉（统称为云杉-松木-冷杉或 SPF）制成。 For demanding end usage, hardwood plywood manufactured from wood from dicot trees (oak, beech, and mahogany) is utilised.

Excellent strength, stiffness, durability, and creep resistance are the hallmarks of hardwood plywood. It excels at heavy-duty floor and wall structures thanks to its strong planar shear strength and impact resistance. Construction made of orientated plywood provides a large wheel carrying capacity. Excellent surface hardness, wear- and damage resistance can be found in hardwood plywood.

应用程序

Common applications of hardwood plywood include:

• Panels in concrete formwork systems
• Floors, walls, and roofs in transport vehicles
• Container floors
• Floors subjected to heavy wear in various buildings and factories
• Scaffolding materials
• 桦木胶合板在独特的应用中用作结构部件，例如风车叶片和液化天然气 (LNG) 运输船的隔热箱

The following are other applications of birch plywood:

• High-end loudspeakers
• Die-cutting boards
• Supporting structure for parquet
• Playground equipment
• 家具
• Signs and fences for demanding outdoor advertising
• Musical instruments
• Sports equipment

Difference Between Hardwood Plywood and Hardwood Plywood

We’ll look at the difference between hardwood plywood and softwood plywood in the following aspect:

• Differences in wood
• The difference in physical attributes
• Difference in usage
• Difference in limitations

Differences in Wood

The type of wood used to create plywood is the main difference between hard and soft plywood.云杉、花旗松和枫树因其柔韧性和延展性而成为软质胶合板的理想树种。

桦木或红枫、桃花心木等热带树木以其强度、抗压性和刚度而闻名，是硬质胶合板的最佳选择。

The Difference in Physical Attributes

Three, five, and seven plies of soft plywood are available. The ply refers to the number of sheets that are adhered together to form a single board.每层厚度可以在 0.1 到 0.6 英寸之间，具体取决于成品面板所需的厚度。

There are also three-, five-, and seven-ply options for hard plywood.由于涂有额外的密封剂，它更耐碎裂、弯曲和腐烂。

Difference in Usage

在低磨损和暴露于气候的区域，使用软胶合板。 It is utilised in DIY projects because of its flexibility, particularly when the plywood may be switched out on a regular basis.它经常用于地板、台面、房产周围的围栏、轻到中重量的材料容器以及橱柜的外部。

Hard plywood is more expensive and is offered at a premium because of its durability and longer life.这种胶合板用于需要专家协助的任务以及木材容易变质的环境。 Hard plywood is typically used for things like the floors of containers that transport heavy loads, particularly over long distances.

It is also used for scaffolding and other construction materials; heavily trafficked floors in places like factories and offices;涡轮叶片； insulation boxes for fuel carriers; different playground equipment; and some types of furniture.

Difference in Limitations

因为它容易获得且灵活，DIY 爱好者喜欢软胶合板。但由于是软木材质，表面容易出现裂纹，弯曲速度快，而且防潮能力不是特别强。

如果使用研磨性清洁产品，表面可能会变得暗淡和损坏，从而需要反复更换。但由于用于制造胶合板的木材有多种选择，客户可以选择最适合自己要求的一种。

软胶合板有困难，但硬胶合板更耐用且不易出现问题。 There are, however, fewer options and a higher price.薄木饰面更容易破裂，增加维护费用。
