Wood has its unique advantages as a building material due to its properties:

1. Green and environmentally friendly, renewable and degradable.

2. The construction is simple and the construction period is short.

3. Warm in winter and cool in summer.

4. Excellent seismic performance.

Here are some common properties of wood:

Density: The density of wood varies depending on the species, generally between g cm.

Stability: Due to the hygroscopicity and shrinkage of wood, its stability is poor, and it is easy to deform, crack, warp, etc. due to environmental changes and signal disturbances.

Durability: The durability of wood varies from species to species, and in general, wood with a high hardness and high oil content is more durable.

Processability: Wood is easy to process, cut, and drill, but it is also prone to problems such as burrs and cracks. Collapse.

Plasticity: Wood can be plastically processed by heating, wetting, etc., such as bending, compression, etc.

Hygroscopicity: Wood has strong moisture absorption, which can regulate indoor humidity, but it is also easy to cause deformation, cracking and other problems.

The characteristics of wood have the advantages of light weight, high strength-to-weight ratio, good elasticity, impact resistance, rich and beautiful texture tone, easy processing, etc., 1. Nature: Wood is a natural material, and only it is directly taken from nature in the four main materials of steel, wood, cement and plastic commonly used by human beings, which makes wood have the characteristics of low production cost, low energy consumption, non-toxic and non-polluting.

2. Good texture: wood has good tactile properties that are easy to accept, far better than materials such as metal and glass.

3. High strength-to-weight ratio: The ratio of some strength to weight of wood is higher than that of general metals, and it is a light and high-strength material.

4. Temperature insulation: The thermal conductivity of wood is very small, compared with other materials, the thermal conductivity of aluminum is 2000 times, and the thermal conductivity of plastic is 30 times. As a result, wood has good thermal insulation properties.

5. Electrical insulation: The point conductivity of wood is poor, and it is a better electrical insulation material.

6. Machinability: The wood has a moderate degree of softness and hardness, and it is easy to process.

7. Decoration: Wood itself has a natural and beautiful pattern, and as a furniture and decoration material, it has good decoration. Due to some of the above-mentioned unique characteristics of wood.

Wood is a common raw material for construction, furniture, arts, crafts, etc., and has a wide range of uses. The characteristics of wood mainly include the following aspects:

Texture: Different types of wood have different textures, some are soft and some are hard. The texture also affects the weight and density of the wood.

Texture: The grain of each wood is different, some of the wood has a clear grain, and some of the wood has a blurred grain. The characteristics of the grain can also affect the aesthetics and performance of the wood.

Color: Different kinds of wood have different colors, some are dark in color, and some are light in color. Some woods also take on different colors in different light.

Durability: Different types of wood have different durability, some wood is easily rotten and subject to insect infestation, while others are highly durable.

Plasticity: Wood is very easy to process and deform, and can be processed into a variety of shapes and structures.

Stability: The stability of wood can be affected by factors such as humidity and temperature, and different types of wood have different adaptability to the environment.

Acoustic properties: Wood has good acoustic properties and can be used to make musical instruments and speakers.

In conclusion, different types of wood have different characteristics and uses, and choosing the right wood can improve the quality and durability of the product. At the same time, understanding the characteristics of wood also helps to properly protect and maintain wood products.

Wood has very good mechanical properties, but wood is an organic anisotropic material, and the mechanical properties of the grain direction and the horizontal grain direction are very different. The tensile and compressive strength of timber are high, but the tensile and compressive strength of the sgrain are low.

Timber strength also varies from tree species to tree species and is affected by factors such as timber defects, load action time, moisture content and temperature, among which wood defects and load action time are the most affected. Due to the different size and position of the knots, and the different force properties (tension or compression), the strength of knotted wood can be reduced by 30 to 60% compared with knotless wood. The long-term strength of the timber is almost half of the instantaneous strength under long-term load.

Lightweight: Compared to other building materials such as steel and concrete, wood is a lightweight and less dense material.

High strength: Although the wood is relatively light, it is superior in strength. Dense hardwoods, such as nutwood, are more resistant to compression than thin pine.

Good toughness: In addition to high strength, wood also has good toughness, that is to say, it can withstand the action of external forces and is not easy to break.

Durability: With proper treatment, wood can be used for a long time and is more resilient to climate change. Although it has a certain decaying effect, it can be effectively antiseptic after treatment.

Easy to process: Wood is easy to process and engrave compared to metal materials, and can be made in any imaginable shape and size. This makes it a very flexible material that can be used in a wide range of indoor and outdoor buildings.

Aesthetics: Wood is very decorative, and its natural properties make it ideal for creating a soft, comfortable home atmosphere and design.

Renewable: Wood is a renewable material that can be produced sustainably through afforestation and reduce the negative impact on the environment.

Rich grain: Each piece of wood has a unique grain and color, making it suitable for interior decoration as well as for furniture and crafts.

Thermal insulation: Wood is able to perform well in terms of thermal insulation and heat storage, which makes it a more environmentally friendly choice.

Health and environmental protection: Wood is a healthy and environmentally friendly material, there is no radioactive pollution, and it emits a small amount of carbon dioxide in the production process, which has environmental advantages compared with other materials.
