What are the basic characteristics of wood
The characteristics of wood have the advantages of light weight, high strength-to-weight ratio, good elasticity, impact resistance, rich and beautiful texture and color, and easy processing.
1. Naturalness: Wood is a natural material. Among the four main materials commonly used by mankind, steel, wood, cement, and plastic, only it is directly derived from nature. Therefore, wood has low production cost, low energy consumption, non-toxicity, and No pollution and other features.
2. Good texture: wood has good tactile characteristics that are easily accepted, far superior to materials such as metal and glass. 3. High strength-to-weight ratio: The ratio of certain strength to weight of wood is higher than that of general metals, and it is a light and high-strength material.
4. Thermal insulation: The thermal conductivity of wood is very small. Compared with other materials, the thermal conductivity of aluminum is 2000 times that of it, and the thermal conductivity of plastic is 30 times that of it. Therefore, wood has good thermal insulation properties.
5. Electrical insulation: wood has poor point conductivity and is a good electrical insulation material.
6. Processability: The wood has moderate hardness and is easy to process.
7. Decorative: Wood itself has natural and beautiful patterns. As furniture and decorative materials, it has good decorative properties. Due to some of the unique characteristics of wood.
8. In construction applications, wood is more resistant to fire than steel (contrary to the common sense of many people): After a large fire, many ancient wooden buildings are only charred on the outside, but they still stand tall, and the strength of the internal structure is still high; on the contrary; However, after many reinforced concrete buildings were fired, the steel bars were burnt, causing the buildings to collapse and the buildings were severely damaged.
9. Except for some high-density special woods, most woods have a lower specific gravity than water and can float on the water and can be used to make ships.
10. The shortcomings of wood are flammable, perishable, intolerant of insects, shrinkage and damp swelling.
11. It is one of the most widely used materials. Wood can be made into boards, furniture, plywood and other products and used as raw materials for papermaking and chemical fiber industries.
