Advantages and disadvantages of green oka wood handle, advantages and disadvantages of green oka woo

After the green oka wood is dry, it is as hard as gold steel, if it is used to make the floor, it is absolutely resistant to the grinding of the rock, if it is used to make a hammer, it is not only durable but also has no ** force.

Type: Hardwood.

Appearance: Known as the "Queen of the Forest", the tree is tall and beautiful, and it is one of the famous timber tree species in Europe. The height of the tree can generally reach 30m, sometimes it can reach 45-50m, and the diameter is above.

The height under the branches is generally 9-l5m, and it can reach more than l8m in dense forests. It has a shorter lifespan of up to 250 years. The leaves are golden and reddish-brown in autumn, and the dead leaves do not fall in winter, so young trees are often used as hedgerows in gardens and other fields.

The distinction between the edges of the heartwood is not obvious or slightly clear. The color of the freshly harvested wood heartwood is white to light brown, and the color becomes darker when placed in the air, and it is light turquoise reddish-brown. Logs grown in cold regions of northern Europe, such as Denmark and Northern Europe, often have dark hearts, called red heartwood, and often have dark stripes.

The most common measure in South-Eastern European countries is to steam the heartwood immediately after it is cut down to change its color to a fixed purple or bright red. The wood grain is straight, and the longitudinal section has wide wood rays. The string saw board is quite smooth, while the diameter saw board has an attractive silver pattern.

The timber structure is delicate and uniform. The wood is heavy, hard, and has no smell or taste.

Aoka wood is a common type of wood that has the following advantages and disadvantages:

Advantages: 1. High mechanical strength: The mechanical strength of Qinggang wood is high, and it has good mechanical properties of bending, tensile resistance, compression resistance and shear resistance, so Qinggang wood is widely used in making various wood products and tools.

2. Good rot resistance: Qinggang wood has good rot resistance, is not easy to be affected by fungi and insect pests, and can remain stable for a long time.

3. Good processing performance: Qinggang wood has good processing performance, easy to cut, grind, nail and other operations, and is not easy to crack and deform.

4. Beautiful texture: The texture of Qinggang wood is beautiful, the texture is staggered, clear and natural, and it has a good decorative effect.

5. Environmental protection: Qinggang wood is a natural renewable resource, and its use has little impact on the environment and has good environmental protection.

Disadvantages: 1. Easy to crack: The wood nature of Qinggang wood is relatively dry and the water content is low, which can easily lead to wood cracking.

2. High hardness: The hardness of Qinggang wood is higher, so it is difficult to process and wear out quickly to tools.

3. Large texture changes: the texture of Qinggang wood changes greatly, and the texture of Qinggang wood in different parts and different ages of canopys varies greatly, so it is relatively unstable.

4. Poor dyeability: The dyeability of Qinggang wood is poor, and it is difficult to dye it into dark or bright colors.

5. Flammability: Qinggang wood is a flammable wood, and it is necessary to pay attention to fire safety. The chain is <>

Name: European Beech or European Beech The scientific name of the puller is Fagus Sylvatica, also known as the English mountain.

English beech, French beech, Danish beech, Romanian beech, Carpathian beech, etc., belong to the genus Fagus in the family Douaceae. This tree species is a family of tree species with the domestic rice heart tree (fagus engleriana) (mainly distributed in Zhejiang, Anhui, Sichuan, Hubei, Shaanxi and other places) and fagus longipetiolata (mainly distributed in Zhejiang, Anwei, Jiangxi, Yunnan, Guizhou, Hunan, Hubei, Sichuan and other places). After the green oka wood is dry, it is as hard as gold steel, if it is used to make flooring, it is absolutely wear-resistant, if it is used to make a hammer, it is not only durable but also has no ** force The real beech wood produced in China is the wood of the genus Elm (Zelkova), and the main tree species are; Beech (Zelkova schneidriana), also known as "blood beech", "yellow beech", "red beech", etc.; Large-fruited beech (Zelkova serrata), also known as "Taiwan beech", "zelkova serrata" and so on.

Beech wood is mainly distributed in the vast area south of the Yellow River Basin, and is an excellent timber for the textile, shipbuilding and furniture industries, and its structure and cutting properties are different from those of the European water green grass. At present, it is being discussed to formulate the standard name of the well that will be submitted for review (Chinese imported timber name standard), and the European water green hole will be used as the standard name.

Timber cut-off boards have an aesthetically pleasing pattern and a wide longitudinal section and are particularly suitable for the production of decorative planed thin timbers and decorative decks. It also makes building materials, furniture, flooring, marine materials, musical instruments, plywood, children's toys, sporting goods, tool handles, etc.
