Oak is a paralyzed genus, belonging to the family Beech, the heart of the tree is yellowish brown to reddish brown, the growth wheel is obvious, slightly wavy, heavy and hard. Mainly produced in Europe and North America, currently produced in large quantities from Russia and the United States.
In China, Jilin, Liaoning, Shaanxi, Hubei and other places are distributed with eucalyptus, which is similar to oak, with similar texture. In English, it is generally called oak with oak. China's Jilin and Liaoning have had large productions. Hubei Shennongjia and Shaanxi also have a small amount of eucalyptus production. However, the domestic production of sorghum timber is relatively short, and domestic production is not formed. It is not an ideal furniture material. At present, resources are limited, and due to forest protection measures, China has produced very little.
Domestically produced eucalyptus quality materials are rare, and superior oak still needs to be imported from abroad. The excellent materials cost nearly 10,000 yuan per cubic meter, which is also an important reason for the high price of oak furniture.
Characteristics of oak furniture:
advantage:
1) It has a distinctive mountain-shaped wood grain, and the touch surface has a good texture;
2) The texture is firm, the finished product has a firm structure and long service life;
2) High grade, suitable for making European furniture
Disadvantages:
1) There are relatively few high-quality tree species. Most of them are imported from Russia and the United States, and some are imported from Turkey, Austria, Germany and Canada. There are many other regions in Europe and America, but the import volume is very small;
2) Usually imported oak sheets have been subjected to strict drying treatment abroad and have good stability. Some manufacturers directly import logs from abroad and cut them by themselves. At present, many oak furniture manufacturers in China have high stability in oak furniture. However, due to the hard texture of the oak, it is more difficult to remove the water. The furniture made from the clean water may begin to deform or shrink and crack after a year and a half.
3) The phenomenon of replacing oak with rubber wood in the market is widespread. If the customer's professional knowledge is insufficient, it directly affects the interests of consumers.
The scientific name of oak (also known as eucalyptus) in wood science is QUERCUS SPP (Latin meaning "excellent tree species"), widely distributed in the vast area of ​​the northern hemisphere, with more than 300 varieties, oak belongs to the family Fagaceae, genus The oak in the market is roughly divided into two categories: red oak and white oak. However, the red oak is not red and the white oak is not white. The color distinction is not very obvious. The key point is the difference between the tube hole and the forest ray in wood science. For example, there are immersed bodies in the pores of white oak. This feature makes white oak widely used in wine barrels for storing wine. It is a world-famous oak casks, and blush oak cannot be used as barrels.
Oak is widely used in decorative materials and furniture, in its excellent material properties: oak hard and hard texture straight, thick structure, light color and elegant texture, high mechanical strength, wear resistance, but wood is not easy to dry sawing and cutting. A large number of oak is used in decorative materials, furniture materials, sports equipment, shipbuilding materials, vehicle materials, flooring materials, and the like. The slice of white oak and red oak is also the ideal material for the production of laminated plywood. The pattern also has the difference between straight and horizontal stripes. The straight lines are more beautiful and the price is slightly more expensive.
Because the United States imported red oak (OAK, RED) and white oak (OAK, WHITE) are in high capacity, high of 10,000 yuan / cubic meter, causing speculation in some operators, there have been rubber wood in the market Known as the oak, the rubber-wood sofa is called the oak sofa, and the result is compensated by the consumer to the court. The rubber wood is a genus of the rubber tree, which is made of rubber. It is made of rubber, but its material is poor. However, after a certain chemical treatment, the wood is hardened and can also be used for furniture, but after all, the oak is wind, horse, and cow. Two varieties in common, and not at all in a grade.
