What is Oak (red oak, white oak)
oak, also known as Oak, is widely distributed in vast areas of the Northern Hemisphere, with more than 300 varieties. Oak belongs to the genus Fagaceae and Quercus. Oak in the market is roughly divided into two categories: Red Oak and White Oak, but red oak is not red, white Oak is not white, and its color distinction is not very obvious. The key point of distinction lies in the difference between pipe holes and forest rays in wood science. For example, white oak pipe holes have immersion filling bodies, this feature makes White Oak widely used in wine barrels for wine storage abroad. It is a world-famous material for oak barrels, while red oak cannot be used as barrels. Oak is heavy, hard, straight in texture, thick in structure, elegant in color, beautiful in texture, quite high in mechanical strength, abrasion resistance, and Wood is not easy to dry, saw and cut.
Oak is produced in Europe, with long growth period, high density, hard material, relatively distinctive mountain-shaped wood grain, and good texture on the touch surface, occupying a certain proportion in the furniture industry, real Oak is more expensive. Superior oak still needs to be imported from abroad, and the excellent materials reach nearly 10,000 yuan per cube, which is also an important reason for the high price of oak furniture.
Oak is divided into domestic and imported types. Red Oak and white oak imported from the United States are expensive, with a height of tens of thousands yuan/cubic meter, like processed square materials, the market price of 1-inch thickness is about 6000 or 7000 yuan per cubic meter, and the price of 2-inch thickness is more than 9000 yuan per cubic meter. Of course, Oak is distributed in China from north to Jilin, Liaoning, south to Hainan and Yunnan, but high quality materials are rare, and superior oak still needs to be imported from abroad. At present, the price of domestic Oak sold on the market is much lower than that of imported oak, which is generally mainly produced in Yunnan and Hainan, while Yunnan Oak is better than Hainan oak and Yunnan Oak (square material) the market price is 6000~10000 yuan/cubic meter. Oak on the market now includes European white oak, Indonesian Oak, classical Oak, Indonesian rain Oak, Royal Oak and red oak.
What is rubber wood?
The raw material of rubber wood is rubber tree that produces natural rubber. After rich phase, it is cut off to make finger board, so the regular name is: rubber wood finger board or rubber wood glulam. Rubber Wood also has wooden squares or large boards, but it is not common. It is irresponsible to describe rubber wood as oak, which is a careless behavior. Oak is a high-grade material, and there is no finger board, which cannot be compared with rubber wood at all.
Rubber wood is now widely used in furniture manufacturing, and its advantages are as follows:
1. Rubber wood solid wood has good texture, beautiful texture and uniform texture.
2. Rubber wood has strong plasticity in the process of making furniture, good processing performance, easy to create and easy to drill, so it is suitable for making products with beautiful shapes and soft curves.
3. It is light and easy to wear. It can accept all types of color dyeing and paint. It is easy to match with the color tone of other kinds of wood, and the paint coating performance is good.
4. The cut surface is smooth and easy to glue.
5. It is not easy to crack in dry areas in the north.
6. Damp is not easy to deform.
7. Good hardness, natural high strength and low grinding performance, especially suitable for stairs, floors, tables, countertops, solid wood door, etc.
Therefore, many furniture panels are made of rubber wood finger board, which is also an excellent material for woodworking DIY. Glued laminated timber belongs to the mass industrialized production of solid wood panels spliced small board, with typical WWW serrated interfaces. Similar to fir wedge joint board, it is a common material. Market price standard plate (122cm × 244cm, thickness between 6mm and 50mm). The price is about 300 yuan per piece, that is, about 100 yuan per square meter.
Is rubber wood poisonous?
Why is rubber wood corrupted to be poisonous? The reason is that rubber wood itself contains high sugar content and is prone to insects. Therefore, before making furniture materials, chemical treatment is required, that is, spraying with chemical liquid medicine, in order to neutralize sugar, I don't know the specific principle. In short, it damages the environment of high sugar and avoids insects. The wood after chemical treatment is qualified rubber wood, and then enters the market through drying and other procedures.
As for the concept of toxic or not, chemistry is not equal to toxic. Paint is the most typical chemical substance, but solid wood furniture will have paint. There are many solid wood cabinets made of rubber wood finger board, which are basically exported. I believe that quarantine and safety measures in developed countries are better than those in China. If rubber wood is poisonous, it is impossible to export in large quantities.
Rubber wood is also divided into domestic and imported categories. The price of domestic rubber wood Square is about 3,000 yuan/cubic meter, and the price of imported rubber wood Square is about 6,000 yuan/cubic meter.
Identification of oak and rubber wood
just because rubber wood and oak are not the same grade of wood, it is a misleading behavior for consumers to call "rubber wood" referred to as "oak" in the market. So, how can ordinary consumers be identified?
1. Basically, there are relatively few high-quality tree species in oak furniture. If imported, the price is relatively high.
2. Pay attention to whether the wood grain is clear and beautiful. Because it has relatively distinct mountain-shaped wood grain, the clearer the oak wood grain is, the higher the value is. While rubber wood has no oak-specific wood grain.
3. Pay special attention to whether the wood is fine and clean. If consumers buy dark oak furniture, they should carefully check whether there are painted parts and whether there is any unique fine and clean oak.
4. Also, see if the wood color is pure. Oak Furniture is best to choose the original color type, while rubber wood is not pure in color, even with miscellaneous spots and black spots.
Consumers should pay special attention to those with deep coloring (such as dark red, dark black, etc.) and marked as oak furniture. At present, some furniture manufacturers in China buy a kind of extremely cheap Miscellaneous wood from Hunan, Jiangxi and other places to pretend to be oak. This kind of miscellaneous wood is firm but not tough, and will crack for a long time.
It is worth mentioning that, due to the hard and heavy oak texture, it is difficult to remove water. Furniture made without removing water began to deform after a year and a half, so consumers should be especially careful when buying. Oak material is found to be a good material in use, and the price is relatively moderate.
