Recently, there have been many incidents of counterfeit oak furniture on the market, which has made the furniture purchased by consumers inconsistent with the actual needs. Many merchants use the consumers to understand the prediction fraud, and there are five major misunderstandings in the identification of rubber wood.
The first misunderstanding, oak is the abbreviation of rubber wood.
Oak is a parasitic genus, belonging to the family of beech, the heart of the tree is yellow-brown to reddish brown, the growth wheel is obvious, slightly wavy, with a distinctive mountain-shaped wood grain, heavy and hard, from north China to Jilin, Liaoning to Hainan, Yunnan There are distributions, but quality materials are rare, and superior oak still needs to be imported from abroad. Rubber wood is abundant in Southeast Asian countries. It is produced in Yunnan, Hainan and coastal areas. It is the backbone of rubber trees and a source of raw materials for latex. The rubber wood color is light yellow-brown, the annual ring is obvious, the wheel boundary is dark band, the pipe hole is very small; the wooden structure is thick and uniform; the texture is oblique, the wood is hard, and it is recognized as the most widely used lightweight hardwood solid wood in the world. one. So whether it is domestic wood or imported wood, oak = rubber wood is wrong.
The second misunderstanding, rubber wood is toxic, furniture made of rubber wood is easy to cause skin allergies.
Natural rubber (that is, rubber latex is prepared by consolidation, washing, molding, and drying), its main component is polyisoprene, the content is above 90%, in addition to a small amount of protein, fat and acid, sugar and Ash. Natural rubber is widely used in the fields of medicine and health and daily life, such as blood vessels and baby pacifiers. From these products closely related to human health, we can see that the rubber juice does not cause damage to human health after being treated, and the rubber wood is basically free of chemical components after being processed.
The third misunderstanding, rubber wood contains many sugars and is difficult to remove, easy to change color, decay and insects, and is not easy to dry, not wearable.
In the past, due to the particularity of rubber trees, the rubber wood that was harvested quickly became discolored, moldy and rotted. However, with the advancement of the furniture manufacturing process, the rubber wood used to make the furniture has solved the above problems, and effectively retains and highlights the excellent characteristics of the rubber wood.
In the fourth misunderstanding, rubber wood is cheap and the cost of making furniture is low. Imported red oak is 6-8 times that of rubber wood.
At present, the price of domestic rubber wood is 2,500 to 3,000 yuan / cubic, and the price of imported rubber and wood in Thailand and Malaysia is around 3,500 yuan / cubic, and some even reach 6,000 yuan / cubic. The price of oak is 4,500-8,000 yuan / cubic. The oak furniture we generally refer to is the imported red (white) oak. The so-called domestic oak is actually the northeastern eucalyptus or eucalyptus, because it is imported with the oak. Domestic sellers collectively refer to them as oak, whose performance, texture, texture and quality are comparable to real oak (imported oak), and the price is much lower.
In the fifth misunderstanding, rubber wood hardness, material, texture and performance are poor.
Rubber wood, like other wood materials, is called lignocellulosic material. Compared with the famous precious woods such as green nan, citron, huangboluo, 椴森, 柳桉, and lamming, the physical and mechanical properties are not inferior, and the oaks with similar colors and textures are similar. The air dry density of domestic rubber wood is 0.61kg/cm3, the imported rubber wood can reach 0.65kg/cm3, and the air dry density of oak is 0.66~0.77kg/cm3. Both of them belong to deciduous wood (ie hardwood), rubber wood end hardness For 5492N, the hardness of the oak end face is 6510 ~ 10000N, the flexural strength of the rubber wood is 91.8MPa, and the bending strength of the oak is 88.1 ~ 118 MPa. From these important performance data, the density of rubber wood is not much lower than that of oak, but the difference is very small.
When buying oak furniture, you should find out the origin, the amount of solid wood, etc., so as not to be deceived.
