The name of the wood on the market is very confusing. The names of wood and wood products are very irregular. Some manufacturers take the format of the wood name seriously, but confuse the foreign name with the Latin name and misinterpret the foreign name. The Chinese name of the specification. Some manufacturers only use the self-contained non-standard Chinese name; even worse, the competition ignores the specification of the wood name, and the plain text tells the consumer: "The name of the floor sold by the company is the name or common name of the product", and the climbing of the redwood species Phenomenon, the name of the wood that climbs the red sandalwood is 38, and there are many red sandalwood, jade sandalwood, iron sandalwood, golden sandalwood, fragrant sandalwood, dragon sandalwood, ancient sandalwood, teak sandalwood, etc. For example, Guibaurtia sp., which is mainly produced in Africa, is called Brazilian rosewood; some two woods of the same name are not the same tree species. For example, the floor tile red sandalwood refers to the Mauilkara sp. The furniture manufacturer refers to the Swiss bean (Swartizia sp.) as red sandalwood, and the domestically known southwestern birch (Belula alnoides) is called cherry wood (Prunus sp.), rubber wood (Heuea brasikiensis) and eucalyptus (Quercusmogolica). It is called oak, and Fagus syluatica is called eucalyptus (made in China. It is Zelkova. There is no standard Chinese name, there is no standard, no standard, no one can distinguish its authenticity and excellent. inferior.

5.8 Chicken wing wood essential conditions

The names of wood products are different, the tree species are different, and the material properties, quality and price are also different. In the fake mahogany, in addition to the above-mentioned ancient eucalyptus, there are also Swartizia sp., Dialum sp., Afzella sp., Pericopsis sp., and gum. Tree species such as Glutahe sp and Melanorrhoea sp.
Another important issue is the distinction between rosewood and Asian rosewood . In the four regulations, they have two identical; the difference is that the former has a fine and fine wood structure, and the average pipe diameter is not more than 200um and the wood contains water. At a rate of 12%, the air-dry density is greater than 0.76 g/cm3, which is in mahogany, while the latter does not belong to mahogany.
This difference is easy to distinguish when comparing with wood samples, but it is difficult to distinguish after making products. When consumers purchase mahogany products, they must require the manufacturer's contract to write the type of mahogany according to the national standard of "Redwood". At the same time, it must be stated whether the whole material is mahogany or the main component is mahogany. In order to reduce the damage to wood products, the excipients are often taken out to make slices. Otherwise, once there is a dispute, there is no strong basis.
