Nowadays, the international timber trade and white wood sold in the market should be divided into white wood and imitation white wood.
White wood refers to the title of a class of commercial timber species such as: "China White Wood" commercial material name Zi Yan T. Amuremsis Rupy check "Chinese wood" P674; "Southeast Asian white wood" commercial material name Prismatic wood Gonystylus banranus check "Southeast Asian wood" P96; "African white wood" commercial material name Sycamore Tiplochiton Scleroxylon K·Schum, check "new wood professional technology Manual "P441; "American White Wood" commercial material name American Liriodendron check "Wood Science and Technology Dictionary" P568, said the American white wood refers to the sapwood of the American Liriodendron, English name White Wood, scientific name l iriodemdrontulipiferal, check the "main world" Introduction to Timber Species, P269, Note: This species of wood, also known as White Wood, should not be confused with the trade name of coniferous European red pine wood. In the United States, there is also a lizard called poplar (Wilwood PoPlay). See "Foreign Commercial Tree Species Name" Pll3, should not be confused.
The so-called white wood should have the following four conditions:
1. Wood color should have logs or plates of natural pure white or light yellowish white wood (such as sapwood of Liriodendron chinense processed into sheet);
Second, the material generally has a straight texture, fine structure, slightly soft to medium hard, light to medium density, good processing properties, sawing, rotary cutting, drilling, smooth polishing, easy to engrave. The disadvantage of no nail cracking, easy to bend, dry generally does not crack, deformation, good dimensional stability, bonding, good paint coloring performance.
Third, mainly applicable to lines, decorative strips (boards), Roman columns, plywood panels, handicrafts, carved products, European white wood furniture, etc.;
Fourth, the tree species that are truly known as white wood should be recognized as a kind of commercial material in the international timber trade and market circulation, namely, China's purple sable; Southeast Asia's prismatic wood; African sycamore wood; American genus Liriodendron and other tree species.
Imitation white wood refers to the color, materiality and use of certain tree species in general compared with white wood, but it is not affiliated with scientific and technological data or the tree species recognized by the international timber trade. Due to the scarcity of white wood resources in the world, it is necessary to replace it with other woods. After long-term work practice, wood merchants and artisans choose Huangtongmu, Jielutongmu, Jupanmu, Tuanhuamu, South American bitter wood from Southeast Asia. A tree species similar to white wood, which has been finished with two sides of planed wood and flattened into flat sheets. The author once saw in the Dongyang Huadong Timber Market in Zhejiang Province and the Ningbo Modern Building Materials Market Plate City. The wood merchants generally referred to the plates processed by the above trees as white wood-Huangtongmu; Baimu-Jeruitong... for sale.
Nowadays, the national standard of redwood species is divided into five categories, eight categories and thirty-four species. It was implemented on August 1, 2000. The operating units are well documented, but the boundaries of white wood species are not yet available. White wood is one. A kind of expensive wood, a slight recognition error will seriously affect the consumer's economic interests and use effect. For this reason, the author has examined and verified many wood science and technology materials and international timber trade contracts, and divided the name and identification of white wood species. , nature, use of written, for comparison.
