Whether it is selling furniture or studying wood culture, there are some basic knowledge of wood that must be understood. For example, a tree is composed of a tree canopy, a tree trunk, and a tree root. For example, the trunk is the main source of wood. Do not understand wood furniture, not only lacked confidence, but also suspected of trespassing.
Whether it is selling furniture or studying wood culture, there are some basic knowledge of wood that must be understood. For example, a tree is composed of a tree canopy, a tree trunk, and a tree root. For example, the trunk is the main source of wood. Do not understand wood furniture, not only lacked confidence, but also suspected of trespassing.
In order to increase the recognition ability of wood, we must start with the composition and structure of the trunk. Through the cross-section, the radial section and the chord section, we can understand the characteristics of the wood.
Cross-section: The section perpendicular to the trunk, which clearly reflects the basic characteristics of the wood, is the most important reference surface for identifying wood.
Radial section: The plane parallel to the trunk and passing through the medullary heart, the radial plane sheet shrinks little and is not easily deformed.
Chord section: A section that is parallel to the trunk but does not pass through the medullary heart. The annual rings appear “V†shaped or wavy. Generally, the wood is a chord section.
When identifying wood, it must have standard three sections in order to fully understand the structure and properties of the wood; at the same time, if you want to understand the wood, you must understand the organization of the wood. From the cross section, you can see that the trunk is made of bark, forming layers, Composition of xylem and pith.
Bark: The outermost layer of the trunk, different tree species have different colors, thickness and appearance of the bark, so the bark is one of the very important basis for identifying the species of the log tree.
Formation layer: A thin layer of tissue between the bark and the xylem, which needs to be viewed with a microscope, is the source of wood formation.
Xylem: Within the formation layer are the wooden parts, which are the parts that we normally process.
The macro structural features of wood described above are wood characteristics that can be seen through the naked eye or magnifying glass, including annual rings, morning and evening materials, edge heartwood, wood rays, tube holes, intrusion bodies, resin steals, and axial parenchyma Wait. These features can be used as a direct tool to identify wood, as shown in the following table.
Part of the wood macrostructure characteristics
Some wood species have similar appearance characteristics. Using the naked eye can not accurately identify and distinguish, it is necessary to understand the structure of the wood through the microscope, that is, the microstructure of wood, which mainly includes wood tracheids, axial parenchyma cells, wood rays Resin channels, etc., which can also be seen in the above figure, will not be described in more detail because the content is too cumbersome.
To master the skill of identifying wood, it is necessary to be familiar with various aspects of wood properties. For example, wood can be identified by distinguishing the characteristics of the bark and the wood table. Most of the wood is identified by paying attention to the characteristics of the bark. Such as the color, shape, structure, cross-section conditions, cracking and peeling conditions.
Partial bark identification method:
Operators in the wood product processing industry must first have the ability to identify wood, because wood species and wood properties will directly affect the processing equipment, methods, and other content, such as the hardness of wood. The hardness of different wood species is the same, as long as the When they are distinguished, they can better choose processing methods and provide work results.
There are many methods for identifying wood, which are identified by means of sight, smell, question, touch, etc. There are also wood identification tables and timber perforated card identification methods. There is also wood identification through the use of modern information technology, but then the authority There are loopholes in the identification of the wood, and it is impossible for people with rich knowledge to consistently identify the wood.
