Whether it is selling furniture or studying wood culture, there are some basic wood common sense that must be understood. For example, trees are composed of three parts: the crown, the trunk and the root. For example, the trunk is the main source of wood. If you don't understand the wood and talk about furniture, you will not only lack the confidence, but also the suspicion of the class door.
In order to increase the ability to recognize wood, we must first start with the composition and structure of the trunk. Through the cross-section, the diameter section and the string section, we can understand the characteristics of the wood.
Cross section: A section perpendicular to the trunk that clearly reflects the basic characteristics of the wood and is the primary reference surface for identifying wood.
Diaphragmatic section: Parallel to the trunk and through the cut surface of the medulla, the diameter of the cut sheet is small and not easily deformed.
Chord section: A section that is parallel to the trunk but does not pass through the medulla. The annual rings are "V" shaped or wavy. The average wood is a string cut surface.
When identifying wood, it is necessary to have a standard three-section to fully understand the structure and properties of the wood. At the same time, if you want to know the wood, you must understand the structure of the wood. From the cross-section, you can see that the trunk is made of bark and layer. It is composed of xylem and marrow.
Bark: The outermost layer of the trunk. Different tree species have different colors, thicknesses, and appearances of bark. Therefore, bark is one of the most important bases for identifying tree species.
Forming layer: A thin layer of tissue between the bark and the xylem that needs to be viewed with a microscope and is the source of wood formation.
Xylem: The wood layer is formed inside the layer, which is the part we usually use.
The above is the macroscopic structural features of wood, which are wood features that can be seen by the naked eye or magnifying glass, including annual rings, early and late materials, side core materials, wood beams, tube holes, invaders, resin thieves, and axial thin-walled tissues. Wait. These features can be a direct tool for identifying wood, as shown in the table below.
Partial wood macrostructure characteristics table
Some wood species have similar appearance characteristics. They cannot be accurately identified and distinguished by the naked eye. It is necessary to understand the structure of the wood through the microscope, that is, the microstructure of the wood. It mainly includes the tracheid of the wood, the axial parenchyma cells, and the wood ray. Resin roads, etc., can also be seen in the above figure, because the content is too cumbersome to do more detailed introduction.
Mastering the skills of identifying wood requires familiarity with all aspects of wood. For example, wood can be identified by distinguishing the characteristics of the bark and the material, most of which identify the logs by paying attention to the characteristics of the bark. Such as color, shape, structure, section condition, cracking and peeling.
Partial bark recognition method:
The woodworking industry must first have the ability to identify wood, because the wood species and material properties will directly affect the processing equipment, methods and other content, such as the hardness of the wood, the hardness of different materials are the same, as long as They can be distinguished to better select the processing method and provide the work effect.
There are many methods for identifying wood, which are identified by means of hope, smell, question, touch, etc., as well as the use of wood identification search tables and wood perforated card recognition methods, as well as the use of modern information technology for wood identification, but then authoritative The identification of wood is also flawed, and people with rich knowledge cannot always identify wood accurately.
