When purchasing boards, it is important to understand the raw materials of the boards, so that you can have a clearer understanding of the relevant characteristics of the boards. Next, the editor will help you understand the board from the wood, let's take a look together.
1. What is the structure of tree bark?
To understand wood, one must first understand the composition of the trunk and bark. The trunk is the most basic structure of a tree. If viewed through a cross-section, the trunk's structure includes bark, cambium, xylem, and pith. The bark is the outermost layer of the trunk, encompassing all tissues outside the cambium. The bark can be further divided into the exoderm, periderm, and endoderm. The cambium, located primarily between the phloem and xylem of the trunk, is a narrow, meristematic layer capable of generating mother cells and daughter cells. The xylem, located between the cambium and pith, is the most economically valuable part of the trunk and the most important component of the wood. The pith, located in the center of the trunk and tightly surrounded by the xylem, is a thin-walled tissue that primarily transports and stores nutrients, maintaining healthy growth.
2. What is the structure of wood?
The structure of wood is also very interesting. It can be simply divided into three sections: the transverse section, the radial section, and the tangential section. Cutting wood according to different sections can produce different grain patterns in flooring. The transverse section is perpendicular to the main axis of the trunk. Besides the growth rings, all grain characteristics of the trunk can be understood through this section. The transverse section is the best way to judge the quality of wood because it is very hard and wear-resistant, and can also be used as paving blocks. The radial section is parallel to the main axis of the trunk and passes through the pith. This section produces less shrinkage and is less prone to warping, making it suitable for making wooden rulers or musical instrument soundboards. The tangential section is also parallel to the main axis of the trunk, does not pass through the pith, and is not tangential to the growth rings. It is a tangent line from one growth ring to another. The physical properties of wood are that its integrity and chemical composition are not affected.
The above is what the editor shared with you about selecting and making boards. China Board Network takes you to understand the relevant content starting from wood. I hope the above content of the editor can be helpful to everyone.
