Wood is the favorite material of mankind and involves almost every corner of the human world. During the hundreds of years of research and debugging, humans have basically mastered the various properties of wood, and also injected a lot of effort into wood processing, the most important of which is dry wood.
Whether used as a structural support in a building or as a woodworking plans item, the wood absorbs or releases moisture until it is in balance with the surrounding environment. This process of communicating with the surrounding environment can cause uneven shrinkage of the wood, which can damage the wood if the process occurs too quickly.
If the trees are dried immediately after felling, they can also protect the wood from decay, fungal contamination, insect attacks and the like. Organisms that cause decay and stains usually cannot thrive in wood with a moisture content of less than 20%. All the pests can only live in fresh logs, so timely drying can improve the quality of the wood.
In addition to the above advantages of wood drying, the following points are also important:
1. The dry wood is lighter and the transportation and handling costs are reduced.
2. In most strength properties, dry wood is stronger than fresh logs.
3. If proper penetration is to be carried out, especially in the case of oil-based preservatives, the wood impregnated with the preservative must be properly dried.
4. In the field of chemical modification of wood and woodworking plans, the material should be dried to a certain moisture content for adequate reaction.
