1, prevent wood deterioration and decay, extend the life of wood products.

Wet wood stacked in the outdoor air for a long time, if no corresponding treatment measures are taken, it is easy to cause rot and insect pests. Reducing the moisture content of wood to less than 20% can greatly reduce the damage to microorganisms and pests. Therefore, usually in the production and processing sector, the wood is dried to a moisture content of about 8-15%. This not only ensures the inherent properties and strength of the wood, but also improves the corrosion resistance of the wood.

2, reduce the weight of wood, is conducive to improving the load capacity of the vehicle.

Freshly cut wood, its moisture content even exceeds its own weight, after a short time of storage, natural drying, its water content is still very high. After the wood is dried indoors, the weight can be reduced by 30-50%, which is conducive to improving the loading capacity of the vehicle.

3, improve the mechanical strength of wood and wood products, improve the physical properties of wood.

When the fiber saturation point is lower, the physical and mechanical strength of wood increases with the decrease of wood moisture content. At the same time, the wood is also easy to be sawed and planed, thereby reducing the loss of woodworking machinery.

4. Prevent deformation and cracking of parts.

When the water in the wood is expelled into the air, it causes the volume of the wood to shrink. If the shrinkage is not uniform, the wood will crack or deform. If the dried wood reaches the level that is compatible with the use environment or the use requirements, the volume and size of the wood can be kept relatively stable and the durability is good.
