Moisture in wood can move inside the wood under certain conditions, which is called moisture conductivity of wood. Moisture can drain from both ends of the wood by moving along the fiber direction, or it can drain from the sides of the wood across the fiber direction, and in most boards, the length is much greater than the thickness width. The side area of ​​the sheet is much larger than the end area. Therefore, although the conduction of moisture along the fibers is easier than that across the fibers, it is the conduction across the fibers that plays a decisive role in wood drying.

Before the wood drying kiln is used, a comprehensive and detailed inspection of its shell and equipment must be carried out to ensure the normal operation of the drying process. The specific inspection contents are as follows:(4) the formulation of drying process.

The thermal modification of wood, also known as carbonization treatment, is the formation of carbonized wood by long-term pyrolysis treatment of wood with overheated steam at 160C~230C. Compared with chemical modification technology, thermal modification process and equipment are simpler, environmentally friendly, and have significant economic benefits. It has been widely used both domestically and internationally.

Carbonized wood is a homogeneous carbonization treatment of wood using high temperature without any chemical agents, so that the surface of the wood has a dark brown aesthetic effect, and has anti-corrosion and anti-biological invasion effects. It is stable, does not deform, is completely degreased and does not overflow, has good thermal insulation properties, is simple to construct, easy to paint, and has no special smell. It is an ideal indoor and sauna material and has become a new trend in bathroom decoration; it is anti-rot and anti-insect It is resistant to moth, deformation and cracking, and high temperature resistance, making it an ideal material for outdoor swimming pool landscapes.

The improvement in biodurability of thermally modified materials is due to the following reasons. -During the thermal degradation of wood, acidic substances such as acetic acid and formic acid are generated, which affects the metabolic process of decay bacteria in the heat-treated wood, thus enhancing the corrosion resistance.

Attention during the wood drying process: When the wood is first put into the kiln, it is in a low-temperature preheating and humidification process. The dry bulb temperature for low-temperature preheating is generally within the range of 35-45 ℃.

Wood drying machine is one of the wood working machines,today we’ll talk about the basic safety rules for wood working machines. Basic safety rules for wood working machines 1. Use mechanical feeding wherever possible. 2. Enclose all cutters and saw blades as far as practicable. 3. Ensure all machines are well maintained. 4. Ensure adequate lighting at every machine.

About the wood drying kiln steps and matters needing attention of choose and buy,today for everyone to introduce:

Before the drying kiln is used, a comprehensive and detailed inspection of its shell and equipment must be carried out to ensure the normal operation of the drying process. The specific inspection contents are as follows:

Firstly, it is necessary to understand a little about the moisture carrying capacity of air. A cubic metre of air at 20 deg. centigrade and 100% relative humidity will hold around 14 grams of water. If you were to heat the same cubic metre of air up to 70 deg. centigrade it would be holding around 400 grams of water at 100% relative humidity.
