Teach you how to solve the problem of wood drying

There are many factors that affect the natural drying of wood, which can usually be divided into the following three aspects:

1. The effect of air temperature and humidity

Natural drying takes advantage of the temperature, humidity and air movement of natural air. When naturally dried, the heat required to evaporate water in the wood is supplied naturally, so climate and weather have a major impact on natural drying. For example, in winter and summer, and in different regions, the drying speed is different. Another example is the difference in drying speed between winter and summer, and the climate of each region. For days when it is rainy or wet, the drying speed is slow. Although the winter climate is dry, the temperature is quite low, so there is very little evaporation of water, especially when the water freezes and the internal moisture stops moving, the drying is stopped. Although the temperature in the rainy season is high, it is suitable for the reproduction of fungi; in the summer, it is exposed to the sun, and it is prone to cracks due to rapid drying; when the climate is too humid, it is necessary to choose a well-ventilated place or a properly ventilated place to perform wood drying. Therefore, natural drying must pay attention to the local temperature, humidity and the strength of the wind. At the beginning, it is necessary to make appropriate choices and install the necessary facilities to assist according to meteorological conditions.

Drying in the rainy season is not very suitable. If the outer layer has dried to a certain extent during the rainy season, it is better. It takes half a year or even one year for the wood to dry and dry. It is more suitable to start drying in spring and spring in March. At this time, the temperature is slightly higher, and the fungus is less likely to occur. The moisture in the wood slowly evaporates. When it is warm, it has dried up. To a certain extent, during the rainy period, the moisture content of the wood is small, and the risk of insect decay and discoloration is very small. In the summer, although the temperature is high and the humidity is high, there is no danger of cracking, but it is good. Drying conditions.

2. The influence of stacking direction and wind direction

Naturally dry wood, the surrounding area is open, so the outside is dry quickly and the internal drying is slow. Therefore, air circulation needs to be good, so that the inside and outside are also dry. In order to make the interior of the wood pile well ventilated, it is necessary to properly select the skid and study the stacking method. Ordinary wood is stacked in parallel with the wind direction, and the effect is better. Therefore, it is necessary to study the local wind direction and then determine the direction of accumulation. If the wind is too strong, the wind receiving surface must be covered. The circulation of air is related to the level of the terrain and the surrounding state. When it is naturally dry, it is necessary to install appropriate equipment according to local conditions.

3. The influence of terrain and surrounding conditions

If the terrain has some slope, or the sand is well drained, the wood is dried on such a foundation and the results are good. In areas with poor drainage or wet conditions, not only poor drying, but also spoilage bacteria are easy to breed, and wood is easily damaged. Therefore, special attention should be paid to the drainage of foundations. There are tall buildings around, or surrounded by trees, or places with damp valleys, which are not suitable for natural drying, because when the places are dry, only the outer side of the pile is dry, and the bottom and inside will be corrupted; when it is necessary, it can be The foundation is raised, or the distance between the woods is increased, so that the air is easy to circulate, which is beneficial to the drying of the wood. The drying field is located in the countryside or in the mountain, which is advantageous in terms of technical conditions and economics than in the city.
