In the railway field, anti-corrosion sleepers play a very important role. It is a key component to support the rail and ensure the safe operation of the train. However, the production of anti-corrosion sleepers is not easy, which involves many technical details and processes. One link is to remove excess moisture from wood, and the quality of this link directly affects the overall quality of the final product. Then, let's discuss which is more suitable for the production of antiseptic sleepers, drying or drying.
First of all, we need to understand the principle and process of these two methods. Drying is to volatilize the moisture inside the wood by heating, so as to achieve the purpose of removing water. While drying is to place the wood in the air and let the natural wind dry the moisture in the wood. These two methods have their own advantages and disadvantages. Let's compare them.
The advantages of drying are fast speed and good effect. By controlling the heating temperature and time, the degree of moisture removal in wood can be more accurately controlled. And in the process of drying, it is carried out indoors. There is no need to worry about the impact of weather changes on drying, so it is convenient to accelerate the drying speed. This can not only improve production efficiency, shorten production cycle, but also ensure product quality. In addition, drying prevents the wood from being exposed to the wind and sun for a long time, thus reducing the possibility of water absorption and expansion of the wood.
Of course, the shortcomings of drying can not be ignored. First of all, drying requires a lot of energy, and the cost is high. If the operator's operation is not professional enough, long-term high-temperature heating may cause cracks in the wood and affect the service life.
In contrast, the advantage of air drying is the non-destructive drying in the natural environment, which will not cause additional damage to the wood. And drying is an energy-saving and environment-friendly way, without additional energy input. In addition, drying wood in the natural environment does not require too much manual intervention, saving a certain amount of manpower.
But the disadvantage of drying is more difficult to ignore. First of all, its speed is slower than drying, and it takes a relatively long time to achieve the same effect. In addition, in the process of drying, wood is easily affected by the external environment, such as rain, sunlight, etc., which may affect the quality of wood. In addition, if it is in a humid environment for a long time, the wood is not easy to dry, which is also easy to cause mold breeding and affect the product quality.
To sum up, for the production of anti-corrosion sleepers, drying and drying have their own advantages and disadvantages. In actual production, the most suitable way to remove excess moisture in wood can be selected according to the comprehensive consideration of wood types, process requirements and other factors. Or you can combine the advantages of drying and airing, and adopt a mixed method, such as drying first and then airing, to achieve the best effect. The ultimate goal is to produce more high-quality anti-corrosion sleepers and ensure the safety and smoothness of railway transportation.
