Northern friends who have a lot of wooden furniture in their homes may find that in winter, furniture makes a "ba ga ba ga" sound. The reasons for this phenomenon are mostly due to changes in temperature and air humidity. In winter, when the temperature is low and the air is dry, furniture will undergo a certain degree of deformation, resulting in a "babbling" sound. Of course, not only furniture, but other wooden products also have similar situations, which can be considered a characteristic of wooden products. The anti-corrosion sleepers on railways are also made of wood and require drying treatment during the production process. So the question is, will the sleepers crack during the drying treatment?
Firstly, we need to understand what railway anti-corrosion sleepers are. Railway anti-corrosion sleepers are wooden components used to support rails on railways. After special treatment, they can be protected against corrosion and extend their service life. During the production process, railway anti-corrosion sleepers will undergo drying treatment to ensure that the moisture content in the wood meets the requirements and improve the stability and durability of the wood.
Wood may crack during the drying process, but railway anti-corrosion sleepers are not prone to this situation, mainly because the degree of drying is not as severe. Although in theory, the lower the moisture content inside the sleeper, the more anti-corrosion oil can be injected to achieve better anti-corrosion effects, the characteristics of the wood should also be considered during production. Generally, the moisture content in the wood should not exceed 15%.
Let me talk about how to dry the sleepers. Most sleeper manufacturers have only two ways to dry sleepers: natural drying and dryer drying. Compared to natural drying, the dryer creates a higher temperature environment, allowing the moisture in the wood to quickly evaporate. This method undoubtedly greatly improves production efficiency when production tasks are urgent.
Regardless of the drying method, as long as the degree of drying is well controlled and the proportion of moisture inside the wood is well controlled, sleepers are not easily cracked in this process. The sleepers that have successfully completed the drying process will then undergo special anti-corrosion treatment. The appropriate proportion of water and anti-corrosion oil immersion is more effective in preventing the wood from being corroded by bacteria, fungi, insects and other pests, improving the durability and stability of the wood.
In summary, railway anti-corrosion sleepers do not crack during drying treatment, mainly by controlling the proportion of moisture inside the wood. On this basis, anti-corrosion treatment can better improve the stability and durability of the wood. The application of these technologies not only ensures the quality of railway anti-corrosion sleepers, but also extends their service life, providing strong guarantees for the safety and smoothness of railway transportation.
