Railway sleepers, as a crucial part of the railway system, shoulder the heavy responsibility of supporting the tracks and maintaining track stability. The requirements for railway sleepers are not only strong bearing capacity and good stability, but also have certain corrosion resistance and wear resistance. After all, railway sleepers are mostly exposed to sunlight, rain, wind and sun, and are exposed to moisture and rain for a long time. If the sleepers do not have sufficient corrosion resistance, they are prone to aging, decay and other problems, which will affect the safety and service life of the railway. In order to ensure the long-term durability of railway sleepers, anti-corrosion technology is particularly important, especially oil immersion anti-corrosion technology, which plays a key role in the corrosion resistance and wear resistance of anti-corrosion sleepers.
Oil immersed anti-corrosion process: the "protector" of anti-corrosion sleepers
Oil immersed anti-corrosion technology refers to immersing sleepers in a specific anti-corrosion oil solution, so that their wood structure can absorb a certain amount of anti-corrosion oil and form a strong protective layer inside the wood. This protective layer can effectively prevent moisture from seeping in, reduce the contact between the wood and the external environment, and thus prevent the wood from rotting or deteriorating due to moisture.
Specifically, the anti-corrosion oil will penetrate into the interior of the wood through pressure soaking, with a depth of oil immersion usually exceeding 13 millimeters. This depth ensures sufficient protection for the interior of the wood, not only preventing moisture and bacterial damage, but also greatly delaying the aging rate of the wood.
Pine wood: the preferred material for railway sleepers
Pine wood is the most common type of wood used in the production of railway sleepers. Pine wood has good strength, toughness, and processability, and compared to other woods, it grows faster and has a relatively lower cost, making it the preferred material for making railway sleepers.
Oil immersion technology allows anti-corrosion oil to penetrate into the interior of pine wood, filling the pores of the wood. This not only enhances the wood's corrosion resistance, but also improves its wear resistance. Especially under the interaction of long-term friction between railway sleepers and wheels, as well as the invasion of wind and sand, oil immersed anti-corrosion sleepers can maintain longer stability and reduce the negative effects of wear and tear.
Corrosion resistance and wear resistance of anti-corrosion sleepers
The corrosion resistance and wear resistance of anti-corrosion sleepers are directly related to the safe operation of railways. If railway sleepers are not treated with anti-corrosion, they are prone to decay, deformation, and even breakage when exposed to humid environments and bacterial invasion, leading to railway instability and affecting train safety. And the sleepers that have undergone oil immersion anti-corrosion treatment, due to the anti-corrosion oil layer protection inside the wood, can not only resist the erosion of harmful substances such as moisture, bacteria, fungi, etc., but also delay the aging of the wood, ensuring its long-term stable operation.
In addition, the wear resistance of anti-corrosion sleepers is also one of the important properties of railway sleepers. The anti-corrosion oil not only protects the wood from wind, sun, rain, snow, frost, and friction between the sleepers and the crushed stones, but also increases the surface density of the sleepers, making them harder and effectively reducing the degree of wear and tear.
Application and practical effect of oil immersed anti-corrosion sleepers
Oil immersion anti-corrosion treatment has become a standardized part of the railway industry, and many railway companies have promoted and applied it as a basic process. Whether in China or abroad, anti-corrosion sleepers are an important component of railway construction. Under some special climatic conditions, oil immersed anti-corrosion sleepers are more suitable than other materials.
Conclusion
The oil immersed anti-corrosion process provides extremely effective protection for railway sleepers, enabling them to maintain high corrosion resistance and wear resistance even in the face of severe environmental tests. Through this process, railway sleepers can withstand long-term friction and corrosion exposed to moisture, which not only improves the safety and stability of the railway, but also extends the service life of the sleepers and reduces maintenance costs.
