Anti corrosion sleepers are an essential component of railway construction and maintenance. When we mention sleepers, many people's first reaction should be: aren't they just the pieces of wood laid under the railway tracks? That's right, it's indeed a piece of wood, but the sleepers are not ordinary wood. Professional railway sleepers have a unique manufacturing process, and the oiling process is particularly crucial.
The oil injection process is the core link in the production of anti-corrosion sleepers. Engineers use a series of carefully designed steps to apply specially formulated anti-corrosion oil to professional equipment, subjecting it to high temperature and high pressure environments, allowing the anti-corrosion oil to deeply penetrate into the interior of the wood, forming a strong anti-corrosion layer. This is completely different from simple surface coating, which can provide long-term effective anti-corrosion function for sleepers.
From the beginning of raw material procurement, we need to choose high-quality wood. Common anti-corrosion sleeper materials include pine, oak, and other corrosion-resistant wood species. These woods have natural anti-corrosion properties, but further processing is needed to better cope with the harsh challenges of railway environments. Next is the immersion stage. We will place the pre dried wood in a sealed pressure tank and inject special anti-corrosion oil. In high temperature and high pressure environments, anti-corrosion oil will penetrate deep into the wood texture and fill the gaps inside it. This process requires strict control of time and temperature to ensure that the anti-corrosion oil is fully penetrated.
After immersion, the surface of the sleepers becomes oil black. This black anti-corrosion is achieved by covering the sleepers with a layer of "armor", which has the ability to resist external factors such as moisture and microorganisms that can easily cause corrosion of the sleepers. This "oiling" method has multiple advantages compared to simple painting:
Firstly, the anti-corrosion effect is more long-lasting. Surface coating is prone to gradually peel off due to wind and sun exposure, but immersion treatment can firmly embed the anti-corrosion oil into the interior of the wood, forming long-term protection. Even if there is slight wear on the surface, it will not affect the overall anti-corrosion performance.
Secondly, it has stronger resistance to environmental corrosion. The railway environment is complex and ever-changing, requiring resistance not only to moisture, but also to acid and alkali, and even to biological invasion. Oil injection treatment can protect sleepers from various corrosive factors and ensure their service life.
Thirdly, maintenance costs are lower. Ordinary surface painting requires regular touch ups, which incurs high maintenance costs. And completing the oil injection treatment in one go can have a long-term effect, greatly reducing subsequent maintenance expenses.
Of course, the production of anti-corrosion sleepers is not achieved overnight. It requires a complex process flow, among which the oil injection step is particularly crucial. Only through careful research and continuous optimization of every aspect, can we create high-quality products that truly stand the test of time.
This is the unique insight of professional railway engineers into the production of anti-corrosion sleepers. The clever design of the oil injection process injects lasting vitality into the sleepers, enabling them to withstand various harsh environmental tests. I believe that through this advanced manufacturing process, we can definitely contribute more to the railway industry.
