In railway engineering, anti-corrosion sleepers are a crucial material that plays a role in supporting and dispersing the weight of railway tracks. This summer in the north, high temperatures and direct sunlight have caused unbearable suffering for outdoor workers. So, what kind of impact will this have on the anti-corrosion sleepers on railways? Will the deformation of the sleepers occur due to the principle of "thermal expansion and contraction"? Next, Qingdao Tiehan will briefly analyze it with everyone.
Railway anti-corrosion sleepers are made using special processing techniques, which enable them to withstand high temperatures and exposure to sunlight. In terms of material selection, we have chosen high-quality wood that is resistant to high temperatures, such as New Zealand pine or oak. These woods have high density and stability, which can effectively alleviate the effects of high temperature and exposure to sunlight.
The key to choosing wood is the method of anti-corrosion treatment, which can better cope with the high temperature and exposure in summer. The common method for anti-corrosion treatment is to use professional anti-corrosion oil for immersion treatment. By using professional equipment, the wood is placed in a high-temperature and high-pressure environment, allowing the anti-corrosion oil to better penetrate the interior of the wood and form a layer of anti-corrosion protection, effectively preventing the infiltration of moisture. Of course, this surface treatment can also prevent wood from rotting and being invaded by pests, extending its service life.
Let's talk about 'thermal expansion and contraction' again. For wood, this is a big problem that requires finding ways to deal with it. Usually, manufacturers of anti-corrosion sleepers will perform surface scoring treatment on the sleepers before anti-corrosion treatment. The so-called "scoring" refers to using a scoring machine to mark some fine seams with a depth of less than 13mm on the surface of the sleeper according to the track, and the spacing between the fine seams is strictly required. In order to facilitate the better penetration of anti-corrosion oil into the interior of the sleepers during oil immersion treatment.
From this perspective, scratch treatment can be described as killing two birds with one stone. It not only allows the anti-corrosion oil to better penetrate the interior of the sleepers, but also provides room for expansion in high-temperature environments. This unique performance enables anti-corrosion sleepers to self regulate under high temperature and exposure conditions, reducing the risk of deformation.
In addition, the design of anti-corrosion sleepers also fully considers the effects of high temperature and exposure to sunlight. They usually have a larger cross-sectional area and thickness to increase their stability and deformation resistance. In addition, the shape and structure of the sleepers have been carefully designed to enhance their resistance to high temperatures and exposure to sunlight.
In summary, railway anti-corrosion sleepers have strong resistance to high temperatures and exposure to sunlight, and are not easily deformed. This is due to its special processing technology, including the selection of high-temperature resistant wood, scoring treatment, surface anti-corrosion oil immersion treatment, and excellent thermal expansion and contraction performance. These factors enable anti-corrosion sleepers to withstand high temperatures and exposure to sunlight for extended periods of time in northern summer, ensuring the safe and stable operation of railway lines.
