I don't know if you thought of "water-injected meat" when you saw the word "oil-injected sleeper". They may seem a little similar, but they are two very different things.
In railway construction, the sleeper is a very important component, which bears the weight of the train and keeps the track running. However, due to the perennial wind and rain, the sleeper is susceptible to corrosion, so it needs to be treated with anticorrosiveness. Normally, the anti-corrosion treatment is carried out by means of oil injection, so the anti-corrosion sleeper has the nickname of "oil-injected sleeper". So the question is, how is the oiled sleeper "oiled"? What kind of oil is infused? Next, let's briefly analyze.
Straight to the point, let's take a look at the oiling and anti-corrosion process of anticorrosive sleepers. Oil injection is a mechanical filling method, according to the pore size and density of the sleeper, the mechanical method with higher pressure is used to fill the void in the wood with oil quality to achieve the purpose of anti-corrosion. To put it in layman's terms, the sleeper is put into a specific equipment container, and the anticorrosive oil is immersed into the interior of the sleeper by high temperature and high pressure, so that the wood void inside the sleeper is filled with anticorrosive oil.
Most of the anticorrosive oils mentioned here are coal tar, decrystallized anthracene oil or tung oil, although these anticorrosive oils have a strong smell and are not suitable for indoor use, but the antiseptic ability improved by immersion in the sleepers is very gratifying. Moreover, the sleeper itself is not an indoor product, and its biggest role is still used for the laying and normal operation of railway tracks.
So, what are the advantages of the oil injection and anti-corrosion method of anticorrosive sleepers? First of all, the wood itself has good permeability, which allows the antiseptic oil to penetrate more fully into the interior of the wood, fill the pores and voids of the wood, form a uniform antiseptic layer, effectively resist the erosion of insects and fungi, and prolong the service life of the sleeper. Secondly, the oil injection anti-corrosion method is simple to construct, easy to operate, and more importantly, it can be processed on site, not limited by the seasonal climate, and can be maintained at any time to ensure the safety of railway operation. In addition, oil injection anti-corrosion can also improve the water resistance and wear resistance of wood, with good anti-corrosion effect, can reduce the frequency of sleeper replacement, reduce maintenance costs, and is also in line with the concept of sustainable development.
In general, the oiling and anti-corrosion method of anticorrosive sleepers is of great significance in railway construction and maintenance. Through the way of oil injection, the service life of the sleeper can be effectively extended, the safety and stability of the railway can be improved, the maintenance cost can be reduced, and the unity of economic, environmental protection and social benefits can be achieved. At the same time, it can also solve some problems in the oil injection method through continuous improvement and innovation, so as to make it more perfect. It is hoped that in the future, in the railway construction, the oil injection method can be more widely used and make greater contributions to the development of railway transportation.
