In the north, April is very dry, and occasionally you will hear elders say that "the wind is dry." The biggest feeling of friends in the north should be that they often feel dry inside the nose, and they may even have nosebleeds when they wash their face in the morning. As for the reasons, let's not go to the deep, today we will talk about the problem of "drying", in the environment of reduced air humidity, will not lead to the phenomenon of cracking of anti-corrosion sleepers.
In the field of railway, anticorrosive sleepers are a very common product, after anticorrosive treatment of sleepers can be protected from bacteria, fungi, insects, thereby extending its service life. However, there is a question, in dry weather conditions, the reduction of air humidity will cause the corrosion tie cracking phenomenon? After all, wood is a material filled in all aspects of our lives, and we all know that ordinary wood will crack when it is dry, and will it be the same for the antiseptic sleeper?
Before analyzing the effect of drying on the tie, we can understand how the anticorrosive tie is treated. Normally, the wood needs to be cut first, processed to a fixed size, then scored, and then dried to remove excess water from the wood. When the sleeper is treated with anticorrosion after scoring and drying, the anticorrosive oil can be immersed into the interior of the sleeper, so as to achieve better anticorrosion effect. The anticorrosive oil fills the surface of the sleeper and is immersed in the wood, which can effectively prevent water penetration, thereby reducing the water absorption rate and shrinkage rate of the wood, and then prevent wood deformation, cracking and other phenomena. Therefore, the effect of dry weather on the wood has been taken into account in the treatment process, and has certain drying resistance.
Normally in dry weather conditions, wood will lose part of the water, prone to dry cracking phenomenon. The particularity of the anticorrosive sleeper is reflected in its anticorrosive oil, which not only blocks the infiltration of external water, but also prevents the internal water from escaping, making the wood have a certain ability to resist drying. Even in a dry environment, anticorrosive sleepers can maintain a certain humidity, reducing the impact of drying and reducing the possibility of cracking.
In summary, the decrease of air humidity will not cause cracking of anticorrosive sleepers. On the contrary, the anticorrosive sleeper has taken into account the effect of dry weather on the wood in the surface treatment and its own performance, and has certain drying resistance. Even in the dry month of April, it will not have much effect on the anticorrosive ties on the railway. Of course, the normal maintenance frequency still needs to be maintained, when the anticorrosive impregnated oil layer is worn and broken, it still needs to be treated in time, otherwise there will be cracking and other phenomena, affecting the safety of the railway system.
