As a commonly used wood material in railway engineering and mining, anti-corrosion sleepers have always been of great concern for their anti-corrosion ability. Oil immersion is considered a highly effective method in anti-corrosion treatment, as it allows the anti-corrosion oil to fully penetrate into the interior of the wood, greatly improving its anti-corrosion ability. There are also simple examples where paint is applied to the surface of wood for anti-corrosion purposes. However, the anti-corrosion ability of wood coated with paint is definitely not as strong as that of sleepers treated with oil immersion. So, will painting the anti-corrosion sleepers after oil immersion treatment have a better anti-corrosion effect? Is it necessary to brush it?
Let's start with the conclusion - it can be brushed, but it's not necessary. During the oil immersion treatment, the wood is placed in a specific container and immersed in anti-corrosion oil under high temperature and pressure, allowing the anti-corrosion oil to fully penetrate into the interior of the wood. This oil immersion treatment can effectively prevent the invasion of organisms such as fungi, fungi, and insects, as well as reduce the possibility of wood decay after being damp, thereby extending the service life of wood.
In contrast, painting is not very necessary for anti-corrosion sleepers after oil immersion treatment. Firstly, paint is just a surface coating that can only form a thin film covering the surface of wood, and cannot penetrate deep into the interior of wood like oil immersion treatment. That is to say, the anti-corrosion effect of paint is mostly limited to the surface of wood and cannot provide comprehensive protection like oil immersion treatment.
Even if painted, there is no significant impact or improvement on the anti-corrosion ability of oil immersed sleepers. The usage environment of materials such as sleepers is usually harsh. Even if painted, they will gradually age under the influence of natural environments such as sunlight and rain, causing problems such as peeling and cracking. The anti-corrosion effect is only on the surface of the wood. And the sleepers treated with oil not only have anti-corrosion oil inside, but also on the surface. The anti-corrosion ability of the surface itself is not weak, so applying paint on its surface is actually unnecessary.
Therefore, in summary, the anti-corrosion sleepers treated with oil immersion have already shown good anti-corrosion performance and do not require additional painting. The anti-corrosion sleepers treated with oil immersion not only extend their service life, but also reduce maintenance costs. When choosing anti-corrosion sleepers, choosing products that have been immersed in oil treatment would be a wiser choice.
