Sleepers, as an important part of railways, bear the important responsibility of supporting railway tracks and running trains. In order to extend the service life of sleepers and prevent corrosion from moisture, bacteria, and fungi, anti-corrosion treatment is often used. There are several common anti-corrosion treatment methods currently available. Today, Qingdao Tiehan will focus on analyzing the differences and characteristics between the two treatment methods of coating anti-corrosion oil and oil immersion anti-corrosion oil.
Speaking of these two anti-corrosion methods separately, the main reason is that the sleepers treated with them look very similar, but their anti-corrosion ability is much worse.
The core point of using oil immersion to treat sleepers with anti-corrosion oil according to the formal process is to fully penetrate the anti-corrosion oil molecules into the fibers of the sleepers, achieving a deep anti-corrosion effect. In contrast, applying anti-corrosion oil only on the surface of the sleepers makes it difficult to penetrate into the interior of the sleepers. Therefore, after prolonged use, poor penetration of the coating method can still cause corrosion inside the sleepers. The anti-corrosion coating formed by oil immersion treatment is more uniform and firm, which can resist the erosion of external moisture, fungi, and bacteria for a long time.
In actual use, sleepers treated with anti-corrosion oil generally require frequent repair and supplementation in terms of anti-corrosion protection, because their surface layer is easily damaged by the external environment. Once damaged, if not repaired in a timely manner, sleepers are very prone to corrosion. The sleepers treated with oil immersed anti-corrosion oil do not require frequent maintenance and repair, and are relatively stronger in responding to environmental changes. This greatly reduces maintenance costs and workload, and can also reduce environmental pollution.
So when choosing oil immersed sleepers, we need to carefully distinguish and beware of painted sleepers impersonating oil immersed sleepers as "disguisers". Because sleepers treated with oil immersed anti-corrosion oil are more durable than those treated with anti-corrosion oil, they can maintain a long-lasting anti-corrosion effect. Due to the high production cost of oil immersed sleepers and the low production cost of painted sleepers, some businesses may use painted sleepers to impersonate oil immersed sleepers in order to obtain higher profits.
After analysis, we can clearly understand that sleepers treated with oil immersed anti-corrosion oil have significant advantages in anti-corrosion ability compared to sleepers treated with anti-corrosion oil. It has better penetration effect, longer anti-corrosion effect, and better durability. Therefore, when choosing oil immersed sleepers, we need to carefully distinguish whether the sleepers provided by the merchant are oil immersed or painted. After all, no one wants to buy "disguisers" - painted sleepers.
