So what are the commonly used anti-corrosion treatment methods for sleepers? Let’s learn about it with Shibang Mining.
1. Application method: The preservative is painted or sprayed on the surface of the wood, and the solution gradually penetrates into the interior of the wood by the diffusion of the solution.
2. End penetration method: The preservative is placed at one end of the wood, and gradually penetrates into the conduit of the sapwood assembly line from here.
3. Impregnation method: Heat the wood in preservative for several hours, then take it out and let it cool, or take it out quickly and soak it in a cold solution for several hours.
Overview of anti-corrosion sleepers:
Anti-corrosion sleepers are also called oil-immersed sleepers, wooden sleepers, and oil-injected sleepers. Chemical solutions are injected into plain sleepers at high pressure to increase the anti-corrosion and waterproof performance of the sleepers. Hence the name anti-corrosion sleepers. Anti-corrosion sleepers are widely used in railways, coal mines, iron ore and other fields, but after all, they consume a lot of wood and will gradually be replaced by other products, such as concrete sleepers. Shibang Mining strives to improve the treatment process of anti-corrosion sleepers and try its best to extend the service life of anti-corrosion sleepers.
Anti-corrosion sleepers Anti-corrosion sleepers technology and materials
Anti-corrosion sleepers are treated with chemical methods. The wood sleepers are immersed in a mixed solution of coal tar and anthracene oil. After high temperature and high pressure, the wood absorbs the Preservatives are added to make them very hard, not only not easy to rot, but also waterproof, so antiseptic treated sleepers are not afraid of water.
Nowadays, the stronger and more durable Pinus sylvestris and larch wood are often used on railways to make sleepers. Wooden sleepers are rich in corrosion resistance and can absorb the weight of trains better than other sleepers.
Features of Shibang anti-corrosion sleepers
Main materials: radiata pine/slash pine/Douglas fir/larch/Pinus sylvestris, etc. It has good elasticity, light weight, simple production and good insulation performance. The connection between the fasteners and the wooden sleepers is simple, and the laying, maintenance and repair, and transportation are convenient. There is a large friction coefficient between the wooden sleepers and the gravel ballast. Wooden sleepers are rich in corrosion resistance and can absorb the weight generated by train running better than other sleepers and are not easy to break. However, the disadvantages of anti-corrosion sleepers are that they have a short service life and consume a large amount of wood. Wooden sleepers are prone to decay, mostly due to insect pests, environmental and climate influences, and the spike holes on the wooden sleepers will loosen due to long-term use, so general anti-corrosion sleepers only have a lifespan of more than ten years at most.
Product usage and scope of application:
Used for laying lines in railway track turnout areas.
