Anti-corrosion sleepers Anti-corrosion sleepers have good elasticity, are light in weight, are simple to make, and have good insulation properties. The connection between fasteners and wooden sleepers is simple to lay, maintain and repair, and easy to transport. There is a large friction coefficient between wooden sleepers and gravel ballast. Wooden sleepers are rich in ductile corrosion and can absorb the weight generated by train running better than other sleepers and are not easy to break. The disadvantage of anti-corrosion sleepers is that they have a short service life and consume a large amount of wood. The reasons why wooden sleepers are prone to decay are mostly caused by insect pests, environment and climate. Moreover, the spike holes on the wooden sleepers will loosen due to long-term use, so the lifespan of ordinary anti-corrosion sleepers is only more than ten years at most.
Treatment technology and materials of anti-corrosion sleepers
1. Treatment technology of anti-corrosion sleepers
Anti-corrosion sleepers are treated with chemical methods by immersing wood sleepers in a mixed solution of coal tar and anthracene oil. The high-temperature and high-pressure wood has absorbed this preservative and becomes very hard. Not only is it not easy to rot, but it is also waterproof, so the sleepers that have been treated with antiseptic treatment are not afraid of water.
2. Material of anti-corrosion sleepers
Nowadays, the stronger and more durable Pinus sylvestris and larch wood are mostly used on railways as the wood for making sleepers. Wooden sleepers are rich in corrosion resistance and can absorb the stress of train travel better than other sleepers. The weight produced.
