High load polyurethane sleepers

Product Introduction The product is inadequate for existing railway wooden pillow and reinforced concrete sleepers and to limit the source material, the development of high load, fatigue, corrosion resistant long fiber reinforced composite microporous polyurethane foam. As an alternative to traditional materials sleepers, wooden sleepers can be overcome not decay, large shortage of resources, the short life of the shortcomings and reinforced concrete sleepers weight, brittleness, damping effect is poor shortcomings. The sleepers ease of construction, low production costs, long life, easy maintenance, to meet the growing high-speed rail, intercity high-speed and urban subway and light rail construction needs. Technical Features ① low specific gravity: Synthetic sleepers gravity of 0.74 ± 0.5g / cm3, and timber similar. ② good strength: the strength of the performance of synthetic sleepers can be recognized by the national authority of the testing facility, in line with the requirements of rail traffic. In the flexural strength, flexural Young's modulus, longitudinal compression strength, shear strength and shear adhesion strength were better than wood. ③ good workability: synthetic sleepers have the same dimensions and timber processing capacity, but also has a lot of wood do not have superior properties, such as machining errors can be repaired Putty to fill and so on.
