    传统的木头枕木寿命比较短,有开裂、腐烂、虫蛀等问题,于是采用一些比较特殊的木材,如柞木等,并进行防虫、防水、耐火等处理。虽然这样,随着现代铁路的扩展,这些木材来源紧张,而且,随着速度和载重的提高,木枕无法满足需要。

     塑料枕木除具有木材的优点以外,还具有尺寸稳定、承载能力强、抗冲击能力高、耐油耐磨、耐环境侵蚀、防水防风化、防白蚁防腐食、绝缘性能高等等。

    塑料枕木具有免维护、免油漆、可循环利用,经过检测可以在-37℃~90℃的温度范围正常使用。

    The life of traditional wooden sleeper is shorter, have the problem such as craze, rot, moth-eaten, use a few more special lumber then, wait like oak wood, undertake prevent insect, waterproof, fire resistance to wait for processing. However, with the expansion of modern railways, these sources of wood are tight and, with increasing speed and load, the wooden pillows are unable to meet the demand.

    In addition to the advantages of wood, plastic sleepers also have a stable size, strong bearing capacity, high impact resistance, oil resistance and wear resistance, environmental erosion resistance, water resistance and weathering resistance, protection against termite corrosion, high insulation performance and so on.

    Plastic sleepers with free maintenance, free paint, recycled, tested in 37 ℃ ~ 90 ℃ temperature range of normal use.
