玻石钢^?复合材料轨枕-简介

玻石钢^?铁路复合轨枕外观与木枕相似，施工安装容易，热膨胀系数与导热率低、抗震、抗压、抗拉、抗弯强度大，使用寿命长；具有防水、防火、防虫、防腐、无毒、无辐射、零甲醛、绿色环保、可回收再利用特性，可保持良好的电绝缘性能，在长期恶劣气候条件下也保持稳定。其现场加工性能大大优于混凝土，重量轻，可制成任意长度，不需为每种长度另制模具。其生态性能也是一大优点，制造时不使用溶剂，使用后可以循环利用。钉孔修补后，可再次使用。使用寿命长、施工费用低、维修费用低、节省大量的人力物力和财力，使产品周期成本及总成本降低。它可用普通木工工具进行锯、刨、钉、上螺丝和胶粘等加工。

复合材料枕木具有40~50年的使用寿命，性价比高。国产设备及原材料供应充足，可按工程进展及时扩大生产能力。

----  Glasstonesteel^? Composite material Sleeper  ----

 

Glasstonesteel^? composite material sleeper - Brief introduction:

 

Glasstonesteel^? composite material sleeper appearance similar with timber sleeper, easy for construction and installation, low coefficient of thermal expansion and heat conductivity, great anti-seismic, crush resistance, tensile strength, bending strength, long service life; has the characteristics: waterproof, fireproof, insect prevention, corrosion prevention, non-toxic, no radiation, zero formaldehyde, green and environmental protection, recycling and reusing, keep good electrical insulation property, remain stable under long atrocious weather condition. The field process performance is superior to reinforced concrete, low weight, may be made out random lengths, need not to make mould for each length. The ecological performance is also a big advantage, manufacture without the use of solvents, can be recycled after use. Repair the tack hole, then reuse, long service life, low construction fee, low maintain fee, save up vast manpower and material and financial resources, make the product life cycle cost and total cost reduction. That sleeper may be processed by common wood working tool, such as sawing, plane, nail, screw, and stick with glue, etc.

That composite material sleeper has 40-50 years service life, high cost performance. There has plenty supply for domestic equipment and raw materials, may enlarge the production capacity in time in accordance with project progress.
