  • Info detail

该产品是针对铁路现有木枕和钢筋混凝土轨枕的技术不足及材料来源的限制,研制的高承载、抗疲劳、耐腐蚀的长纤维增强聚氨酯微孔泡沫复合材料。作为传统枕木的替代材料,可以克服木质轨枕不耐腐、资源短缺、寿命短的缺点和钢筋混凝土轨枕重量大、脆性大、减震效果差的缺点。该枕木便于施工,生产成本低,使用寿命长,易维护,可满足日益发展的高速铁路、城际高速及城市地铁和轻轨的建设需求。
 技术特点
   比重低:合成枕木比重为0.74±0.5g/cm³,与木材相近。
  强度好:合成枕木的各项强度性能指标均可通过国家权威试验机构认可,符合轨道交通的要求。在弯曲强度、弯曲杨氏模量、纵向压缩强度、剪断强度以及粘接剪断强度等方面均优于木材。
  加工性良好:合成枕木具有和木材一样的外形尺寸加工能力,同时还具有很多木材所不具备的优异性能,如可以通过修补剂对加工误差进行修补填充等。
