Development railroad track bed ties

项目摘要

The conventional railroad ties always have lifetime problems and there are few options available for reusing or recycling. Alternative products with longer lifetime and better properties are therefore becoming increasingly important by railroad operators. On the other hand, the increasing amount of discarded tires, which needs special storage or landfill, also poses environmental issues. The rubber based railroad ties from the discard tiers are anticipated to have better application properties and longer lifetime than the conventional wooden railroad ties. Such tire-enabled railroad ties would have a great potential to meet the requirement of alternative railroad ties and provide value-added utilization of scrap tires. In this proposed project, the recycled rubber fragments will be employed for the major content of railroad ties along with suitable additives and compatibiliser agents. Planned optimization studies will enable to improve the mechanical and other required characteristics. The samples made by using materials described herein will be characterized for its own hardness, strength, durability, nail-gripping and other properties required by using as railroad ties. After initial compounding/formulation carried out at CBBP, U of Toronto, the prototype railroad ties will be developed through high pressure molding machine available at industry partner, Windsor Rubber.

传统的铁路枕木总是存在寿命问题，并且很少有可用于再利用或回收的选择。因此，具有更长寿命和更好性能的替代产品对铁路运营商变得越来越重要。另一方面，需要特殊储存或填埋的废弃轮胎数量不断增加，也带来了环境问题。预计来自废弃层的橡胶基铁路枕木比传统的木制铁路枕木具有更好的应用性能和更长的寿命。这样的轮胎使铁路枕木将具有很大的潜力，以满足替代铁路枕木的要求，并提供增值利用的废轮胎。在本项目中，再生橡胶碎片将与合适的添加剂和相容剂一起用于铁路枕木的主要内容沿着。计划的优化研究将能够改善机械和其他所需的特性。通过使用本文所述的材料制成的样品的特征在于其自身的硬度、强度、耐久性、夹钉性和用作铁路枕木所需的其他性质。在多伦多的CBBP进行初始混合/配制后，将通过行业合作伙伴温莎橡胶公司提供的高压成型机开发铁路枕木原型。
