铁道混凝土枕轨下所用的橡胶垫板是在钢轨和混凝土枕之间起缓冲作用的弹性橡胶垫板。随着铁道运输业的高速发展,对道轨垫板的质量稳定性要求越来越高。针对产品生产过程中所出现的质量不稳定问题,采用橡胶功能助剂JC-069代替少量炭黑和部分无机补强剂,用以提高产品性能和质量稳定性。现将技术服务过程中的试验内容和试验效果作一简要介绍。 Rubber slabs used under railway concrete sleepers are elastic rubber pads that act as a buffer between rail and concrete sleepers. With the rapid development of the railway transportation industry, the quality and stability of the track pad are getting higher and higher. In view of the quality instability occurred in the production process of the product, rubber functional additive JC-069 was used instead of a small amount of carbon black and some inorganic reinforcing agents to improve product performance and quality stability. Now the technical services in the process of testing and test results for a brief introduction.
