Abstract

The resource reclamation of waste tire rubber (WTR) is regarded as the most suitable strategy for these solid wastes. Water jet pulverization (WJPul) is a sustainable reclamation technique for WTR, since both size reduction and rubber devulcanization can be achieved. Aiming at understanding the mechanisms related with pulverization and devulcanization of WTR, this work detailed the interactions between WTR and high pressure water jet (HPWJ). The results show that WJPul can be defined as a mechanochemical process for WTR. The compressive shear failure of rubber mainly induces rubber devulcanization and results in fine ground tire rubber (GTR) particles, HPWJ erosion mainly intensifies rubber depolymerization and results in coarse GTR particles. Chemical reactions can be detected between the devulcanized GTR from WJPul and asphalts, thus resulting in better modification performances of GTR from WJPul in asphalt. The results can help better understand the WJPul mechanisms and provide guidelines for WJPul application.
高压水射流粉碎废轮胎橡胶的机械化学脱硫研究
废旧轮胎橡胶的资源化利用被认为是处理该类固体废弃物最合适的策略。水射流粉碎(WJPul)是一种可持续的再生技术,因为它既可以实现减粒径,又可以实现橡胶的脱硫。为了了解水粉碎机粉碎和脱硫的相关机理,本文详细研究了水粉碎机与高压水射流(HPWJ)的相互作用。结果表明,WJPul可定义为WTR的机械化学过程。橡胶的压缩剪切破坏主要导致橡胶脱硫化,形成细磨轮胎橡胶颗粒;高压水射流侵蚀主要加剧橡胶解聚,形成粗磨轮胎橡胶颗粒。WJPul改性后的GTR与沥青发生了化学反应,从而使WJPul改性后的GTR在沥青中的改性性能更好。研究结果有助于更好地理解WJPul机制,并为WJPul应用提供指导。
