This review deals with waste rubber recycling by devulcanization treatment using microwave method. In fact, vulcanized rubbers have been extensively used in various fields due to their superior performances. Subsequently, the massive use of such materials, especially in the automotive industry, has generated a substantial amount of wastes which are not easily to be degraded due to the three-dimensional network formed by the vulcanization process. One of the optimal solutions for the successful recycling of rubber is devulcanization, i.e., the process in which the sulfur bonds in the vulcanized material are selectively broken. Currently, to achieve rubber devulcanization, the microwave treatment has been proposed as a promising alternative process due to its precise manipulation of process variables. Furthermore, the microwave process is easily to be coupled with effects of other elements such as chemical and swelling agents. In this work, different microwave devulcanization methods are reviewed, the utilization of the corresponding devulcanized materials has also been discussed. The reviewed contents are believed to be of great interest to academics and industries since they represent a great challenge from scientific, economic and environmental points of view.
这篇综述主要讨论了利用微波法进行废橡胶脱硫再生的方法。事实上，由于硫化橡胶具有优异的性能，因此被广泛应用于各个领域。随后，由于硫化过程中形成的三维网络，这类材料（尤其是在汽车工业中）的大量使用产生了大量难以降解的废物。成功回收橡胶的最佳解决方案之一是脱硫，即选择性地破坏硫化材料中的硫键的过程。目前，为了实现橡胶脱硫，微波处理已被提议作为一种很有前途的替代工艺，因为它可以精确控制工艺变量。此外，微波工艺很容易与化学试剂和膨胀剂等其他元素的作用相结合。在这项工作中，综述了不同的微波脱硫方法，还讨论了相应的脱硫材料的利用。鉴于从科学、经济和环境的角度来看，这是一个巨大的挑战，相信这些综述内容将引起学术界和工业界的极大兴趣。
