功率超声波在废橡胶再生中的应用

全世界每年要产生一千五百多万吨废旧橡胶，由于废橡胶具有三维稳定的化学结构，需要很长时间才能降解，堆放在大自然中，既污染环境，又浪费宝贵的资源，废橡胶的回收利用是解决这一问题的最好方法。再生橡胶的制造方法很多，近来出现的超声波脱硫法具有高效、环保、产品质量高等优点，被认为是最有希望的方法，已受到广泛关注。详细地介绍功率超声波在废橡胶脱硫中的应用、介绍近年来国际上的进展情况和一些典型的装置，具有一定意义。

Application of power ultrasonic to devulcanization of waste rubber

It is estimated that currently about 15 million tons of waste rubbem are produced annually. Because of having steady three-dimensional chemical network, degradation of them needs long time and piling up them in the nature without being disposed, brings serious environmental pollution and wastage of valuable rubber. Reclaiming rubber from waste rubber is the best approach to solving this problem. In companions with several other methods, the ultrasonic devulcanization having advantages of high efficiency, no pollution and good quality is regarded as the most promising method. In this paper the applications of power ultrasonic to devulcanization of waste rubber was introduced in detail.
