废橡胶微波再生法的实验研究

对不同胶种、不同硫化形态的废硫化橡胶在微波辐射下的再生过程进行实验研究。结果表明，炭黑填充硫黄硫化的极性和非极性废橡胶都可采用微波辐射再生，在频率为９１５ＭＨｚ的微波场中，粒径为３—５ｍｍ的废胶约辐射５ｍｉｎ，即可充分破坏硫黄文联网络，从而获得性能十分接近原胶的再生胶。

Experimental Study of Microwave Reclaim Technology

An experimental study was made on the reclaim process of various vulcanizates with the microwave radiation. The results showed that either polar or non-polar carbonblack-filled and sulfur-cured waste rubber could be reclaimed with the microwave radiation; the crosslink network of the rubber crumbs with 3-5mm of particle diameter could be sufficiently degradated after they exposed to the radiation for 5 min in the microwave field at 915 MHz frequency resulting in a reclaim with similar properties to those of the original rubber.
