<p>Mechanical/chemical method and composition for devulcanization of rubber maintains the macromolecules, renders sulfur passive for later re- vulcanization, as show in Figure 1, is cost effective, enviromentally friend ly and produces high quality de-vulcanized rubber to replace virgin rubber. Was te rubber is shredded, crushed and metal-removed. Modifying composition is adde d as the particles of shredded waste rubber are poured between two rollers tha t further crush the particles. The modifying composition is a mixture of a proton donor, an organic acid, an inhibitor a friction agent. The particles are subjected to at least 10 sets of rollers.</p> |
