process for surface activation and / or devulcanization of sulfur vulcanized rubber particles

摘要

PROCESS FOR SURFACE ACTIVATION AND / OR DEVULCANIZATION OF SULFUR VULCANIZED RUBBER PARTICULARS. The present invention relates to a process for surface activation and / or devulcanization of sulfur vulcanized rubber particles. In order to break sulfur bridges and reduce sulfur, rubber particles are biotechnologically treated in a medium with anaerobic mesophilic and / or optionally anaerobic and / or microaerophilic bacteria and / or one or more enzyme systems. such bacteria. The activated rubber particles thus treated show improved vulcanization properties compared to untreated rubber particles and allow the production of better quality articles.
