Abstract

PROCESSO PARA ATIVAçãO DE SUPERFìCIE E/OU DESVULCANIZAçãO DE PARTìCULAS DE BORRACHA VULCANIZADA POR ENXOFRE. A presente invenção refere-se a um processo para ativação de superfície e/ou desvulcanização de partículas de borracha vulcanizada por enxofre. A fim de romper as pontes de enxofre e reduzir o enxofre, as partículas de borracha são tratadas de uma maneira biotecnolócica em um meio com bactérias anaeróbicas mesofilicas e/ou opcionalmente anaeróbicas e/ou microaerofílicas e/ou com um ou mais sistemas de enzima de tais bactérias. As partículas de borracha ativadas, desse modo tratadas, mostram propriedades de vulcanização melhoradas, em comparação com partículas de borracha não tratadas, e permitem a produção de artigos de melhor qualidade.
