Abstract

Inventia se refera la un procedeu pentru regenerarea cauciucului natural prin tratare cu abur, care executa omogenizarea deseurilor de cauciuc pe un valt cu suprafata neteda, având un coeficient de frictiune ridicat egal cu 1:2,8, prin treceri succesive, urmata de devulcanizare cu abur la 4...5 at si 140...150 degree C.The invention relates to a process for the regeneration of natural rubber by steam treatment which performs the homogenisation of rubber wastes on a smooth surface with a high coefficient of friction equal to 1: 2.8, by successive passes, followed by devulcanization with steam at 4 ... 5 at and 140 ... 150 degrees C.
