Abstract
"POLPAçãO MECáNICA AP DE MúLTIPLOS ESTáGIOS COM TRATAMENTO DE LINHA DE SOPRO COM REFINADOR". A presente invenção refere-se a etapa de adição de substâncias químicas tal como peróxido alcalino em uma linha intermediária depois da refinação, com a etapa de aplicação de substãncias químicas tal como peróxido alcalino como um pré-tratamento antes da refinação primária e/ou aplicação de substâncias químicas tal como peróxido alcalino no refinador primário. Isso é implementado na modalidade preferida, por material, refinando o material em uma polpa em um refinador superatmosférico, e adicionando substâncias químicas na linha de sopro após a refinação."MECHANICAL AP POLLATION OF MULTIPLE STAGES WITH BLOW LINE TREATMENT WITH REFINER". The present invention relates to the step of adding chemicals such as alkaline peroxide to an intermediate line after refining, with the step of applying chemicals such as alkaline peroxide as a pretreatment prior to primary refining and / or application. of chemicals such as alkaline peroxide in the primary refiner. This is implemented in the preferred embodiment per material by refining the material into a pulp in a superatmospheric refiner and adding chemicals to the blow line after refining.
