Abstract

A PRESENTE INVENÇÃO REFERE-SE A UMA PASTA CELULÓSICA DE CASCA DE EUCALYPTUS GLOBULUS PARA PRODUÇÃO DE PRODUTOS DE PAPEL TISSUE COM PROPRIEDADES PAPELEIRAS MELHORADAS. A PRESENTE INVENÇÃO ENGLOBA AINDA O PROCESSO DE PRODUÇÃO DESTA PASTA, ENVOLVENDO A SELEÇÃO DE APARAS DE CASCA, PRÉEXTRAÇÃO DA CASCA E COZIMENTO DAS APARAS COM HIDRÓXIDO DE SÓDIO E SULFURETO DE SÓDIO, DURANTE UM PERÍODO DE TEMPO DE PELO MENOS 200 MINUTOS E A UMA TEMPERATURA MÁXIMA DE 170°C. A INVENÇÃO DIVULGADA NESTE DOCUMENTO CONSIDERA TAMBÉM PAPEL TISSUE QUE INCORPORA A PASTA CELULÓSICA DE CASCA DE EUCALYPTUS GLOBULUS E O SEU USO COMO, POR EXEMPLO, PAPEL HIGIÉNICO, GUARDANAPO, PAPEL DE COZINHA E LENÇO DE PAPEL.THE PRESENT INVENTION REFERS TO A CELLULOSIC PULP OF EUCALYPTUS GLOBULUS SHELL FOR THE PRODUCTION OF TISSUE PAPER PRODUCTS WITH IMPROVED PAPER PROPERTIES. THIS INVENTION STILL ENGLISHES THE PRODUCTION PROCESS OF THIS PASTE, INVOLVING THE SELECTION OF SHELL APPLICATIONS, PRE-EXTRACTION OF THE APPLICATION AND COOKING OF APPLICATIONS WITH SODIUM HYDROXIDE AND SODIUM SULPHIDE FOR A MINUTE OF TIME OVER A LONG TIME FOR A LESS TIME OF 200 MINUTES. MAXIMUM 170 ° C. THE INVENTION DISCLOSED IN THIS DOCUMENT ALSO CONSIDERS TISSUE PAPER THAT INCORPORATES EUCALYPTUS GLOBULUS CELLULOSIC PASTE AND ITS USE AS, FOR EXAMPLE, HYGIENIC PAPER, NAPKIN, KITCHEN PAPER AND PAPER TISSUE.
