Abstract

A PRESENTE INVENÇÃO DIZ RESPEITO A FORMULAÇÕES PARA TRATAMENTO DE SUPERFÍCIE DE SUBSTRATOS CELULÓSICOS QUE COMPREENDEM HIDROCLORETO DE BETAÍNA E AGENTES DE TRATAMENTO SUPERFICIAIS, EM QUANTIDADES, EM MASSA, POR PESO TOTAL DE SÓLIDOS SECOS, DE ENTRE 5 A 20 % DE HIDROCLORETO DE BETAÍNA E ATÉ 95 % DE AGENTES DE TRATAMENTO SUPERFICIAIS. AS FORMULAÇÕES DESCRITAS NESTA INVENÇÃO PERMITEM A OBTENÇÃO DE SUBSTRATOS CELULÓSICOS COM PROPRIEDADES DE IMPRESSÃO EQUIPARÁVEIS OU ACRESCIDAS FACE AOS SUBSTRATOS QUE INCLUEM OS ADITIVOS COMUMENTE USADOS NA INDUSTRIA DE PASTA E DE PAPEL. ADICIONALMENTE, AS FORMULAÇÕES DESCRITAS PERMITEM UMA REDUÇÃO DO CONSUMO DE AGENTES BRANQUEADORES ÓTICOS, E CUSTOS ASSOCIADOS, UMA VEZ QUE NÃO PROMOVEM O FENÓMENO DE QUENCHING, ISTO É, A DIMINUIÇÃO DO EFEITO DE BRANCURA POTENCIADO POR ESTES ADITIVOS. UM OUTRO ASPECTO DA PRESENTE INVENÇÃO REFERE-SE A SUBSTRATOS CELULÓSICOS PARA APLICAÇÃO DAS FORMULAÇÕES À BASE DE HIDROCLORETO DE BETAÍNA.
