Abstract
"SóIS à BASE DE SìLICA E SUA PRODUçãO E USO" A presente invenção refere-se a um processo para produzir um sol aquoso à base de sílica, cujo processo compreende: (a) prover uma resina catiónica trocadora de íons, tendo pelo menos parte de sua capacidade de troca de íons na forma de hidrogênio; (b) colocar a dita resina trocadora de íons em contato com um silicato aquoso de metal alcalino, de modo a formar uma pasta fluida aquosa; (c) agitar a dita pasta fluida aquosa até que o pH da fase aquosa se situe na faixa de 5,0 a 11,5; e/ou, de forma alternativa, agitar a dita pasta fluida aquosa de modo a permitir a agregação de partícula ou formação de microgel, correspondendo a um valor de S de até 45% e obter um pE da fase aquosa de pelo menos 5,0; (d) ajustar o pH da dita fase aquosa para um valor acima de 9,0, usando um ou mais materiais que compreendem pelo menos um composto de alumínio; e (e) separar a dita resina trocadora de íons da fase aquosa, após a etapa (c) ou após a etapa (d) A invenção também se refere a um sol à base de sílica, apresentando um valor de S dentro da faixa de 15 a 25%, proporção molar de Si:Al na faixa de 20:1 a 50:1, proporção molar de Si:X, onde X = metal alcalino, na faixa de 5:1 a 17:1, teor de SiO2 de pelo menos 5% em peso e contendo partículas à base de sílica apresentando uma área superficial específica de pelo menos 300 m²/g. A invenção se refere ainda a um processo para a produção de papel, cujo processo compreende: (i) provisão de urna suspensão aquosa compreendendo fibras celulósicas; (ii)adição à suspensão aquosa de um ou mais agentes auxiliares de drenagem e retenção compreendendo um sol à base de sílica de acordo com a invenção; e (iii) desidratação da suspensão obtida para proporcionar uma folha ou tecido de papel.
