Abstract

Patente de Invenção: "PRODUTOS DE CAULIM E SUA PREPARAçãO E USO NA FABRICAçãO E REVESTIMENTO DE PAPEL". A invenção refere-se a um método de preparação de uma composição para uso em composições para fabricação de ou de revestimento de pigmento de papel contendo também um a gente abrilhantador óptico (OBA) inclui as etapas de (a) preparação de uma suspensão aquosa de mineral de argila compreendendo um material em partícula de caulim; e (b) tratamento do mineral de argila através da adição de um agente de tratamento que reduz o efeito danoso dos íons de metal presentes no mineral de argila sobre a atividade do OBA, o agente de tratamento sendo substancialmente livre de cátions multivalentes e compreendendo (i) agente de complexação ou (ii) ácido de formamidina sulfínico (FAS).Invention patent: "Kaolin products and their preparation and use in the manufacture and coating of paper". The invention relates to a method of preparing a composition for use in compositions for the manufacture of or coating paper pigments also containing an optical brightener (OBA) includes the steps of (a) preparing an aqueous suspension of clay mineral comprising a kaolin particle material; and (b) treatment of the clay mineral by adding a treatment agent that reduces the harmful effect of the metal ions present in the clay mineral on the OBA activity, the treatment agent being substantially free of multivalent cations and comprising ( i) complexing agent or (ii) sulfinic formamidine acid (FAS).
