Abstract

um processo para a produção de um substrato compreendendo pigmentos de sílica que é formado sobre a superfície do substrato. a presente invenção se refere a um processo para a produção de um substrato. em concordância com a presente invenção, o processo compreende as etapas de: - provisão de um substrato compreendendo fibras celulósicas; - apicação de uma solução compreendendo silicato solúvel em água para a superfície do substrato; - tratamento do substrato de maneira que o silicato solúvel em água é polimerizado formando pigmentos de sílica sobre a superfície do substrato; e secagem do substrato. a presente invenção também se refere a um substrato produzido em concordância com o processo anteriormente descrito.A process for producing a substrate comprising silica pigments that is formed on the surface of the substrate. The present invention relates to a process for producing a substrate. In accordance with the present invention, the process comprises the steps of: providing a substrate comprising cellulosic fibers; applying a solution comprising water soluble silicate to the substrate surface; - treating the substrate so that water soluble silicate is polymerized by forming silica pigments on the substrate surface; and substrate drying. The present invention also relates to a substrate produced in accordance with the process described above.
