Abstract
o presente pedido refere-se à caracterização do produto nomeado de gelpre, o qual constitui sílica gel e a seu processo de produção e extração a partir do uso de resíduos da produção de silício metálico. a sílica gel obtida tem a finalidade de ser aplicada como adição em modificador estrutural e mecânico de material de base cimentícia ou base não cimentícia. assim, pode ser utilizado em pastas, argamassas e concretos em substituição parcial ao cimento portland e a outras adições minerais já utilizadas com vistas a mudanças de microestrutura e comportamento mecânico, aumentando a durabilidade e o desempenho. além disso, pode ser utilizado como absorvedores de umidade, em biossensores, em tintas e vernizes, epóxis, pigmentos anticorrosivos, aditivos para materiais plásticos e indústrias de cosméticos. ao mesmo tempo, o produto novo proposto nomeado de gelpre usa resíduos não utilizáveis até o momento e, como reduz o consumo de cimento em matrizes cimentícias, pode minimizar a emissão de co2. a presente invenção situa-se no campo de engenharia e química.The present application refers to the characterization of the product named gelpre, which constitutes silica gel and its process of production and extraction from the use of residues from the production of metallic silicon. the silica gel obtained has the purpose of being applied as an addition in structural and mechanical modifier of cement-based or non-cement-based material. thus, it can be used in pastes, mortars and concretes in partial replacement of portland cement and other mineral additions already used with a view to changes in microstructure and mechanical behavior, increasing durability and performance. in addition, it can be used as moisture absorbers, in biosensors, in paints and varnishes, epoxies, anticorrosive pigments, additives for plastic materials and cosmetics industries. at the same time, the proposed new product named gelpre uses waste that has not been used so far and, as it reduces the consumption of cement in cementitious matrices, it can minimize the emission of co2. the present invention is in the field of engineering and chemistry.
