Abstract

"PIGMENTO DE CAULIM DE ALTA PERFORMANCE, TINTA DE REVESTIMENTO EM PAPEL FORMADA POR PIGMENTO DE CAULIM DE ALTA PERFORMANCE E MéTODO PARA PRODUZIR PIGMENTO DE CAULIM DE ALTA PERFORMANCE". Onde o pigmento de caulim apresenta simultaneamente propriedades óticas e reológicas melhoradas obtidas por meio de um controle rigoroso do tamanho e formato das partículas, bem como da distribuição do tamanho e formato das partículas; o dito pigmento de caulim apresenta as características de alvura ISO maior do que 88,5; distribuição granulométrica com no mínimo 94% em massa menor que 2 <109>m e máxima de 25% em massa menor que 0,2 <109>m e viscosidade Hércules em 1100 rpm menor que 18 dinas em polpas com concentração de sólidos de 70 a 75 % de sólidos; e ainda um método que envolve as etapas de beneficiamento do caulim grosso, as quais são compreendidas por dispersão, desareiamento para retirada da areia, centrifugação para descarte da fração de grossos e retirada das impurezas via processos convencionais como separação magnética, flotação e lixiviação química; sendo que o dito método ainda envolve as etapas de beneficiamento do caulim fino, as quais são compreendidas por dispersão, desareiamento para retirada da areia, centrifugação para descarte da fração de grossos e retirada das impurezas via processos convencionais como separação magnética, floculação e lixiviação química; sendo que para o beneficiamento do caulim grosso na etapa de centrifugação obtém-se uma fração fina caracterizada por uma distribuição granulamétrica estreita com no mínimo 94% em massa menor que 2 <109>m e máximo 18 % em massa menor que 0,2 <109>m; enquanto que para o beneficiamento do caulim fino na etapa de centrifugação obtém-se uma fração fina caracterizada por uma distribuição granulométrica com no mínimo 90 % em massa menor que 0,5 gm e no mínimo 50 % em massa menor que 0,2 <109>m.
