Abstract

MéTODO DE PREPARAçãO DE UM MATERIAL DE POLPA ALVEJADA QUE TEM UM BRILHO INTENSIFICADO E UMA MAIOR RESISTêNCIA AO AMARELECIMENTO TéRMICO, MéTODO PARA IMPEDIR A PERDA DO BRILHO E O AMARELECIMENTO DE UM MATERIAL DE POLPA ALVEJADA DURANTE A ARMAZENAGEM, MATERIAL DE POLPA ALVEJADA QUE TEM BRILHO INTENSIFICADO E UMA MAIOR RESISTêNCIA AO AMARELECIMENTO TéRMICO, MéTODO DE OBTENçãO DE UM PRODUTO DE PAPEL QUE TEM BRILHO INTENSIFICADO E UMA MAIOR RESISTêNCIA AO AMARELECIMENTO TéRMICO, PRODUTO DE PAPEL, MATERIAL DE POLPA ALVEJADA E FORMULAçãO. Composições e processos que preservam e intensificam o brilho e melhoram a cor da polpa ou do papel quando aplicados durante estágios diferentes do processo de fabricação de papel são identificados. A composição e o método mantêm e/ou intensificam o brilho, impedem o amarelecimento, e intensificam o desempenho dos produtos de papel. Utilizados em combinação com clareadores ópticos e/ou quelantes, os agentes descritos produzem um efeito sinergístico não identificado anteriormente no processo de papel.
