Abstract
"EQUIPAMENTO PARA A PREPARAçãO DE SOLUçãO AQUOSA ALCALINA DE HIDROSSULFITO DE SóDIO E USO DE UM EQUIPAMENTO". A presente invenção se refere a um equipamento para a preparação de solução alcalina de hidrossulfito de sódio utilizada para o tingimento de material têxtil celulósico com corantes a tina. O equipamento, de acordo com a presente invenção, compreende um vaso fechado com paredes isoladas termicamente, no interior do qual se dispõem pelo menos um agitador e pelo menos um trocador de calor, além de meios para manter uma atmosfera positiva e inerte dentro do dito vaso fechado e meios para a transferência da solução contida no dito vaso fechado. O equipamento é vantajosamente empregado para a preparação de solução de de corante a tina como, por exemplo, o corante índigo blue, também conhecido como Vat Blue 1 e identificado no Color lndex com o número 73.000, através de redução química na presença de um agente alcalino, por exemplo o hidróxido de sódio, e de um agente redutor, por exemplo o hidrossulfito de sódio, obtendo-se o índigo blue reduzido, também conhecido como Vat Blue 1 Reduced.
