Abstract

"PROCESSO PARA A REGENERAçãO FUNCIONAL DA POROSIDADE DE MOLDES USADOS PARA MOLDAGEM DE OBJETOS CERâMICOS". Um processo para a regeneração funcional da porosidade dos materiais usados para fazer moldes (2), para moldagem de objetos cerâmicos, quando os poros tenham sido danificados pelo uso do molde (2), compreendendo a execução seq³encial de pelo menos duas etapas sucessivas de uma seq³ência ordenada que inclui as etapas de: eliminar a contaminação causada por substâncias orgânicas que formam o molde (2); eliminar contaminação de origem biológica a partir do molde (2); atacar as incrustações inorgânicas e eliminar as substâncias inorgânicas as quais tenham infiltrado os poros do molde (2), a etapa inicial do processo sendo pré-fixada de acordo com a natureza de um agente de contaminação pré-determinado. Uma estação implementando o processo é também uma parte integral da presente invenção.
