Abstract

Patente de Invenção: <B>"PROCESSO PARA PREVENIR A COLAGEM DE CHAPAS METáLICAS, QUANDO DE UM TRATAMENTO TéRMICO"<D>. Processo que compreende uma etapa de tratamento térmico, propriamente falando, durante a qual essas chapas ficam em contato sobre uma parte de sua superfície (isto é, são, por exemplo, bobinadas ou em feixes comprimidos) e uma etapa de tratamento prévio dessas superfícies com o auxílio de uma solução aquosa ou hidroalcoólica, na qual se introduz um produto orgânico de tipo silano. Esse tratamento permite evitar a colagem das chapas; ele é particularmente eficaz e não necessita de ativação prévia da superfície.
