Abstract

"PROCESSO E DISPOSITIVO PARA PRODUZIR Pó DE SOLDA BRANCA" A invenção refere-se a um processo e um dispositivo para produzir pó de solda branca sem pressão, em particular para produzir partículas de metal finas exatamente esféricas que tem um tamanho de grão de 1 a 100 Ám e uma temperatura liquidus de <250°C, feitas de solda maciça usando-se as etapas de processo seguintes: a) alimentar pela força da gravidade a solda fundida em um outro recipiente para óleo ao mesmo tempo fixando-se a razão de volume de óleo para solda fundida em pelo menos 10:1; b) dispersar a solda liq³efeita pela agitação e por um cisalhamento subsequente, em etapas de cisalhamento consecutivas, de acordo com o princípio de rotor/estator a velocidades de rotação na faixa de 1500 até 5000 rpm, ao mesmo adicionando-se óleo do recipiente da etapa a) ; c) circular a mistura de solda/óleo da etapa b) pelo menos vinte vezes em um circuito contrário à direção de fluxo acima do recipiente de óleo da etapa a) e nas etapas de cisalhamento; d) transferir para fora a mistura de solda/óleo do circuito da etapa c) em um outro recipiente de óleo para separar o material dispersado pela sedimentação e retornar o óleo ao recipiente da etapa b) e/ou a; e e) extrair e alimentar o material dispersado da etapa d) para lavagem subsequente.
