Abstract
AUXILIARES NãO CORROSIVOS PARA SOLDAR ALUMìNIO E/OU PARA MELHORAR LIGAS DE ALUMìNIO COM BASE EM FLUOROALUMINATOS DE METAL ALCALINO, PROCESSO PARA A PREPARAçãO DOS MESMOS, E, USO DOS AUXILIARES A invenção diz respeito a agentes auxiliares não corrosivos com base em fluoroaluminatos de alquila, para soldar alumínio e para refinar ligas de alumínio, à sua produção e a seu uso. De acordo com a invenção, os ditos agentes auxiliares não corrosivos contém metalatos. Para formar os metalatos, compostos metálicos de elementosnos 3 a 5 grupos principais da tabela periódica ou de elementos nos sub-grupos são usados na forma de sais ou de óxidos como co-reagentes. Em particular por exemplo, os haletos, nitrato, carbonatos, sulfatos, fosfatos, boratos, hexafluorossilicatos ou óxidos dos ditos compostos são usados. De acordo com a invenção, os compostos metálicos são introduzidos na mistura de reação que compreende que compreende de ácido fluorídico e/ou hidrato de alumina e/ou composto um composto alcalino. O tempo da adição do composto metálico pode ser variado de acordo com o grau desejado de funcionalização da superfície.
