Atualmente, a tecnologia de filtragem que utiliza filtros de espuma cer\u00e2mica \u00e9 reconhecida como um m\u00e9todo eficaz para reduzir as inclus\u00f5es no metal fundido durante a fundi\u00e7\u00e3o de pe\u00e7as met\u00e1licas.<\/p>\n

Desde componentes essenciais nas ind\u00fastrias aeron\u00e1utica e automotiva at\u00e9 aplica\u00e7\u00f5es dom\u00e9sticas, 90% dos produtos e equipamentos fabricados cont\u00eam pe\u00e7as fundidas de metal. No entanto, o metal fundido efetivamente utilizado para produzir pe\u00e7as fundidas geralmente cont\u00e9m impurezas e inclus\u00f5es que s\u00e3o prejudiciais ao produto final fundido.<\/p>\n

Com o objetivo de melhorar a efici\u00eancia da filtragem de metal fundido, especialmente no caso do filtro de espuma cer\u00e2mica para ligas \u00e0 base de alum\u00ednio, a AdTech oferece um filtro de espuma cer\u00e2mica de alumina.<\/p>\n

O filtro de espuma cer\u00e2mica \u00e9 produzido por meio da impregna\u00e7\u00e3o da espuma de poliuretano com uma pasta cer\u00e2mica, seguida de secagem, cozimento e, por fim, queima da espuma em um forno. Ele apresenta excelente resist\u00eancia ao choque t\u00e9rmico, resist\u00eancia \u00e0 compress\u00e3o suficiente, densidade aceit\u00e1vel e permeabilidade.<\/p>\n

\"Fabricante<\/p>\n

AdTech especialmente projetada Filtros de espuma cer\u00e2mica<\/a> s\u00e3o fabricados com a mat\u00e9ria-prima b\u00e1sica \u00f3xido de alum\u00ednio. S\u00e3o produzidos com porosidades que variam de 10 a 60 poros por polegada (PPI). Al\u00e9m disso, os conjuntos combinados s\u00e3o fabricados com 20 a 30 PPI, sendo poss\u00edveis outras op\u00e7\u00f5es. S\u00e3o fabricados filtros de diferentes tamanhos e sob medida, de acordo com as especifica\u00e7\u00f5es.<\/p>\n

Desde que a tecnologia de filtragem com filtros de espuma cer\u00e2mica passou a ser utilizada na ind\u00fastria do alum\u00ednio, ela se tornou o material de filtragem mais amplamente utilizado e preferido na ind\u00fastria mundial do alum\u00ednio. A variedade existente de tamanhos e porosidades dos filtros \u00e9 capaz de atender aos requisitos de fundi\u00e7\u00e3o de todas as ligas de alum\u00ednio. Sua utiliza\u00e7\u00e3o e manuten\u00e7\u00e3o s\u00e3o simples e eficazes, com baixo custo, e constituem um m\u00e9todo eficaz para a remo\u00e7\u00e3o de inclus\u00f5es n\u00e3o met\u00e1licas do alum\u00ednio fundido.<\/p>\n

Quando o alum\u00ednio fundido passa por esses caminhos sinuosos, semelhantes a um labirinto, as inclus\u00f5es s\u00e3o adsorvidas nos poros do filtro. No entanto, \u00e9 importante que a vaz\u00e3o do metal esteja dentro da faixa ideal e que a \u00e1rea total efetiva de filtra\u00e7\u00e3o possa ser totalmente utilizada. Se o material do filtro for irregular e houver orif\u00edcios danificados, a vaz\u00e3o do metal atrav\u00e9s do filtro aumentar\u00e1, o que impedir\u00e1 que as inclus\u00f5es sejam completamente retidas ou far\u00e1 com que as impurezas retidas sejam levadas pela corrente.<\/p>","protected":false},"excerpt":{"rendered":"
