O filtro de espuma cer\u00e2mica AdTech com junta de fibra n\u00e3o s\u00f3 remove impurezas min\u00fasculas, como tamb\u00e9m absorve inclus\u00f5es na ordem dos m\u00edcrons, gra\u00e7as \u00e0s suas propriedades adsorventes. Por apresentarem excelente resist\u00eancia \u00e0 eros\u00e3o e \u00e0 corros\u00e3o causadas pelo alum\u00ednio fundido, esses filtros conseguem remover inclus\u00f5es de forma eficaz, reduzir o g\u00e1s retido e proporcionar um fluxo laminar, resultando em um metal filtrado significativamente mais limpo.<\/p>\n

Com o desenvolvimento da ci\u00eancia e da tecnologia, a produ\u00e7\u00e3o industrial tem exig\u00eancias cada vez maiores quanto \u00e0 pureza e \u00e0 qualidade do alum\u00ednio e de suas ligas. O processo tradicional de refino e desgaseifica\u00e7\u00e3o n\u00e3o consegue remover as inclus\u00f5es n\u00e3o met\u00e1licas finas e em suspens\u00e3o presentes no alum\u00ednio fundido. Metais mais puros permitem a produ\u00e7\u00e3o de pe\u00e7as fundidas de melhor qualidade, gerando menos refugo e menos defeitos por inclus\u00f5es, o que contribui para aumentar os lucros. Por isso, t\u00eam sido estudados diversos m\u00e9todos de purifica\u00e7\u00e3o. De acordo com seus diferentes mecanismos e formas, eles podem ser divididos em purifica\u00e7\u00e3o por adsor\u00e7\u00e3o, purifica\u00e7\u00e3o f\u00edsica e purifica\u00e7\u00e3o por filtra\u00e7\u00e3o.<\/p>\n

A filtragem e a purifica\u00e7\u00e3o consistem em fazer com que o metal fundido passe por um determinado meio. Esse meio ret\u00e9m as inclus\u00f5es de acordo com um determinado mecanismo, purificando assim o metal. Em 1978, os Estados Unidos desenvolveram um novo filtro-filtro de espuma cer\u00e2mica<\/a>, que oferece um filtro de alta efici\u00eancia para a produ\u00e7\u00e3o de pe\u00e7as fundidas de alum\u00ednio e \u00e9 amplamente utilizado na produ\u00e7\u00e3o de lingotes semicont\u00ednuos e pe\u00e7as fundidas moldadas.<\/p>\n

\"\"<\/p>\n

O filtro de espuma cer\u00e2mica, com junta, ajuda a fixar o filtro na caixa de filtro e garante que nenhum metal contorne o filtro. Existem diferentes tipos de juntas dispon\u00edveis, como a junta de fibra e a junta expans\u00edvel.<\/p>\n

A efici\u00eancia de filtragem est\u00e1 relacionada ao tamanho das c\u00e9lulas do filtro de espuma cer\u00e2mica. Ao controlar cuidadosamente o tamanho das c\u00e9lulas do filtro, \u00e9 poss\u00edvel obter um desempenho de filtragem mais consistente. Normalmente, a efici\u00eancia de remo\u00e7\u00e3o aumenta \u00e0 medida que o tamanho das c\u00e9lulas do filtro e a velocidade do metal no filtro diminuem.<\/p>\n

Os filtros de espuma cer\u00e2mica est\u00e3o dispon\u00edveis em todos os tamanhos comuns: 7\u2033, 9\u2033, 12\u2033, 15\u2033, 17\u2033, 20\u2033 e 23\u2033. Oferecemos toda a gama de porosidades, de PPI 10 at\u00e9 PPI 60 (PPI = poros por polegada). Tamb\u00e9m \u00e9 poss\u00edvel fabricar filtros sob medida.<\/p>","protected":false},"excerpt":{"rendered":"
