O filtro de cer\u00e2mica espumosa destina-se principalmente \u00e0 filtragem de alum\u00ednio e ligas de alum\u00ednio em oficinas de fundi\u00e7\u00e3o. Com excelente resist\u00eancia aos efeitos agressivos e \u00e0 corros\u00e3o do alum\u00ednio fundido, o filtro \u00e9 capaz de remover eficazmente as impurezas, reduzir a quantidade de g\u00e1s retido e garantir um fluxo laminar, tornando o metal filtrado significativamente mais puro. Um metal mais puro resulta em pe\u00e7as fundidas de maior qualidade, menor quantidade de rejeitos e menos defeitos por inclus\u00f5es, o que contribui para o aumento do lucro l\u00edquido.<\/p>\n

Os metais e os produtos met\u00e1licos t\u00eam uma liga\u00e7\u00e3o especial com a civiliza\u00e7\u00e3o humana. Eles s\u00e3o considerados um dos primeiros materiais dominados pelo homem. No entanto, nem todos os metais s\u00e3o muito est\u00e1veis em sua forma bruta. Essa forma dos metais pode n\u00e3o apresentar as propriedades met\u00e1licas ideais e, por isso, requer purifica\u00e7\u00e3o. O processo de purifica\u00e7\u00e3o do metal fundido requer o uso de um filtro de cer\u00e2mica espumosa, que garante a remo\u00e7\u00e3o de todas as impurezas da solu\u00e7\u00e3o met\u00e1lica. Assim que esse processo \u00e9 conclu\u00eddo, o metal est\u00e1 pronto para ser utilizado em diversas \u00e1reas de aplica\u00e7\u00e3o por meio de diferentes processos.<\/p>\n

De acordo com os padr\u00f5es geralmente aceitos no setor, o filtro de cer\u00e2mica espumosa possui v\u00e1rias propriedades essenciais que garantem a f\u00e1cil limpeza do metal fundido. Esses componentes porosos desempenham um papel muito importante em todo esse processo; por isso, devem apresentar propriedades padronizadas.<\/p>\n

Principais propriedades do filtro de espuma cer\u00e2mica<\/p>\n

As temperaturas naturais de fus\u00e3o de diversos elementos met\u00e1licos s\u00e3o muito altas. A faixa de temperaturas de fus\u00e3o dos metais pode variar, mas geralmente fica entre algumas centenas e mais de mil graus Celsius. Por isso, \u00e9 extremamente necess\u00e1rio que os filtros de material cer\u00e2mico espumado possuam determinadas propriedades. Aqui est\u00e3o algumas propriedades \u00fateis<\/p>\n

A porosidade \u00e9 a porcentagem do espa\u00e7o poroso do filtro. Essa propriedade \u00e9 muito importante durante a opera\u00e7\u00e3o, pois um filtro com porosidade significativamente maior ou menor pode dificultar o processo. Portanto, recomenda-se que a porosidade seja ideal para o tipo de metal fundido utilizado.<\/p>\n

A quantidade de mat\u00e9ria-prima utilizada no processo de purifica\u00e7\u00e3o \u00e9 muito grande, uma vez que realizar esse processo em pequenas quantidades n\u00e3o \u00e9 uma solu\u00e7\u00e3o economicamente vi\u00e1vel. Por isso, uma grande quantidade de solu\u00e7\u00e3o met\u00e1lica \u00e9 derramada sobre esses filtros, e, portanto, eles devem apresentar alta resist\u00eancia \u00e0 compress\u00e3o para suportar o trabalho sem sofrer danos.<\/p>","protected":false},"excerpt":{"rendered":"
