materiais cer\u00e2micos espumosos<\/a> surgiu na d\u00e9cada de 1970 e \u00e9 um material poroso com caracter\u00edsticas de resist\u00eancia a altas temperaturas.
\nO tamanho de seus poros varia de nan\u00f4metros a micr\u00f4metros. Possui um corpo cer\u00e2mico poroso de alta porosidade com uma estrutura espacial tridimensional em forma de grade. A porosidade est\u00e1 entre 20% e 95%. Sua forma se assemelha \u00e0 de uma espuma temperada ou porcelana. A esponja pode ser utilizada em temperaturas que variam da temperatura ambiente at\u00e9 1.600 \u2103.
\nDesde que os Estados Unidos inventaram, em 1978, o uso de pastas cer\u00e2micas, como a alumina e o caulim, para desenvolver com sucesso cer\u00e2micas espumadas para fundi\u00e7\u00e3o de ligas de alum\u00ednio e filtragem, a Gr\u00e3-Bretanha, o Jap\u00e3o, a Alemanha, a Su\u00ed\u00e7a e outros pa\u00edses t\u00eam competido nessa \u00e1rea de pesquisa.
\nO processo de produ\u00e7\u00e3o da Asian Foundry Filter est\u00e1 se tornando cada vez mais avan\u00e7ado, e os equipamentos t\u00e9cnicos est\u00e3o se tornando cada vez mais mecanizados e automatizados. De acordo com as diferentes finalidades de aplica\u00e7\u00e3o, foi desenvolvida uma variedade de materiais para filtros de cer\u00e2mica espumosa, adequados para diversas finalidades.
\nComo A1203, ZrO\u2082, SiC, nitreto de sil\u00edcio, boreto e outras cer\u00e2micas espumadas para altas temperaturas; al\u00e9m disso, algumas tamb\u00e9m incorporam determinados minerais, como mulita, Dong Qingshi, cinzas volantes, cinzas de carv\u00e3o etc., e os produtos foram padronizados e produzidos em s\u00e9rie, dando origem a um novo setor.<\/p>\n![\"Filtro](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2020\/07\/Asian-Foundry-Filter.jpg\")
<\/p>\n
A China \u00e9 um grande produtor de produtos de alum\u00ednio, e sua produ\u00e7\u00e3o sempre foi a maior do mundo, mas concentra-se principalmente em produtos de baixo padr\u00e3o. Com a expans\u00e3o cont\u00ednua da demanda do mercado, os produtos de alum\u00ednio devem evoluir para o segmento de alto padr\u00e3o. O uso de placas filtrantes de cer\u00e2mica espumada pode melhorar a qualidade dos produtos de alum\u00ednio e elevar os padr\u00f5es dos produtos para atender \u00e0s exig\u00eancias do mercado de alta qualidade. Portanto, a demanda por placas filtrantes.<\/p>\n
\u00c9 importante ressaltar que \u00e9 necess\u00e1rio evitar a polui\u00e7\u00e3o secund\u00e1ria da massa fundida, que pode ocorrer durante o processo de solidifica\u00e7\u00e3o e conforma\u00e7\u00e3o, ap\u00f3s a massa fundida de alum\u00ednio sair da caixa de filtragem.
\nNesse processo, utilize alum\u00ednio antiaderente de alta resist\u00eancia e longa vida \u00fatil, al\u00e9m de uma calha de sinteriza\u00e7\u00e3o, caixa frontal, placa de distribui\u00e7\u00e3o e tampa t\u00e9rmica de cer\u00e2mica de s\u00edlica fundida com bom isolamento t\u00e9rmico, e realize a desumidifica\u00e7\u00e3o e a limpeza em tempo h\u00e1bil para eliminar poss\u00edveis fontes de contamina\u00e7\u00e3o.<\/p>\n
Os filtros Asian Foundry constituem a \u00faltima etapa do processo de purifica\u00e7\u00e3o do alum\u00ednio fundido. Eles s\u00e3o essenciais para garantir a limpeza do alum\u00ednio fundido.<\/p>","protected":false},"excerpt":{"rendered":"
