As cer\u00e2micas espumadas s\u00e3o produtos cer\u00e2micos porosos com porosidade de 70% a 90% e densidade aparente de apenas 0,30-0,6 g\/cm\u00b3. Possuem uma estrutura de rede tridimensional e uma estrutura de poros interpenetrantes.<\/p>\n

Al\u00e9m das propriedades das cer\u00e2micas em geral, como resist\u00eancia a altas temperaturas e resist\u00eancia \u00e0 corros\u00e3o, as cer\u00e2micas espumadas tamb\u00e9m apresentam caracter\u00edsticas como baixa densidade, alta porosidade, grande \u00e1rea superficial espec\u00edfica e forte autointerfer\u00eancia com fluidos.<\/p>\n

Os produtos cer\u00e2micos de espuma podem, de modo geral, ser divididos em materiais cer\u00e2micos de c\u00e9lula aberta (em forma de rede) e materiais cer\u00e2micos de c\u00e9lula fechada, dependendo da presen\u00e7a ou n\u00e3o de paredes s\u00f3lidas em cada poro.<\/p>\n

Se os s\u00f3lidos que formam a espuma estiverem presentes apenas nas bordas dos poros, o material \u00e9 denominado cer\u00e2mica de c\u00e9lula aberta, e os poros est\u00e3o interconectados.<\/p>\n

Se houver paredes s\u00f3lidas, a espuma \u00e9 denominada material cer\u00e2mico de c\u00e9lula fechada, no qual os poros est\u00e3o separados uns dos outros por uma matriz cer\u00e2mica cont\u00ednua.<\/p>\n

Os campos de aplica\u00e7\u00e3o da cer\u00e2mica de espuma abrangem desde a ind\u00fastria metal\u00fargica at\u00e9 a ind\u00fastria qu\u00edmica, passando pela prote\u00e7\u00e3o ambiental, economia de energia etc.; e, do ponto de vista t\u00e9cnico, v\u00e3o desde o desenvolvimento da filtragem de metal fundido at\u00e9 a filtragem para refino de ligas de alum\u00ednio e de a\u00e7o fundido em altas temperaturas.<\/p>\n

No entanto, devido \u00e0s limita\u00e7\u00f5es econ\u00f4micas e t\u00e9cnicas, a aplica\u00e7\u00e3o da tecnologia de filtros de espuma cer\u00e2mica na ind\u00fastria metal\u00fargica de fundi\u00e7\u00e3o est\u00e1 apenas come\u00e7ando.<\/p>\n

\u00c0 medida que aumentam os requisitos de pureza e desempenho dos produtos met\u00e1licos, filtra\u00e7\u00e3o por cer\u00e2mica espumosa<\/a> A tecnologia e a qualidade dos produtos est\u00e3o se tornando cada vez mais importantes.<\/p>\n

\"Filtro<\/p>\n

Os filtros de espuma cer\u00e2mica de alumina da AdTech para fundi\u00e7\u00e3o s\u00e3o comercializados em todo o mundo para a purifica\u00e7\u00e3o do alum\u00ednio fundido. A AdTech atua no setor de fundi\u00e7\u00e3o de ligas de alum\u00ednio, oferecendo solu\u00e7\u00f5es para sistemas de filtragem de alum\u00ednio fundido, sistemas de fundi\u00e7\u00e3o com topo quente, dicas para lan\u00e7adores<\/a>, etc.<\/p>\n

Nossos filtros de espuma cer\u00e2mica s\u00e3o capazes de purificar o alum\u00ednio e s\u00e3o utilizados na fundi\u00e7\u00e3o de tarugos de alum\u00ednio, na fundi\u00e7\u00e3o de folhas de alum\u00ednio, na fundi\u00e7\u00e3o de placas, etc. O filtro de alumina para fundi\u00e7\u00e3o consegue remover e absorver com efic\u00e1cia diversas impurezas presentes no alum\u00ednio fundido, melhorando a qualidade da superf\u00edcie, o desempenho do produto e a efic\u00e1cia da microestrutura. \u00c9 utilizado principalmente na fundi\u00e7\u00e3o de precis\u00e3o de ligas de alum\u00ednio.<\/p>","protected":false},"excerpt":{"rendered":"
