Les plaques filtrantes en c\u00e9ramique permettent de filtrer efficacement les inclusions solides non m\u00e9talliques pr\u00e9sentes dans les coul\u00e9es d'aluminium et d'alliages d'aluminium. Elles sont fabriqu\u00e9es \u00e0 partir d'\u00e9ponges en mousse pr\u00e9sentant une structure \u00e0 cellules ouvertes tr\u00e8s d\u00e9velopp\u00e9e et de mat\u00e9riaux c\u00e9ramiques de haute puret\u00e9, ce qui permet d'obtenir des plaques filtrantes en mousse moul\u00e9e dont le taux de porosit\u00e9 est soumis \u00e0 un contr\u00f4le qualit\u00e9 rigoureux. Elles b\u00e9n\u00e9ficient d'un frittage suffisant et d'une bonne r\u00e9sistance \u00e0 la flexion, garantissant ainsi une filtration hautement efficace. L'entreprise propose diff\u00e9rentes tailles de pores, toutes disponibles en plusieurs dimensions.<\/p>\n

Plaques filtrantes en mousse c\u00e9ramique<\/a> sont largement utilis\u00e9s pour la filtration et la purification de divers bains d'aluminium et d'alliages d'aluminium, notamment dans le cadre de la coul\u00e9e continue, de la coul\u00e9e semi-continue, de la coul\u00e9e par gravit\u00e9 et de la coul\u00e9e \u00e0 basse pression. Outre les sp\u00e9cifications g\u00e9n\u00e9rales, ils peuvent \u00eatre con\u00e7us en fonction des besoins des clients.<\/p>\n

La plaque filtrante en c\u00e9ramique pr\u00e9sente une structure r\u00e9ticulaire tridimensionnelle, ce qui explique son utilisation r\u00e9pandue dans le domaine de la filtration des masses fondues d'aluminium et d'alliages d'aluminium.
\nBien qu'il fasse l'objet d'efforts constants pour \u00eatre utilis\u00e9 dans les domaines de la protection de l'environnement, de la chimie, de l'\u00e9nergie, du p\u00e9trole, de la bioc\u00e9ramique et des supports de catalyseurs, son utilisation reste limit\u00e9e dans de nombreux domaines en raison de sa faible r\u00e9sistance, de sa tendance \u00e0 former facilement des scories et de sa faible pr\u00e9cision dimensionnelle.<\/p>\n

\u00c0 l'heure actuelle, les fabricants de filtres en mousse c\u00e9ramique d'alumine continuent de se concentrer sur la filtration de l'aluminium et des alliages d'aluminium \u00e0 l'\u00e9tat fondu, et n'ont pas encore r\u00e9ussi \u00e0 mettre au point des produits similaires susceptibles de remplacer ces applications sur le march\u00e9.<\/p>\n

\"Filtre<\/p>\n

Par cons\u00e9quent, avec les progr\u00e8s r\u00e9alis\u00e9s dans le domaine de l'usinage de pr\u00e9cision de l'aluminium et des alliages d'aluminium, les c\u00e9ramiques \u00e0 base de mousse d'alumine continueront \u00e0 se d\u00e9velopper et \u00e0 trouver de nouvelles applications.<\/p>\n

Il existe diff\u00e9rentes m\u00e9thodes de fabrication des plaques filtrantes en c\u00e9ramique, telles que le proc\u00e9d\u00e9 de moussage, le proc\u00e9d\u00e9 d'impr\u00e9gnation de mousse organique, le proc\u00e9d\u00e9 sol-gel, etc.<\/p>\n

Parmi ceux-ci, le proc\u00e9d\u00e9 d'impr\u00e9gnation de mousse organique pr\u00e9sente les avantages suivants : un \u00e9quipement r\u00e9duit, un faible co\u00fbt de fabrication et un proc\u00e9d\u00e9 simple ; il est largement utilis\u00e9 par les fabricants de mousse c\u00e9ramique.<\/p>\n

Le filtre en mousse c\u00e9ramique est un corps c\u00e9ramique poreux dot\u00e9 d'une structure r\u00e9ticulaire tridimensionnelle. Il est constitu\u00e9 d'une \u00e9ponge de polyur\u00e9thane poreuse servant de squelette, pr\u00e9par\u00e9e par encollement, s\u00e9chage et cuisson. Le pr\u00e9curseur organique de la structure r\u00e9ticulaire tridimensionnelle est \u00e9limin\u00e9 afin de former une porosit\u00e9 ouverte. Une structure poreuse en forme de treillis pr\u00e9sentant une surface sp\u00e9cifique \u00e9lev\u00e9e et une faible perte de charge.<\/p>","protected":false},"excerpt":{"rendered":"
