Filtres en mousse c\u00e9ramique<\/a> Ils pr\u00e9sentent la m\u00eame forme intrins\u00e8que que leur mousse de polyester \u00e0 cellules ouvertes de base. Ils sont tr\u00e8s efficaces, poss\u00e8dent une structure \u00e0 cellules ouvertes de type maill\u00e9, pr\u00e9sentent une porosit\u00e9 tr\u00e8s \u00e9lev\u00e9e \u2013 sup\u00e9rieure \u00e0 90% \u2013 ainsi qu\u2019une surface sp\u00e9cifique tr\u00e8s importante permettant de pi\u00e9ger les inclusions. Le filtre en mousse c\u00e9ramique est fabriqu\u00e9 en impr\u00e9gnant le support en mousse de base d\u2019une suspension c\u00e9ramique, puis en le cuisant \u00e0 tr\u00e8s haute temp\u00e9rature. Au cours de ce processus, le support en mousse de base se d\u00e9compose, tandis que la structure squelettique c\u00e9ramique subsiste. Dans ces filtres, le m\u00e9tal en fusion suit un parcours sinueux qui permet d\u2019\u00e9liminer les tr\u00e8s petites inclusions gr\u00e2ce \u00e0 leur attraction et \u00e0 leur adsorption \u00e0 la surface des pores c\u00e9ramiques internes.<\/p>\n![\"Filtre](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2021\/10\/Ceramic-Foam-Filter-for-Metal-Casting.jpg\")

Les filtres en mousse c\u00e9ramique sont utilis\u00e9s pour filtrer les m\u00e9taux en fusion, tels que l'aluminium, la fonte, le cuivre, l'acier et leurs alliages. Ces m\u00e9taux \u00e0 l'\u00e9tat fondu comprennent des mat\u00e9riaux m\u00e9talliques et non m\u00e9talliques. Face \u00e0 la demande croissante de produits en aluminium de haute qualit\u00e9, la filtration par CFF s'est av\u00e9r\u00e9e \u00eatre une m\u00e9thode optimale pour am\u00e9liorer la qualit\u00e9 du m\u00e9tal. Les filtres en mousse c\u00e9ramique offrent une m\u00e9thode simple, fiable et \u00e9conomique pour \u00e9liminer les inclusions. La filtration par CFF vient compl\u00e9ter les traitements m\u00e9tallurgiques effectu\u00e9s dans le four, tels que la fluxage et le d\u00e9gazage, ou la filtration en ligne.<\/p>\n
Le filtre en mousse c\u00e9ramique est muni d'un joint sur les bords afin de faciliter son installation dans le bo\u00eetier de filtre et de garantir qu'aucun m\u00e9tal ne contourne le filtre. Diff\u00e9rents types de joints sont disponibles : joints en fibre et joints expansibles. Vous pouvez \u00e9galement opter pour des filtres en mousse c\u00e9ramique sans joint.<\/p>","protected":false},"excerpt":{"rendered":"
