Title (EN) CERAMIC FOAM FILTER PRODUCTION
(FR) FABRICATION D'UN FILTRE EN MOUSSE CERAMIQUE
Abstract:
(EN) The invention is about the production of ceramic foam filters. In the invention foam filters are produced: Case 1. From an open cell flexible or non flexible foam material inserted in a mold on a centrifugal casting machine where ceramic slip enters the mold under centrifugal force. Case 2a. From partly expanded spherical polystyrene beads packed in a mold on a centrifugal casting machine where ceramic slip enters the mold under centrifugal force. Case 2b. From partly expanded spherical polystyrene beads packed in a stationary or vibrating mold where ceramic slip enters the mold from a reservoir at the top. In all cases the end of the molds where aqueous part of the ceramic slurry leaves are closed either by a filter paper or by a gypsum plate.
(FR) L'invention concerne la fabrication de filtres en mousse céramique, ce qui consiste à: (cas N°1) introduire dans un moule de machine centrifuge à mouler un matériau de mousse à cellules ouvertes, souple ou non souple, la barbotine de céramique pénétrant dans le moule sous l'effet de la force centrifuge; (cas N°2) introduire dans un moule de machine centrifuge à mouler des granules sphériques de polystyrène partiellement expansé, la barbotine de céramique pénétrant dans le moule sous l'effet de la force centrifuge; (cas N°3) introduire dans un moule fixe ou vibrant des granules sphériques de polystyrène partiellement expansé, la barbotine de céramique étant introduite dans le moule depuis un réservoir placé au sommet. Dans tous ces cas, l'extrémité des moules, au niveau de laquelle la partie aqueuse de la barbotine de céramique est évacuée, est fermée, soit par un filtre en papier, soit par une plaque de gypse.
