Title (EN) POROUS INORGANIC MEMBRANES
(FR) MEMBRANES POREUSES NON ORGANIQUES
Abstract:
(EN) A composite membrane for microfiltration comprises a woven metal mesh support and films bridging the interstices comprising inorganic particles, e.g. zirconia, bonded together by 1 - 25 % of an inorganic adhesive. Group IV metal e.g. Si or Zr phosphate adhesives are preferred. Low temperature film formation without sintering permits the use of non-refractory metal supports.
(FR) Membrane composite de microfiltrage comprenant un support tissé en maille métallique et des films reliant des interstices comprenant des particules non organiques, par exemple du zircone, agglomérées par 1 - 25 % d'un adhésif non organique. Les adhésifs métalliques du groupe IV, par exemple les phosphates de Si ou Zr, sont favorisés. La formation du film à basse température sans agglomération permet l'utilisation de supports métalliques non-réfractaires.
