Njàngalem jëmmal membrane seramik aluminium

Membrane ceramic alumina, muy macceer tàqale inorganik bu am doole, ñu ngi ko sos ci gëna xéewale science macceer, chimie surface, ak xaralay tàqale, ngir am tànneef bu kawe, dundu gu yàgg, ak stabilite chimik bu baax. Njàngalem konseptioŋ bi dafa wër liñ defaree macceer bi, di saytu mikrostruktuur yi, ak ni ñuy doxalee ci kaw suuf si.

Bi njëkk mooy substrat bi ñuy jëfandikoo ngir membrane ceramic alumina dafay gëna sell Al2O3, ndax stabilite thermique bu baax (point de fusion buy tollu ci 2050 degre), doole mekanik (dëgër bu rëy ak baña yëngu), ak baña asid ci alkali ak inertness chimik. Sooy saytu anam yi sintering bi di doxee (lu melni tàngoor, jawwu ji, ak waxtu wi), di nga mëna yamale dayo pepp mi ak porosite bi, loolu mooy gëna baaxal permeabilite membrane bi ak màndarga mekanik yi. Li gëna fës ci membrane alumine bu am pore mooy lu am couche buy jàppale, couche buy jàll, ak couche bu koy tàqale. Design pore hierarchique (ak macropores ci couche biy jàppale mekanik ak micropores ci couche tàqale biy may tàqale bu baax) lu am solo la.

Ñaareel ba mooy seddaleb dayo pore yi ak màndarga yi ci kaw dañu am njeexital ci njariñu tàqale bi. Ci anam yu melni sol{1}}gel, oxidation anodik, wala synthese hydrothermal, mën nañu saytu dayo pore yi ci anam wu jaar yoon (0.01–10 μm), suko defee ñu mëna ko jëfandikoo ci mikrofiltraasioŋ, ultrafiltraasioŋ, wala sax nanofiltration. Jafe-jafe charge surface (lu melni dugal ay groupe hydroxyl wala ay groupe fonctionnel) mën na gëna yombal adsorption ion wala molecule yuñ tànn, gëna baaxal tàqale gi. Rax ci dolli, mën nañu jëfandikoo membrane alumine yu dëgër (yu amul porous wala nanoporous) ngir tàqale gaz yi wala ngir setal gaz yi ci tàngoor wu kawe, lépp di aju ci seen permeabilite bu tuuti lool ak seen tànneef bu rëy.

Fi may jeexalee mooy, sooy jëmmal membrane ceramic alumina, fàww nga bàyyi xel ci anam wi ñu koy defee, lu ci melni tàngoor wu metti, medium yuy yàq lool, wala anam yu am pressure bu yéeg. Doping (lu melni ZrO2 ak TiO2) mën na yokk màndarga mekanik yi ak deggoo gi ci yaatuwaayu tàngoor, loolu mooy yokk àppu liggéey bi. Ci gàttal, jëmmal membrane ceramic alumina mooy résultaa bi juddoo ci gëna xéewale macceer yi, jëmmal, ak fonction, di joxe pexe xarala yu wóor ngir tàqale usine yi, aar environmaa bi, ak energie.
