Cov kws tshawb fawb Fab Kis tau thov kom muaj cov khoom siv ua haujlwm tsis zoo, npaj los ntawm cov chaw ua liaj ua teb khib nyiab kas fes (SCG) thiab kaolin, los daws ob qhov tshwm sim muaj kuab paug hauv dej: recalcitrant anionic indigo dye thiab cationic metformin. Cov membrane no ua ke nrog sieving thiab adsorption functions, ua tiav cov nqi qis -cov nqi, kev lim dej kom ruaj khov. Qhov no muab txoj hauv kev tshiab rau kev lag luam thiab kev ua liaj ua teb cov dej khib nyiab thiab kev siv cov khoom pov tseg, ua raws li cov kev xav tau ntawm kev lag luam ncig thiab kev tswj hwm dej ib puag ncig.
Pom qhov kev txhim kho muaj peev xwm ntawm ceramic membrane dej kho, ① pobzeb manufacturers yuav tsim cov khoom siv ceramic; ② alumina thiab cov khoom siv refractory manufacturers tseem yuav tsim cov khoom siv ceramics; ③ ceramic hmoov thermal conductivity tuam txhab tseem yuav tsim cov khoom siv ceramic (tag nrho nrog cov nqi zoo)... yav tom ntej, cov neeg ua liaj ua teb puas siv cov khoom pov tseg ua liaj ua teb los tsim cov khoom siv ceramic? -Qhov ntau qhov zoo siab!
Txoj kev tshawb no siv kas fes hauv av los ua qhov pore- ua tus neeg sawv cev thiab qhov chaw ua haujlwm ua ntej los npaj cov pav ca- phaj ceramic membranes los ntawm kev nias qhuav thiab segmented sintering. Tus nqi ntawm kas fes av ntxiv (5-15 wt%) thiab sintering kub (600-900 degree) tau kho kom zoo siv cov txheej txheem teb saum npoo (CCD). Lub membrane lub crystal theem, morphology, porosity, nto nqi, thiab mechanical zog tau systematically yam ntxwv. Tuag- kawg pom, tshuaj tiv thaiv fouling, thiab kev rov tsim dua tshiab tau ua kom pom cov txheej txheem xaiv tshem tawm rau ob lub pa phem.
Cov txiaj ntsig tau pom tias 770℃, 15 wt% SCG membrane ua tiav 99% kev tsis lees paub tus nqi rau indigo dye nrog flux ntawm 67.6 LMH / Bar, feem ntau yog vim electrostatic repulsion thiab sieving. Lub 900℃, 15 wt% SCG membrane ua tiav 91% kev tshem tawm tus nqi rau metformin nrog flux ntawm 103 LMH / Bar, feem ntau yog vim electrostatic attraction thiab hydrogen bonding. Dye contamination yog thim rov qab (flux rov qab 94.6%), thaum cov tshuaj sib kis tsis tau ib nrab (79.8%). Cov membrane no muaj qhov zoo hauv kev kho dej khib nyiab, sib txuas ua haujlwm siab, kev lag luam, thiab kev tsim dua tshiab.
Tsab ntawv xov xwm hais tias feem ntau cov organic teeb meem adsorbed rau ntawm daim nyias nyias no tuaj yeem desorbed, tsuas yog ib qho me me ntawm - cov tshuaj molecule uas nthuav tawm cov adsorption irreversible; dye-raws li cov organic teeb meem yuav luag tag nrho desorbed thiab regenerated.
