Saib rov qab ntawm kev lag luam txoj kev loj hlob nyob rau hauv ib puas xyoo dhau los, cov evolution ntawm ceramic membrane cov ntaub ntawv yeej tsis yog ib tug technological gimmick, tab sis yog ib tug inevitable tshwm sim ntawm kev vam meej kev vam meej. Tsab ntawv xov xwm no taug qab cov keeb kwm kev loj hlob ntawm ceramics, dissecting lub hauv paus logic los ntawm kev tshawb fawb ntawm ntau yam ntaub ntawv, nrov ntawm alumina, kev siv ntawm domestic ntau lawm, thiab iteration rau silicon carbide, yog li tau txais kev nkag siab ntawm cov ncauj lus tseem ceeb hauv kev lag luam inorganic membrane.
I. Keeb Kwm los ntawm Kev Lag Luam Tub Rog: Thawj Kev Tshawb Fawb Yug los ntawm "Kev Sib Cai Tshwj Xeeb" (1940s)
Ceramic membrane tsis yog tsim los rau kev kho dej, tab sis ua haujlwm rau kev sib cais ntawm isotopes hauv kev lag luam nuclear. Nyob rau lub sijhawm ntawd, kev lag luam xav tau ceev ceev cov neeg nqa khoom uas muaj lub cev thiab tshuaj lom neeg ruaj khov, tsis hnov mob nrog qhov nruab nrab, muaj qhov pore me me, cov qauv ruaj khov, thiab tuaj yeem ua haujlwm tau ntev hauv cov xwm txheej hnyav. Ceramic membrane tsuas yog ua tau raws li qhov yuav tsum tau ua.
Yees duab: UF₆ (uranium hexafluoride)
Ceramic membranes tsim nyob rau theem no tsuas yog cov ntaub ntawv tshwj xeeb uas siv hauv cov chaw sim. Lawv qhov pore loj tswj tau ntxhib thiab lawv qhov kev sib cais qhov tseeb yog qhov tsawg, ua rau lawv tsis tsim nyog rau kev kho dej ua haujlwm. Txawm li cas los xij, lawv tau tso lub hauv paus rau cov yam ntxwv tseem ceeb ntawm "kev ruaj khov thiab kev tiv thaiv corrosion" hauv cov txheej txheem ceramic membrane tom ntej.
II. Qhov tshwm sim ntawm alumina ceramic membranes: daws qhov teeb meem "los ntawm 0 mus rau 1" hauv kev kho dej (1960s-1990s)
Nrog rau txoj kev loj hlob sai ntawm kev lag luam thoob ntiaj teb, qhov kev thov rau kev qhia ua kua thiab cov khoom sib cais hauv cov khoom noj thiab dej haus thiab cov tshuaj lom neeg kev lag luam tau tawg. Ib txwm phaj thiab thav duab pom thiab lim ntawv tsis meej txaus thiab yooj yim kis tau. Kev lag luam urgently xav tau ib tug reusable thiab washable inorganic lim cov ntaub ntawv, thiab ceramic ultrafiltration membranes tau tshwm sim kom tau raws li qhov xav tau no.
Tom qab kev ntsuas ntsuas tawm tsam ntau yam khoom siv tsis zoo, alumina tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev siv pej xeem kev lag luam. Txawm hais tias nws tsis yog qhov siab tshaj - ua haujlwm cov khoom siv tsis zoo, nws muaj qhov zoo hauv kev tsim khoom loj: ntau bauxite reserves, cov khoom siv qis, paub tab qis -kub sintering thev naus laus zis, qib siab ntawm standardization ntawm cov khoom tiav, sib npaug physicochemical zog nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, thiab tswj tau ntau lawm thiab txij nkawm nqi thoob plaws hauv lub neej. Nws yog cov khoom siv hauv cov khoom siv tsis zoo uas haum rau loj - nplai thoob ntiaj teb xa tawm.
Alumina ceramic membranes tau ua tiav cov kev cai tseem ceeb ntawm "kev ruaj ntseg thiab rov siv dua" hauv kev pom kev lag luam, dhau los ua thawj cov ntaub ntawv ceramic kom ua tiav daim ntawv thov kev lag luam.
III. Industrial Localization: Domestic Alumina Ceramic Membranes Achieve Independent Mass Production (Early 21st Century)
Nyob rau hauv thaum ntxov 21st caug xyoo, domestic kev thov rau industrial filtration surged. Txawm li cas los xij, alumina ceramic membranes tau ua tiav los ntawm cov neeg muag khoom txawv teb chaws, ua rau cov nqi siab thiab qeeb tom qab - kev muag khoom. Yog li ntawd, kev hloov pauv hauv tsev ntawm inorganic membranes dhau los ua qhov tsim nyog rau kev lag luam. Cov tsev tshawb fawb hauv tsev thiab cov lag luam sib koom tes ua kom tiav cov khoom lag luam ywj pheej ntawm domestically ua alumina ceramics. Kev tsim khoom hauv tsev tau txo qis cov nqi thov thiab ua tiav qhov khoob hauv cov saw hlau hauv zos.
Qhov tseem ceeb ntawm domestically tsim alumina membrane:
l Qhov no txo qis cov nqi ntawm daim ntawv thov ntawm cov khoom siv ceramics hauv cov xwm txheej kev kho dej, ua rau cov khoom siv tsis zoo rau ntau lub tuam txhab.
l Qhov no tau txhawb nqa kev loj hlob ntawm cov khoom siv hluav taws xob hauv tsev hauv cov khoom siv hluav taws xob thiab tau tsim cov txheej txheem thev naus laus zis rau kev tshawb fawb thiab kev loj hlob ntawm cov khoom siv siab - kawg.
Duab: Alumina ceramic membrane
Txawm li cas los xij, nws qhov kev ua tau zoo tseem ceeb tsis tau dhau los. Nws tseem yog ib qho nyuaj rau kev ua haujlwm ruaj khov rau lub sijhawm ntev nyob rau hauv lub ntsej muag ntawm cov ntsev siab, kub siab thiab muaj zog acid- puag coupling tej yam kev mob nyob rau hauv kev lag luam xws li lub zog tshiab thiab ntsev pas dej tshuaj lom neeg kev lag luam. Kev ua lag luam siab -kawg tseem nyob los ntawm txawv teb chaws cov ntaub ntawv tshwj xeeb membrane.
IV. Kev tawg ntawm Silicon Carbide Ceramic Membranes: Kev daws teeb meem rau "Kev Ua Haujlwm Tsis Txaus Siab" (Tshaj xyoo dhau los)
Nyob rau hauv lub xyoo caum dhau los los yog li ntawd, lub lithium roj teeb, lithium rho tawm los ntawm cov pas dej ntsev, thiab semiconductor industries tau tshwm sim, tsim cov dej khib nyiab nrog tsib yam kev sib txuas: siab salinity, siab kub, muaj zog acid thiab alkali, siab organic teeb meem, thiab siab khoom hais. Alumina yog ruaj khov nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, tab sis nws cov flux decays sai heev nyob rau hauv tej yam kev mob, ua rau nws tsis tsim nyog rau cov lag luam 'nruam qis - downtime ntau lawm xav tau kev pab, hais txog qhov tsis txaus siab ntawm siab - kawg siab inorganic daim nyias nyias.
Raws li cov kev xav tau nruj ntawm siab-qhov kawg ntawm kev ua haujlwm, thiab dhau los ntawm kev lag luam tawg hauv siab -kub sintering thev naus laus zis, silicon carbide ceramic membranes tau tsim. Lawv muaj tag nrho cov txiaj ntsig tseem ceeb ntawm cov ntaub so ntswg inorganic, xws li lub neej ntev, kev ntseeg siab, muaj peev xwm khaws cia cov organic teeb meem, thiab rov ua dua tshiab. Nrog rau cov qauv zoo tshaj plaws crystalline pore, lawv tsim nyog rau ntau yam huab cua thiab cov dej tsis zoo, hais txog qhov tsis txaus ntawm alumina daim nyias nyias hauv kev ua haujlwm.
V. Yav Tom Ntej Kev Lag Luam Trends: Tsav los ntawm ob txoj cai thiab kev ua raws cai, inorganic ceramic membranes tau npaj los ua qhov ntev - lub sij hawm mainstream trend.
Cov pa hauv ultrafiltration membranes qhia tsis muaj qhov sib txawv tseem ceeb hauv lawv lub peev xwm khaws cov pa phem, thiab kev xaiv feem ntau yog raws li tus nqi thiab kev tu tus cwj pwm; Txawm li cas los xij, qhov ntev - lub sij hawm sib txawv ntawm kev lag luam yog txiav txim siab los ntawm ob lub teb chaws txoj cai kev lag luam thiab kev ua raws li PFAS thoob ntiaj teb.
National Industrial Policy yog txhawb kev lag luam:siab -kev ua tau zoo ceramics muaj nyob rau hauv lub teb chaws cov ntaub ntawv tseem ceeb tshiab thiab kev tiv thaiv ib puag ncig txhawb cov khoom catalogs. Ob hom ceramics muaj nyob rau hauv cov npe khoom tseem ceeb ntawm cov ntaub ntawv tseem ceeb tshiab; xoom-emission ceramic membrane technology upgrading tej yaam num tau txais kev pab nyiaj txog li 30 lab yuan ib qhov project; 14th Tsib-Year Plan tshwj xeeb qhov project txuas ntxiv txhawb kev tshawb fawb thiab kev tsim cov ntaub ntawv membrane hauv tsev. Ua ke nrog dual-carbon kev txhim kho, kev siv dej rov qab, thiab kev hloov pauv kev tiv thaiv ib puag ncig, kev lag luam cov txheej txheem xaiv tau hloov ntawm "usable" mus rau "stainable thiab low-kev tu", nrog rau cov lus qhia meej hauv lub tebchaws: ceramic membranes nyiam rau kev kho dej complex, thiab lub zos ntawm high -cov ntaub ntawv membrane kawg tau nce.
Kev ua raws li PFAS:Nrog rau PFAS cov cai tswjfwm hauv Tebchaws Europe thiab Tebchaws Meskas, kev tswj hwm hauv tsev tau maj mam nruj. Kev lag luam organic membrane ntau lawm feem ntau suav nrog kev ntxiv fluorinated additives, ua rau PFAS muaj kuab paug nyob rau hauv tag nrho nws lub neej voj voog. Cov tuam txhab ua lag luam tau maj mam muab cov khoom siv fluorinated organic lim.
Inorganic ceramic membranes yog tsim tsis muaj fluorine, ruaj khov nyob rau hauv cov khoom, tsis muaj PFAS ua raws li kev pheej hmoo, muaj kev pab cuam lub neej 3-5 npaug ntawm cov organic membranes, thiab tsim cov khoom pov tseg tsawg dua. Lawv ua tau raws li cov kev cai tsim khoom ntsuab thiab yuav dhau los ua qhov kev xaiv tseem ceeb rau nruab nrab - mus rau -high-end pom nyob rau hauv nruab nrab mus rau lub sij hawm ntev.
Tuam txhab Taw Qhia - JMFILTEC tsom mus rau kev tshawb fawb thiab kev txhim kho ntawm silicon carbide ceramic membranes
Zhejiang Jianmo Technology Co., Ltd. tau cog lus los tsim cov khoom siv zoo tshaj plaws thiab ruaj khov silicon carbidembrane. Pab neeg nrhiav tau pib cuam tshuam txog R & D ua haujlwm ntawm silicon carbidemembrane cov ntaub ntawv hauv xyoo 2011, thiab tam sim no tau tso cai 8 daim ntawv tsim khoom, thov rau ze li 50 daim ntawv tsim khoom, thiab 6 PCT patents.
