Maitiro ekubatanidza hpmc mumakramic membranes?

HydroxyPropyl methylcellose (HPMC), semanyorero epolymen, inowanzoshandiswa muminda yakasiyana-siyana yeindasitiri, kusanganisira kuvaka, chikafu, mishonga, mishonga. Mumakore achangopfuura, HPMC yakaratidzawo mukana mukuru mukugadzirira uye kushandisa kwecramic membranes. Ceramic membranes inoshandiswa zvakanyanya mukurapwa kwemvura, makemikari, mishonga uye mamwe maindasitiri nekuda kwesimba ravo rakakura, rakanyanya kupisa, acid uye alkali kuramba uye humwe hunhu. HPMC yave zvishoma nezvishoma leaventialary auxiliary mumiririri weCeramic membranes nekuvandudza chimiro cheCeramic membranes, achivandudza kuita kwavo uye optimizing maitiro avo ekugadzirira.

1. Basic hunhu hweHPMC uye Sumo kuMetires membranes
HPMC is non-ionic cellulose ether neakanaka mvura solubility, iyo thermal gelation, firimu-inoumba uye inokoshesa zvinhu. Aya maitiro eHPMC anogonesa kugovera zviri nani kushanda kwekuita uye kuita kwechigadzirwa mune akawanda magadziriso maitiro. Mukugadzirira kweCeramic membranes, HPMC inonyanya kutamba zvigaro zvakawanda senge pore formers, mabhasiketi, uye modifiers.

Ceramic membrane zvinhu zvemhando nemakroni ane microupuss zvakagadzirwa nekuchinjisa zvinhu zvemhando (senge alumina, titanium dioxide, titc.), ine simba repamoyo uye simba rakanyanya kunaka. Ceramic membranes inoshandiswa zvakanyanya mumvura kurapwa kwemvura, chikafu uye chinwiwa filtration, mishonga yekuparadzaniswa uye mamwe minda. Nekudaro, maitiro ekugadzirira emakramu emakramini anoomeserwa, kunyanya mumutemo wePore dhizaini, iyo density yemidziyo yemamrene uye kufanana kwemamrembo. Naizvozvo, vanowedzera vanowedzera seHPMC inogona kubatsira zvakanyanya chimiro uye kuita kweCeramic membranes.

2. Basa reHPMC mukugadzirira kweCeramic membranes
Basa rePore Formers
Munguva yekugadzirira kwemakramita membranes, midziyo meurme inoda kuve nekukonzeresa kwakakodzera uye saizi yekugovera kuti ive nechokwadi chekutsamwa kwavo kwakanaka. HPMC, seyavaimbova pore, inogona kushongedza panguva yekuchinjisa nzira yeCeramic membrane zvinhu kugadzira yunifomu poda chimiro. Hpmc ichora uye inosemesa tembiricha yakakwirira, uye haizombogara iri mumakremeri embrane, nekudaro inogadzira yakadzorwa size saizi uye kugovera. Mhedzisiro iyi inoita HPMC yakakosha yekugadzirira mukugadzirira kwe microuporous uye ultrafiltration ceramic membranes.

Simbisa iyo mechancal zvivakwa zve membrane zvinhu
HPMC ine yakanaka firimu-inogadzira zvivakwa uye inogona kuwedzera iyo mechancal zvivakwa zveMembrane zvinhu panguva yekugadzirira kwemakramu emeramic. Muchikamu chekutanga cheCeramic membrane kuumbwa, HPMC inogona kushandiswa seyakagadzirwa nemidziyo yemepurene kuti uwedzere kudyidzana pakati pemasangano uye nekuvandudza simba rose uye kugadzikana kwemakramita membranes. Kunyanya mukugadzira ceramic membranes, HPMC inogona kudzivirira kupaza uye defformation yeMembrane Clanks uye simbisai simba rembrane rembrane mushure mekuchinjisa.

Kuvandudza density uye kufanana kweCeramic membranes
HPMC inogona zvakare kuvandudza density uye kufanana kwemambrames embrames. Mugadziriro yekugadzirira yeCeramic membranes, iyo yunifomu yekugoverwa yeMembrane zvinhu zvakakosha pakuita kweiyo membrane. HPMC ine yakanakisa kupararira uye inogona kubatsira ceramic podeers kuti igovaniswe nemhinduro, nokudaro ichidzivirira kuremara kana kusaenzana kwenzvimbo muzvinhu zvemukati. Uye zvakare, iyo viscosity yeHPMC mumhinduro inogona kudzora chiyero cheCerimic yeCeramic Pound

Kuvandudza nzvimbo yemukati ye cramic membranes
Chimwe chinhu chikuru cheHPMC ndechekuvandudza nzvimbo yemapepa emakramic membranes, kunyanya maererano neiyo hydrophilikuity uye anti-inonetsa zvivakwa zve membrane. HPMC inogona kugadzirisa midziyo yemakemikari yeiyo membrane pamusoro peiyo gadziriro yeCeramic membranes, ichiita kuti iite hydrophilic, nekudaro ichisimudzira kugona kwemweya wekunyepedzera. Mune zvimwe zvekushandisa, pamusoro peiyo ceramish membrane inodhindwa nyore nyore nevanopa uye kutadza. Kuvapo kweHPMC kunogona kuderedza zvinobudirira kuitika kwechimwe chinhu uye kuwedzera hupenyu hwebasa hwemanyorerwe embrane.

3. Synergistic mhedzisiro yeHPMC uye zvimwe zvinowedzera
Mukugadzirira kweCeramic membranes, HPMC inowanzo kushanda muSynergy nevamwe vanowedzera (senge maplineti, vanoparadzira, stabilizders, etc.) kuti vagadzirise mashandiro eMembrane. Semuenzaniso, kushandiswa kwakabatanidzwa nevapurasitiki kunogona kuita kuti chifukidze kwemakremi embranes yakawanda yunifomu panguva yekuchengetera uye kudzivirira chizvarwa chemaza. Uye zvakare, iyo synergistic mhedzisiro yeHPMC uye inoparadzira inobatsira kugovera ceramic poder, kugadzirisa kufanana kweMembrane zvinhu uye kudzorwa kweiyo pore dhizaini.

HPMC inowanzoshandiswa pamwe chete nemamwe mimwe polymer zvinhu senge polyethylene glycol (peg) uye polyvinyl pyrrodidone (pvp). Izvi zvinhu zvekushandisa polymin zvinogona kuwedzera kuenzana nehukuru hwekuita uye kugoverwa kwemakramini membranes, nekudaro achizadzisa dhizaini yekuchinja kweiyo akasiyana fiiltration zvinodiwa. Semuenzaniso, peg ine yakanaka pore-kugadzira maitiro. Kana ichishandiswa pamwe chete neHPMC, iyo microupus chimiro chemakramic membranes inogona kudzorwa nenzira kwayo, nekuvandudza kushanda kwehurongwa hweMEMRANY.

4. Maitiro ekuyerera kweHPMC kubatanidzwa muCeramic membrane
Maitiro ekubatanidza HPMC muCeramic membrane anowanzo kusanganisira matanho anotevera:

Kugadzirira kweCeramic Slurry
Kutanga, ceramic poda (senge alumina kana zirconium oxide) inosanganiswa neHPMC uye zvimwe zvinowedzera kugadzirira cramic slurry ine imwe fluidity. Kuwedzerwa kweHPMC kunogona kugadzirisa vhiza uye kuvharirwa kweiyo slurry uye kuve nechokwadi chekuparadzirwa kwunifomu yeCeramic poda mune slurry.

Membrane fomu
Iyo ceramic slurry inoumbwa mune iyo inodiwa membrane isina kana nzira dzakadai sekukanda, kubuda kana jekiseni. Muchiitiko ichi, HPMC inogona kudzivirira zvinobudirira kupaza uye deformation yemamrene isina chinhu uye kugadzirisa kusaenzana kwemamriyasi.

Kuomesa uye kutadza
Mushure mekunge membrane isina chinhu yaoma, inotakurirwa tembiricha yakanyanya. Muchiitiko ichi, HPMC inotyisa pakudziya kwakanyanya, ichisiya chimiro chePore, uye pakupedzisira inoumba mendane yembrane ine saizi yavanoda pore uye porosity.

Post-kurapwa kweMembrane
Mushure mekutadza, iyo ceramish membrane inogona kutumirwa zvichienderana nezvinodiwa zvekushandisa, zvakadai sekushandurwa kwemusoro, kuunganidza kana kuwedzera kurapwa, kuenderera mberi nekuwedzera kuita kwayo.

5. Tarisiro nematambudziko eHPMC mune ceramic membrane application
HPMC ine mapepa ekunyorera tarisiro yekugadzirira yemakramu emambrames, kunyanya mukunyorwa kwemvura senge kurapwa kwemvura uye gasi kupatsanurwa, uko hpmc zvakanyanya kuvandudza mashandiro emakramic membranes. Nekudaro, vakasara veHPMC panguva yakakwira-tembiricha muchiparadza uye nekuita kwayo pakugadzikana kwenguva refu kweMembrane vachiri kuda kufunda. Mukuwedzera, nzira yekuwedzera kudzokorora basa rayo mumakreme membera kuburikidza ne molecular dhizaini yeHPMC zvakare ndiyo nhungamiro yakakosha yekutsvaga ramangwana rekutsvaga mune ramangwana research

Semumiriri akakosha ebetsero mugadziriro yeCeramic membranes, HPMC yakaita chimwe chezvinhu zvakakosha pakugadzirira kwemakremi manhamba akadai seyakagadzirwa midziyo, yakavandudzwa density uye yakavandudzwa midziyo uye yakavandudzwa nzvimbo. Mune ramangwana, nekukura kuri kuenderera kweCeramir
