Kodi mungaphatikize bwanji HPMC mu ceranes?

Hydroxypropyl methylcellulose (hpmc), monga zinthu za polymer, nthawi zambiri zimagwiritsidwa ntchito m'minda yosiyanasiyana ya mafakitale, kuphatikizapo zomanga, chakudya, mankhwala ena. M'zaka zaposachedwa, HPMC yawonetsanso kuthekera kwakukulu pakukonzekera ndi kugwiritsa ntchito ma nembanemba a ceranes. Ceranes Membranes amagwiritsidwa ntchito kwambiri pamadzi chithandizo chamadzi, mankhwala, mafakitale am'madzi ndi makampani ena chifukwa cha mphamvu zawo zapamwamba, acid ndi alkali kukana ndi mawonekedwe ena. Pang'onopang'ono amakhala othandiza othandizira pakukonzekera ma nembanemba pokonza ma memberalic mwakuwongolera ma nembanemba a curamic, kukonza magwiridwe awo ndikukonza njira yawo yokonzekera.

1. Makhalidwe oyambira a HPMC ndi mawu oyamba kwa ceranes
HPMC ndi ma cellulose osaya ndi ether ndi madzi abwino osungunuka, miyala yamafuta, kupanga filimu ndi kukongoletsa. Makhalidwe awa a hpmc amathandizira kuti apatse bwino ntchito ndi magwiridwe antchito ambiri okonzekera. Pokonzekera ma nembanemba a cpmmic, hpmc makamaka amasewera maudindo angapo monga zolumikizana m'malo, kumanga, ndi osinthira.

Ceranec Insphranes ndi zida za membrane wokhala ndi zigawo zazikuluzikulu zopangidwa ndi zikwangwani zakunja (monga alumuna, zircanium oxide, etc.), ndi mphamvu yamankhwala abwino kwambiri. Ceranes Membranes amagwiritsidwa ntchito kwambiri pamadzi chithandizo chamadzi, chakudya ndi chakumwa chakumwa, kupatukana kwamankhwala ndi minda ina. Komabe, kukonzekera kukhazikitsa kwa ceramic kumakhala kovuta, makamaka mu kapangidwe ka manyowa, kachulukidwe ka zinthu za membrane ndi kufanana kwa nembanemba pamtunda. Chifukwa chake, kuwonjezera zowonjezera monga HPMC imatha kusintha kapangidwe kake ndi magwiridwe antchito a ceranes.

2. Udindo wa HPMC pakukonzekera kwa ceranes
Udindo wa Pamers
Pakukonzekera ma nembanemba, zinthu za membrane zimafunikira kukhala ndi chidwi komanso kugawana kalulidwe kazithunzi kuti mutsimikizire kuti mwasintha. HPMC, ngati porekale, imatha kusanzira panthawi yochimwa kwazinthu zam'madzi kuti zipange kapangidwe kake. HPMC idzawola ndikusunga kutentha kwambiri, ndipo sadzakhalabe mu mzere wa cerane, potero kupanga ma corelable akuluakulu oyang'anira komanso kugawa. Izi zimapangitsa kuti HPMC ikhale yofunika pakukonzekera microroous ndi ultraframic curanes.

Kumalimbikitsa mphamvu zamakina a membrane zida
HPMC ili ndi katundu wabwino kwambiri wamakanema ndipo amatha kukulitsa makina opanga ma membrane pokonzekera cmeranes. Kumayambiriro kwa mapangidwe a ceraner, hpmc imatha kugwiritsidwa ntchito ngati chomangira cha zinthu za membrane kuti ziwonjezeke pakati pa tinthu tambiri, potero ndikuwongolera mphamvu zonse komanso kukhazikika kwa ma nembrane. Makamaka pakupanga ma nembanemba a cpminec, hpmc amatha kupewa kuwonongeka ndi kuwonongeka kwa ma membrane and onetsetsani kuti mphamvu ya cerac itatha.

Sinthani kachulukidwe ndi kufanana kwa ma nembanemba
HPMC imatha kusintha kachulukidwe ndi kufanana kwa ma nembanemba a ceranes. Pokonzekera ma nembanemba a ceranes, kugawa yunifolomu ya membrane ndikofunikira pakuchita kwa nembanemba. HPMC ili ndi kuchuluka kwabwino ndipo kumathandizanso kufalikira kwa ceramited mu yankho, popewa zolakwika kapena zopanda pake mu nembanemba. Kuphatikiza apo, mafayilo a HPMC mu yankho amatha kuwongolera ufa wowuma wa ceramic, ndikupanga membrane zinthu zowoneka bwino komanso zosalala pakupanga.

Sinthani malo okhala a ceramic membrane
Udindo wina waukulu wa HPMC ndikuwongolera mawonekedwe a ceramic membrane, makamaka molingana ndi hydrophilicity ndi ma odana ndi ma membrane. HPMC imatha kusintha mankhwala a nembanemba pamzere pokonzekera ma nembanemba, ndikupangitsa kuti ikhale yambiri hydrophilic, motero imalimbikitsa luso la member. Muzosankha zina, mawonekedwe a ma nembanemba a ceramic ndi adsorbed wosavuta ndi zodetsa ndikulephera. Kukhalapo kwa HPMC kumatha kuchepetsa bwino komwe kumachitika chifukwa cha zodabwitsazi ndikuwonjezera moyo wautumiki wa curacne.

3. Zotsatira zoyipa za HPMC ndi zina zowonjezera
Pokonzekera kuchuluka kwa ceranes, hpmc nthawi zambiri kumagwira ntchito ku Synergy ndi zina zowonjezera (monga ma pulasitiki, omwazika, okhazikika, otsutsa, etc.) kuti mukonze magwiridwe a nembanemba. Mwachitsanzo, kugwiritsa ntchito mankhwala omwe amaphatikizidwa ndi mafayilo kumatha kupanga shranage ma yunifolomu yunifolomu yambiri pakuchimwa ndikuletsa m'badwo wa ming'alu. Kuphatikiza apo, synergistist zotsatira za HPMC ndi zodetsa zimathandizira kugawa kwambiri ufa wa ceramic, kusintha mafano a membrane komanso owongolera kapangidwe kake.

HPMC imagwiritsidwanso ntchito kuphatikiza ndi zida zina za polymer monga polyethylene glycol (msomali) ndi polyvinyl piryulone (pvp). Zipangizo za polymer zimatha kusintha kukula ndi kugawa kwa curamic membranes, potero kutsata kusinthasintha kwa zofuna za kufalizidwa. Mwachitsanzo, namba ali ndi mphamvu yopanga pore. Mukamagwiritsidwa ntchito limodzi ndi hpmc, machenjera amtundu wa ceramic amatha kuwongoleredwa molondola, potengera kusinthasintha kwa fayilo ya nembanemba.

4. Makina ophatikizira a HPMC Kuphatikiza kwa ceramic membrane
Njira yophatikizira HPMC mu cerac mu cerane nthawi zambiri imakhala ndi izi:

Kukonzekera kwa ceramic slider
Choyamba, matenda a ceramic (monga alumina kapena zirconium oxide) amasakanikirana ndi HPMC ndi zina zowonjezera kuti akonzekeretsetseko pang'ono. Kuphatikiza kwa hpmc kumatha kusintha mamasukidwe ndi kupondereza kwa slurry ndikuwonetsetsa kuti kufalikira kwa ceramic ufa mu slurry.

Kupanga membrane
Ceramic slurry imapangidwa mu membrane wofunikira wopanda njira monga kuponyera, potuluka kapena jakisoni. Munjira iyi, hpmc imatha kupewa kusokonekera ndi kusokonekera kwa nembanemba yopanda tanthauzo ndikusintha mafangane.

Kuyanika ndi Kuchimwa
Pambuyo pa nembanemba kapena zouma, zimachimwira kutentha kwambiri. Munjira iyi, hpmc Volatilishiz pamtunda wapamwamba, kusiya chojambula, ndipo pamapeto pake chimapanga ma nembanemba ndi mawonekedwe ofunikira.

Kutumiza kwa membrane
Pambuyo muchikunja, mzere wa ceramic umatha kuthandizidwa malinga ndi zofunika kugwiritsa ntchito, monga kudzisintha kwapakati, kuphatikizika kapena njira zina zogwirizira, kuti muthe kukonza momwe akugwirira ntchito.

5. Ziyembekezo ndi zovuta za hpmc mu cerac membrane mapulogalamu
HPMC ili ndi chiyembekezo chothandiza pakukonzekera kwa curamic membrane, makamaka pamapulogalamu omaliza monga chithandizo chamadzi ndi kupatukana kwamadzi, komwe HPMC imathandizira ma nembanemba. Komabe, zotsalira za HPMC nthawi yamagetsi yotentha kwambiri komanso zomwe zimapangitsa kukhazikika kwakanthawi kwa nembanemba kumafunikiranso kuphunzira. Kuphatikiza apo, momwe angakwaniritsire kuti mukwaniritse gawo lake muyeso wa ceramic kudzera mwa mapangidwe a HPMC ndi njira yofunika yofufuzira mtsogolo.

Monga wothandizira wothandizira wa aramilariry pokonzekera ceranes, HPMC yakhala imodzi mwazinthu zofunikira pakukonzekera mivi yambiri monga kapangidwe kake, zowonjezera zopanga, zotukuka bwino. M'tsogolomu, ndikukula kosalekeza kwaukadaulo wa cpramic membrane, HPMC idzagwira ntchito yofunika kwambiri m'minda yonseyi, kulimbikitsa kusintha kwa magwiridwe antchito ndi kusintha kwa ma nembrane.
