Mphamvu ya Carboxymethyl Cellulose (CMC) pa Makhalidwe a Ceramic Slurry

Carboxymethyl cellulose (CMC) ndi polima yosungunuka m'madzi yochokera ku cellulose yomwe imakhala ndi ntchito zambiri m'mafakitale osiyanasiyana.M'makampani a ceramics, CMC imagwiritsidwa ntchito ngati binder ndi rheology modifier mu ceramic slurry formulations.Kuphatikizika kwa CMC kumatha kukhudza kwambiri zinthu za ceramic slurry, kuphatikiza kukhuthala kwake, machitidwe a rheological, komanso kukhazikika.M'nkhaniyi, tikambirana za mphamvu ya CMC pa katundu wa ceramic slurry.

Viscosity

Kuphatikiza kwa CMC ku ceramic slurry kumatha kukulitsa kukhuthala kwake.Izi zimachitika chifukwa cha kulemera kwakukulu kwa maselo ndi kulowetsedwa kwakukulu kwa CMC, zomwe zimabweretsa kukhuthala kwakukulu ngakhale pazigawo zochepa.CMC imagwira ntchito ngati thickening wothandizira, kukulitsa kukhuthala kwa ceramic slurry ndikuwongolera kuthekera kwake kumamatira pamwamba pa thupi la ceramic.

Rheological Khalidwe

CMC imathanso kukhudza machitidwe a rheological a ceramic slurry.Rheology ya ceramic slurry ndiyofunikira pakukonza ndi magwiridwe ake.Kuwonjezera kwa CMC kungapangitse khalidwe lometa ubweya wa ubweya, kumene kukhuthala kwa slurry kumachepa pamene kumeta ubweya kumawonjezeka.Izi zitha kukhala zopindulitsa pakukonza, chifukwa zimalola kuti slurry aziyenda mosavuta pakuponya, kuumba, kapena zokutira.Makhalidwe a rheological a slurry amathanso kukhudzidwa ndi ndende, kulemera kwa maselo, komanso kuchuluka kwa m'malo mwa CMC.

Kukhazikika

CMC ikhoza kupititsa patsogolo kukhazikika kwa ceramic slurry popewa kukhazikika kapena kulekanitsa tinthu tating'onoting'ono.Kuwonjezera CMC akhoza kulenga kuyimitsidwa khola ndi kuonjezera mamasukidwe akayendedwe a slurry, kuwongolera luso lake kugwira particles mu kuyimitsidwa.Izi ndizofunikira makamaka pamapulogalamu omwe matope amayenera kusungidwa kapena kunyamulidwa mtunda wautali, chifukwa kukhazikika kapena kupatukana kungayambitse zokutira zosagwirizana kapena kuwombera kosagwirizana.

Kugwirizana

Kugwirizana kwa CMC ndi zigawo zina za ceramic slurry ndizofunikiranso kuziganizira.CMC ikhoza kuyanjana ndi zigawo zina, monga dongo, feldspars, ndi zomangira zina, zomwe zimakhudza katundu wawo ndi ntchito.Mwachitsanzo, kuwonjezera kwa CMC kumatha kusintha zomwe zimamangiriza dongo, zomwe zimapangitsa kuti matupi a ceramic akhale amphamvu komanso olimba.Komabe, kuchuluka kwa CMC kumatha kupangitsa kuti pakhale matope ambiri, zomwe zimapangitsa kuti pakhale zovuta pakukonza ndi kugwiritsa ntchito.

Mlingo

Mlingo wa CMC mu ceramic slurry ndichinthu chofunikira kuganizira.Mlingo wokwanira wa CMC udzatengera momwe amagwiritsira ntchito, komanso momwe slurry imagwirira ntchito komanso momwe mukufuna.Nthawi zambiri, kuchuluka kwa CMC mu ceramic slurry kumatha kuyambira 0.1% mpaka 1%, kutengera ntchito.Kuchulukirachulukira kwa CMC kumatha kupangitsa kuti pakhale matope ochulukirapo komanso okhazikika, komanso kungayambitsenso zovuta pakukonza ndi kugwiritsa ntchito.

Mapeto

Mwachidule, CMC imatha kukhudza kwambiri mawonekedwe a ceramic slurry, kuphatikiza ma viscosity, machitidwe a rheological, kukhazikika, kuyanjana, ndi mlingo.Pomvetsetsa mphamvu ya CMC pazinthu izi, ndizotheka kukulitsa magwiridwe antchito a ceramic slurry pazinthu zosiyanasiyana, monga kuponyera, kuumba, zokutira, kapena kusindikiza.Kugwiritsiridwa ntchito kwa CMC m'mapangidwe a ceramic slurry kungapangitse kukonzanso, kugwira ntchito, ndi kulimba kwa zinthu za ceramic.
