Pakupanga kwa ceramic, kukhuthala kwa glaze slurry ndi gawo lofunika kwambiri, lomwe limakhudza mwachindunji kusinthasintha, kufanana, kusungunuka kwa madzi ndi zotsatira zomaliza za glaze. Kuti mupeze zotsatira zabwino za glaze, ndikofunikira kusankha yoyenera.CMC (Carboxymethyl Cellulose) ngati chokhuthala. CMC ndi polima yachilengedwe yomwe imagwiritsidwa ntchito kwambiri mu ceramic glaze slurry, yokhala ndi makulidwe abwino, mphamvu za rheological komanso kuyimitsidwa.
1. Kumvetsetsa zofunikira za kukhuthala kwa glaze slurry
Mukasankha CMC, choyamba muyenera kufotokoza bwino zomwe zimafunika pa kukhuthala kwa glaze slurry. Ma glaze osiyanasiyana ndi njira zopangira zimakhala ndi zofunikira zosiyana pa kukhuthala kwa glaze slurry. Kawirikawiri, kukhuthala kwakukulu kapena kochepa kwa glaze slurry kumakhudza kupopera, kutsuka kapena kuviika kwa glaze.
Kukhuthala kochepa kwa glaze: koyenera kupopera. Kukhuthala kochepa kwambiri kungatsimikizire kuti glazeyo sidzatseka mfuti yopopera panthawi yopopera ndipo ikhoza kupanga chophimba chofanana.
Kukhuthala kwapakati pa glaze: koyenera kuviika. Kukhuthala kwapakati kungapangitse glaze kuphimba bwino pamwamba pa ceramic, ndipo sikophweka kugwedezeka.
Kukhuthala kwa glaze kochuluka: koyenera kutsukidwa. Kukhuthala kwa glaze kochuluka kumatha kukhala pamwamba kwa nthawi yayitali, kupewa kusungunuka kwambiri, motero kumakhala ndi glaze yokhuthala.
Chifukwa chake, kusankha CMC kuyenera kugwirizana ndi zofunikira pakupanga.
2. Ubale pakati pa magwiridwe antchito a CMC ndi kukhuthala kwake
Kukhuthala kwa AnxinCel®CMC nthawi zambiri kumatsimikiziridwa ndi kulemera kwake kwa mamolekyulu, kuchuluka kwa carboxymethylation ndi kuchuluka kwa zowonjezera.
Kulemera kwa mamolekyulu: Kulemera kwa mamolekyulu a CMC kukakhala kwakukulu, mphamvu yake yokhuthala imakula kwambiri. Kulemera kwa mamolekyulu ambiri kumatha kuwonjezera kukhuthala kwa yankho, kotero kuti limapanga slurry yokhuthala panthawi yogwiritsa ntchito. Chifukwa chake, ngati pakufunika slurry yokhuthala kwambiri ya glaze, CMC yolemera kwambiri ya mamolekyulu iyenera kusankhidwa.
Mlingo wa carboxymethylation: Mlingo wa carboxymethylation wa CMC ukakwera, madzi ake amasungunuka bwino, ndipo amatha kufalikira bwino m'madzi kuti apange kukhuthala kwakukulu. Ma CMC wamba ali ndi madigiri osiyanasiyana a carboxymethylation, ndipo mtundu woyenera ungasankhidwe malinga ndi zofunikira za glaze slurry.
Kuchuluka kwa CMC yowonjezerapo: Kuchuluka kwa CMC yowonjezerapo ndi njira yolunjika yowongolera kukhuthala kwa glaze slurry. Kuwonjezera CMC yochepa kumabweretsa kukhuthala kochepa kwa glaze, pomwe kuwonjezera kuchuluka kwa CMC yowonjezerapo kudzawonjezera kwambiri kukhuthala. Pakupanga kwenikweni, kuchuluka kwa CMC yowonjezerapo nthawi zambiri kumakhala pakati pa 0.5% ndi 3%, kusinthidwa malinga ndi zosowa zinazake.
3. Zinthu zomwe zimakhudza kusankha kwa kukhuthala kwa CMC
Posankha CMC, zinthu zina zofunika kuziganizira ziyenera kuganiziridwa:
a. Kapangidwe ka glaze
Kapangidwe ka glaze kadzakhudza mwachindunji zofunikira zake za kukhuthala. Mwachitsanzo, ma glaze okhala ndi ufa wosalala wambiri angafunike chokhuthala chokhala ndi kukhuthala kwakukulu kuti asunge bwino. Ma glaze okhala ndi tinthu tating'onoting'ono tating'ono sangafunike kukhuthala kwakukulu.
b. Kukula kwa tinthu ta glaze
Magalasi okhala ndi kupyapyala kwambiri amafuna kuti CMC ikhale ndi mphamvu zokhuthala bwino kuti zitsimikizire kuti tinthu tating'onoting'ono titha kuyikidwa mofanana mumadzimadzi. Ngati kukhuthala kwa CMC sikukwanira, ufa wosalala ukhoza kugwa, zomwe zimapangitsa kuti glaze isagwirizane.
c. Kuuma kwa madzi
Kuuma kwa madzi kumakhudza kwambiri kusungunuka ndi kukhuthala kwa CMC. Kupezeka kwa ma ayoni ambiri a calcium ndi magnesium m'madzi olimba kungachepetse kukhuthala kwa CMC komanso kungayambitse mvula. Mukamagwiritsa ntchito madzi olimba, mungafunike kusankha mitundu ina ya CMC kuti muthetse vutoli.
d. Kutentha ndi chinyezi chogwira ntchito
Kutentha ndi chinyezi chosiyanasiyana m'malo ogwirira ntchito zimakhudzanso kukhuthala kwa CMC. Mwachitsanzo, m'malo otentha kwambiri, madzi amasanduka nthunzi mwachangu, ndipo CMC yocheperako ingafunike kuti glaze slurry isakule kwambiri. M'malo mwake, malo otentha pang'ono angafunike CMC yochuluka kuti atsimikizire kukhazikika ndi kusinthasintha kwa slurry.
4. Kusankha ndi kukonzekera CMC mwaluso
Pakugwiritsa ntchito kwenikweni, kusankha ndi kukonzekera kwa CMC kuyenera kuchitika motsatira njira zotsatirazi:
Kusankha mtundu wa AnxinCel®CMC: Choyamba, sankhani mtundu woyenera wa CMC. Pali mitundu yosiyanasiyana ya ma viscosity ya CMC pamsika, yomwe ingasankhidwe malinga ndi zofunikira za ma viscosity ndi zofunikira za glaze slurry. Mwachitsanzo, CMC yolemera pang'ono ya molekyulu ndi yoyenera ma glaze slurry omwe amafuna ma viscosity otsika, pomwe CMC yolemera kwambiri ya molekyulu ndi yoyenera ma glaze slurry omwe amafuna ma viscosity apamwamba.
Kusintha kwa kukhuthala koyesera: Malinga ndi zofunikira za glaze slurry, kuchuluka kwa CMC komwe kumawonjezeredwa kumasinthidwa mwachisawawa. Njira yodziwika bwino yoyesera ndi kuwonjezera CMC pang'onopang'ono ndikuyesa kukhuthala kwake mpaka kufika pamlingo wofunikira wa kukhuthala.
Kuyang'anira kukhazikika kwa glaze slurry: glaze slurry yokonzedwayo iyenera kusiyidwa kuti iime kwa kanthawi kuti ione kukhazikika kwake. Yang'anani ngati pali mvula, kuchuluka kwa madzi, ndi zina zotero. Ngati pali vuto, kuchuluka kapena mtundu wa CMC kungafunike kusinthidwa.
Sinthani zowonjezera zina: Mukagwiritsa ntchitoCMC, ndikofunikiranso kuganizira kugwiritsa ntchito zowonjezera zina, monga zotulutsira madzi, zoyezera, ndi zina zotero. Zowonjezerazi zitha kuyanjana ndi CMC ndikukhudza mphamvu yake yokhuthala. Chifukwa chake, posintha CMC, ndikofunikiranso kulabadira chiŵerengero cha zowonjezera zina.
Kugwiritsa ntchito CMC mu ceramic glaze slurry ndi ntchito yaukadaulo kwambiri, yomwe imafuna kuganizira mozama ndikusintha kutengera zofunikira pakukhuthala, kapangidwe kake, kukula kwa tinthu, malo ogwiritsira ntchito ndi zinthu zina za glaze slurry. Kusankha koyenera ndi kuwonjezera AnxinCel®CMC sikungongowonjezera kukhazikika ndi kusinthasintha kwa glaze slurry, komanso kumawonjezera zotsatira zomaliza za glaze. Chifukwa chake, kukonza ndikusintha njira yogwiritsira ntchito CMC popanga ndiye chinsinsi chotsimikizira mtundu wa zinthu za ceramic.
