Popanga ceramic, kukhuthala kwa glaze slurry ndi gawo lofunikira kwambiri, lomwe limakhudza mwachindunji kusungunuka, kufanana, kusungunuka komanso kutsekemera komaliza kwa glaze. Kuti mupeze zotsatira zabwino za glaze, ndikofunikira kusankha yoyeneraCMC (Carboxymethyl cellulose) ngati thickener. CMC ndi chilengedwe polima pawiri ambiri ntchito ceramic glaze slurry, ndi thickening zabwino, rheological katundu ndi kuyimitsidwa.
1. Kumvetsetsa zofunikira za viscosity za glaze slurry
Posankha CMC, choyamba muyenera kufotokozera zofunikira za viscosity za glaze slurry. Kunyezimira kosiyanasiyana ndi njira zopangira zimakhala ndi zofunikira zosiyanasiyana pakuwoneka bwino kwa glaze slurry. Nthawi zambiri, kukhuthala kokwera kwambiri kapena kutsika kwambiri kwa glaze slurry kumakhudza kupopera mbewu, kutsuka kapena kumizidwa kwa glaze.
Low viscosity glaze slurry: oyenera kupopera mbewu mankhwalawa. Kutsika kwambiri mamasukidwe akayendedwe kungachititse kuti glaze kutsekereza mfuti kupopera mbewu mankhwalawa ndi kupanga ❖ kuyanika yunifolomu.
Medium viscosity glaze slurry: oyenera kuviika. Kukhuthala kwapakatikati kumatha kupangitsa kuti glaze ikhale yofanana kuphimba pamwamba pa ceramic, ndipo sikophweka kugwa.
High viscosity glaze slurry: oyenera kuchitira brushing. Mkulu mamasukidwe akayendedwe glaze slurry akhoza kukhala padziko kwa nthawi yaitali, kupewa mopitirira muyeso fluidity, motero kupeza thicker glaze wosanjikiza.
Chifukwa chake, kusankha kwa CMC kuyenera kugwirizana ndi zofunikira pakupangira.
2. Ubale pakati pa kukhuthala kwa magwiridwe antchito ndi kukhuthala kwa CMC
Kukhuthala kwa AnxinCel®CMC nthawi zambiri kumatsimikiziridwa ndi kulemera kwake kwa maselo, kuchuluka kwa carboxymethylation ndi kuchuluka kwake.
Kulemera kwa mamolekyu: Kulemera kwa mamolekyu a CMC kumapangitsa kuti mphamvu yake ikhale yolimba. A apamwamba maselo kulemera kuonjezera mamasukidwe akayendedwe a yankho, kotero kuti amapanga thicker slurry pa ntchito. Choncho, ngati apamwamba mamasukidwe akayendedwe glaze slurry chofunika, mkulu maselo kulemera CMC ayenera kusankhidwa.
Digiri ya carboxymethylation: Kukwera kwa digiri ya carboxymethylation ya CMC, kumapangitsa kuti madzi asungunuke kwambiri, ndipo amatha kumwazikana bwino m'madzi kuti apange mawonekedwe apamwamba. Ma CMC wamba ali ndi magawo osiyanasiyana a carboxymethylation, ndipo mitundu yoyenera imatha kusankhidwa malinga ndi zofunikira za glaze slurry.
Kuchuluka kowonjezera: Kuchulukitsa kwa CMC ndi njira yachindunji yowongolera kukhuthala kwa glaze slurry. Kuonjezera CMC pang'ono kudzachititsa kutsika mamasukidwe akayendedwe a glaze, pamene kuwonjezera kuchuluka kwa CMC anawonjezera kwambiri kuonjezera mamasukidwe akayendedwe. Pakupanga kwenikweni, kuchuluka kwa CMC yowonjezeredwa nthawi zambiri kumakhala pakati pa 0.5% ndi 3%, kusinthidwa malinga ndi zosowa zenizeni.
3. Zinthu zomwe zimakhudza kusankha kwa kukhuthala kwa CMC
Posankha CMC, zinthu zina zokopa ziyenera kuganiziridwa:
a. Kupanga kwa glaze
Kupangidwa kwa glaze kudzakhudza mwachindunji zofuna zake za viscosity. Mwachitsanzo, ma glaze okhala ndi ufa wochuluka wa ufa angafunike chokhuthala chokhala ndi mamasukidwe apamwamba kuti asunge kuyimitsidwa bwino. Zowala zokhala ndi tinthu tating'onoting'ono sizingafune kukhuthala kwambiri.
b. Glaze kukula kwa tinthu
Magalasi okhala ndi fineness apamwamba amafunikira CMC kuti ikhale ndi zinthu zokhuthala bwino kuti zitsimikizire kuti tinthu tating'onoting'ono titha kuyimitsidwa bwino mumadzimadzi. Ngati kukhuthala kwa CMC sikukwanira, ufa wabwino ukhoza kugwa, zomwe zimapangitsa kuti pakhale glaze yosiyana.
c. Madzi kuuma
Kuuma kwa madzi kumakhudza kwambiri kusungunuka ndi kukhuthala kwa CMC. Kukhalapo kwa ayoni ambiri a calcium ndi magnesium m'madzi olimba kumatha kuchepetsa kukhuthala kwa CMC komanso kuyambitsa mvula. Mukamagwiritsa ntchito madzi olimba, mungafunike kusankha mitundu ina ya CMC kuti muthane ndi vutoli.
d. Ntchito kutentha ndi chinyezi
Kutentha kosiyanasiyana kwa malo ogwira ntchito ndi chinyezi kudzakhudzanso kukhuthala kwa CMC. Mwachitsanzo, m'malo otentha kwambiri, madzi amasanduka nthunzi mofulumira, ndipo CMC yotsika kwambiri imafunikanso kupewa kuwonjezereka kwa glaze slurry. M'malo mwake, malo otsika kutentha angafunike apamwamba mamasukidwe akayendedwe CMC kuonetsetsa bata ndi fluidity wa slurry.
4. Kusankha mwanzeru ndi kukonzekera kwa CMC
Pakugwiritsa ntchito kwenikweni, kusankha ndikukonzekera CMC kuyenera kuchitika motengera izi:
Kusankhidwa kwa mtundu wa AnxinCel®CMC: Choyamba, sankhani mitundu yoyenera ya CMC. Pali mitundu yosiyanasiyana ya mamasukidwe akayendedwe a CMC pamsika, omwe amatha kusankhidwa molingana ndi zomwe zimafunikira kukhuthala komanso kuyimitsidwa kwa glaze slurry. Mwachitsanzo, otsika maselo kulemera CMC ndi oyenera glaze slurries amafuna otsika mamasukidwe akayendedwe, pamene mkulu maselo kulemera CMC ndi oyenera glaze slurries amafuna mkulu mamasukidwe akayendedwe.
Kusintha koyeserera kwa mamasukidwe akayendedwe: Malinga ndi zofunikira za glaze slurry, kuchuluka kwa CMC yowonjezeredwa kumasinthidwa moyesera. Njira yoyesera yodziwika ndikuwonjezera pang'onopang'ono CMC ndikuyesa mamasukidwe ake mpaka makulidwe omwe amafunidwa afika.
Kuyang'anira kukhazikika kwa glaze slurry: Chokongoletsedwa cha glaze slurry chiyenera kusiyidwa kuti chiyime kwa kanthawi kuti chiwone kukhazikika kwake. Onani ngati pali mvula, kusakanikirana, ndi zina zotero. Ngati pali vuto, kuchuluka kapena mtundu wa CMC ungafunike kusinthidwa.
Sinthani zowonjezera zina: Mukamagwiritsa ntchitoCMC, m'pofunikanso kuganizira kugwiritsa ntchito zina zowonjezera, monga dispersants, leveling agents, etc. Zowonjezera izi zikhoza kugwirizana ndi CMC ndi kukhudza zotsatira zake za thickening. Choncho, pokonza CMC, m'pofunikanso kumvetsera chiŵerengero cha zowonjezera zina.
Kugwiritsiridwa ntchito kwa CMC mu ceramic glaze slurry ndi ntchito yapamwamba kwambiri, yomwe imafuna kuganizira mozama ndikusintha malinga ndi zofunikira za kukhuthala, kapangidwe kake, kukula kwa tinthu, malo ogwiritsira ntchito ndi zinthu zina za glaze slurry. Kusankhidwa koyenera ndi kuwonjezera kwa AnxinCel®CMC sikungangowonjezera kukhazikika ndi kusungunuka kwa glaze slurry, komanso kumapangitsanso kutsekemera komaliza. Chifukwa chake, kukhathamiritsa mosalekeza ndikusintha kagwiritsidwe ntchito ka CMC popanga ndiye chinsinsi chowonetsetsa kuti zinthu za ceramic zili bwino.
