Enqubweni yokukhiqiza ye-ceramic, i-viscosity ye-glaze slurry iyipharamitha ebaluleke kakhulu, ethinta ngokuqondile uketshezi, ukufana, ukuthungwa kanye nomphumela wokugcina we-glaze. Ukuze uthole umphumela ofanele we-glaze, kubalulekile ukukhetha okufaneleI-CMC (Carboxymethyl Cellulose) njenge-thickener. I-CMC iyinhlanganisela ye-polymer yemvelo evame ukusetshenziswa ku-ceramic glaze slurry, enokuqina okuhle, izakhiwo ze-rheological kanye nokumiswa.
1. Qonda izidingo ze-viscosity ze-glaze slurry
Lapho ukhetha i-CMC, udinga kuqala ukucacisa izidingo ze-viscosity ze-glaze slurry. Ukucwebezela okuhlukile nezinqubo zokukhiqiza kunezidingo ezihlukene ze-viscosity ye-glaze slurry. Ngokuvamile, i-viscosity ephezulu kakhulu noma ephansi kakhulu ye-glaze slurry izothinta ukufuthwa, ukuxubha noma ukucwiliswa kwe-glaze.
I-viscosity glaze slurry ephansi: ilungele inqubo yokufafaza. I-viscosity ephansi kakhulu ingaqinisekisa ukuthi i-glaze ngeke ivale isibhamu se-spray ngesikhathi sokufafaza futhi ingakha ukunamathela okufanayo okufanayo.
I-viscosity glaze slurry emaphakathi: ilungele inqubo yokucwilisa. I-viscosity emaphakathi ingenza i-glaze imboze ngokulinganayo indawo yobumba, futhi akulula ukucwila.
I-viscosity glaze slurry ephezulu: ilungele inqubo yokuxubha. I-viscosity glaze slurry ephezulu ingahlala ngaphezulu isikhathi eside, igweme uketshezi oluningi, futhi ngaleyo ndlela ithole ungqimba olucwebezelayo olujiyile.
Ngakho-ke, ukukhethwa kwe-CMC kudinga ukuhambisana nezidingo zenqubo yokukhiqiza.
2. Ubudlelwano phakathi kokuqina nokusebenza kwe-viscosity ye-CMC
Ukusebenza kokuqina kwe-AnxinCel®CMC kuvame ukunqunywa isisindo sayo samangqamuzana, izinga le-carboxymethylation kanye nenani elingeziwe.
Isisindo samangqamuzana: Uma siphakama isisindo samangqamuzana e-CMC, kulapho umphumela wawo wokujiya uqine. Isisindo samangqamuzana esiphezulu singandisa i-viscosity yesisombululo, ukuze sakhe udaka olukhudlwana ngesikhathi sokusetshenziswa. Ngakho-ke, uma i-viscosity glaze slurry ephakeme idingeka, kufanele kukhethwe i-CMC yesisindo samangqamuzana aphezulu.
Izinga le-carboxymethylation: Uma liphakama izinga le-carboxymethylation ye-CMC, kuqina ukuncibilika kwayo emanzini, futhi ingahlakazeka ngokuphumelelayo emanzini ukuze yakhe i-viscosity ephakeme. Ama-CMC ajwayelekile anamadigri ahlukene e-carboxymethylation, futhi izinhlobonhlobo ezifanele zingakhethwa ngokuya ngezidingo ze-glaze slurry.
Inani elingeziwe: Inani elingeziwe le-CMC liyindlela eqondile yokulawula i-viscosity ye-glaze slurry. Ukwengeza i-CMC encane kuzoholela ekukhanyeni okuphansi kwe-glaze, kuyilapho ukwandisa inani le-CMC eyengeziwe kuzokwandisa kakhulu i-viscosity. Ekukhiqizweni kwangempela, inani le-CMC elengeziwe ngokuvamile liphakathi kuka-0.5% no-3%, lilungiswa ngokuya ngezidingo ezithile.
3. Izinto ezithinta ukukhethwa kwe-CMC viscosity
Lapho ukhetha i-CMC, ezinye izici ezinomthelela zidinga ukucatshangelwa:
a. Ukwakhiwa kwe-glaze
Ukwakheka kwe-glaze kuzothinta ngqo izidingo zayo ze-viscosity. Isibonelo, ama-glaze anenani elikhulu lempushana ecolekile angadinga i-thickener ene-viscosity ephakeme ukuze kugcinwe ukumiswa okuhle. Ama-glaze anezinhlayiya ezinhle kancane angase angadingi i-viscosity ephezulu kakhulu.
b. Usayizi wezinhlayiyana ezicwebezelayo
Ama-glaze anobuhle obuphakeme adinga i-CMC ukuthi ibe nezindawo zokujiya ezingcono ukuze kuqinisekiswe ukuthi izinhlayiya ezinhle zingamiswa ngokulinganayo oketshezini. Uma i-viscosity ye-CMC inganele, impushana enhle ingase ihle, okuholela ekukhanyeni okungalingani.
c. Ukuqina kwamanzi
Ubulukhuni bamanzi bunomphumela othile ekuncibilikeni nasekujikeni kwe-CMC. Ukuba khona kwe-calcium eningi ne-magnesium ion emanzini aqinile kungase kunciphise umphumela wokujiya we-CMC futhi kubangele imvula. Uma usebenzisa amanzi aqinile, kungase kudingeke ukhethe izinhlobo ezithile ze-CMC ukuze uxazulule le nkinga.
d. Izinga lokushisa lokusebenza kanye nomswakama
Izinga lokushisa elihlukile lendawo yokusebenza kanye nomswakama kuzophinde kuthinte i-viscosity ye-CMC. Isibonelo, endaweni yokushisa ephezulu, amanzi ahwamuka ngokushesha, futhi i-CMC ene-viscosity ephansi ingase idingeke ukuze kugwenywe ukujiya ngokweqile kwe-glaze slurry. Ngokuphambene nalokho, indawo enezinga lokushisa eliphansi ingase idinge i-viscosity ephakeme ye-CMC ukuze kuqinisekiswe ukuzinza kanye nokumanzi kwe-slurry.
4. Ukukhetha okusebenzayo nokulungiswa kwe-CMC
Ekusetshenzisweni kwangempela, ukukhethwa nokulungiswa kwe-CMC kufanele kwenziwe ngokulandela lezi zinyathelo ezilandelayo:
Ukukhethwa kohlobo lwe-AnxinCel®CMC: Okokuqala, khetha uhlobo olufanele lwe-CMC. Kunamamaki ahlukene e-viscosity e-CMC emakethe, angakhethwa ngokuya ngezidingo ze-viscosity kanye nezidingo zokumiswa kwe-glaze slurry. Isibonelo, i-CMC enesisindo esiphansi se-molecular ifanele ama-glaze slurries adinga i-viscosity ephansi, kuyilapho i-CMC yesisindo se-molecular high ifanele ama-glaze slurries adinga i-viscosity ephezulu.
Ukulungiswa kokuhlolwa kwe-viscosity: Ngokuya ngezidingo ezithile ze-glaze slurry, inani le-CMC elingeziwe liyalungiswa ngokuhlolwa. Indlela evamile yokuhlola iwukwengeza kancane kancane i-CMC futhi ulinganise i-viscosity yayo kuze kube yilapho kufinyelelwa uhla lwe-viscosity olufunekayo.
Ukuqapha ukuzinza kwe-glaze slurry: I-glaze slurry elungisiwe idinga ukushiywa ukuze ime isikhathi esithile ukuze ibone ukuzinza kwayo. Hlola imvula, i-agglomeration, njll. Uma kunenkinga, inani noma uhlobo lwe-CMC kungase kudingeke ukuthi lulungiswe.
Lungisa ezinye izithasiselo: Uma usebenzisaI-CMC, kuyadingeka futhi ukucabangela ukusetshenziswa kwezinye izithasiselo, njengama-dispersants, ama-level agents, njll. Lezi zithasiselo zingase zihlanganyele ne-CMC futhi zithinte umphumela wayo wokujiya. Ngakho-ke, lapho ulungisa i-CMC, kuyadingeka futhi ukunaka isilinganiso sezinye izithasiselo.
Ukusetshenziswa kwe-CMC ku-ceramic glaze slurry kuwumsebenzi wobuchwepheshe obuphezulu, odinga ukucatshangelwa okuphelele nokulungiswa okusekelwe ezidingweni ze-viscosity, ukwakheka, usayizi wezinhlayiyana, indawo yokusebenzisa kanye nezinye izici ze-glaze slurry. Ukukhetha okunengqondo kanye nokwengezwa kwe-AnxinCel®CMC akukwazi nje ukuthuthukisa ukuzinza nokumanzi kwe-glaze slurry, kodwa futhi kuthuthukise umphumela wokugcina we-glaze. Ngakho-ke, ukuqhubeka nokwenza kahle nokulungisa indlela yokusebenzisa i-CMC ekukhiqizeni kuyisihluthulelo sokuqinisekisa ikhwalithi yemikhiqizo yobumba.
