Embonini yobumba,i-carboxymethyl cellulose (CMC), i-polymer compound encibilika emanzini etholakala ku-cellulose yemvelo. I-CMC isibe yisithasiselo esibalulekile enqubweni yokukhiqizwa kwemizimba eluhlaza ye-ceramic kanye nama-glaze ngenxa yokuqina kwayo okuhle kakhulu, ukubopha, ukugcinwa kwamanzi, ukumiswa kanye nezakhiwo zokulungisa i-rheological. Ithuthukisa ikhwalithi yobuso kanye namandla okusebenza kwemikhiqizo ye-ceramic ngokuthuthukisa izakhiwo ze-rheological ze-ceramic slurry kanye nezakhiwo zokwakha umzimba oluhlaza, futhi inenani elikhulu lezomnotho nelobuchwepheshe.
1. Izakhiwo eziyisisekelo ze-CMC
I-Carboxymethyl cellulose iyi-polymer encibilika emanzini e-anionic eyenziwe ngokungenisa amaqembu e-carboxymethyl (–CH₂–COOH) ku-cellulose yemvelo ngokusebenzisa ukusabela kwe-etherification. Izakhiwo zayo eziyinhloko zifaka:
Ukuncibilika okuhle: Kungancibilika ngokushesha emanzini abandayo nashisayo ukuze kwakheke isixazululo se-colloidal esibonakalayo esine-viscosity ephezulu.
Ukuqina nokulungiswa kwe-rheological: Isixazululo se-CMC sinokubukeka okukhulu futhi singalungisa i-thixotropy ye-ceramic slurry kanye ne-glaze, ukuze igcine ukuvumelana okuthile lapho imile futhi ithuthukise ukugeleza lapho kusetshenziswa amandla ashukunyiswayo noma anqunyiwe.
Ukugcinwa kwamanzi nokuzinza: I-CMC inganciphisa ngempumelelo ukuguquguquka kwamanzi odakeni nase-glaze, ithuthukise ukuzinza, futhi igweme ukuhlukaniswa noma ukuchitheka.
Ukuphepha nokuvikelwa kwemvelo: Itholakala ku-cellulose yemvelo, iyabola futhi iphephile ukuyisebenzisa.
2. Indima eyinhloko ye-CMC ekukhiqizweni kobumba
2.1. Njengesihlanzisi sodaka nesijiyisayo
Ekulungiseleleni imizimba eluhlaza ye-ceramic, i-CMC ingathuthukisa kakhulu ukugeleza kanye nezakhiwo zokumiswa kodaka. Ngokwandisa i-viscosity kanye ne-thixotropy yodaka, i-CMC isiza ekusakazeni ngokulinganayo izinhlayiya ze-ceramic, igweme imvula, futhi ikhuthaze ukuphonswa, ukufuthwa kwe-granulation noma ukushelela kwe-injection molding, ngaleyo ndlela ithuthukise ubuningi kanye nokufana komzimba oluhlaza.
2.2. Njengesithako sokubumba kanye nesinamathiseli
Ngesikhathi senqubo yokubumba ngokucindezela noma ngokukhipha, i-CMC ingathuthukisa ukuqina kwamandla okubopha komzimba oluhlaza, okwenza kube lula ukuyihlukanisa futhi kungenzeki ukuthi iqhekeke. Izakhiwo zayo ezinhle kakhulu zokubopha zingabopha ngokuqinile izinhlayiya ze-ceramic ngesikhathi senqubo yokomisa, zithuthukise amandla omile omzimba oluhlaza, futhi zinciphise ukulahlekelwa ngesikhathi senqubo yokubumba.
2.3. Thuthukisa ukusebenza kwe-glazing
Ekulungiseleleni i-glaze, i-CMC ingathuthukisa kakhulu ukumiswa nokugeleza kokuqina kwe-glaze slurry, ivimbele ukuchitheka kanye nokuhlangana. Ngaphezu kwalokho, i-CMC ilungisa i-thixotropy ye-glaze slurry, yenza inqubo ye-glazing ifane kakhulu, inciphise ukugoba, futhi ithuthukise ukuphela kobuso be-glaze layer.
2.4. Ukugcinwa kwamanzi kanye nokumelana nokuqhekeka
I-CMC ingavala ngempumelelo umswakama odakeni kanye ne-glaze, yehlise ijubane lokoma, futhi inciphise ingozi yokuqhekeka nokugoba ebusweni bomzimba. Lokhu kubaluleke kakhulu emikhiqizweni yobumba enkulu noma enodonga oluncane, okusiza ukuthuthukisa izinga lokufaneleka komkhiqizo.
2.5. Thuthukisa ikhwalithi yomkhiqizo
Ngokuthuthukisa ukusatshalaliswa kwezinhlayiya zomzimba kanye nokufana kwe-glazing, i-CMC yenza ubuso bemikhiqizo ye-ceramic evuthayo bube buthambile futhi bube buthakathaka, kuyilapho kunciphisa ukuvela kweziphambeko ezifana nezimbobo ze-pin kanye nama-bubble.
3. Ukusetshenziswa kwe-CMC ezinqubweni ezahlukene zobumba
Izinto zobumba zansuku zonke: zithuthukisa ukugeleza kodaka kanye namandla omzimba, futhi zinciphise ukuguquguquka kanye nokuqhekeka ngesikhathi sokomisa nokushisa.
Ukwakha izinto zobumba (amathayili e-ceramic, amathayili odonga, amathayili aphansi): Thuthukisa ukufana kwe-glazing kanye nekhwalithi ye-glaze, futhi wandise izinga lokukhiqiza.
Izitsha zobumba ezikhethekile: Ekukhiqizweni kwezitsha zobumba zobuchwepheshe obuphezulu njengezinto zobumba ze-elekthronikhi kanye nezinto zobumba ezisebenzayo, i-CMC isetshenziselwa ukulawula ukusatshalaliswa kwezinhlayiya nokuthuthukisa amandla aluhlaza.
Ukuphrinta kwe-ceramic 3D: Njengomlawuli we-rheological kanye ne-binder, kusiza ukuthola i-slurry viscosity efanele kanye nokunemba kokuphrinta.
4. Izici ezithinta umphumela we-CMC
Izinga lokushintshaniswa (DS): Izinga lokushintshaniswa kwe-carboxymethyl kuma-molecule e-CMC ngokuvamile liphakathi kuka-0.6–1.2. Uma i-DS iphakeme, kulapho ukuncibilika kwamanzi kanye nekhono lokujiya le-CMC liba ngcono khona.
Isisindo sama-molecule kanye nokuthamba: Ukuthamba okuphezulu kwe-CMC kunikeza ukugcinwa kwamanzi okuqinile kanye nemiphumela yokujiya, kodwa kungabangela ukugeleza koketshezi kunciphe; ibanga elifanele lidinga ukukhethwa ngokuya ngezidingo zenqubo.
Inani lokwengeza: Inani lokwengeza le-CMC ekukhiqizweni kwe-ceramic okujwayelekile lingu-0.1–0.5% wesisindo se-slurry, okudingeka lithuthukiswe ngokusebenzisa izivivinyo.
Indlela yokuncibilikisa nokusabalalisa: I-CMC idinga ukuncibilikiswa ngokuphelele ngokuxubha kakhulu kuqala ukuze kugwenywe ukuhlangana ukuze kufezwe umphumela omuhle kakhulu.
5. Izinzuzo zemvelo nezomnotho
I-CMC itholakala ku-cellulose yemvelo, inokubola okuhle kakhulu kanye nokuphepha, futhi ihlangabezana nezidingo zokuvikela imvelo eziluhlaza embonini yesimanje ye-ceramic. Ngaphezu kwalokho, umphumela wokwengeza osebenza kahle kakhulu we-CMC unganciphisa ukusetshenziswa kwamandla, unciphise isikhathi sokomisa futhi unciphise izinga lokungcola, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nezinzuzo zomnotho.
Embonini yobumba,I-CMC (i-carboxymethyl cellulose) iyisengezo esibalulekile esisebenzayo. Kusiza imikhiqizo yobumba ukufeza ikhwalithi ephezulu kanye nokusebenza kahle kokukhiqiza okuphezulu ngokuthuthukisa izakhiwo ze-rheological zodaka kanye ne-glaze, ukuthuthukisa amandla okubopha kanye namandla okomile omzimba, kanye nokwenza ngcono umphumela we-glazing. Njengoba imboni yobumba iphishekela ukuvikelwa kwemvelo okuluhlaza kanye nokukhiqizwa kokusebenza okuphezulu, amathuba okusetshenziswa kwe-CMC azoba maningi.
