I-sodium carboxymethyl cellulose (CMC) idlala izindima ezimbalwa ezibalulekile ekukhiqizeni izitsha zobumba, ikakhulukazi ekucubunguleni nasekubunjweni kwe-ceramic.Nansi indlela i-CMC esetshenziswa ngayo ezigabeni ezahlukahlukene zokukhiqiza izitsha zobumba:

1. Isibopho Emizimbeni Yobumba: I-CMC ivamise ukusetshenziswa njengesibopho emizimbeni yobumba noma ekwenziweni kwe-greenware.Izimpushana ze-ceramic, njengobumba noma i-alumina, zixutshwa namanzi kanye ne-CMC ukuze zakhe inqwaba yepulasitiki engalolongwa noma ibunjwe ibe amafomu afiswayo, njengamathayela, izitini, noma izitsha zobumba.I-CMC isebenza njengesibophezelo sesikhashana, ibambe izinhlayiya ze-ceramic ndawonye phakathi nezigaba zokubumba nokomisa.Ihlinzeka ngokuhlangana kanye nepulasitiki kunqwaba ye-ceramic, okuvumela ukuphatha kalula kanye nokwakheka kobunjwa obuyinkimbinkimbi.
2. I-Plasticizer kanye ne-Rheology Modifier: I-CMC isebenza njenge-plasticizer ne-rheology modifier kuma-ceramic slurries noma iziliphu ezisetshenziselwa ukusakaza, ukuslip cast, noma izinqubo zokukhipha.I-CMC ithuthukisa izakhiwo zokugeleza nokusebenza kokumiswa kwe-ceramic, inciphisa i-viscosity futhi ithuthukise uketshezi.Lokhu kusiza ukubunjwa noma ukubunjwa kwezitsha zobumba zibe isikhunta noma ezifayo, okuqinisekisa ukugcwaliswa okufanayo kanye nokukhubazeka okuncane emikhiqizweni yokugcina.I-CMC iphinde ivimbele ukucwiliswa kwe-sedimentation noma ukulungiswa kwezinhlayiya ze-ceramic ekumisweni, ukugcina ukuzinza kanye ne-homogeneity ngesikhathi sokucubungula.
3. I-Deflocculant: Ekucutshungulweni kwe-ceramic, i-CMC isebenza njenge-deflocculant ukuze ihlakaze futhi izinze izinhlayiya ze-ceramic ekumisweni okumanzi.Ama-molecule e-CMC akhangisa phezu kwezinhlayiya ze-ceramic, axoshana futhi avimbele ukuhlangana noma ukugeleza.Lokhu kuholela ekuhlakazweni okuthuthukisiwe nokuzinza kokumiswa, okuvumela ukusatshalaliswa okufanayo kwezinhlayiya ze-ceramic kuma-slurries noma ama-casting slips.Ukumiswa kwe-deflocculated kubonisa uketshezi olungcono, i-viscosity encishisiwe, nokusebenza okuthuthukisiwe kokulingisa, okuholela ezitsheni zobumba zekhwalithi ephezulu ezinama-microstructures afanayo.
4. I-Binder Burnout Agent: Ngesikhathi sokudubula noma ukucwiliswa kwe-ceramic greenware, i-CMC isebenza njenge-ejenti yokushiswa kwesibopho.I-CMC iqala ukubola okushisayo noma i-pyrolysis emazingeni okushisa aphakeme, ishiya izinsalela zekhabhoni ezisiza ukususwa kwezibophezelo zezinto eziphilayo emizimbeni yobumba.Le nqubo, eyaziwa ngokuthi ukushiswa kwe-binder noma ukubopha, iqeda izakhi ze-organic kusuka ku-ceramics eluhlaza, ivimbela amaphutha njengokuqhekeka, i-warping, noma i-porosity ngesikhathi sokudubula.Izinsalela ze-CMC futhi zifaka isandla ekwakhekeni kwezimbotshana kanye nokuvela kwegesi, ezikhuthaza ukuminyana kanye nokuhlanganiswa kwezinto zobumba ngesikhathi sokushiswa.
5. Ukulawulwa Kwe-Porosity: I-CMC ingasetshenziselwa ukulawula i-porosity kanye ne-microstructure ye-ceramics ngokuthonya i-kinetics yokomisa kanye nokuziphatha kokuncipha kwe-greenware.Ngokulungisa ukugcwala kwe-CMC ekumisweni kwe-ceramic, abakhiqizi bangakwazi ukulungisa izinga lokumisa kanye nezinga lokushwabana kwezitsha zobumba eziluhlaza, bathuthukise ukusatshalaliswa kwama-pore kanye nokuminyana emikhiqizweni yokugcina.I-porosity elawulwayo ibalulekile ukuze kuzuzwe izakhiwo ezifiselekayo zomshini, ezishisayo, nezikagesi kuma-ceramics ukuze kusetshenziswe izinto ezithile, ezifana nolwelwesi lokuhlunga, izisekelo ze-catalyst, noma ukufakwa kwe-thermal.

I-sodium carboxymethyl cellulose (CMC) idlala indima ebalulekile ekwenziweni kwezitsha zobumba ngokusebenza njenge-binder, i-plasticizer, i-deflocculant, i-binder burnout agent, kanye ne-ejenti yokulawula i-porosity.Izakhiwo zayo eziguquguqukayo zinomthelela ekucutshungulweni, ekubunjweni, kanye nekhwalithi yezitsha zobumba, okuvumela ukukhiqizwa kwemikhiqizo ye-ceramic esebenza kahle enezakhiwo eziklanyelwe izinhlelo zokusebenza ezihlukahlukene zezimboni.
