Izicelo ze-CMC ku-Ceramic Glaze

I-Ceramic glaze iyimbongolo eyingilazi esetshenziswa ezitsheni ze-ceramic ukuze zithandeke ngobuhle, ziqine, futhi zisebenze. Ikhemikhali ye-ceramic glaze iyinkimbinkimbi, futhi idinga ukulawulwa okunembile kwamapharamitha ahlukahlukene ukuthola izakhiwo ezifiselekayo. Enye yamapharamitha abalulekile i-CMC, noma ukugxiliswa kwe-micelle ebalulekile, edlala indima ebalulekile ekwakhekeni nasekuzinzeni kwecwebezelayo.

I-CMC ukuhlangana kwama-surfactants lapho ukwakheka kwama-micelles kuqala ukwenzeka. I-micelle isakhiwo esakheka lapho ama-molecule e-surfactant ehlangana ndawonye esixazululweni, enza isakhiwo esiyindilinga esinemisila ye-hydrophobic phakathi nendawo namakhanda angama-hydrophilic ngaphezulu. Ku-ceramic glaze, ama-surfactants asebenza njengama-dispersants avimbela ukulungiswa kwezinhlayiya futhi akhuthaze ukwakheka kokumiswa okuzinzile. I-CMC ye-surfactant inquma inani le-surfactant elidingekayo ukuze kugcinwe ukumiswa okuzinzile, okuphinde kuthinte ikhwalithi ye-glaze.

Enye yezinhlelo ezivame kakhulu ze-CMC ku-ceramic glaze ifana ne-disperant yezinhlayiya ze-ceramic. Izinhlayiya ze-Ceramic zinokuthambekela kokuzinza ngokushesha, okungaholela ekusabalaliseni okungalingani kanye nekhwalithi ephezulu. Ama-dispersants asiza ukuvimbela ukuzinza ngokudala amandla anyanyekayo phakathi kwezinhlayiya, ezigcina zilenga ku-glaze. I-CMC ye-dispersant inquma ubuncane bokugxilisa ingqondo obudingekayo ukuze kuzuzwe ukuhlakazeka okusebenzayo. Uma ukuhlushwa kwe-disperant kuphansi kakhulu, izinhlayiya zizohlala, futhi i-glaze izobe ingalingani. Ngakolunye uhlangothi, uma ukugxila kuphezulu kakhulu, kungabangela ukuthi i-glaze ingazinzi futhi ihlukaniswe ibe izendlalelo.

Esinye isicelo esibalulekile seI-CMC ku-ceramic glazeifana ne-rheology modifier. I-Rheology ibhekisela ocwaningweni lokugeleza kwento, futhi kucwecwe lwe-ceramic, ibhekisela endleleni i-glaze egeleza ngayo futhi ihlale endaweni yobumba. I-rheology ye-glaze ithonywa yizici ezihlukahlukene, okuhlanganisa ukusatshalaliswa kosayizi wezinhlayiyana, i-viscosity yendawo yokumisa, kanye nokugxila kanye nohlobo lwe-dispersant. I-CMC ingasetshenziselwa ukuguqula i-rheology ye-glaze ngokushintsha i-viscosity kanye nezakhiwo zokugeleza. Isibonelo, i-dispersant ye-CMC ephezulu ingakha i-glaze ewuketshezi eyengeziwe egeleza ngokushelela futhi ngokulinganayo phezu kwendawo, kuyilapho i-disperant ye-CMC ephansi ingakha ukucwebezela okukhudlwana okungagelezi kalula.

I-CMC ingasetshenziswa futhi ukulawula ukomisa nokudubula izakhiwo ze-ceramic glaze. Lapho i-glaze isetshenziswa endaweni ye-ceramic, kufanele yome ngaphambi kokuthi ivuthwe. Inqubo yokomisa ingathinteka yizici ezihlukahlukene, okuhlanganisa izinga lokushisa kanye nomswakama wendawo ezungezile, ukushuba kongqimba olucwebezelayo, nokuba khona kwama-surfactants. I-CMC ingasetshenziselwa ukuguqula izici zokumisa ze-glaze ngokushintsha ukushuba kwendawo kanye ne-viscosity yendawo elengayo. Lokhu kungasiza ekuvimbeleni ukuqhekeka, ukungqubuzana, nezinye iziphambeko ezingase zenzeke phakathi nenqubo yokomisa.

Ngokungeziwe endimeni yayo njengesilungisi se-disperant kanye ne-rheology, i-CMC ingasetshenziswa futhi njengesibophezelo ku-ceramic glaze. Izibophezelo ziyizinto ezibamba izinhlayiya ze-glaze ndawonye futhi zikhuthaze ukunamathela endaweni ye-ceramic. I-CMC ingasebenza njengesibophezelo ngokwenza ifilimu elincanyana ebusweni bezinhlayiya ze-ceramic, esiza ukuzibamba ndawonye futhi zikhuthaze ukunamathela. Inani le-CMC elidingekayo njenge-binder lincike ezintweni ezihlukahlukene, okuhlanganisa usayizi wezinhlayiyana nokuma, ukwakheka kwe-glaze, nezinga lokushisa lokudubula.

Sengiphetha, i-critical micelle concentration (CMC) idlala indima ebalulekile ekwakhiweni kwe-ceramic glaze.
