Umthelela weCarboxymethyl Cellulose (CMC) kwizakhiwo zeCeramic Slurry

I-Carboxymethyl cellulose (CMC) i-polymer encibilika emanzini etholakala ku-cellulose enohlu olubanzi lwezinhlelo zokusebenza ezimbonini ezihlukahlukene. Embonini ye-ceramics, i-CMC ivame ukusetshenziswa njenge-binder ne-rheology modifier ekwakhiweni kwe-ceramic slurry. Ukwengezwa kwe-CMC kungathinta kakhulu izakhiwo ze-ceramic slurry, kufaka phakathi i-viscosity yayo, ukuziphatha kwe-rheological, nokuzinza. Kulesi sihloko, sizoxoxa ngethonya le-CMC kuzakhiwo ze-ceramic slurry.

I-Viscosity

Ukwengezwa kwe-CMC ku-ceramic slurry kungakhuphula kakhulu i-viscosity yayo. Lokhu kungenxa yesisindo samangqamuzana aphezulu kanye nezinga eliphezulu lokushintshwa kwe-CMC, okuholela ekubonakaleni okuphezulu ngisho nasezintweni eziphansi. I-CMC isebenza njenge-ejenti yokuqina, ikhulisa i-viscosity ye-ceramic slurry futhi ithuthukise ikhono layo lokunamathela ebusweni bomzimba we-ceramic.

Ukuziphatha Kwe-Rheological

I-CMC ingaphinde ibe nomthelela ekuziphatheni kwe-rheological ye-ceramic slurry. I-rheology ye-ceramic slurry ibalulekile ekusebenzeni kwayo nokusebenza kwayo. Ukwengezwa kwe-CMC kungaholela ekuziphatheni kokunciphisa i-shear, lapho i-viscosity ye-slurry iyancipha njengoba izinga lokugunda likhuphuka. Lokhu kungaba yinzuzo ekucutshungulweni, njengoba kuvumela i-slurry ukuthi igeleze kalula ngesikhathi sokubunjwa, ukubunjwa, noma ukumbozwa. Ukuziphatha kwe-rheological kwe-slurry kungathonywa futhi ukugxilisa ingqondo, isisindo samangqamuzana, kanye nezinga lokushintshwa kwe-CMC.

Ukuzinza

I-CMC ingathuthukisa ukuzinza kwe-ceramic slurry ngokuvimbela ukuhlaliswa noma ukuhlukaniswa kwezinhlayiya. Ukwengezwa kwe-CMC kungakha ukumiswa okuzinzile ngokwandisa i-viscosity ye-slurry, ukuthuthukisa ikhono layo lokubamba izinhlayiya ekumisweni. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho i-slurry idinga ukugcinwa noma ukuthuthwa amabanga amade, njengoba ukuhlaliswa noma ukuhlukaniswa kungase kubangele ukumbozwa okungajwayelekile noma ukudubula okungaguquki.

Ukuhambisana

Ukuhambisana kwe-CMC nezinye izingxenye ze-ceramic slurry nakho kubalulekile ukucatshangelwa. I-CMC ingasebenzisana nezinye izakhi, njengobumba, i-feldspars, nezinye izibophezelo, ezithinta izakhiwo nokusebenza kwazo. Isibonelo, ukungezwa kwe-CMC kungathuthukisa izakhiwo ezibophayo zobumba, okuholela emizimbeni ye-ceramic enamandla futhi ehlala isikhathi eside. Kodwa-ke, amanani eqile e-CMC angaholela ekudakaleni okukhulu, okuholela ebunzimeni ekucutshungulweni nasekusetshenzisweni.

Umthamo

Umthamo we-CMC ku-ceramic slurry iyisici esibalulekile okufanele sicatshangelwe. Umthamo omkhulu we-CMC uzoncika kuhlelo lokusebenza oluthile, kanye nezakhiwo ze-slurry kanye nokusebenza okufunayo. Ngokuvamile, ukugxila kwe-CMC ku-ceramic slurry kungaba kusuka ku-0.1% kuya ku-1%, kuye ngokuthi isicelo. Ukugxila okuphezulu kwe-CMC kungabangela udaka oluqinile futhi oluzinzile, kodwa futhi kungaholela ebunzimeni ekucutshungulweni nasekusetshenzisweni.

Isiphetho

Kafushane, i-CMC ingaba nomthelela omkhulu ezimpahleni ze-ceramic slurry, kufaka phakathi i-viscosity yayo, ukuziphatha kwe-rheological, ukuzinza, ukuhambisana, kanye nomthamo. Ngokuqonda umthelela we-CMC kulezi zakhiwo, kungenzeka ukwandisa ukusebenza kwe-ceramic slurry yezinhlelo zokusebenza ezahlukahlukene, njengokubunjwa, ukubumba, ukumboza, noma ukuphrinta. Ukusetshenziswa kwe-CMC ekwakhekeni kwe-ceramic slurry kungaholela ekucutshungulweni okuthuthukisiwe, ukusebenza, nokuqina kwemikhiqizo yobumba.
