I-Ceramic Ibanga CMC Carboxymethyl Cellulose

I-Ceramic Ibanga CMC (carboxymethyl celtuleose) ikhemikhali elibalulekile elisetshenziswe kabanzi kwinqubo yokukhiqiza ubumba. Njengezinto ze-polymer zemvelo, i-CMC iyisisulu se-cellulose, futhi isakhiwo sayo samangqamuzana iqukethe amaqembu amaningi e-carboxymethyl (-ch2cooh), okwenza kube yinhle ngamanzi futhi anamanzi amnandi. Iqhaza le-Curamic Ibanga le-CMC embonini ye-ceramic likhonjiswa ikakhulukazi ezinamatheli, ama-dispersants, abakhulu kanye nabaqinisi.

1. Izakhiwo nokwakheka kwe-CMC
I-CMC itholakala nge-carboxmetylulation ye-cellulose yemvelo. Inezici ezilandelayo:

I-Solubinity yamanzi: I-CMC ingancibilikisa ngamanzi ukwakha isixazululo ngokubona okuthile.

I-Adhesion: Ukuba khona kwamaqembu e-carboxymethyl kuma-molecule alo kukwenza ukuthi kuthuthukise amandla okubopha phakathi kwezinhlayiya, ngaleyo ndlela kuthuthukiswe amandla nokuqina kwemikhiqizo ye-ceramic.

Ukulungiswa: Ngokushintsha isisindo molecular kanye degree of carboxmethylitation of CMC, i-solubity yayo, i-viscosity nezinye izici zingalawulwa ukuze zihlangabezane nezidingo zezinqubo zokukhiqiza ze-ceramic.

2. Ukusetshenziswa kwe-CMC ekukhiqizeni kwe-ceramic
Umsebenzi we-Binder: Kulungiswa udaka lwe-ceramic, i-CMC ivame ukusetshenziswa njenge-binder. Kungakhuphula ukubonwa kodaka, okwenza kube lula ukubumbana ngesikhathi senqubo yokubumba, ukugwema ukuchitha kanye nokuqhekeka, ikakhulukazi ngesikhathi senqubo yokomisa, kungavimba ngempumelelo ukuqhekeka okubangelwa ukulahleka kwamanzi okusheshayo emikhiqizweni ye-ceramic.

Umsebenzi wokuhlupha: Enqubweni yokukhiqiza ye-Ceramic, izinto ezingavuthiwe ezifana nobumba, i-quartz, i-feldspar, njll. Ngokuvamile kudingeka zilondoloze izinga elithile lokuhlakazeka emanzini. I-CMC ingahlakaza ngempumelelo lezi zinhlayiya ezibonakalayo eziluhlaza futhi ivikele ekuxazululeni esikhaleni esinamanzi, ngaleyo ndlela iqinisekise ukufana kwe-slurry kanye nokwenza ngcono ikhwalithi yemikhiqizo ye-ceramic.

Umsebenzi omkhulu Ngokushintsha inani le-CMC elingezwe, izakhiwo ze-mbosoloji ze-slurry zingalawulwa ngokunembile, ngaleyo ndlela zisebenzise inqubo yokubumba ubumba. Ukwandisa i-viscosity kungenza futhi ukuthi ama-slurry abe nokuqina okungcono nokusebenza ngesikhathi senqubo yokubumba.

Umsebenzi weStabilizer: Ukuqina kwe-ceramic slurry kubalulekile kwikhwalithi yokubumba. I-CMC ingasiza ama-slurry alondoloze inani elizinzile le-PH nokuvuleka, avimbele ukwenzeka kwezinkinga ezinjengokuhlukaniswa kwezulu nokuvuthayo, futhi ngenxa yalokho aqinisekise ukufana kanye nokuvumelana komkhiqizo.

Umsebenzi ngesikhathi sokudubula: Ngesikhathi sokudubula kwama-ceramics, imikhiqizo yokukhohlisa ye-CMC ingasebenza njengomthombo wezinto eziphilayo ukusiza ukwakheka kwama-ceramics ngesikhathi senqubo yokudubula. Futhi kungathuthukisa ubushelelezi kanye nokulimala kwendawo ye-ceramic futhi kuthuthukise ikhwalithi yokubukeka komkhiqizo ophelile.

3. Izici ze-Curamic Ibanga CMC
Ukumsulwa okuphezulu: Ibanga le-Curamic Ibanga le-CMC lidinga ubumsulwa obuphakeme bokugwema ukungcola okuthinta ukusebenza kwemikhiqizo ye-ceramic. Ukuhlanzeka okuphezulu kwe-CMC kunganciphisa ngempumelelo ukukhiqizwa kwegesi ngesikhathi sokudubula futhi kuqinisekiswe ubuqili nobulukhuni be-ceramics.

Ubukhulu bezinhlayiyana ze-Uniform Partic: Ubukhulu be-Curamic Ibanga le-CMC buyadingeka ukuba bube umfaniswano, osiza ukuhluka kwalo nokuqina ku-ceramic slurry. I-CMC enosayizi omuhle we-Particle inganikeza imiphumela engcono yokuqina nemiphumela yokuhlakazeka.

Ukudalulwa okuhle nokunamathela: esinye isidingo esingukhiye sebanga le-ceramic Ibanga le-CMC likuhlekisa okuhle nokunamathelisa, okuthinta ngqo ukufana kanye nekhwalithi yokubumba ye-ceramic slurry.

Okuqukethwe kwe-ash okuphansi: okuqukethwe komlotha ku-Ceramic Ibanga CMC kudinga ukulawulwa ezingeni eliphansi. Okuqukethwe okuphezulu kakhulu komlotha kuzoba nomthelela omubi kwikhwalithi yokudubula yama-ceramics namandla nokubukeka komkhiqizo wokugcina.

I-4. Inqubo yokukhiqiza ye-Curamic-grade CMC
Ukukhiqizwa kwe-CERAMIC-Grade CMC kuvame ukwenziwa ngezinyathelo ezilandelayo:

Ukucutshungulwa okubonakalayo okuluhlaza: Khetha i-cellulose yemvelo ephezulu njengento eluhlaza, ukuphatha kuqala futhi ususe ukungcola.

I-Carboxmetylation reaction: Reaction cellulose nge-chloroosetic acid futhi wenze i-carboxyboxylution ngaphansi kwezimo ze-alkali ukukhiqiza i-CMC.

Ukungathathi hlangothi nokugeza: Isixazululo se-CMC ngemuva kokusabela kudinga ukuhamba ngokungathathi hlangothi, ukugeza kanye nezinye izinyathelo ukususa izinto ezisele ze-alkaline nokunye ukungcola.

Ukomisa nokuchoboza: Uketshezi we-CMC ophathwe ngomisiwe ukwakha i-powder. Ekugcineni, imininingwane edingekayo yezinhlayiyana edingekayo itholakala ngokuchoboza.

Njengezinto ezisebenzayo, i-Curamic-grade CMC inezinzuzo eziningi futhi isetshenziswa kabanzi kwizixhumanisi eziningi kwinqubo yokukhiqiza ye-ceramic. Akunakusebenza kuphela njenge-binder, dispersant, ikhudlwana kanye ne-stabilizer, kepha futhi ithuthukise ikhwalithi nokuqina kwemikhiqizo ye-ceramic. Ngokuthuthukiswa komkhakha we-ceramic, izidingo zokusebenza kwe-CMC zikhula njalo, kanye nenqubo yokukhiqiza kanye nezinkundla zohlelo lokusebenza lwe-CERAMIC-Grade CMC nazo zikhula njalo. Ngakho-ke, i-CERAMIC-Grade CMC ngokungangabazeki ingesinye sezinto ezibalulekile ekukhiqizeni ubumba, futhi idlala indima ebalulekile ekuthuthukiseni ikhwalithi yemikhiqizo ye-ceramic.
