Sodium carboxymethyl cellulose (CMC) yana taka muhimmiyar rawa a masana'antar yumbu, musamman a sarrafa yumbu da siffa. Anan ga yadda ake amfani da CMC a matakai daban-daban na samar da yumbu:

1. Mai ɗaure a Jikunan yumbu: CMC ana yawan amfani dashi azaman ɗaure a jikin yumbu ko ƙirar kore. Ana hada foda na yumbu, kamar yumbu ko alumina, da ruwa da CMC don samar da wani nau'in filastik wanda za'a iya siffanta shi ko a yi shi zuwa nau'ikan da ake so, kamar tayal, bulo, ko tukwane. CMC yana aiki azaman mai ɗaure na ɗan lokaci, yana riƙe da barbashi yumbu tare yayin matakan siffatawa da bushewa. Yana ba da haɗin kai da filastik zuwa ga yumbura, yana ba da izini don sauƙin sarrafawa da ƙirƙirar siffofi masu rikitarwa.
2. Plasticizer da Rheology Modifier: CMC yana aiki azaman mai yin robobi da rheology gyare-gyare a cikin yumbu slurries ko zamewa da ake amfani da su don simintin gyare-gyare, simintin gyare-gyare, ko aiwatar da extrusion. CMC yana haɓaka kaddarorin kwarara da iya aiki na dakatarwar yumbu, rage danko da haɓaka ruwa. Wannan yana sauƙaƙe simintin simintin gyare-gyare ko siffata yumbura zuwa gyare-gyare ko ya mutu, yana tabbatar da cika iri ɗaya da ƙarancin lahani a samfuran ƙarshe. CMC kuma yana hana lalatawa ko daidaita abubuwan yumbu a cikin dakatarwa, kiyaye kwanciyar hankali da daidaituwa yayin aiki.
3. Deflocculant: A cikin sarrafa yumbu, CMC yana aiki azaman mai lalata don tarwatsawa da daidaita sassan yumbu a cikin dakatarwar ruwa. Kwayoyin CMC suna cuɗawa a saman ɓangarorin yumbu, suna tunkuɗe juna kuma suna hana haɓakawa ko flocculation. Wannan yana haifar da ingantaccen tarwatsewa da kwanciyar hankali na dakatarwa, ba da damar rarraba iri ɗaya na barbashi yumbu a cikin slurries ko simintin gyare-gyare. Dakatarwar da aka lalatar tana nuna mafi kyawun ruwa, rage danko, da ingantaccen aikin simintin gyare-gyare, yana haifar da ingantattun yumbu masu inganci tare da ƙayyadaddun ƙayyadaddun tsari.
4. Wakilin Burnout Binder: Lokacin harbe-harbe ko sintiri na yumbu greenware, CMC yana aiki azaman wakili mai ƙonewa. CMC yana jurewa bazuwar thermal ko pyrolysis a yanayin zafi mai tsayi, yana barin ragowar carbonaceous wanda ke sauƙaƙe cire abubuwan da ke ɗaure kwayoyin halitta daga jikin yumbura. Wannan tsari, wanda aka sani da ƙonewa mai ɗaurewa ko ƙaddamarwa, yana kawar da abubuwan da suka shafi kwayoyin halitta daga koren yumbu, hana lahani kamar fatattaka, warping, ko porosity yayin harbi. Ragowar CMC kuma suna ba da gudummawa ga samuwar pore da haɓakar iskar gas, haɓaka haɓakawa da haɓaka kayan yumbu yayin sintering.
5. Sarrafa Porosity: Ana iya amfani da CMC don sarrafa porosity da microstructure na yumbu ta hanyar tasirin bushewar motsin motsi da haɓaka halayen kore. Ta hanyar daidaita maida hankali na CMC a cikin dakatarwar yumbu, masana'antun za su iya daidaita ƙimar bushewa da raguwar ƙimar yumbu kore, inganta rarraba pore da yawa a samfuran ƙarshe. Sarrafa porosity yana da mahimmanci don cimma abubuwan da ake buƙata na inji, zafi, da kaddarorin lantarki a cikin yumbu don takamaiman aikace-aikace, irin su membranes tacewa, tallafin mai kara kuzari, ko mai sanyaya wuta.

sodium carboxymethyl cellulose (CMC) yana taka muhimmiyar rawa a masana'antar yumbu ta hanyar yin aiki azaman mai ɗaure, filastik, deflocculant, wakili mai ƙonewa, da wakili na sarrafa porosity. Kaddarorinsa masu yawa suna ba da gudummawa ga sarrafawa, tsarawa, da ingancin yumbu, yana ba da damar samar da samfuran yumbu masu inganci tare da abubuwan da aka keɓance don aikace-aikacen masana'antu daban-daban.
