Sodium carboxymethyl cellulose (CMC) imagwira ntchito zingapo zofunika popanga ziwiya zadothi, makamaka pakukonza ndi kuumba kwake. Umu ndi momwe CMC imagwiritsidwira ntchito m'magawo osiyanasiyana opanga zitsulo:

1. Binder mu Ceramic Bodies: CMC imagwiritsidwa ntchito ngati chomangira m'matupi a ceramic kapena ma greenware formulations. Ufa wa ceramic, monga dongo kapena aluminiyamu, umasakanizidwa ndi madzi ndi CMC kupanga unyinji wa pulasitiki womwe ungathe kuumbidwa kapena kupangidwa kukhala mawonekedwe ofunidwa, monga matailosi, njerwa, kapena mbiya. CMC imagwira ntchito ngati chomangira kwakanthawi, kugwirizira tinthu tating'onoting'ono ta ceramic panthawi yopangira ndi kuyanika. Amapereka mgwirizano ndi pulasitiki ku misa ya ceramic, kulola kugwidwa kosavuta ndi kupanga mawonekedwe ovuta.
2. Plasticizer ndi Rheology Modifier: CMC imagwira ntchito ngati pulasitiki ndi rheology modifier mu ceramic slurries kapena masilipi omwe amagwiritsidwa ntchito poponya, kuponyera, kapena kutulutsa. CMC imapangitsa kuyenda bwino komanso magwiridwe antchito a kuyimitsidwa kwa ceramic, kuchepetsa mamasukidwe akayendedwe komanso kupititsa patsogolo madzi. Izi zimathandizira kupanga kapena kuumba zitsulo zadothi kukhala nkhungu kapena kufa, kuwonetsetsa kudzazidwa kofanana ndi zolakwika zochepa pazomaliza. CMC komanso kupewa sedimentation kapena kukhazikika kwa ceramic particles mu suspensions, kukhala bata ndi homogeneity pa processing.
3. Deflocculant: Mu ceramic processing, CMC amachita ngati deflocculant kumwazikana ndi kukhazikika particles ceramic mu suspensions amadzimadzi. Mamolekyu a CMC amadziunjikira pamwamba pa tinthu tating'onoting'ono ta ceramic, kuthamangitsana wina ndi mnzake ndikuletsa kuphatikizika kapena kusefukira. Zimenezi zimabweretsa bwino kubalalitsidwa ndi kuyimitsidwa bata, kuwapangitsa yunifolomu kufalitsa za ceramic particles mu slurries kapena kuponyera zokopa. Kuyimitsidwa kwa deflocculated kumawoneka bwino, kuchepetsedwa kukhuthala, komanso kukhathamiritsa kwa magwiridwe antchito, zomwe zimapangitsa kuti ma ceramics apamwamba kwambiri okhala ndi ma microstructures ofanana.
4. Binder Burnout Agent: Panthawi yowotcha kapena kuwotcha greenware ya ceramic, CMC imagwira ntchito ngati chomangira moto. CMC imawonongeka ndi kutentha kapena pyrolysis pa kutentha kwakukulu, kusiya zotsalira za carbonaceous zomwe zimathandizira kuchotsa zomangira za organic ku matupi a ceramic. Izi, zomwe zimadziwika kuti binder burnout kapena debinding, zimachotsa zinthu zachilengedwe kuchokera ku zoumba zobiriwira, kuteteza zolakwika monga kusweka, kupindika, kapena porosity panthawi yowombera. Zotsalira za CMC zimathandizanso kupanga pore komanso kusinthika kwa gasi, kulimbikitsa kachulukidwe ndi kuphatikiza kwa zida za ceramic panthawi ya sintering.
5. Porosity Control: CMC itha kugwiritsidwa ntchito kuwongolera porosity ndi microstructure ya ceramic potengera kuyanika kinetics ndi shrinkage khalidwe la greenware. Posintha kuchuluka kwa CMC mu kuyimitsidwa kwa ceramic, opanga amatha kuwongolera kuchuluka kwa kuyanika komanso kuchepa kwa zoumba zobiriwira, ndikukulitsa kugawa kwa pore ndi kachulukidwe pazogulitsa zomaliza. Dongosolo lowongolera ndikofunikira kuti mukwaniritse zomwe mukufuna pamakina, matenthedwe, ndi magetsi muzoumba kuti zigwiritsidwe ntchito mwapadera, monga zosefera, zothandizira zothandizira, kapena kutchinjiriza kwamafuta.

sodium carboxymethyl cellulose (CMC) imagwira ntchito yofunika kwambiri popanga zida zadothi pogwira ntchito ngati binder, plasticizer, deflocculant, binder burnout agent, and porosity control agent. Katundu wake wosunthika amathandizira pakukonza, kupanga, ndi mtundu wa zoumba zadothi, zomwe zimapangitsa kuti apange zinthu za ceramic zogwira ntchito kwambiri zokhala ndi zida zogwirizana ndi ntchito zosiyanasiyana zamafakitale.
