Sodium carboxymethyl cellulose (CMC) inoita mabasa akati wandei akakosha mukugadzira makeramiki, kunyanya mukugadzira uye kuumbwa kweceramic. Heano mashandisirwo eCMC mumatanho akasiyana ekugadzirwa kweceramics:

1. Binder muCeramic Bodies: CMC inowanzoshandiswa sebhainda mumitumbi yeceramic kana greenware formulations. Ceramic powders, sevhu kana alumina, inosanganiswa nemvura uye CMC kuti iite murwi wepurasitiki unogona kuumbwa kana kuumbwa kuita mafomu anodiwa, semataira, zvidhinha, kana hari. CMC inoshanda senge bhainda renguva pfupi, yakabata maceramic particles pamwe chete panguva yekuumba uye kuomesa matanho. Iyo inopa kubatana uye plastiki kune iyo ceramic misa, ichibvumira kubata nyore uye kuumbwa kweakaomesesa maumbirwo.
2. Plasticizer uye Rheology Modifier: CMC inoshanda seplasticizer uye rheology modifier mune ceramic slurries kana slips inoshandiswa kukanda, kutsvedza kukanda, kana extrusion maitiro. CMC inovandudza kuyerera zvivakwa uye kushanda kweceramic kumiswa, kuderedza viscosity uye kuwedzera fluidity. Izvi zvinogonesa kukanda kana kuumbwa kweceramics kuita mold kana kufa, kuve nechokwadi chekuzadza yunifomu uye kushomeka kudiki muzvigadzirwa zvekupedzisira. CMC zvakare inodzivirira sedimentation kana kugadzirisa zveceramic zvimedu mukumiswa, kuchengetedza kugadzikana uye homogeneity panguva yekugadzirisa.
3. Deflocculant: Mukugadzirwa kweceramic, CMC inoita senge deflocculant kuparadzira uye kudzikamisa zvimedu zveceramic mune aqueous suspensions. CMC mamorekuru adsorb pamusoro peceramic zvimedu, achidzosera mumwe nemumwe uye kudzivirira agglomeration kana flocculation. Izvi zvinotungamira kune yakavandudzwa kupararira uye kugadzikana kugadzikana, zvichiita kuti yunifomu kugoverwa kweceramic zvimedu mune slurries kana kukanda slips. Deflocculated suspensions inoratidza zvirinani kuyerera, kuderedzwa viscosity, uye kukwidziridzwa kukanda mashandiro, zvichikonzera emhando yepamusoro ceramics ane yunifomu microstructures.
4. Binder Burnout Agent: Panguva yekupfurwa kana kunyura kweceramic greenware, CMC inoshanda senge binder burnout agent. CMC inopinda mukuwora kwekupisa kana pyrolysis patembiricha yakakwira, ichisiya masara ekabhoni anoita kuti kubviswa kwema organic binders kubva kumitumbi yeceramic. Iyi nzira, inozivikanwa sebinder burnout kana debinding, inobvisa organic components kubva kune green ceramics, kudzivirira kukanganisa kwakadai sekuputika, warping, kana porosity panguva yekupfura. CMC zvakasara zvinobatsirawo mukugadzira pore uye gasi shanduko, kusimudzira densification uye kubatanidzwa kwezvinhu zveceramic panguva yekupisa.
5. Porosity Control: CMC inogona kushandiswa kudzora porosity uye microstructure yekeramic nekufurira kuomesa kinetics uye shrinkage maitiro egreenware. Nekugadzirisa kusungirirwa kweCMC mukumiswa kweceramic, vagadziri vanogona kugadzirisa mwero wekuomeswa uye shrinkage mwero wegirinhi ceramics, optimize pore kugovera uye kuwanda mune yekupedzisira zvigadzirwa. Kudzora porosity kwakakosha pakuwana yaunoda makinika, kupisa, uye magetsi zvivakwa mumakeramiki kune chaiwo maapplication, akadai sefiltration membranes, catalyst inotsigira, kana kupisa kwemafuta.

sodium carboxymethyl cellulose (CMC) inobata basa rakakosha mukugadzira ceramics nekushanda sebhainda, plasticizer, deflocculant, binder burnout agent, uye porosity control agent. Hunhu hwayo hwakasiyana-siyana hunobatsira mukugadzirisa, kuumba, uye kunaka kweceramics, zvichiita kuti kugadzirwa kwezvigadzirwa zvepamusoro zveceramic zvine zvivakwa zvakagadzirirwa kune akasiyana maindasitiri ekushandisa.
