Carboxymethyl cellulose (CMC) yakakosha yemhando yepolymer musanganiswa iyo yakashandiswa zvakanyanya muindasitiri yeceramic. Seyakanamira inonyungudika nemvura, CMC inogona kuvandudza mashandiro eceramic zvinhu, kukurudzira kugadzikana uye kufanana panguva yekugadziriswa, uye kuwedzera kunaka kwechigadzirwa chekupedzisira.
1. Zvinhu zvakakosha zve carboxymethyl cellulose
Carboxymethyl cellulose inotorwa kubva kune cellulose, ine mvura yakanaka solubility, adhesion uye thickening zvivakwa kuburikidza nemakemikari shanduko. Iyo molecular chimiro cheCMC ine carboxyl mapoka (-COOH), iyo inoita kuti igadzire colloidal mhinduro mumvura ine yakanakisa adhesion uye rheological properties. Izvi zvinoita kuti CMC ive yekuwedzera yakakosha mukugadzirwa kweceramic.
2. Kushandisa mukugadzirwa kweceramic
2.1 Adhesive
Mukugadzira zvigadzirwa zveceramic, CMC inowanzo shandiswa seanonamira. Inogona kunyatso kusimudzira simba rekubatanidza pakati pezvimedu zvimedu uye kudzivirira kutsemuka uye deformation panguva yekuomesa uye sintering. Nekugadzirisa huwandu hweCMC yakawedzerwa, iyo rheological zvimiro zve slurry inogona kugadziridzwa kuti iite kuti ishande zvakanyanya panguva yekuumbwa.
2.2 Mukobvu
CMC ine yakanakisa thickening zvivakwa uye inogona kushandiswa kugadzirisa viscosity yeceramic slurry. Izvi zvinonyanya kukosha kune maitiro akadai sekupfapfaidza uye kudurura, izvo zvinogona kuve nechokwadi kugadzikana kweiyo slurry panguva yekushanda uye kudzivirira kunaya kana stratification. Panguva imwecheteyo, viscosity yakakodzera inogona kuvandudza fluidity ye slurry, zvichiita kuti zvive nyore kuzadza mold.
2.3 Dissperant
Mukugadzirwa kweceramic, CMC inogona zvakare kushandiswa seanoparadzira kubatsira kuparadzira zvimedu zviri muceramic mbishi zvinhu uye kudzivirira agglomeration. Kuita kwakanaka kwekuparadzira kunobatsira kuvandudza kufanana uye kuwanda kwezvigadzirwa zveceramic, nekudaro kuvandudza ma mechanic zvivakwa uye optical zvimiro zvechigadzirwa chekupedzisira.
3. Mhedzisiro yeCMC pane Ceramic Properties
Mushure mekuwedzera CMC, kuita kwezvigadzirwa zveceramic kunowanzo kuvandudzwa. Zvidzidzo zvakaratidza kuti huwandu hwakakodzera hweCMC hunogona kuvandudza zvakanyanya kusimba kwesimba uye kushanduka kwesimba rezvigadzirwa zveceramic. Mukuwedzera, kuwedzerwa kweCMC kunogonawo kugadzirisa kutsetseka kwepamusoro uye kupenya kwekeramics, zvichiita kuti chigadzirwa chekupedzisira chiwedzere kunaka.
4. Kushamwaridzana kwezvakatipoteredza kweCMC
Kuenzaniswa nemapolymer echinyakare ekugadzira, CMC, seyakasikwa polima, ine yakanaka biocompatibility uye kushamwaridzana kwezvakatipoteredza. Kushandiswa kweCMC mukugadzirwa kweceramic hakungogone kuvandudza mashandiro echigadzirwa, asi zvakare kuderedza kusvibiswa kwezvakatipoteredza uye kukuvadza kumuviri wemunhu, izvo zvinosangana nezvinodiwa zvemazuva ano kusimudzira.
Kushandiswa kwecarboxymethyl cellulose muindasitiri yeceramic kunoratidza mabasa ayo akawanda sebhainda, thickener uye dispersant. Nekugadzirisa kushandiswa kwayo, kuita uye kunaka kwezvigadzirwa zveceramic zvinogona kuvandudzwa zvakanyanya, kusimudzira kusimudzira kwakasimba kweindasitiri yekeramic. Nekudzika kwekutsvagisa uye kufambira mberi kwehunyanzvi, tarisiro yekushandiswa kweCMC mukugadzirwa kweceramic ichave yakakura.
