CMC ua haujlwm li cas hauv kev lag luam ceramic

Hauv kev lag luam ceramic, sodium carboxymethyl cellulose (CMC) ua haujlwm ntau yam vim nws cov khoom tshwj xeeb. Nov yog li cas CMC ua haujlwm hauv kev lag luam ceramic:

1. Binder thiab Plasticizer:
   • CMC ua raws li ib tug binder thiab plasticizer nyob rau hauv ceramic lub cev los yog av nplaum formulations. Thaum tov nrog av nplaum los yog lwm yam khoom siv ceramic, CMC pab txhim kho cov yas thiab ua haujlwm ntawm cov khoom sib tov.
   • Los ntawm kev txhim kho cov khoom sib txuas ntawm cov khoom siv ceramic, CMC ua kom zoo dua qub, molding, thiab extrusion txheej txheem hauv cov khoom siv ceramic.
   • CMC kuj pab txo kev tawg thiab shrinkage thaum ziab thiab tua cov theem, ua rau muaj zog ntsuab thiab ruaj khov ntawm cov khoom siv ceramic.
2. Suspension Agent:
   • CMC ua haujlwm raws li tus neeg sawv cev ncua kev kawm nyob rau hauv ceramic slurries los yog glazes los ntawm kev tiv thaiv kev daws teeb meem ntawm cov khoom thiab tswj kev sib cais tsis sib xws.
   • Nws pab tshem tawm cov khoom siv ceramic, pigments, thiab lwm yam khoom ntxiv kom sib npaug thoob plaws hauv slurry lossis glaze, kom ntseeg tau tias daim ntawv thov thiab txheej tuab.
   • CMC txhim kho cov khoom ntws ntawm cov khoom siv hluav taws xob tsis zoo, ua kom yooj yim rau daim ntawv thov mus rau cov khoom siv ceramic thiab txhawb nqa kev tiv thaiv ib puag ncig.
3. Thickener thiab Rheology Modifier:
   • CMC ua hauj lwm raws li ib tug thickener thiab rheology hloov kho nyob rau hauv ceramic slurries, kho cov viscosity thiab ntws tus cwj pwm ntawm lub ncua kev kawm ntawv mus rau lub siab xav.
   • Los ntawm kev tswj cov rheological zog ntawm cov ceramic paste, CMC enables meej daim ntawv thov cov tswv yim xws li txhuam hniav, tshuaj tsuag, los yog dipping, ua rau txhim kho nto tiav thiab glaze uniformity.
   • CMC imparts pseudoplastic cwj pwm rau ceramic suspensions, txhais tau tias lawv viscosity txo nyob rau hauv shear stress, tso cai rau kom yooj yim daim ntawv thov thiab zoo dua nto leveling.
4. Binder rau Ceramic Fiber Khoom:
   • Hauv kev tsim cov khoom siv fiber ntau xws li cov ntaub ntawv rwb thaiv tsev thiab cov ntaub ntawv refractory, CMC yog siv los ua cov ntaub ntawv los txhim kho fiber ntau cohesion thiab tsim cov ntaub ntawv ruaj khov lossis cov laug cam.
   • CMC pab khi ceramic fibers ua ke, muab txhua yam muaj zog, yooj, thiab thermal stability rau cov khoom kawg.
   • CMC kuj pab rau kev tawg ntawm ceramic fibers nyob rau hauv lub binder matrix, kom ntseeg tau tias cov khoom sib xws thiab txhim kho kev ua tau zoo ntawm ceramic fibers.
5. Glaze Additive:
   • CMC yog ntxiv rau ceramic glazes raws li kev hloov kho viscosity thiab nplaum los txhim kho lawv daim ntawv thov zog thiab adhesion rau ceramic nto.
   • Nws pab tshem tawm cov khoom siv glaze thiab pigments, tiv thaiv kev daws teeb meem thiab ua kom muaj kev sib haum xeeb thiab kev tsim xim thaum tua.
   • CMC txhawb nqa kev sib txuas ntawm glaze thiab ceramic substrate, txo qhov tsis xws luag xws li nkag, pinholing, thiab blistering ntawm glazed nto.

Sodium carboxymethyl cellulose (CMC) ua lub luag haujlwm tseem ceeb hauv kev lag luam ceramic los ntawm kev ua cov ntaub ntawv, plasticizer, tshem tawm tus neeg sawv cev, thickener, rheology modifier, thiab glaze additive. Nws versatility thiab multifunctional zog pab txhawb rau kev ua tau zoo, txhim kho zoo, thiab txhim kho kev ua tau zoo ntawm cov khoom ceramic thoob plaws ntau theem ntawm kev tsim khoom.
