Cov teebmeem ntawm Sodium Carboxymethyl cellulose ntawm Kev Ua Haujlwm ntawm Ceramic Slurry

Sodium carboxymethyl cellulose (CMC) feem ntau yog siv hauv cov slurries ceramic los txhim kho lawv cov kev ua tau zoo thiab kev ua haujlwm. Nov yog qee qhov teebmeem ntawm sodium carboxymethyl cellulose ntawm kev ua haujlwm ntawm ceramic slurry:

1. viscosity tswj:
   • CMC ua raws li kev hloov kho rheology hauv ceramic slurries, tswj lawv cov viscosity thiab ntws zog. Los ntawm kev kho qhov concentration ntawm CMC, manufacturers tuaj yeem kho qhov viscosity ntawm slurry kom ua tau raws li qhov xav tau daim ntawv thov txoj kev thiab txheej thickness.
2. Suspension ntawm Particles:
   • CMC pab tshem tawm thiab xa tawm cov khoom siv hluav taws xob sib npaug sib npaug thoob plaws hauv slurry, tiv thaiv kev teeb tsa lossis sedimentation. Qhov no ua kom muaj kev sib haum xeeb hauv kev sib xyaw thiab kev faib khoom ntawm cov khoom siv, ua rau cov txheej txheem sib xws thiab qhov zoo ntawm cov khoom siv ceramic.
3. Thixotropic Properties:
   • CMC imparts thixotropic cwj pwm rau ceramic slurries, txhais tau hais tias lawv viscosity txo nyob rau hauv shear stress (piv txwv li, nplawm los yog daim ntawv thov) thiab nce thaum muaj kev ntxhov siab raug tshem tawm. Cov cuab yeej no txhim kho qhov ntws thiab kis tau ntawm cov slurry thaum lub sij hawm thov thaum tiv thaiv sagging los yog dripping tom qab daim ntawv thov.
4. Binder thiab Adhesion Enhancement:
   • CMC ua raws li ib tug binder nyob rau hauv ceramic slurries, txhawb adhesion ntawm ceramic hais thiab substrate nto. Nws tsim ib zaj duab xis nyias, cohesive rau saum npoo, txhim kho kev sib raug zoo ntawm lub zog thiab txo qhov kev pheej hmoo ntawm kev tsis xws luag xws li tawg lossis delamination hauv cov khoom siv hluav taws xob raug rho tawm haujlwm.
5. Kev tuav dej:
   • CMC muaj cov khoom tuav dej zoo, uas pab tswj cov dej noo ntawm cov slurries ceramic thaum khaws cia thiab siv. Qhov no tiv thaiv kom qhuav tawm thiab ntxov ntxov ntawm slurry, tso cai rau lub sij hawm ua hauj lwm ntev thiab zoo adhesion rau substrate nto.
6. Green Strength Enhancement:
   • CMC pab txhawb rau lub zog ntsuab ntawm lub cev ceramic tsim los ntawm slurries los ntawm kev txhim kho particle packing thiab interparticle bonding. Qhov no ua rau muaj zog thiab muaj zog dua greenware, txo qhov kev pheej hmoo ntawm kev tawg lossis deformation thaum tuav thiab ua.
7. Kev txo qis:
   • Los ntawm kev txhim kho viscosity tswj, tshem tawm cov khoom, cov khoom sib khi, thiab lub zog ntsuab, CMC pab txo qhov tsis xws luag xws li tawg, warping, lossis deg imperfections hauv cov khoom siv ceramic. Qhov no ua rau cov khoom tiav zoo dua nrog cov khoom siv kho kom zoo thiab zoo nkauj.
8. Txhim kho kev ua tau zoo:
   • CMC txhim kho cov txheej txheem ntawm cov slurries ceramic los ntawm kev txhim kho lawv cov khoom ntws, ua haujlwm tau zoo, thiab ruaj khov. Qhov no ua rau yooj yim tuav, shaping, thiab tsim cov ceramic lub cev, nrog rau ntau txheej txheej thiab deposition ntawm ceramic txheej.

sodium carboxymethyl cellulose (CMC) ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm cov slurries los ntawm kev muab viscosity tswj, tshem tawm cov khoom, thixotropic zog, binder thiab adhesion li, dej tuav, ntsuab zog txhim kho, tsis xws luag, thiab txhim kho processability. Nws siv txhim kho kev ua tau zoo, sib xws, thiab zoo ntawm cov txheej txheem tsim cov khoom siv ceramic, ua rau kev tsim cov khoom lag luam ceramic rau ntau yam kev siv.
