Qhov cuam tshuam ntawm Carboxymethyl Cellulose (CMC) ntawm Cov Khoom Ntawm Ceramic Slurry

Carboxymethyl cellulose (CMC) yog cov dej-soluble polymer muab los ntawm cellulose uas muaj ntau yam kev siv hauv ntau yam lag luam. Hauv kev lag luam ceramics, CMC feem ntau yog siv los ua ib qho kev sib khi thiab rheology hloov kho hauv ceramic slurry formulations. Qhov sib ntxiv ntawm CMC tuaj yeem cuam tshuam rau cov khoom ntawm ceramic slurry, nrog rau nws cov viscosity, rheological cwj pwm, thiab stability. Hauv tsab xov xwm no, peb yuav tham txog qhov cuam tshuam ntawm CMC ntawm cov khoom ntawm ceramic slurry.

viscosity

Qhov sib ntxiv ntawm CMC rau ceramic slurry tuaj yeem ua rau nws cov viscosity nce. Qhov no yog vim qhov hnyav molecular thiab qib siab ntawm kev hloov pauv ntawm CMC, uas ua rau muaj viscosity siab txawm tias tsis tshua muaj siab. CMC ua raws li tus neeg sawv cev thickening, ua kom cov viscosity ntawm cov ceramic slurry thiab txhim kho nws lub peev xwm los ua raws li qhov chaw ntawm lub cev ceramic.

Rheological cwj pwm

CMC tseem tuaj yeem cuam tshuam tus cwj pwm rheological ntawm ceramic slurry. Lub rheology ntawm ceramic slurry yog ib qho tseem ceeb rau nws cov kev ua thiab kev ua tau zoo. Qhov sib ntxiv ntawm CMC tuaj yeem ua rau tus cwj pwm shear-thinning, qhov twg cov viscosity ntawm slurry txo qis raws li tus nqi shear nce. Qhov no tuaj yeem ua tau zoo rau kev ua, vim nws tso cai rau cov slurry ntws yooj yim dua thaum lub sij hawm casting, molding, los yog txheej. Tus cwj pwm rheological ntawm slurry kuj tuaj yeem cuam tshuam los ntawm qhov concentration, molecular hnyav, thiab qib ntawm kev hloov ntawm CMC.

Kev ruaj ntseg

CMC tuaj yeem txhim kho kev ruaj ntseg ntawm ceramic slurry los ntawm kev tiv thaiv kev sib cais lossis kev sib cais ntawm cov khoom. Qhov sib ntxiv ntawm CMC tuaj yeem tsim qhov kev ncua ruaj khov los ntawm kev ua kom lub viscosity ntawm slurry, txhim kho nws lub peev xwm los tuav cov khoom hauv kev ncua. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov ntawv thov uas cov slurry yuav tsum tau khaws cia lossis thauj mus deb, vim tias kev sib cais lossis kev sib cais tuaj yeem ua rau cov txheej tsis sib xws lossis tsis sib xws.

Kev sib haum xeeb

Kev sib raug zoo ntawm CMC nrog rau lwm cov khoom ntawm ceramic slurry kuj yog ib qho tseem ceeb rau kev txiav txim siab. CMC tuaj yeem cuam tshuam nrog lwm yam khoom, xws li av nplaum, feldspars, thiab lwm yam binders, cuam tshuam rau lawv cov khoom thiab kev ua haujlwm. Piv txwv li, qhov sib ntxiv ntawm CMC tuaj yeem txhim kho cov khoom sib txuas ntawm cov av nplaum, ua rau lub cev muaj zog thiab ruaj khov dua. Txawm li cas los xij, ntau dhau ntawm CMC tuaj yeem ua rau cov slurry tuab heev, ua rau muaj kev nyuaj hauv kev ua haujlwm thiab kev thov.

Noj

Qhov ntau npaum ntawm CMC hauv ceramic slurry yog ib qho tseem ceeb uas yuav tau xav txog. Qhov ntau npaum li cas ntawm CMC yuav nyob ntawm seb daim ntawv thov tshwj xeeb, nrog rau cov khoom ntawm cov slurry thiab qhov xav tau kev ua haujlwm. Feem ntau, qhov concentration ntawm CMC hauv ceramic slurry tuaj yeem nyob ntawm 0.1% mus rau 1%, nyob ntawm daim ntawv thov. Qhov siab dua ntawm CMC tuaj yeem ua rau cov slurry thicker thiab ruaj khov, tab sis kuj tuaj yeem ua rau muaj teeb meem hauv kev ua thiab daim ntawv thov.

Xaus

Hauv cov ntsiab lus, CMC tuaj yeem cuam tshuam cov khoom ntawm ceramic slurry, nrog rau nws cov viscosity, rheological cwj pwm, stability, compatibility, thiab ntau npaum. Los ntawm kev nkag siab txog kev cuam tshuam ntawm CMC ntawm cov khoom no, nws muaj peev xwm ua kom zoo dua qhov kev ua tau zoo ntawm ceramic slurry rau ntau yam kev siv, xws li casting, molding, txheej, lossis luam ntawv. Kev siv CMC hauv ceramic slurry formulations tuaj yeem ua rau kev txhim kho, kev ua tau zoo, thiab ua haujlwm ntev ntawm cov khoom siv ceramic.
