Hauv cov txheej txheem tsim cov khoom siv ceramic, qhov viscosity ntawm cov glaze slurry yog ib qho tseem ceeb heev, uas cuam tshuam ncaj qha rau qhov fluidity, uniformity, sedimentation thiab qhov kawg glaze nyhuv ntawm glaze. Yuav kom tau txais qhov zoo tagnrho glaze nyhuv, nws yog ib qho tseem ceeb kom xaiv qhov tsim nyogCMC (Carboxymethyl Cellulose) ua ib qho thickener. CMC yog ib qho polymer compound ntuj uas feem ntau siv rau hauv cov ceramic glaze slurry, nrog cov thickening zoo, rheological zog thiab suspension.
1. Nkag siab txog qhov yuav tsum tau ua kom cov kua nplaum nplaum zoo li cas
Thaum xaiv CMC, koj yuav tsum xub piav qhia txog qhov yuav tsum tau ua kom pom tseeb ntawm cov kua nplaum glaze slurry. Cov kua nplaum sib txawv thiab cov txheej txheem tsim khoom muaj cov kev cai sib txawv rau qhov viscosity ntawm cov kua nplaum glaze slurry. Feem ntau hais lus, qhov viscosity siab dhau lossis qis dhau ntawm cov kua nplaum glaze slurry yuav cuam tshuam rau kev txau, txhuam lossis dipping ntawm cov kua nplaum.
Cov kua nplaum uas tsis muaj viscosity ntau: tsim nyog rau kev txau tshuaj. Cov viscosity tsawg dhau tuaj yeem ua kom cov kua nplaum tsis txhaws lub phom txau thaum txau tshuaj thiab tuaj yeem tsim cov txheej txheej sib xws dua.
Cov kua nplaum uas muaj viscosity nruab nrab: tsim nyog rau kev dipping. Cov viscosity nruab nrab tuaj yeem ua rau cov kua nplaum npog qhov chaw ceramic, thiab nws tsis yooj yim rau sag.
Cov kua nplaum uas muaj viscosity siab: tsim nyog rau cov txheej txheem txhuam. Cov kua nplaum uas muaj viscosity siab tuaj yeem nyob rau ntawm qhov chaw ntev, zam kev ntws ntau dhau, thiab yog li tau txais cov txheej nplaum tuab dua.
Yog li ntawd, kev xaiv CMC yuav tsum phim cov kev cai ntawm cov txheej txheem tsim khoom.
2. Kev sib raug zoo ntawm kev ua kom tuab thiab viscosity ntawm CMC
Qhov kev ua kom tuab ntawm AnxinCel®CMC feem ntau yog txiav txim siab los ntawm nws qhov hnyav molecular, qib carboxymethylation thiab qhov ntau ntxiv.
Qhov hnyav molecular: Qhov hnyav molecular ntawm CMC siab dua, nws cov nyhuv tuab dua. Qhov hnyav molecular siab dua tuaj yeem ua rau cov kua nplaum viscosity ntau dua, yog li nws tsim cov slurry tuab dua thaum siv. Yog li ntawd, yog tias xav tau cov slurry glaze viscosity siab dua, yuav tsum xaiv CMC qhov hnyav molecular siab.
Qib ntawm carboxymethylation: Qhov siab dua ntawm carboxymethylation ntawm CMC, qhov muaj zog dua nws cov dej solubility, thiab nws tuaj yeem ua tau zoo dua hauv dej los tsim cov viscosity siab dua. Cov CMCs feem ntau muaj cov degree sib txawv ntawm carboxymethylation, thiab cov hom tsim nyog tuaj yeem xaiv raws li qhov xav tau ntawm cov glaze slurry.
Ntxiv ntau npaum li cas: Qhov ntxiv ntau npaum li cas ntawm CMC yog ib txoj hauv kev ncaj qha los tswj qhov viscosity ntawm cov kua nplaum. Ntxiv CMC tsawg dua yuav ua rau qhov viscosity ntawm cov kua nplaum qis dua, thaum nce qhov ntau ntawm CMC ntxiv yuav ua rau qhov viscosity ntau dua. Hauv kev tsim khoom tiag tiag, qhov ntau ntawm CMC ntxiv feem ntau yog ntawm 0.5% thiab 3%, kho raws li qhov xav tau tshwj xeeb.
3. Tej yam uas cuam tshuam rau kev xaiv CMC viscosity
Thaum xaiv CMC, qee yam uas cuam tshuam yuav tsum tau xav txog:
a. Cov khoom xyaw ntawm cov kua nplaum
Qhov sib xyaw ua ke ntawm cov glaze yuav cuam tshuam ncaj qha rau nws cov viscosity xav tau. Piv txwv li, cov glazes uas muaj ntau cov hmoov zoo yuav xav tau cov thickener nrog viscosity siab dua kom tswj tau qhov suspension zoo. Cov glazes uas muaj cov khoom me me tsawg dua yuav tsis xav tau viscosity siab dhau.
b. Qhov loj ntawm cov khoom me me ntawm cov glaze
Cov glaze uas muaj qhov zoo dua yuav tsum tau CMC kom muaj cov khoom tuab dua kom ntseeg tau tias cov khoom me me tuaj yeem raug dai kom sib npaug hauv cov kua. Yog tias qhov viscosity ntawm CMC tsis txaus, cov hmoov zoo yuav los ua ke, ua rau cov glaze tsis sib npaug.
c. Qhov tawv ntawm dej
Qhov tawv ntawm dej muaj qee yam cuam tshuam rau qhov solubility thiab thickening ntawm CMC. Muaj ntau calcium thiab magnesium ions hauv dej tawv yuav txo qhov thickening ntawm CMC thiab txawm tias ua rau nag. Thaum siv dej tawv, koj yuav tsum xaiv qee hom CMC los daws qhov teeb meem no.
d. Ua haujlwm kub thiab av noo
Qhov kub thiab av noo sib txawv ntawm qhov chaw ua haujlwm kuj yuav cuam tshuam rau qhov viscosity ntawm CMC. Piv txwv li, nyob rau hauv qhov chaw kub siab, dej ua pa sai dua, thiab CMC-viscosity qis yuav xav tau kom tsis txhob tuab dhau ntawm cov kua nplaum. Ntawm qhov tsis sib xws, qhov chaw kub qis yuav xav tau CMC viscosity siab dua kom ntseeg tau tias cov kua nplaum ruaj khov thiab fluidity.
4. Kev xaiv thiab kev npaj CMC
Thaum siv tiag tiag, kev xaiv thiab kev npaj CMC yuav tsum tau ua raws li cov kauj ruam hauv qab no:
Xaiv hom AnxinCel®CMC: Ua ntej, xaiv hom CMC uas tsim nyog. Muaj ntau qib viscosity ntawm CMC hauv khw, uas tuaj yeem xaiv raws li qhov yuav tsum tau ua viscosity thiab cov kev cai ncua ntawm cov glaze slurry. Piv txwv li, CMC qhov hnyav molecular qis yog qhov tsim nyog rau cov glaze slurries uas xav tau viscosity qis, thaum CMC qhov hnyav molecular siab yog qhov tsim nyog rau cov glaze slurries uas xav tau viscosity siab.
Kev hloov kho qhov viscosity: Raws li qhov xav tau tshwj xeeb ntawm cov glaze slurry, qhov ntau ntawm CMC ntxiv yog hloov kho los ntawm kev sim. Txoj kev sim feem ntau yog maj mam ntxiv CMC thiab ntsuas nws cov viscosity kom txog thaum tau txais qhov ntau ntawm viscosity xav tau.
Kev saib xyuas qhov ruaj khov ntawm cov kua nplaum: Cov kua nplaum uas tau npaj tseg yuav tsum tau tso rau ib lub sijhawm kom pom nws qhov ruaj khov. Xyuas seb puas muaj nag lossis daus, sib sau ua ke, thiab lwm yam. Yog tias muaj teeb meem, qhov ntau lossis hom CMC yuav tsum tau hloov kho.
Kho lwm yam khoom ntxiv: Thaum sivCMC, nws tseem yog qhov tsim nyog los xav txog kev siv lwm yam khoom ntxiv, xws li cov tshuaj dispersants, cov neeg sawv cev leveling, thiab lwm yam. Cov khoom ntxiv no yuav cuam tshuam nrog CMC thiab cuam tshuam rau nws cov nyhuv thickening. Yog li ntawd, thaum kho CMC, nws tseem yog qhov tsim nyog yuav tsum tau them sai sai rau qhov piv ntawm lwm cov khoom ntxiv.
Kev siv CMC hauv cov khoom siv ua kom cov kua nplaum yog ib txoj haujlwm siv tshuab heev, uas yuav tsum tau xav txog thiab kho kom haum raws li qhov yuav tsum tau ua kom cov kua nplaum, cov khoom sib xyaw, qhov loj me ntawm cov khoom me me, kev siv ib puag ncig thiab lwm yam ntawm cov khoom siv ua kom cov kua nplaum. Kev xaiv thiab ntxiv AnxinCel®CMC tsim nyog tsis yog tsuas yog txhim kho qhov ruaj khov thiab kev ntws ntawm cov kua nplaum xwb, tab sis kuj txhim kho qhov txiaj ntsig ntawm cov kua nplaum kawg. Yog li ntawd, kev txhim kho tas li thiab kho cov mis siv ntawm CMC hauv kev tsim khoom yog qhov tseem ceeb rau kev ua kom zoo ntawm cov khoom siv ua kom ...
