Yuav Siv CMC li cas los daws nrog Pinholes ntawm Ceramic Glaze

Pinholes ntawm ceramic glaze nto tuaj yeem yog ib qho teeb meem tshwm sim thaum lub sij hawm tua hluav taws, ua rau muaj kev zoo nkauj thiab cuam tshuam qhov zoo ntawm cov khoom siv ceramic tiav.Carboxymethyl cellulose (CMC)tuaj yeem siv los ua kev daws teeb meem los daws cov pinholes thiab txhim kho qhov zoo ntawm ceramic glazes. Nov yog yuav ua li cas siv CMC kom zoo:

1. Formulation ntawm Glaze Suspension:

• Thickening Agent: Siv CMC ua tus neeg sawv cev thickening nyob rau hauv formulation ntawm ceramic glaze suspensions. CMC pab tswj cov rheology ntawm glaze, kom ntseeg tau tias raug tshem tawm ntawm cov khoom thiab tiv thaiv kev daws teeb meem thaum khaws cia thiab daim ntawv thov.
• Binder: Koom nrog CMC rau hauv daim ntawv qhia glaze raws li ib tug binder los txhim kho adhesion thiab cohesion ntawm glaze hais nyob rau hauv ceramic nto, txo qhov tshwm sim ntawm pinhole tsim thaum lub sij hawm firing.

2. Daim Ntawv Thov:

• Txhuam lossis Txau: Siv CMC-muaj glaze rau saum npoo ceramic siv txhuam los yog tshuaj tsuag. Ua kom muaj kev tiv thaiv ib puag ncig thiab zam kev siv ntau dhau los txo qhov kev pheej hmoo ntawm kev tsim pinhole.
• Ntau Txheej: Siv ntau txheej nyias ntawm glaze es tsis yog ib txheej tuab. Qhov no tso cai rau kev tswj kom zoo dua glaze thickness thiab txo qhov kev pheej hmoo ntawm cov npuas npuas los yog cov tshuaj tsis haum rau cov pinholes.

3. Firing Cycle Optimization:

• Hluav Taws Kub Kub thiab Huab Cua: Kho qhov hluav taws kub kub thiab cua kom ua kom zoo dua qhov glaze-melt ntws thiab txo qhov tsim ntawm pinholes. Kev sim nrog ntau lub sijhawm tua hluav taws kom ua tiav qhov xav tau glaze kom loj hlob yam tsis muaj hluav taws xob ntau dhau lossis qis dua.
• Slow Cooling Rate: Ua kom qis qis qis thaum lub caij txias ntawm lub voj voog hluav taws xob. Kev txias nrawm tuaj yeem ua rau thermal poob siab thiab tsim cov pinholes raws li cov pa roj tso rau hauv lub glaze sim khiav tawm.

4. Glaze Composition Kho:

• Deflocculation: Siv CMC ua ke nrog cov tshuaj deflocculating los txhim kho particle dispersion thiab txo agglomeration nyob rau hauv lub glaze ncua kev kawm ntawv. Qhov no txhawb lub smoother glaze nto thiab txo qhov tshwm sim ntawm pinholes.
• Kev txo qis ntawm impurities: xyuas kom meej tias cov ntaub ntawv glaze yog dawb los ntawm impurities uas tuaj yeem ua rau kev tsim pinhole. Siv cov khoom zoo raw khoom thiab ua kom zoo sib xyaw thiab sieving kom tshem tawm cov kab mob.

5. Kev Ntsuas thiab Kev Ntsuas:

• Test Vuas: Tsim cov vuas los yog cov qauv qauv los ntsuas qhov kev ua tau zoo ntawm CMC-muaj glazes nyob rau hauv qhov sib txawv tua. Ntsuas qhov zoo ntawm qhov chaw, glaze adhesion, thiab pinhole tshwm sim txhawm rau txheeb xyuas cov qauv kev pom zoo thiab kev tua hluav taws.
• Kev hloov kho thiab kev ua kom zoo: Raws li cov txiaj ntsig ntawm kev sim, ua qhov tsim nyog hloov kho rau glaze compositions, daim ntawv thov cov txheej txheem, los yog firing teem sij hawm kom optimize pinhole txo thiab ua tiav cov yam ntxwv saum npoo.

6. Kev txiav txim siab txog kev nyab xeeb thiab ib puag ncig:

• Regulatory Compliance: Xyuas kom meej tias kev sivCMC nyob rau hauv ceramic glazesua raws li cov qauv kev nyab xeeb thiab kev tswj hwm rau kev sib cuag zaub mov, kev noj qab haus huv kev ua haujlwm, thiab kev tiv thaiv ib puag ncig.
• Kev Tswj Pov Hwm: Pov tseg cov khoom siv glaze uas tsis siv thiab cov khoom pov tseg raws li cov kev cai hauv zos thiab cov kev coj ua zoo tshaj plaws rau kev tuav cov khoom phom sij lossis cov teeb meem.

Los ntawm kev sib koom ua ke CMC rau hauv cov txheej txheem ceramic glaze thiab ua tib zoo tswj cov txheej txheem kev siv thiab kev tua hluav taws, nws muaj peev xwm txo qis qhov tshwm sim ntawm pinholes thiab ua tiav cov khoom zoo, tsis muaj qhov tsis xws luag ntawm cov khoom siv ceramic. Kev sim, kev sim, thiab kev saib xyuas kom meej yog qhov tseem ceeb rau kev siv CMC kom txo tau pinhole hauv ceramic glazes.
