Pinholes sawv cev rau qhov zoo tshaj plaws zais qhov tsis xws luag hauv cov khoom siv huv si ceramic. Txawm hais tias me me, lawv tuaj yeem ua rau muaj teeb meem loj tom qab siv ntev. Peb lub Hoobkas tau txheeb xyuas cov hauv paus ntsiab lus ntawm cov pinholes thiab tsim cov kev daws teeb meem kom tshem tawm qhov teeb meem no.
1. Cov mis tsis tsim nyog lub cevKev daws: Kho lub cev mis kom ntseeg tau tias nws cov viscosity ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem ntau lawm.
2. Cov ntsiab lus ntau dhau ntawm cov organic thiab siab -decomposition- kub sulfates hauv lub cev thiab cov qauv glaze, uas tsim cov roj ntau ntau thaum cov tshuaj tiv thaiv thiab ua rau cov pinholes.Kev daws: Txo cov ntsiab lus sulfate hauv cov qauv kom ua kom zoo dua lawv cov kev tshawb fawb rationality.
3. Ntau dhau zoo glaze slurry haisuas impede gas tso thaum tua.Kev daws: Tsim nyog nce qhov me me ntawm glaze slurry.
4. Rushed plam casting ua haujlwm, uas tawm lub sij hawm tsis txaus rau cov roj hauv cov slurry kom dim, los yog overheated slurry uas ua rau fermentation.Kev daws: Do cov slurry maj mam ua ntej casting kom tshem tawm cov npuas npuas.
5. Tsis tshua muaj qhov pib melting kub ntawm qhov chaw glaze, uas ua rau ntau dhau daim ntawv thov glaze.Kev daws: nruj me ntsis tswj qhov pib melting kub ntawm qhov chaw glaze ntawm950 degree.
6. Tsis tsim nyog glaze txheej thickness. Kev daws: Xyuas kom cov glaze txheej thickness yog nyob rau hauv tus txheej txheem ntau yam thaum tswj qhov yuav tsum tau kev ua tau zoo ntawm glaze slurry.
7. Qhov kub thiab txias tsis tsim nyoguas hinders du gas emission los ntawm lub cev ceramic.Kev daws: Optimize qhov hluav taws xob nkhaus thiab txuas ntxiv cov pa roj theem.
