Muaj txheej txheem glazing hauv kev tsim cov khoom siv ceramic. Qhov hu ua glazing yog hais txog kev siv cov cua compressed los tsuag ib qho nyiaj ntawm glaze slurry rau saum npoo ntawm lub cev, uas yog, glaze tshem tawm hauv dej. Lub cev dawb paug sai sai absorbs cov dej noo nyob rau hauv ntub glaze, tsim ib tug tej yam nyuaj nto, thiab ua ib tug 300-400 micron tuab glaze txheej nyob rau saum npoo ntawm cov khoom raug rho tawm haujlwm. Txawm li cas los xij, ntau cov khoom siv ceramic shrink lub glaze thaum tso tawm, uas yog, glaze rau saum npoo ntawm cov khoom ceramic yog ploj lawm hauv cheeb tsam loj. Yuav ua li cas tiv thaiv glaze shrinkage thaum lub sij hawm tsim ceramic?
1. Ua tib zoo ntxuav cov khoom ua ntej txau glaze kom paub tseeb tias cov khoom yog du thiab huv si;
2. Txau daim ntaub ntsuab nrog dej ua ntej glazing, uas yuav pab sib tov cov av seem thiab soluble ntsev ntawm qhov chaw dawb huv ntawm glaze, tab sis yog tias qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob tshuaj tsuag dej;
3. Khaws cov qauv thiab hauv pem teb kom huv si nrog cov av nplaum ntsev tsawg. BaC03 yuav tsum tau muab tshem tawm tom qab siv dua
4. Tsis txhob siv roj lossis roj lubricating ntawm qhov qub. Thaum ntxuav lub cev dawb paug ua ntej txau glaze, compressed cua yuav raug coj mus rau hauv cov roj, yog li cov cua compressed yuav tsum lim cov roj;
5. Tsis txhob kov lossis txhuam cov glaze tom qab txau;
6. Kev siv cov khoom siv micron zoo tuaj yeem txo qhov ceev ntawm glaze dej infiltration rau hauv lub cev. Thaum lub glaze nyob rau saum npoo ntawm lub cev yog qhuav, lub qhuav shrinkage yog loj thiab nws yog ib qho yooj yim rau tawg. Cov av nplaum ntxiv rau hauv glaze yuav tsum tsis pub tshaj 5 feem pua.
