Cov khoom lag luam glaze tag nrho yog cov khoom lag luam tseem ceeb hauv kev lag luam hauv tsev ceramic pobzeb hauv kaum xyoo dhau los, thiab glaze pinhole defects yog qhov feem ntau ntawm cov khoom lag luam glaze, thiab nws kuj yog ib qho ntawm cov khoom tsis xws luag uas nyuaj rau tag nrho. zam, uas ncaj qhacuam tshuam cov nyhuv glaze zoo ntawm cov khoom thiab tus nqi zoo heev ntawm cov khoom tiav. Muaj ntau yam uas ua rau muaj qhov tsis xws luag, nrog rau qhov khoob, glazes, cov txheej txheem ntau lawm thiab cov tshuab hluav taws xob, thiab lwm yam, thiab glazes suav nrog tag nrho glaze thiab ntsej muag glaze, daim ntawv no tsuas yog kawm txog kev cuam tshuam ntawm lub ntsej muag glaze formula muaj pes tsawg leeg ntawm pinhole defects, tham txog kev sib raug zoo ntawm flux ratio thiab tag nrho cov nyiaj nyob rau hauv cov mis nrog dav firing ntau thiab ntau yam ntawm daim ntawv thov, thiab kev sib raug zoo ntawm high kub cov ntaub ntawv ratio thiab tag nrho cov ntim, thiab sib tham txog kev daws kom sai thiab zoo tswj thiab txo glaze pinhole defects.
Qhov kev ntsuam xyuas tau ua tiav hauv lub tuam txhab paub zoo ceramic hauv Qingyuan, qhov ntev ntawm qhov cub yog 325m, lub voj voog hluav taws xob yog 48min, lub nplhaib kub yog 1166-1168 ° C, lub ntsej muag glaze tau siv los ntawm scraping glaze, thiab glaze. tau siv los ntawm txoj kev glaze rau tag nrho glaze, thiab tus naj npawb ntawm pinhole tsis xws luag hauv cheeb tsam ntawm 400mm × 800mm raug xam. Cov muaj pes tsawg leeg ntawm lub cev ntsuab, tag nrho cov glaze thiab cov khoom siv raw siv rau cov glaze siv hauv kev sim yog qhia hauv Table 1.
2.1 Kev ntsuas qhov cuam tshuam ntawm flux piv thiab hlawv av / hlawv aluminium piv rau pinholes
Thawj: albite 12, poov tshuaj feldspar 31, quartz 20, roj riam ntiaj teb 10, burnt aluminium 22, tsis kub frit 3, nepheline 7, zirconium silicate 9.
Qhov thib ob-txheej txheem 3-theem xeem yog tsim los ntawm lub hauv paus square, nrog rau qhov A - flux ratio, yam B - burnt av / burnt aluminium piv (quartz, roj riam lub ntiaj teb, tsis tshua muaj kub frit tus nqi tseem unchanged).
A: potassium feldspar, albite rau nepheline hauv qhov sib piv ntawm 3: 1: 3, qib A1 (albite / potassium feldspar / nepheline = 11/28/10), A2 (albite / potassium feldspar / nepheline = 10/25/13) , A3 (albite / potassium feldspar / nepheline = 9/22/16)
B: Burnt aluminium rau hlawv av raws li qhov piv ntawm 3: 5, B1 (hluav taws kub txhuas / hlawv av = 19/6), B2 (hluav taws kub aluminium / burnt av = 16/11), B3 (hluav taws kub aluminium / hlawv av = 13/16)
Muaj ntau ntau yam uas ua rau lub pinhole tsis xws luag, thiab nws yog ib qho tseem ceeb heev rau kev debug thiab optimize cov mis muaj pes tsawg leeg thiab dav firing ntau yam uas tsis yog-pinhole-dawb puv glazed glaze. Nrog rau qhov nce ntawm qhov kev faib ua feem ntawm nepheline nyob rau hauv lub glaze mis nyuj, qhov kev faib ua feem ntawm poov tshuaj feldspar thiab albite txo, thiab cov pinholes pom ib tug txo qis. Nrog rau qhov nce ntawm qhov kev faib ua feem ntawm cov av hlawv, qhov kev faib ua feem ntawm calcined alumina txo qis, thiab cov pinholes qhia kev nce ntxiv, thiab rov ua dua. Qhov ntau cov av thiab quartz cov ntsiab lus nyob rau hauv cov mis, qhov nqaim ntawm lub pinhole-dawb cheeb tsam, qhov me me ntawm qhov loj me.daim ntawv thov ntawm cov mis,qhov ntau cov ntsiab lus ntawm nepheline thiab calcined alumina, qhov dav ntawm cov mis tsis muaj pinholes, thiab qhov dav ntawm daim ntawv thov ntawm cov mis.
(1) Pinholes tau muab faib ua ob hom: pinholes uas tsis kub kub thiab kub kub pinholes, thiab cov yam ntxwv ntawm cov pinholes uas tsis kub kub yog: tus naj npawb ntawm pinholes yog loj, qhov loj me me, nrog rau ib tug loj tus naj npawb ntawm prickly. tsis xws luag, thiab ib qho hauv qab glaze yog qhov yooj yim tsis nqus los yog me ntsis; Cov yam ntxwv ntawm high-temperature pinholes yog: tus naj npawb ntawm pinholes yog me me, qhov loj yog loj, prickly tshav kub yog tsawg, nrog los ntawm crater defects, thiab ib leeg-hauv qab glaze yog hnyav dua nyob rau hauv tus number case nqus.
(2) Rau pinhole tsis xws luag hauv kev tsim khoom, nws yog thawj zaug uas yuav tsum tau txiav txim siab seb nws puas yog pinhole kub lossis kub pinhole, raws li qhov xwm txheej tiag tiag, calcined alumina nyiam los daws qhov kub ntawm qhov pinhole, thiab nepheline. yog nyiam los kho qhov kub-kub pinhole.
(3) Quartz raws li cov khoom kub kub hauv qab glaze formula los txhim kho qhov chaw glaze kom loj hlob kub thiab siab kub viscosity tsis tshua pom tseeb dua li calcined alumina, thiab cov ntsiab lus quartz ntau dua, thaj tsam me me tsis muaj pinholes, qhov nqaim dua. thaj tsam ntawmdaim ntawv thov ntawm tus qauv.
