Zopangira glaze ndizomwe zimayambira pamakampani opanga matayala a ceramic m'zaka khumi zapitazi, ndipo zolakwika za glaze pinhole ndizofala kwambiri popanga zinthu zonse zowuma, komanso ndi chimodzi mwazolakwika zopanga zomwe ndizovuta kuzikwaniritsa. kupewa, amene mwachindunjizimakhudza mawonekedwe a glaze wa chinthucho komanso kuchuluka kwazinthu zomalizidwa.Pali zinthu zambiri zomwe zimayambitsa kuwonongeka kwa pinhole, kuphatikiza zomwe zikusowekapo, zonyezimira, njira zopangira ndi zida zowombera, ndi zina zambiri, komanso kunyezimira kumaphatikizapo kung'anima kwathunthu ndi kung'anima kumaso. mgwirizano pakati pa chiŵerengero cha flux ndi kuchuluka kwa chiwerengero mu chilinganizo chokhala ndi kuwombera kwakukulu ndi ntchito zosiyanasiyana, ndi mgwirizano pakati pa chiŵerengero cha kutentha kwakukulu ndi voliyumu yonse, ndikukambirana njira yothetsera kulamulira mofulumira ndi kothandiza ndi kuchepetsa kuwonongeka kwa glaze pinhole.
Mayesowo adamalizidwa mu bizinesi yodziwika bwino ya ceramic ku Qingyuan, kutalika kwa ng'anjoyo kunali 325m, kuzungulira kwa kuwombera kunali 48min, kutentha kwa mphete kunali 1166-1168 ° C, glaze ya nkhope idagwiritsidwa ntchito ndikupukuta, ndi glaze. idagwiritsidwa ntchito ndi njira yonyezimira kuti ipangike, ndipo kuchuluka kwa zolakwika za pinhole m'dera la 400mm × 800mm kudawerengedwa.Mapangidwe a thupi lobiriwira, glaze wathunthu ndi zida zomwe zimagwiritsidwa ntchito poyezera zomwe zimagwiritsidwa ntchito poyesa zikuwonetsedwa mu Gulu 1.
2.1 Kuyesedwa kwa chikoka cha chiŵerengero cha flux ndi nthaka yowotchedwa / chiŵerengero cha aluminiyamu yowotchedwa pamapini
Choyambirira: albite 12, potaziyamu feldspar 31, quartz 20, mpeni wa gasi lapansi 10, aluminiyamu yoyaka 22, kutentha kwapansi 3, nepheline 7, zirconium silicate 9.
Mayeso awiri a 3-level amapangidwa pamaziko a lalikulu lapachiyambi, kuphatikizapo factor A - flux ratio, factor B - nthaka yopsereza / kuwotcha aluminium chiŵerengero (quartz, mpweya mpeni lapansi, otsika kutentha frit kuchuluka kumakhalabe kosasintha).
A: potassium feldspar, albite kwa nepheline mu chiŵerengero cha 3: 1: 3, mlingo A1 (albite / potassium feldspar / nepheline = 11/28/10), A2 (albite / potassium feldspar / nepheline = 10/25/13) , A3 (albite / potaziyamu feldspar / nepheline = 9/22/16)
B: Aluminiyamu yopsereza pa nthaka yopsereza molingana ndi chiŵerengero cha 3:5, B1 (aluminiyamu yopsereza/nthaka yoyaka = 19/6), B2 (aluminiyamu yopsereza/nthaka yoyaka = 16/11), B3 (zotayidwa zopsereza/dothi loyaka = 16/11). 13/16)
Pali zinthu zambiri zomwe zimayambitsa kuwonongeka kwa mapini, ndipo ndikofunikira kwambiri kukonza ndikuwongolera kapangidwe ka fomula ndi mitundu yosiyanasiyana yowombera yopanda mapini.Ndi kuwonjezeka kwa gawo la nepheline mu mawonekedwe a glaze, gawo la potaziyamu feldspar ndi albite linachepa, ndipo mapiniwo adawonetsa kuchepa.Ndi kuwonjezeka kwa gawo la nthaka yopsereza, gawo la aluminiyamu ya calcined limachepa, ndipo mapiniwo akuwonetsa kuchulukirachulukira, komanso mosemphanitsa.Kuchuluka kwa dothi ndi quartz mu formula, kumachepetsa malo opanda pinhole, kumachepetsakugwiritsa ntchito formula,ndipamene zili ndi nepheline ndi calcined alumina, m'pamenenso kukula kwa chilinganizocho popanda mapini, komanso kukula kwa kagwiritsidwe ntchito ka fomula.
(1) Pinholes amagawidwa m'mitundu iwiri: pinholes otsika kutentha ndi kutentha kwambiri pinholes, ndi makhalidwe ambiri a pinholes otsika kutentha ndi: chiwerengero cha pinholes ndi lalikulu, kukula kwake ndi kochepa, limodzi ndi chiwerengero chachikulu cha prickly. zolakwika, ndipo kung'anima kumodzi pansi kwenikweni sikumayamwa kapena pang'ono;Makhalidwe ambiri a pinhole zotentha kwambiri ndi izi: kuchuluka kwa ma pinholes ndi ang'onoang'ono, kukula kwake ndi kwakukulu, kutentha kwa prickly kumakhala kochepa, komwe kumayenderana ndi zolakwika za crater, ndipo glaze yapansi imodzi imakhala yolemera kwambiri pakuyamwa kwa inki.
(2) Paziwopsezo za pinhole popanga, ndikofunikira kudziwa ngati ndi pinhole yotsika kutentha kapena nsonga yotentha kwambiri, malinga ndi momwe zilili, aluminiyamu ya calcined ndiyomwe imakonda kuthana ndi pinhole yotsika kutentha, ndi nepheline. imakonda kuchiza pinbo yotentha kwambiri.
(3) Quartz monga mkulu-kutentha zakuthupi pansi glaze chilinganizo kusintha pamwamba glaze kukhwima kutentha ndi kutentha mamasukidwe akayendedwe kukhuthala ndi kutali zoonekeratu kuposa calcined aluminiyamu, ndi zambiri khwatsi zili, ang'onoang'ono dera popanda pinholes, ndi yopapatiza kuchuluka kwakugwiritsa ntchito fomula.
