Zopangira glaze ndizomwe zimayambira pamakampani opanga matayala a ceramic m'zaka khumi zapitazi, ndipo zolakwika za glaze pinhole ndizofala kwambiri popanga zinthu zonse zowoneka bwino, komanso ndi chimodzi mwazolakwika zomwe zimakhala zovuta kuzipewa, zomwe mwachindunji.zimakhudza 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 zonyezimira zimaphatikizanso kung'anima ndi kung'anima kumaso, pepalali limayang'ana kwambiri momwe mawonekedwe amaso amawonekera paziwopsezo za pinhole, amakambirana za ubale pakati pa chiŵerengero cha flux ndi kuchuluka kwathunthu mu chilinganizo ndi kuwombera kwakukulu, chiwongolero cha kutentha ndi kusiyanasiyana kwa kutentha kwapakati ndi kuchuluka kwa kutentha kwapakati ndi kuchuluka kwa kutentha. kuwongolera mwachangu komanso mogwira mtima ndikuchepetsa kuwonongeka kwa glaze pinhole.
Chiyesocho chinamalizidwa mu bizinesi yodziwika bwino ya ceramic ku Qingyuan, kutalika kwa ng'anjo kunali 325m, kuwomberako kunali 48min, kutentha kwa mphete kunali 1166-1168 ° C, glaze ya nkhope idagwiritsidwa ntchito ndi kupukuta glaze, ndipo glaze idagwiritsidwa ntchito ndi njira yowonongeka kwa chiwerengero chonse cha 0 glaze ndi 0 glaze. × 800mm anawerengedwa. 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 / potaziyamu feldspar / nepheline = 11/28/10), A2 (albite / potassium feldspar / nepheline = 10/25/13), A3 (albite / potassium feldspar/28/10)
B: Aluminiyamu yopsereza ya nthaka yopsereza molingana ndi chiŵerengero cha 3:5, B1 (aluminiyamu yopsereza/nthaka yoyaka = 19/6), B2 (aluminiyamu wopsereza/nthaka yoyaka = 16/11), B3 (zotayidwa zopsereza/dothi loyaka = 13/16)
Pali zinthu zambiri zomwe zimayambitsa kuwonongeka kwa mapini, ndipo ndikofunikira kwambiri kukonza ndikuwongolera kapangidwe ka fomula ndi mitundu yosiyanasiyana yonyezimira 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) Ma pinholes amagawidwa m'mitundu iwiri: mapini otsika kutentha ndi mapini otentha kwambiri, ndipo makhalidwe ambiri a pinholes otsika kwambiri ndi awa: chiwerengero cha pinholes ndi chachikulu, kukula kwake ndi kakang'ono, limodzi ndi chiwerengero chachikulu cha zolakwika za prickly, ndipo glaze imodzi ya pansi imakhala yosasunthika kapena yochepa kwambiri; 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 choyamba kudziwa ngati ndi pinhole yotsika kutentha kapena nsonga yotentha kwambiri, malinga ndi momwe zilili, aluminiyamu ya calcined ndiyomwe imakonda kuthetsa chipini chotsika kwambiri, ndipo nepheline amakonda kuchiza pinhole 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 m'dera popanda pinholes, ndi yopapatiza kukula kwakugwiritsa ntchito fomula.
