Zvigadzirwa zvakazara zve glaze ndizvo zvakajairwa chikamu cheiyo yemba yeceramic mataira indasitiri mumakore gumi apfuura, uye glaze pinhole defects ndiyo inonyanya kuwanda mukugadzirwa kweakazara glaze zvigadzirwa, uye zvakare ndeimwe yehurema hwekugadzira iyo yakaoma kunyatso. dzivisa, izvo zvakanangainokanganisa glaze yemhando yemhedzisiro yechigadzirwa uye mwero wakanakisa wechigadzirwa chakapedzwa. Pane zvinhu zvakawanda zvinokonzeresa hurema hwepini, zvinosanganisira kuvharika, kupenya, kugadzirwa kwemaitiro uye masisitimu ekupfura, nezvimwewo, uye kupenya kunosanganisira kupenya kuzere uye kupenya kwechiso, bepa rino rinonyanya kuongorora maitiro ekuumbwa kwechiso glaze formula pane hurema hwepinhole, inokurukura nezve hukama pakati pe flux ratio uye huwandu hwakazara mufomula ine yakakura kupfura huwandu uye hwakasiyana hwekushandisa, uye hukama pakati pekupisa tembiricha yezvinhu reshiyo uye yakazara vhoriyamu, uye inokurukura mhinduro yekukurumidza uye inoshanda kutonga uye kuderedza glaze pinhole defects.
Muedzo uyu wakapedzwa mune inozivikanwa bhizinesi receramic muQingyuan, kureba kwechoto kwaive 325m, kutenderera kwemoto kwaive 48min, tembiricha yemhete yaive 1166-1168 ° C, kupenya kwechiso kwakaiswa nekukwenya glaze, uye kupenya. yakashandiswa nenzira ye glaze ye glaze yakazara, uye nhamba yepinhole defects munzvimbo ye 400mm × 800mm yakaverengwa. Kuumbwa kwemuviri wegirinhi, kupenya kwakazara uye zvinhu zvakashandiswa kupenya zvakashandiswa muyedzo zvinoratidzwa muTafura 1.
2.1 Muedzo wepesvedzero yehuwandu hwekuyerera uye yakatsva ivhu / yakapiswa aluminium reshiyo pamapini
Chekutanga: albite 12, potassium feldspar 31, quartz 20, gasi banga pasi 10, yakapiswa aluminium 22, yakaderera tembiricha frit 3, nepheline 7, zirconium silicate 9.
A maviri-factor 3-level bvunzo yakagadzirirwa pahwaro hwekutanga sikweya, kusanganisira factor A - flux ratio, factor B - yakatsva ivhu / yakatsva aluminium ratio (quartz, gasi banga pasi, yakaderera tembiricha frit yakawanda inoramba isingachinji).
A: potassium feldspar, albite ye nepheline muchiyero che3: 1: 3, chiyero 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: Aruminiyamu yakatsva yevhu rakatsva maererano nereshiyo ye3: 5, B1 (yakapiswa aluminium / ivhu rakatsva = 19/6), B2 (yakapiswa aluminium / ivhu rakatsva = 16/11), B3 (yakapiswa aluminium / ivhu rakatsva = 13/16)
Pane zvinhu zvakawanda zvinokonzeresa kukanganisa kwepini, uye zvinonyanya kukosha kugadzirisa uye kugadzirisa fomula yekuumbwa uye kupfura kwakakura kweasina-pinhole-isina glazed glaze. Nekuwedzera kwechikamu chenepheline mumucheka we glaze, chikamu che potassium feldspar uye albite chakaderera, uye pinholes yakaratidza kuderera kwemaitiro. Nekuwedzera kwechikamu chevhu rakatsva, chikamu che calcined alumina chinoderera, uye pinholes inoratidza kuwedzera kwemaitiro, uye pamwe chete. Iyo yakawanda ivhu uye quartz zvirimo mufomula, iyo inotetepa nzvimbo isina pinhole, idiki chiyero chekushandiswa kwefomula,zvakanyanya izvo zviri mukati me nepheline uye calcined alumina, iyo yakakura kuwanda kweiyo fomula isina mapinhole, uye nehupamhi hwekushandisa kweformula.
(1) Pinholes akakamurwa kuva marudzi maviri: pasi-tembiricha pinholes uye yakakwirira-tembiricha pinholes, uye hunhu huzhinji hwepasi-tembiricha pinholes ndeiyi: nhamba yepinholes yakakura, saizi idiki, inoperekedzwa nenhamba huru yepini. kukanganisa, uye iyo imwe yepasi glaze haina kunyanya kunyura kana kudiki; Hunhu huzhinji hwemapinipini ekupisa ndeaya: huwandu hwepinhole idiki, saizi yakakura, kupisa kweprickly kushoma, kunoperekedzwa necrater defects, uye imwe-pasi-pasi glaze inorema mukunyudza inki.
(2) Pakukanganisa kwepini mukugadzirwa, zvinofanirwa kutanga kuona kana iri pinhore yekudzika-tembiricha kana yepini yekupisa, zvichienderana nemamiriro ezvinhu chaiwo, calcined alumina inosarudzwa kugadzirisa iyo yakaderera-tembiricha pinhole, uye nepheline. inosarudzwa kurapa iyo yepamusoro-yepinhole yepini.
(3) Quartz sechinhu chepamusoro-tembiricha chiri muzasi glaze formula yekuvandudza tembiricha yekukura kwe glaze uye tembiricha yakakwira viscosity haina kujeka kupfuura calcined alumina, uye iyo yakawanda quartz yemukati, idiki nzvimbo isina pinholes, iyo yakamanikana iyo scope ofkushandiswa kwefomula.
