Imikhiqizo ecwebezelayo egcwele iyisigaba esijwayelekile semboni yasekhaya yamathayela e-ceramic eminyakeni eyishumi edlule, futhi ukukhubazeka kwe-glaze pinhole yikona okuvame kakhulu ekukhiqizeni imikhiqizo ecwebezelayo egcwele, futhi kungenye yamaphutha okukhiqiza okunzima ukuwenza ngokuphelele. gwema, okuyinto ngqoithinta umphumela wekhwalithi ye-glaze yomkhiqizo kanye nezinga elihle kakhulu lomkhiqizo oqediwe.Kunezici eziningi ezibangela ukukhubazeka kwe-pinhole, okuhlanganisa izikhala, ukucwebezela, imingcele yenqubo yokukhiqiza nezinhlelo zokudubula, njll., kanye nokucwebezela kuhlanganisa ukucwebezela okugcwele nokucwebezela kobuso, leli phepha lihlola ikakhulukazi umthelela wokubunjwa kwefomula ecwebezelayo yobuso kumaphutha ephinifa, lidingida ubudlelwane phakathi kwesilinganiso se-flux kanye nenani eliphelele kufomula enebanga elibanzi lokudubula kanye nobubanzi obubanzi bokusebenza, kanye nobudlelwano phakathi kwesilinganiso sezinto eziphakeme zokushisa kanye nevolumu ephelele, futhi ixoxa ngesixazululo sokulawula okusheshayo nangempumelelo kanye nokunciphisa amaphutha e-glaze pinhole.
Ukuhlolwa kwaqedwa ebhizinisini le-ceramic elaziwayo e-Qingyuan, ubude behhavini babungu-325m, umjikelezo wokudubula wawuyi-48min, izinga lokushisa lendandatho lalingu-1166-1168 ° C, i-glaze yobuso isetshenziswe ngokuklabha i-glaze, kanye ne-glaze. kwasetshenziswa indlela yokucwebezela ukuze kucwebezeliswe ngokugcwele, futhi inani lamaphutha emigodini endaweni engu-400mm ×800mm labalwa.Ukwakheka komzimba oluhlaza, ukucwebezela okugcwele nezinto ezingavuthiwe ezisetshenziselwa ukucwebezela okusetshenziswe ekuhlolweni kukhonjisiwe kuThebula 1.
2.1 Ukuhlolwa komthelela wesilinganiso se-flux kanye nesilinganiso senhlabathi eshisiwe/i-aluminium eshisiwe emigodini yamaphinifa
Okwangempela: i-albite 12, i-potassium feldspar 31, i-quartz 20, i-gas knife earth 10, i-aluminium eshile engu-22, i-frit ephansi yokushisa engu-3, i-nepheline 7, i-zirconium silicate 9.
Ukuhlolwa kwezinga le-3-factor ezimbili kuklanywe ngesisekelo sesikwele sokuqala, okuhlanganisa i-factor A - flux ratio, factor B - inhlabathi eshisiwe/i-aluminium eshisiwe isilinganiso (i-quartz, umhlaba wommese wegesi, inani le-frit lokushisa eliphansi lihlala lingashintshiwe).
A: i-potassium feldspar, i-albite ye-nepheline ngesilinganiso esingu-3:1:3, ileveli 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: I-aluminium eshisiwe yenhlabathi eshisiwe ngokwesilinganiso esingu-3:5, B1 (i-aluminium eshisiwe/inhlabathi eshile = 19/6), B2 (i-aluminium eshile/inhlabathi eshile = 16/11), B3 (i-aluminium eshile/inhlabathi eshile = 13/16)
Kunezici eziningi ezidala ukungasebenzi kahle kwemigodi, futhi kubaluleke kakhulu ukulungisa iphutha nokuthuthukisa ukwakheka kwefomula kanye nobubanzi bokudubula obucwebezelayo obungenaphinikhodi.Ngokukhula kwengxenye ye-nepheline ku-glaze formula, ingxenye ye-potassium feldspar ne-albite yehla, futhi amaphinikhodi abonisa ukuthambekela okunciphayo.Ngokukhula kwengxenye yenhlabathi eshisiwe, ingxenye ye-alumina e-calcined iyancipha, futhi amaphinikhodi abonisa umkhuba okhulayo, futhi ngokuphambene nalokho.Lapho inhlabathi eningi kanye ne-quartz equkethwe kwifomula, lapho indawo engenazimbobo incipha, iba ncane indawoukusetshenziswa kwefomula,kulapho okuqukethwe kwe-nepheline ne-alumina e-calcined, kulapho ububanzi befomula engenazo izimbobo, futhi kuba banzi ububanzi bokusetshenziswa kwefomula.
(1) Amaphinikhodi ahlukaniswe abe izinhlobo ezimbili: amaphinifa anezinga lokushisa eliphansi kanye nezikhonkwane ezinezinga eliphezulu lokushisa, futhi izici ezivamile zamaphinikhodi asezingeni eliphansi yilezi: inani lamaphinifa likhulu, ubukhulu buncane, buhambisana nenani elikhulu lama-pinhole. amaphutha, kanye nokucwebezela okukodwa okuphansi empeleni akumunyi noma kuncane kakhulu;Izici ezijwayelekile zamaphinikhodi asezingeni eliphezulu yilezi: inani lamaphinikhodi lincane, ubukhulu bukhulu, ukushisa kwe-prickly kuncane, okuhambisana nokukhubazeka kwe-crater, futhi i-glaze ephansi eyodwa inzima kakhulu ekumunceni uyinki.
(2) Ngokulimala kwe-pinhole ekukhiqizeni, kuyadingeka okokuqala ukunquma ukuthi ingabe iphinifa elinezinga lokushisa eliphansi noma imbobo enezinga eliphezulu lokushisa, ngokuya ngesimo sangempela, i-alumina ekhandiwe ikhethwa ukuxazulula iphinifa elinezinga lokushisa eliphansi, kanye ne-nepheline. kuncanyelwa ukwelapha iphinifa elinezinga lokushisa eliphezulu.
(3) I-quartz njengento eshisa kakhulu emazingeni okushisa aphezulu kufomula ecwebezelayo engezansi yokuthuthukisa izinga lokushisa elicwebezelayo elingaphezulu kanye ne-viscosity yokushisa ephezulu ayibonakali kangako kune-alumina eqoshiwe, futhi okuqukethwe kwe-quartz okwengeziwe, indawo encane engenamaphinikhodi, iyancipha ububanzi beukusetshenziswa kwefomula.
Okuqukethwe okuvela ku-FOSHAN CERAMIC MEGACINE
