Izici eziphambili zenqubo ezithinta ukuncibilika kwengilazi

Izici eziphambili zenqubo ezithinta ukuncibilika kwengilazi zinwebeka ngale kokuncibilika kwesiteji uqobo, ngoba zithonywa yizimo zangaphambi kokuncibilika njengekhwalithi ebonakalayo esetshenziswayo njengekhwalithi eluhlaza ebonakalayo njengekhwalithi eluhlaza eluhlaza okwesikhashana, ukwelashwa okuvuselelayo, izinsiza zokulawula, kanye nokukhethwa kwengcindezi yokuhlawulela. Ngezansi ukuhlaziya okuningiliziwe kwalezi zinto:

Ⅰ. Ukulungiswa okubonakalayo okubonakalayo nokulawulwa kwekhwalithi

1. Ukwakheka kwamakhemikhali kwe-batch

I-Sio₂ ne-Refractory Compounds: Okuqukethwe yiSio₂, Al₂o₃, iZro₂, nezinye izinhlanganisela zokuvusezwa zithinta ngqo izinga lokuncibilika. Okuqukethwe okuphezulu kukhulisa izinga lokushisa elidingekayo nokusetshenziswa kwamandla.

I-Alkali Metal oxides (isib. Na₂o, Li₂o): Yehlisa izinga lokuncibilika. I-Li₂o, ngenxa ye-Ionic Radius yayo encane ne-electronegativity ephezulu, iyasebenza kakhulu futhi ingathuthukisa izakhiwo ezibonakalayo zengilazi.

2. Ukwelashwa kwangaphambili

Ukulawula Umswakama:

Umswakama ofanele (3% ~ 5%): uthuthukisa ukumanzisa nokuphendula, kunciphisa uthuli nokwehlukaniswa;

Umswakama owedlulele: Kudala amaphutha anesisindo kanye nesikhathi sokuhlawulisa.

Ukusatshalaliswa kosayizi wezinhlayiyana:

Izinhlayiya ezinobunzima obukhulu: zinciphisa indawo yokuxhumana yokuxhumana, isikhathi eside sokuncibilika;

Izinhlayiya ezinhle kakhulu: ziholela ekulweni ne-agglomeraling kanye ne-elektrostatic adsorption, ukuvimbela ukuncibilika komfaniswano.

3. Ukuphathwa kweCullet

I-CUllet kumele ihlanzeke, ingenakungcola, bese iqondanisa usayizi wezinhlayiyana zezinto zokusetshenziswa ezintsha zokugwema ukwethula ama-bubble noma izinsalela ezingenamsebenzi.

Ⅱ. Idizayini Yesithandokanye nezakhiwo zikaphethiloli

1. Ukukhethwa kwezinto ezibonakalayo

Ukumelana nokuguguleka okushisa kakhulu: Izitini eziphakeme ze-zirconium kanye nezitini ze-zirfoofuse

Ukuqina okushisayo: Melana nokuguquguquka kokushisa futhi uvikele ukusakazeka kokuzenzakalelayo ngenxa yokushaqeka kwe-thermal.

2. Amafutha nokusebenza kahle

Inani lamakhalori kaphethiloli kanye nomoya wokuvutha (oxidizing / ukunciphisa) kufanele kuhambisane nokwakheka kwengilazi. Ngokwesibonelo:

Igesi yemvelo / i-oyela esindayo: kudinga ukulawulwa kokulawulwa komoya okunembile komoya ukugwema izinsalela ze-sulfide;

Ukuncibilika kukagesi: Kulungele ukuncibilika okunembile okuphezulu (isib.ingilazi ye-optical) kepha uqeda amandla amaningi.

Ⅲ. Inqubo yokuncibilika inqubo yepharamitha

1. Ukulawulwa kokushisa

Ukushisa okuncibilikayo (1450 ~ 1500 ℃): Ukunyuka okungu-1 Ibhalansi phakathi kokusebenza kahle kanye nokuphila kwemishini kuyadingeka.

Ukusatshalaliswa kwamazinga okushisa

2. I-Atmosphere nengcindezi

Umoya oxerizing:

Ukunciphisa umkhathi: ukucindezela uFe³ + Umbala (wengilazi engenamibala) kodwa kudinga ukugwema ukubekwa kwekhabhoni;

Ukuqina kwengcindezi yesithando: Ingcindezi emnandi (+ 2 ~ 5 pa) ivimbela ukubanda komoya futhi kuqinisekise ukususwa kwe-bubble.

Ama-ejenti we-3.Fining

Ama-fluorides (isib. Caf₂): nciphisa ukuncibilika nokushesha ukususwa kwe-bubble;

Ama-nitrate (isib., Nano₃): khipha umoya-mpilo ukuze ukhuthaze inhlawulo ye-oxidative;

I-Composite Fluxes **: Isib.

Ⅳ. Ukuqapha okunamandla kwenqubo yokuncibilika

1. Ncibilikisa ukuhlakanipha noshukela

Ukuqapha kwesikhathi sangempela usebenzisa ama-videscoeter ajikelezayo ukuguqula izinga lokushisa noma ama-flux ngezimo ezifanele zokwakha.

2. Ukusebenza kahle kwe-Bubble Ukususa

Ukuqashelwa kokusatshalaliswa kwe-bubble usebenzisa amasu we-X-ray noma ama-imeyili ukuze uthuthukise umthamo we-ejenti wokuhlawulisa kanye nengcindezi yemfashini.

Ⅴ. Izinkinga ezijwayelekile namasu wokuthuthuka

Ukugcina

Ukuncibilika kwengilazi kungumphumela wokusebenzisana phakathi kwezinto ezingavuthiwe, imishini, kanye namapharamitha enqubo. Kudinga ukuphathwa ngokucophelela kokuklanywa kokwakheka kwamakhemikhali, ukusebenziseka kosayizi wezinhlayiyana, ukuthuthukiswa kwezinto ezibonakalayo, kanye nokulawulwa kwephasela lenqubo enamandla. Ngokulungisa i-fluxes ngokwesayensi, okuqinisa indawo yokuncibilika (lokushisa / ingcindezi / umkhathi), kanye nokusebenzisa amasu wokuhlawulisa okusebenzayo, ukusebenza kahle kwengilazi kungathuthukiswa kakhulu, kanti izindleko zengilazi zincishiswa kakhulu.
