Impilo yesevisi ye-graphite silicon carbide crucible

I-graphite silicon carbide crucibleszingamathuluzi abalulekile ezimbonini zokuphonsa nokuncibilika kwensimbi futhi zaziwa ngokuhlala kwazo isikhathi eside kanye nokumelana nezinga lokushisa eliphezulu. Kodwa-ke, impilo yesevisi yalezi ziphambano ithintwa yizici ezihlukahlukene ezibalulekile ekwandiseni ubude bayo besikhathi eside nokusebenza kahle.

Izinga lokushisa elisebenzayo lidlala indima ebalulekile ekunqumeni impilo yesevisi ye-graphite silicon carbide crucibles. Ukuphakama kwezinga lokushisa lokusebenza, kuba mfushane impilo yesevisi ye-crucible. Lokhu kungenxa yokucindezeleka okushisayo okwenyukayo okwenzeka ku-crucible emazingeni okushisa aphezulu, okwenza kube lula ukuqhekeka nokuguga. Ngakho-ke, amazinga okushisa okusebenza kufanele aqashwe ngokucophelela futhi alawulwe ukuze kuqinisekiswe impilo yesevisi ye-crucible eyengeziwe.

Inombolo yokusetshenziswa izophinde ithinte impilo yesevisi ye-graphite silicon carbide crucible. Ngemuva kokusetshenziswa ngakunye, ama-crucibles abhekana nokuguga nokugqwala, okwenza impilo yabo yesevisi yehle kancane kancane. Ngakho-ke, lapho kusetshenziswa i-crucible, impilo yayo yesevisi izoba mfushane. Ukuhlolwa njalo nokunakekelwa kubalulekile ekuhlonzeni izimpawu zokuguga nokugqwala kanye nokunquma isikhathi esifanele sokushintshwa.

Ngaphezu kwalokho, indawo yamakhemikhali lapho kusetshenziswa khona i-crucible nayo ithinta kakhulu impilo yayo yesevisi. I-graphite silicon carbide crucibles ibonisa amazinga ahlukene okumelana nokugqwala ezindaweni ezihlukene zamakhemikhali. Uma isetshenziswa ezindaweni ezibola kakhulu, impilo yesevisi ye-crucible ifinyezwa nakanjani. Ngakho-ke, kubalulekile ukuhlola indawo yamakhemikhali bese ukhetha i-crucible enokumelana nokugqwala okufanele ukuze kuqinisekiswe ukusebenza kahle nokuphila isikhathi eside.

Ukusetshenziswa okufanele kwe-graphite silicon carbide crucibles kubalulekile ekwandiseni impilo yabo yesevisi. Ukusetshenziswa okungafanele, njengokufaka i-crucible ekushintsheni okungazelelwe kwezinga lokushisa noma ukuwisa izinto ezibandayo kuyo, kungathinta kakhulu ukuqina kwayo. Ukulandela imihlahlandlela yokusetshenziswa enconyiwe kanye nezinqubo zokuphatha kubalulekile ekwandiseni impilo ye-crucible yakho kanye nokuvimbela ukuguga nokulimala ngaphambi kwesikhathi.

Ukunamathela kanye nokuba khona kwezingqimba ze-oxide ku-crucible nakho kungathinta ukusebenza kwayo nokuphila kwesevisi. Ukuhlanza njalo nokunakekela ukususa noma yiziphi izendlalelo ezinamathelayo noma ezine-oxidized kubalulekile ukuze uqinisekise impilo ende nokusebenza kahle kwe-crucible yakho.

Lapho uhlola impilo yesevisi ye-graphite silicon carbide crucibles, kubalulekile ukucabangela izimo ezithile zokusebenza nendawo yokusetshenziswa. Impilo yesevisi ingase ihluke ngokusekelwe ezicini ezifana nezinga lokushisa, ukuchayeka kumakhemikhali, nezindlela zokusetshenziswa. Ukuhlola nokuhlola kufanele kwenziwe njalo ukuze kunqunywe impilo yesevisi yangempela ye-crucible kanye nokuhlonza noma yiziphi izimpawu zokuguga noma ukuwohloka.

Kafushane, ukukhulisa impilo yesevisi ye-graphite silicon carbide crucibles kudinga ukucatshangelwa ngokucophelela kwezici ezihlukahlukene, okuhlanganisa izinga lokushisa lokusebenza, imvamisa yokusetshenziswa, indawo yamakhemikhali, ukusetshenziswa okufanele kanye nokuhlola ngezikhathi ezithile. Ngokuthobela izinqubo zokusetshenziswa ezinconyiwe kanye nokwenza ukunakekelwa okujwayelekile, ungakwazi ukunweba impilo yalezi ziphambano, uqinisekise ukusebenza kahle nokuthembekile ekusebenzeni kokusakazwa kwensimbi nokuncibilika.

 

 

Impilo yesevisi ye-graphite silicon carbide crucibles ibilokhu iyisihloko esikhathazayo embonini yezinto zokwakha njengoba lezi zinsimbi zidlala indima ebalulekile ekusetshenzisweni okuhlukahlukene kokushisa okuphezulu njengokuphonswa kwensimbi, ukukhiqizwa kwengilazi kanye nocwaningo lwaselabhorethri. Ucwaningo lwakamuva olwenziwe ngososayensi bezinto ezibonakalayo luveza izici ezithonya impilo yesevisi yalezi zinsimbi futhi luhlinzeka ngemininingwane ebalulekile ekuthuthukiseni ukuqina nokusebenza kwayo.

I-graphite silicon carbide crucibles yaziwa ngokusebenza kwayo okushisayo okuhle kakhulu, ukumelana nokushaqeka okuphezulu kokushisa kanye nokungangeni kwamakhemikhali okuqinile, okuyenza ibe ilungele ukumelana namazinga okushisa adlulele kanye nezindawo zamakhemikhali ezinokhahlo. Kodwa-ke, ngaphandle kwalezi zici ezivumayo, impilo yesevisi yalezi ziphambano ingase ithintwa izici ezihlukahlukene, okuhlanganisa izimo zokusebenza, ikhwalithi yezinto ezibonakalayo, nezinqubo zokukhiqiza.

Ucwaningo luye lwabonisa ukuthi impilo yesevisi ye-graphite silicon carbide crucibles ithintwa kakhulu izinga lokushisa lokusebenza kanye nemijikelezo yokushisa. Ukuchayeka isikhathi eside kumazinga okushisa aphezulu kanye nokushintsha kwezinga lokushisa okusheshayo kungabangela ingcindezi yokushisa nokonakala komshini, ekugcineni kufinyeze impilo yesevisi ye-crucible. Ukwengeza, ikhwalithi yempahla e-crucible kanye nobuchwepheshe bokukhiqiza obusetshenzisiwe bungathinta kakhulu ukusebenza kwayo nokuphila isikhathi eside.

Ukuze kubhekwane nalezi zinselele, abacwaningi baye bahlongoza amasu amaningana okuthuthukisa impilo yesevisi ye-graphite silicon carbide crucibles. Enye indlela ihilela ukwenza kahle ukwakheka kanye ne-microstructure ye-crucible material ukuthuthukisa amandla ayo okusebenza kanye nokumelana nokushaqeka kokushisa. Ukwengeza, inqubekelaphambili kubuchwepheshe bokukhiqiza obufana nokubumba ukunemba kanye nezinqubo ze-sintering kungasiza ukukhiqiza ama-crucibles aminyene futhi angenazimbotshana, ngaleyo ndlela athuthukise ukuqina kwawo kanye nokumelana namakhemikhali.

Ukwengeza, lolu cwaningo luqokomisa ukubaluleka kokuphatha nokugcinwa ngendlela efanele ukuze kunwetshwe impilo yesevisi ye-graphite silicon carbide crucibles. Ukusebenzisa imijikelezo elawulwayo yokushisisa nokupholisa, ukugwema ukushintsha okungazelelwe kwezinga lokushisa, nokuhlola njalo izimpawu zokuguga nokulimala kuyizinyathelo ezibalulekile zokwandisa impilo yesevisi ye-crucible yakho.

Imiphumela yalolu cwaningo inezingqinamba eziphawulekayo ezimbonini ezithembele ezinkambisweni zokushisa okuphezulu, njengoba impilo yesevisi eyengeziwe ye-graphite silicon carbide crucibles ingaholela ekongeni kwezindleko, ukwanda kokukhiqiza kanye nokunciphisa isikhathi sokuphumula. Ngokuqonda izici ezithinta ukusebenza kwe-crucible nokusebenzisa amasu anconyiwe, abakhiqizi nabacwaningi bangaqinisekisa ukusebenza okuthembekile nokuhlala isikhathi eside kwalezi zingxenye ezibalulekile ekusetshenzisweni okuhlukahlukene.
