Izinsimbi ze-clay graphite, ezaziwa nangokuthi izinqwaba ze-graphite noma izilebhe zethusi ezincibilikisiwe, zingamathuluzi abalulekile emkhakheni wokuncibilikisa insimbi.Lezi zinhlayiya zisetshenziselwa ngokuyinhloko ukuncibilikisa izinsimbi ezingenayo insimbi njengethusi, ithusi, igolide, isiliva, i-zinc, nomthofu, kanye nama-alloys azo.Inqubo yokukhiqiza ye-clay graphite crucibles ihilela ukusetshenziswa kwe-graphite yemvelo ye-flake njengento eluhlaza eyinhloko, kanye nobumba nezinye izinto eziphikisayo.
Ingxenye yobumba ye-crucible kumele ibe msulwa, ibe ne-plasticity eqinile, izakhiwo ezinzile ngokomzimba namakhemikhali, futhi ibe ne-refractoriness ephezulu kanye nemiphumela emihle yokushisa.Ngochungechunge lokuxuba, ukubumba, kanye nezinyathelo zokudubula, i-crucible ephezulu yokusebenza ikhiqizwa.Enye yezinzuzo ezibalulekile ze-clay graphite crucibles ukumelana nomlilo okungavamile kanye nokuzinza kokushisa.Ukuba khona kwe-graphite kuvumela lezi zinsimbi ukuba zimelane namazinga okushisa aphezulu, okubalulekile ekwenzeni izinqubo zokuncibilikisa insimbi.
Ngaphezu kwalokho, ingxenye yobumba ye-crucible inikeza ukufakwa okuhle kakhulu kokushisa okushisayo, okuholela enkambisweni efanayo yokuncibilikisa insimbi.Lokhu kuncibilika kusiza ukugcina izinga lokushisa eliphezulu elidingekayo ukuze kuncibilikiswe kahle.Ukwengeza, ama-clay graphite crucibles abonisa ukumelana nokushaqeka okumangalisayo.Lokhu kusho ukuthi ngisho nalapho i-crucible ishintsha ngokuzumayo futhi izinga lokushisa elidlulele phakathi nenqubo yokuncibilikisa, ingakwazi ukumelana nokushaqeka okushisayo futhi iqinisekise ukuqhubeka kahle kokusebenza kokuncibilikisa insimbi.
Mayelana nokuzinza kwamakhemikhali, izinsimbi ze-clay graphite crucibles zibonisa ukumelana okuhle nokusabela kwamakhemikhali ngezinsimbi ezincibilikisiwe.Lokhu kubalulekile ekugcineni izinga nokuhlanzeka kwensimbi ekhiqizwayo.Ukuzinza kwe-crucible kuvimbela noma yikuphi ukusebenzisana kwamakhemikhali okungafuneki okungafaka engozini ubuqotho bensimbi.
Sekukonke, ama-clay graphite crucibles angamathuluzi akhethekile okuncibilikisa insimbi.Ukumelana kwabo nomlilo okuhle kakhulu, ukuzinza kokushisa, ukumelana nokushaqeka kokushisa, nokuzinza kwamakhemikhali kubenza basetshenziswe kabanzi embonini.Noma yimuphi uchwepheshe ohileleke ekuncibilikiseni insimbi uyakuqonda ukubaluleka kwamathuluzi asebenza kahle kakhulu, futhi izinsimbi ze-graphite zobumba ziwufanela kahle umthethosivivinywa.Ngokuhlala kwabo isikhathi eside nokusebenza okuyingqayizivele, lezi zinsimbi zisiza ukuqinisekisa ukuncibilika okuphumelelayo nokusebenza kahle kwezinsimbi ezingenayo insimbi kanye nama-alloys azo.
Ekuphetheni, ama-clay graphite crucibles ayingxenye ebalulekile emkhakheni wokuncibilikisa insimbi.Inqubo yabo yokukhiqiza ihilela inhlanganisela ngokucophelela ye-flake yemvelo ye-graphite, ubumba, nezinye izinto eziphikisayo.Lawa ma-crucibles anikeza ukumelana nomlilo okuhle kakhulu, ukuzinza kokushisa, ukumelana nokushaqeka okushisayo, nokuzinza kwamakhemikhali.Ikhono lazo lokumelana namazinga okushisa aphakeme, linikeze ukushiswa kokushisa, ukumelana nokushaqeka kokushisa, nokugwema ukusabela kwamakhemikhali kubenza babaluleke kakhulu embonini yokuncibilikisa.Ngakho-ke, kungakhathaliseki ukuthi uncibilikisa ithusi, ithusi, igolide, isiliva, i-zinc, i-lead, noma ama-alloys awo, ama-clay graphite crucibles ayisinqumo esinokwethenjelwa senqubo yokuncibilikisa ephumelelayo nekhwalithi ephezulu.
