Njengengxenye ebalulekile yensimu yokuvikela ukuguguleka kwezimboni, ukumelana nokushisa okuphezulu kwezitsha zobumba ezingagugi bekulokhu kungenye yezinto ezigxilwe kakhulu kuwo wonke umuntu. Ikakhulukazi kwezinye izimo zokusebenza ezinezinguquko ezinkulu zokushisa noma izinga lokushisa eliphezulu, ukukhetha uhlobo olufanele lwezitsha zobumba ezingagugi kanye nendlela efanele yokufaka kubaluleke kakhulu ekukhiqizweni okuphephile nokonga amandla kanye nokusebenza kahle okuphezulu. Ngakho-ke yiziphi izici eziyinhloko ezithinta ukumelana nokushisa okuphezulu kwezitsha zobumba ezingagugi?
1. Ukuhlanzeka kwezinto zobumba olumelana nokuguguleka: Izibumba ezimelana nokuguguleka esivame ukukhuluma ngazo ikakhulukazi zibhekisela kuzibumba ezimelana nokuguguleka ze-alumina, kanti ukuhlanzeka kwe-alumina kunomthelela oqondile ekumelaneni nokushisa okuphezulu kwezibumba ezimelana nokuguguleka. Izibumba ezimelana nokuguguleka ze-alumina zishiswa ekushiseni okuphezulu okungu-1700°C futhi zinokumelana okuhle kakhulu nokushisa okuphezulu. Kodwa-ke, ekusetshenzisweni okungokoqobo, uma ukuhlanzeka kwe-alumina kungaphakeme, izibumba zizoqukatha ezinye izakhi. Lezi zinto zizobonisa izakhiwo ezahlukene zokukhula nokuqina kokushisa emazingeni okushisa aphezulu noma ukupholisa nokushisa okungazelelwe ngenxa yezakhiwo ezahlukene. Lesi simo asibonakali lapho izinga lokushisa lishintsha kancane noma ububanzi bokushintsha buncane, kodwa lapho izinga lokushisa lishintsha kakhulu noma lihlangana nokushisa okuphezulu okungu-800, 900 noma ngisho no-1,000 degrees, lolu shintsho luzoba nomthelela omkhulu, futhi izibumba ezihlanzekile kakhulu kudingeka zikhethwe.
2. Indlela yokufaka: Indlela yokufaka izinto zobumba ezingagugi nayo inomthelela oqondile ekumelaneni nokushisa okuphezulu kwezinto zobumba. Isibonelo, lapho kusetshenziswa into yokunamathisela izinto zobumba evamile ukunamathisela izinto zobumba, izinga lokushisa eliphezulu elingamelana nalo lingaba ngu-150°C. Into yokunamathisela enokushisa okuphezulu ingakhuphula leli zinga lokushisa libe ngu-200°C, kodwa uma izinga lokushisa lokumelana nento yokunamathisela selidluliwe, i-viscosity yento yokunamathisela izothinteka, okungabangela kalula ukuthi into yobumba iwe. Uma kuqhathaniswa nendlela yokunamathisela, izinto zobumba ezifakwe ngendlela yokushisela i-stud kanye ne-dovetail slot zingamelana nokushisa okuphezulu okungu-750°C. Ipayipi le-ceramic elingagugi elenziwe ngokuhlanganisiwe linganciphisa kakhulu umkhawulo wendlela yokufaka ekumelaneni nokushisa kwezinto zobumba.
3. Izinto ezihlanganiswe nge-ceramics: I-ceramics ivame ukusetshenziswa ngokuhlanganiswa nezinye izinto, njengezinsimbi, irabha, njll. Kulokhu, lapho sahlulela ukumelana nokushisa okuphezulu kwe-ceramics engagugi, kumelwe sicabangele ukumelana nokushisa kwezinto ezihlanganisiwe. Isibonelo, izinto ezihlanganisiwe ze-ceramic-raber azifanele ukusetshenziswa ezimweni zokushisa okuphezulu.
Ngamafuphi, kunezici ezintathu eziyinhloko ezithinta ukumelana nokushisa okuphezulu kwezitsha zobumba ezingagugi, ngakho-ke lezi zinto zidinga ukucatshangelwa ngokuphelele lapho kukhethwa izitsha zobumba ezingagugi.
