Njengengxenye ebalulekile yensimu yokuvikela ukugqokwa kwezimboni, ukumelana nokushisa okuphezulu kweizitsha zobumba ze-aluminabekulokhu kungenye yezinto ezigxilwe kakhulu yiwo 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. Ubumsulwa bezinto ze-alumina ceramics: Izinto ze-ceramics ezingagugi esivame ukukhuluma ngazo ikakhulukazi zibhekisela ezintweni ze-alumina ezingagugi, kanti ubumsulwa be-alumina bunomthelela oqondile ekumelaneni nokushisa okuphezulu kwezinto ze-ceramics ezingagugi. Izinto ze-ceramics ezingagugi ze-alumina zishiswa ekushiseni okuphezulu okungu-1700°C futhi zinokumelana nokushisa okuphezulu okuhle kakhulu. Kodwa-ke, ekusetshenzisweni kwangempela, uma ubumsulwa be-alumina bungekho phezulu, izinto ze-ceramics 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 kuyadingeka ukukhetha izinto ze-ceramics ezihlanzekile kakhulu, njengezinto ze-alumina ze-alumina ze-Jingcheng's K99.
2. Indlela yokufaka: Indlela yokufaka izinto zobumba ezimelana nokuguguleka nayo inomthelela oqondile ekumelaneni nokushisa okuphezulu kwezinto zobumba. Isibonelo, lapho kusetshenziswa into yobumba evamile ukunamathisela izinto zobumba, izinga lokushisa eliphezulu engalimela lingaba ngu-150°C. Into yobumba ekhethekile kaJingcheng ingakhuphula leli zinga lokushisa libe ngu-350°C, kodwa uma izinga lokushisa lento yobumba selidlulile, i-viscosity yento yobumba izokwehla kakhulu, okungabangela ukuthi i-ceramic iwe kalula. Uma kuqhathaniswa nendlela yokunamathisela, indlela yokushisela i-stud kanye nezinto zobumba ezifakwe yi-dovetail slot zingamelana nokushisa okuphezulu okungu-750°C. Ipayipi le-ceramic elingaguguleki elihlanganiswe ndawonye elisanda kuthuthukiswa futhi lakhiqizwa yiJingcheng linganciphisa kakhulu umkhawulo wendlela yokufaka ekumelaneni nokushisa kwezinto zobumba.
3. Izinto ezihlanganiswe ne-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 zerabha ze-ceramic azifanele ukusetshenziswa ezimweni zokushisa okuphezulu.
Ngamafuphi, kunezici ezintathu eziyinhloko ezithinta ukumelana nokushisa okuphezulu kwe-izitsha zobumba ezingagugi, okungukuthi ubumsulwa bezinto zobumba ngokwazo, indlela yokufaka izinto zobumba, kanye nezinto ezihlanganiswe nezinto zobumba. Lezi zici kudingeka zicatshangelwe ngokuphelele lapho kukhethwa izinto zobumba ezingagugi.
