Izingxenye ze-granite ezinembile:
Ukuminyana kusuka ku-2.79 kuye ku-3.07g/cm³ (inani eliqondile lingahluka kuye ngohlobo lwegwadle nendawo yomsuka). Lobu bubanzi bokuminyana benza izingxenye zegwadle zibe nokuzinza okuthile ngesisindo futhi akulula ukunyakaza noma ukonakala ngenxa yamandla angaphandle.
Izingxenye ze-ceramic eziqondile:
Ukuminyana kuyahlukahluka kuye ngokuthi ukwakheka okukhethekile kwe-ceramic kanye nenqubo yokukhiqiza. Ngokuvamile, ukuminyana kwezitsha zobumba ezinemba okuphezulu kungase kube phezulu, njengokuminyana kwezinye izingxenye ze-ceramic eziqinile ezingagugi zingafinyelela ku-3.6g/cm³, noma ngisho nangaphezulu. Kodwa-ke, ezinye izinto ze-ceramic zenzelwe ukuthi zibe nokuminyana okuphansi kwezinhlelo zokusebenza ezithile, njengokungasindi.
Umthelela ezinhlelweni zokusebenza
1. Ukuthwala umthwalo nokuzinza:
Ukuminyana okuphezulu ngokuvamile kusho umthamo ongcono wokuthwala umthwalo nokuzinza. Ngakho-ke, esidingweni sokuthwala isisindo esikhulu noma ukugcina izikhathi ezinembayo eziphezulu (njengesisekelo samathuluzi omshini, inkundla yokulinganisa, njll.), izingxenye zegwadle zokunemba okuphezulu kakhulu zingase zifaneleke kakhulu.
Nakuba ukuminyana kwezingxenye ze-ceramic ezinembayo kungase kube phezulu, ukusetshenziswa kwayo okuqondile nakho kudinga ukucabangela ezinye izici (ezifana nokuqina, ukumelana nokugqoka, njll.) kanye nezidingo zomklamo zizonke.
2. Izidingo ezingasindi:
Kwezinye izinhlelo zokusebenza, njenge-aerospace, kunezidingo eziphezulu zezinto ezingasindi. Ngalesi sikhathi, nakuba izitsha zobumba ezinembayo zinhle kakhulu kwezinye izici, ukuminyana kwazo okuphezulu kungase kukhawulele ukusetshenziswa kwazo kulezi zindawo. Ngokuphambene nalokho, ngokuthuthukisa ukuklama nokukhethwa kwezinto ezibonakalayo, isisindo sezingxenye ze-ceramic ngokunemba singancishiswa ngezinga elithile ukuze kuhlangatshezwane nezidingo ezithile.
3. Ukucubungula kanye nezindleko:
Izinto ezinokuminyana okuphezulu zingadinga amandla amakhulu okusika kanye nezikhathi zokucubungula ezinde phakathi nokucubungula, ngaleyo ndlela kwandise izindleko zokucubungula. Ngakho-ke, ekukhethweni kwezinto zokwakha, ngaphezu kokucabangela ukusebenza kwayo, kuyadingeka futhi ukucabangela ubunzima bokucubungula kanye nezici zezindleko.
4. Inkambu yohlelo lokusebenza:
Ngenxa yokuqina kwayo okuhle namandla okuthwala umthwalo, izingxenye zegwadle ezinembayo zisetshenziswa kabanzi ekulinganiseni ukunemba, amathuluzi okubona, ukuhlola kwe-geological kanye neminye imikhakha.
Izingxenye ze-ceramic eziqondile zinezinzuzo eziyingqayizivele ku-aerospace, amandla, amakhemikhali kanye nezinye izinkambu zobuchwepheshe obuphezulu ngenxa yokumelana kwazo okuphezulu kwezinga lokushisa, ukumelana nokugqoka, amandla aphezulu nezinye izici.
Kafushane, kunomehluko wokuminyana phakathi kwezingxenye zegwadle ezinembayo kanye nezingxenye ze-ceramic ezinembayo, futhi lo mehluko uthinta izinkambu zokusetshenziswa kwazo nezindlela ezithile zokusebenzisa ngokwezinga elithile. Ekusetshenzisweni okungokoqobo, izinto ezifanele kufanele zikhethwe ngokuvumelana nezidingo ezithile kanye nemibandela ukuze kuzuzwe ukusebenza okungcono kakhulu kanye nezinzuzo zezomnotho.
