Ekukhetheni izingxenye zesakhiwo, amandla okucindezela kwezinto zokwakha ayinto ebalulekile. Njengoba izinto ezimbili ezivamile zesakhiwo, amalungu e-granite aqondile kanye namalungu e-ceramic aqondile abonisa izici ezahlukene ngamandla okucindezela, ezinethonya elikhulu ekukhetheni nasekusetshenzisweni kwezingxenye zesakhiwo.
Ukuqhathaniswa kwamandla okucindezela
Izingxenye ze-granite eziqondile:
I-granite enembile njengetshe lemvelo, amandla ayo okucindezela aphezulu impela. Ngokuvamile, amandla okucindezela e-granite angafinyelela amakhulu ama-megapascals (MPa) noma ngaphezulu, okwenza isebenze kahle ngaphansi kwemithwalo yengcindezi. Amandla aphezulu okucindezela e-granite abangelwa kakhulu yisakhiwo sayo esiqinile sekristalu kanye nobunzima obuphezulu, okwenza i-granite ibe yinto ebalulekile kubunjiniyela bezakhiwo ezisindayo njengezakhiwo, amabhuloho kanye nemigwaqo.
Izingxenye ze-ceramic eziqondile:
Ngokuphambene nalokho, izingxenye ze-ceramic ezinembile nazo zisebenza kahle ngamandla okucindezela, kodwa inani elithile lizothinteka yizici ezifana nokwakheka kwezinto kanye nenqubo yokulungiselela. Ngokuvamile, amandla okucindezela e-ceramic ezinembile angafinyelela ezinkulungwaneni zama-megapascals (MPa) noma ngaphezulu. La mandla aphezulu abangelwa kakhulu yisakhiwo sekristalu esiqinile ngaphakathi kwezinto ze-ceramic kanye nesibopho esinamandla se-ionic, isibopho se-covalent kanye nezinye izibopho zamakhemikhali. Kodwa-ke, kufanele kuqashelwe ukuthi yize amandla okucindezela e-ceramic ezinembile ephezulu, amandla ayo okudonsa kanye namandla okusika aphansi kakhulu, futhi ubuthakathaka bayo bukhulu, okunciphisa ukusetshenziswa kwayo kwezinye izinkambu ngezinga elithile.
Ithonya ekukhetheni izingxenye zesakhiwo
Ukucatshangelwa kwesimo sesicelo:
Uma ukhetha izingxenye zesakhiwo, udinga ukwazi isimo sesicelo kanye nezidingo ezithile. Ngezikhathi ezidinga ukumelana nemithwalo emikhulu yokucindezela, njengeBridges, imigudu, izakhiwo eziphakeme kanye neminye imisebenzi yesakhiwo esindayo, izingxenye zegranite eziqondile ziba yisinqumo sokuqala ngenxa yamandla azo aphezulu okucindezela kanye nokuqina okuhle. Kwezinye izikhathi ezidinga ukunemba okuphezulu kanye nokuzinza, njengezinsimbi zokulinganisa ngokunembile, imishini ye-semiconductor kanye nezinye izinkambu, izingxenye ze-ceramic eziqondile ziyathandwa ngenxa yokushisa kwazo okuphezulu kanye ne-coefficient yokukhulisa ukushisa ephansi.
Ibhalansi yezindleko nezinzuzo:
Ngaphezu kokucabangela amandla okucindezela kwezinto, kuyadingeka futhi ukucabangela ngokuphelele izici ezifana nezindleko, ubunzima bokucubungula, kanye nezindleko zokulungisa. Nakuba ingxenye ye-granite enembile inamandla aphezulu okucindezela, kunzima ukuyicubungula futhi izindleko ziphakeme kakhulu. Nakuba ingxenye ye-ceramic enembile inezakhiwo eziningi ezinhle kakhulu, inqubo yayo yokulungiselela iyinkimbinkimbi futhi izindleko ziphakeme. Ngakho-ke, lapho ukhetha izingxenye zesakhiwo, kubalulekile ukwenza ukuhweba kanye nokuhweba ngokwezidingo zangempela kanye nezimo zomnotho.
Ukuqhathanisa ukusebenza okuphelele:
Ekukhetheni izingxenye zesakhiwo, kuyadingeka futhi ukwenza ukuqhathanisa okuphelele kwezakhiwo eziphelele zezinto. Ngaphezu kwamandla okucindezela, kuyadingeka futhi ukucabangela amandla okuthamba, amandla okucheba, ukuqina, ukumelana nokugqwala, ukuzinza kokushisa kanye nezinye izakhiwo zezinto. Izingxenye zegranite eziqondile zinhle kakhulu emandleni okucindezela nokuqina, kodwa zimbi kakhulu ekuqineni. Izingxenye ze-ceramic eziqondile zinokushiswa okuhle kakhulu, i-coefficient yokukhulisa ukushisa ephansi kanye nokumelana nokugqwala, kodwa kunezinselele ezithile ekuqhekekeni nasekubuneni kokucubungula. Ngakho-ke, lapho ukhetha izingxenye zesakhiwo, kufanele kucatshangelwe futhi kukhethwe ngokuphelele ngokwezidingo ezithile.
Ngamafuphi, izingxenye ze-granite enembile kanye nezingxenye ze-ceramic enembile zinezinzuzo zazo ngamandla okucindezela, okunomthelela obalulekile ekukhetheni izingxenye zesakhiwo. Ekusetshenzisweni okungokoqobo, kufanele kucatshangelwe futhi kukhethwe ngokuphelele ngokwezidingo ezithile kanye nezimo ukuqinisekisa ukuphepha, ukuthembeka kanye nokucabanga okungokomnotho kwezingxenye zesakhiwo.
