Eminyakeni yamuva nje, ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuthuthukiswa kwesidingo sabathengi sekhwalithi yomkhiqizo, ukukhethwa kwezinto zokwakha zensimbi sekuphenduke isihloko esishisayo ekukhiqizeni izimboni kanye nempilo yasekhaya. Insimbi engagqwali kanye ne-aluminium alloys ivame ukuthandwa ngabakhiqizi nabathengi ngenxa yezindawo zabo eziyingqayizivele kanye nezinzuzo. Ngakho-ke yimuphi umehluko nokufana phakathi kwalezi zinto ezimbili? Iyiphi efaneleka kakhulu ezimeni zohlelo lokusebenza ezahlukene? Lesi sihloko sinikeza ukuhlaziywa okuqhathanisayo kokusebenza kwazo, ukufaneleka kanye nokusimama.
Izinzuzo nezici zensimbi engagqwali
Insimbi engagqwali iyinsimbi eyingxubevange eyakhiwe ngokuyinhloko ngensimbi, i-chromium, i-nickel nezinye izakhi, futhi isetshenziswa kakhulu ku-kitchenware, ukwakhiwa, ezezimoto nezinye izinkambu ngenxa yokumelana kwayo nokugqwala okuhle kakhulu. Amandla ayo aphezulu kanye nokumelana nemihuzuko kuyenza ikwazi ukugcina ukubukeka kwayo nokuzinza kwesakhiwo isikhathi eside, okuyenza ifanelekele izinhlelo zokusebenza ezingaphansi kwengcindezi ephezulu noma izindawo ezimanzi. Ngaphezu kwalokho, insimbi engagqwali inesiphetho esiphezulu futhi kulula ukuyihlanza, okuyenza idume ikakhulukazi ezimbonini ezidinga izindinganiso eziphakeme zokuhlanzeka, njengokucubungula ukudla kanye nemishini yezokwelapha.
Nokho, ukuminyana okuphezulu kwensimbi engagqwali kusho ukuthi isindayo uma kuqhathaniswa. Lesi sici sensimbi engagqwali singaba umkhawulo ezimbonini ezithile ezidinga imiklamo engasindi.
Izinzuzo nezici ze-aluminium alloys
Inzuzo enkulu yama-alloys e-aluminium ngaphezu kwensimbi engagqwali izakhiwo zawo ezingasindi. Ama-alloys e-aluminium ngokuvamile acishe abe izingxenye ezimbili kwezintathu elula kunensimbi engagqwali, okuwenza abe into ebalulekile ezimbonini ezifana ne-aerospace nokukhiqiza izimoto, lapho kufunwa ukusebenza okuphezulu nesisindo esilula. I-aluminium alloys ayinamandla kuphela, kodwa futhi i-ductile, okwenza kube lula umshini ezingxenyeni eziyinkimbinkimbi zesakhiwo.
Ngaphezu kwalokho, ama-alloys e-aluminium aphinde aphumelele ekumelaneni nokugqwala, ikakhulukazi ngokwelashwa kwe-anodic oxidation, okuvimbela ngokuphumelelayo i-oxidation futhi andise impilo yesevisi. Ama-alloys e-aluminium nawo aphakeme kakhulu kunensimbi engagqwali ngokuya nge-thermal conductivity, yingakho asetshenziswa kakhulu emikhiqizweni edinga ukuchithwa kokushisa okusebenzayo, njengezindlu zemishini ye-elekthronikhi namasinki okushisa.
Ukusimama kanye nezinketho zesikhathi esizayo
Uma kukhulunywa ngokusimama, ama-alloys e-aluminium anezinzuzo ezicacile zokugaywa kabusha. I-Aluminium inezinga lokugaywa kabusha elingaphezu kuka-95%, kuyilapho insimbi engagqwali inenani eliphezulu lokugaywa kabusha. Zombili zihambisana nomnotho wanamuhla wezemvelo kanye nekhabhoni ephansi, kodwa ukuminyana okuphansi kwe-aluminium kusho ukuthi isebenzisa amandla amancane uma kuqhathaniswa nokuthutha nokwenza, okuqhubekisela phambili ukuncintisana kwayo kwezemvelo.
Kafushane, insimbi engagqwali kanye nama-alloys e-aluminium anezinzuzo kanye nokubi. Insimbi engagqwali ifaneleka emikhiqizweni edinga amandla nokumelana nokugqwala, kuyilapho ama-alloys e-aluminium enenzuzo kakhulu ezinhlelweni ezingasindi nezifuna ukushisa. Abakhiqizi badinga ukukala ukusebenza nezindleko zakho kokubili lapho bekhetha izinto zokusebenza zezinhlelo ezithile zokusebenza ukuze bathole imiphumela yomkhiqizo ehamba phambili.
