Esigabeni sesayensi yezinto ezintsha, insimbi ye-magnesium isiba into egxilwe kakhulu embonini ngenxa yokusebenza kwayo okuhle kakhulu namandla amakhulu okusebenza. Njengensimbi yesakhiwo elula kunazo zonke emhlabeni, izakhiwo eziyingqayizivele ze-magnesium ziyenza ithembise ukusetshenziswa endaweni yezindiza, ukukhiqizwa kwezimoto, izinto zikagesi, i-biomedicine neminye imikhakha.
Ubuningi bensimbi ye-magnesium cishe bungu-1.74 g/cubic centimeter, okuyingxenye eyodwa kuphela yaleyo ye-aluminium kanye nengxenye yesine yensimbi. Lesi sakhiwo esimangalisayo esingasindi senza i-magnesium ibe yinto efanelekile yemikhiqizo engasindi. Emhlabeni jikelele, ngezidingo ezikhulayo zokongiwa kwamandla kanye nokunciphisa ukungcola, le ndawo yensimbi ye-magnesium ibaluleke kakhulu abakhiqizi bezimoto kanye nezindiza.
Ngaphezu kokuba yi-lightweight, insimbi ye-magnesium futhi inamandla amahle okusebenza kanye nokuqina. Nakuba ingenamandla njenge-aluminium nensimbi, ezinhlelweni eziningi, isilinganiso samandla nesisindo se-magnesium sanele ukuhlangabezana nezidingo zokuklama. Ngaphezu kwalokho, insimbi ye-magnesium inezinto ezinhle kakhulu zokuzamazama komhlaba futhi ikwazi ukumunca ukudlidliza nomsindo, okuyivumela ukuthi inikeze ulwazi lokugibela olunethezekile lapho kukhiqizwa umzimba nezakhi zesakhiwo sezimoto ezisebenza kahle nezindiza.
Insimbi ye-Magnesium iphinda ibonise ukuguquguquka okuhle kwe-thermal kanye nogesi, izakhiwo eziyenza idume kakhulu ku-electronics, njengasebhokisini lezinto ezisetshenziswayo ezifana namakhompyutha aphathekayo, omakhalekhukhwini, namakhamera. Izici zokukhipha ukushisa ze-magnesium alloy zisiza okokusebenza kwe-elekthronikhi ukugcina amazinga okushisa aphansi ngesikhathi sokusebenza kwesikhathi eside, ngaleyo ndlela andise impilo yesevisi yomkhiqizo.
Ngokwezakhiwo zamakhemikhali, insimbi ye-magnesium inomsebenzi wamakhemikhali ophezulu. Ihlangana nomoya-mpilo emoyeni ekamelweni lokushisa ukuze yakhe ifilimu ye-oxide eminyene. Le filimu ye-oxide ingavikela i-magnesium yangaphakathi ukuthi ingaqhubeki nokusabela nge-oxygen, ngaleyo ndlela inikeze Okunye ukumelana nokugqwala. Kodwa-ke, ngenxa yomsebenzi wamakhemikhali e-magnesium, ukumelana nokugqwala kwayo ezindaweni ezinomswakama akukuhle njengalokho kwe-aluminium nensimbi. Ngakho-ke, ekusetshenzisweni okungokoqobo, ubuchwepheshe bokwelapha obungaphezulu buvame ukusetshenziselwa ukuthuthukisa ukumelana nokugqwala.
Kuhle ukusho ukuthi insimbi ye-magnesium iphinde ibonise amandla amakhulu emkhakheni wezokwelapha. Njengoba i-magnesium ingenye yezinto ezibalulekile zokulandela umkhondo emzimbeni womuntu futhi inokuvumelana okuhle kwe-biocompatibility kanye ne-biodegradability, abacwaningi bahlakulela izimila zezokwelapha ezisekelwe ku-magnesium, njengezinzipho zamathambo nama-scaffolds, ezinganciphisa kancane kancane, ngaleyo ndlela zinciphise isidingo sokuhlinzwa kwesibili ukuze kususwe. ukufakelwa.
Nokho, ukusetshenziswa kwensimbi ye-magnesium nakho kubhekana nezinselele. Ukuvutha kwe-magnesium kuyisici sokuphepha okufanele sicatshangelwe lapho sisetshenziswa, ikakhulukazi ngaphansi kwezimo ezithile ezifana namazinga okushisa aphezulu noma ukugaya, lapho uthuli lwe-magnesium lungabangela imililo noma ukuqhuma. Ngakho-ke, izinyathelo zokuphepha eziqinile ziyadingeka lapho uphatha futhi ucubungula insimbi ye-magnesium.
Ngokuthuthuka kobuchwepheshe, ubuchwepheshe bokucubungula bensimbi ye-magnesium nabo buthuthuka njalo. Isibonelo, ukumelana nokugqwala nokumelana nokugqokwa kwensimbi ye-magnesium kungathuthukiswa kakhulu ngokusebenzisa ubuchwepheshe be-alloy obusezingeni eliphezulu kanye nobuchwepheshe bokwelashwa kwendawo. Ngasikhathi sinye, abacwaningi basebenza kanzima futhi ukuthuthukisa ama-alloys amasha asuselwa ku-magnesium ukuze bathuthukise izakhiwo zabo zizonke futhi bandise ububanzi bezicelo zabo.
Kafushane, insimbi ye-magnesium isiba inkanyezi emkhakheni wesayensi yezinto ngenxa yesisindo sayo esilula, amandla aphezulu, izici ezinhle kakhulu ze-thermal kanye ne-electrical conductivity, kanye nokuvikelwa kwemvelo namandla e-biomedical emikhakheni ethile. Ngokuqamba okusha okuqhubekayo kokukhiqiza nokucubungula ubuchwepheshe, sinesizathu sokukholelwa ukuthi insimbi ye-magnesium izodlala indima ebaluleke kakhulu ekusetshenzisweni kwezinto ezibonakalayo esikhathini esizayo.
