I-Aluminium iyimpahla eqinile futhi elula kakhulu. Ngakho-ke, ngokuvamile isetshenziswa ezindaweni ezihlukahlukene. Kodwa kuhle kangakanani ibhalansi yemvelo yensimbi ekhanyayo? Ukusimama kanye nokuba nobungane kwezemvelo kwe-aluminium kuncike ezintweni ezihlukahlukene, okuhlanganisa ukuthi imayini, ikhiqizwa, isetshenziswa futhi igaywa kanjani kabusha.
Ukumba kanye nokukhipha i-aluminium
Uma kukhulunywa ngezimayini ze-aluminium kanye nokumba, kunezici ezithile ezithinta ukusimama
I-Bauxite iyinsimbi okukhishwa kuyo i-aluminium. Imayini ye-bauxite ingaba nomthelela emvelweni, okuhlanganisa ukucekelwa phansi kwemvelo, ukulahleka kwenhlabathi kanye nokungcoliswa kwamanzi. Izinqubo ezisimeme zihlanganisa ukugwema ukuxhashazwa ngokweqile, ukubuyisela izindawo ezinezimayini, kanye nokusebenzisa amasu okumba angayingeni imvelo.
I-Electrolysis inqubo lapho i-aluminium ikhishwa ku-aluminium oxide. Le nqubo idinga amanani abalulekile wamandla kagesi. Ukusimama lapha kuncike kakhulu emthonjeni walamandla. Uma kusetshenziswa imithombo yamandla avuselelekayo njengamandla elanga noma amanzi asetshenziswa ngamanzi, kunganciphisa kakhulu umthelela wendawo.
Ukukhiqizwa kwe-aluminiyamu okusimeme kuhilela ukusetshenziswa kahle kwezinsiza kanye nokushintshela emnothweni oyindilinga. Lokhu kusho ukuthi imikhiqizo ye-aluminium kufanele igaywe kabusha ekupheleni kwempilo yayo futhi ibuyiselwe ohlelweni lokukhiqiza.
Ukugaywa kabusha kwe-aluminium
Ukugaya kabusha i-aluminium kudinga cishe u-5% wamandla uma kuqhathaniswa nokukhiqizwa kwe-aluminium eyinhloko. Lokhu konga amandla okubalulekile kusiza ukunciphisa ukukhishwa kwe-CO2 futhi kunciphise ukusetshenziswa kwamandla sekukonke. Uma kuqhathaniswa nezinye izinsimbi, i-aluminium ifaneleka ngokukhethekile ukuthi igaywe kabusha ngoba ingagaywa kabusha ngokuphindaphindiwe ngaphandle kokulahlekelwa ikhwalithi.
Ukugaywa kabusha kwe-aluminiyamu kunciphisa inani lemfucuza egcina isendaweni yokulahla imfucumfucu. Imikhiqizo ye-aluminium esifike ekupheleni kwempilo yayo ingaqoqwa, igaywe kabusha futhi ibuyiselwe emjikelezweni wokukhiqiza esikhundleni sokuphelela kudoti. Lokhu kusebenza emikhiqizweni yakudala efana izindlu eziqinile ze-aluminium ikakhulukazi njengoba kulula ukugaywa kabusha. Okunzima kakhulu ukugaywa kabusha kwezingxenye ezisetshenziswayo.
Ukugaywa kabusha kwe-aluminium kusekela umbono womnotho oyindilinga, lapho izinsiza zisetshenziswa kahle futhi udoti uncishiswa. Ngokuqoqa nokuvuselela imikhiqizo ye-aluminium ekupheleni komjikelezo wokuphila kwayo, isidingo se-aluminium eyinhloko siyancishiswa, okubuye kunciphise ukucindezela emithonjeni yemvelo kanye nokusetshenziswa kwamandla.
Umnotho we-aluminium esimeme udinga okuhle ithuthukise ingqalasizinda yokugaywa kabusha. Lokhu kuhlanganisa izinhlelo zokuqoqwa kwe-aluminium ezilahliwe, izinsiza zokuhlunga kanye nezindawo zokugaywa kabusha ezikwazi ukugaywa kabusha kwe-aluminium ngokuphumelelayo. Ukukhuthaza nokweseka ingqalasizinda enjalo kubalulekile empumelelweni yokuvuselelwa kabusha kwe-aluminium.
Ukuhlaziywa komjikelezo wempilo, ezokuthutha kanye nezinto ezishintshayo
Ukuhlolwa okuphelele kokusimama kwe-aluminium kufanele kucabangele wonke umjikelezo wempilo, okuhlanganisa ukukhiqizwa, ukusetshenziswa nokulahlwa. Lokhu kwenza kube nokunqunywa okuphathekayo komthelela kwezemvelo.
Umthelela wemvelo ungathonywa ukuthuthwa kwemikhiqizo ye-aluminium. Imizila emide yezokuthutha ingathinta ukusimama, ikakhulukazi uma ezokuthutha kusetshenziswa izindlela ezilimaza imvelo. Ngenxa yesisindo esiphansi, ngisho nezingxenye ezinkulu, ukuthuthwa kwezingxenye ishibhile ngokuqhathaniswa, ngokwesibonelo, imishayo yensimbi.
Kwezinye izinhlelo zokusebenza, i-aluminium ingashintshwa kufakwe ezinye izinto ezingase zivumelane nemvelo. Ukukhethwa kwezinto kuncike ezidingweni ezithile zohlelo lokusebenza.
Kafushane, i-aluminium ibhekwa njengesimeme kakhulu ngenxa yokuphinda isetshenziswe kabusha nesisindo esiphansi uma iqhathaniswa nezinye izinto. Kodwa-ke, ukusimama kuthonywa kakhulu izinqubo zokukhiqiza nokugaywa kabusha kanye nokusetshenziswa nokulahlwa.

Okungashiwongo lapha ngeshwa ingozi yezempilo uma izinhlayiya ze-aluminium zingena emzimbeni ngokudla, isibonelo.
Ngokwesibonelo, kuma-capsules ekhofi, ama-ion e-aluminium akhululwa lapho yonke into ihlangana nokushisa nomhwamuko wamanzi ovela emshinini kanye nama-asidi ekhofi. Le aluminium ibe isiphelela ekhofini futhi ekugcineni kumthengi... - Le ngozi ikhona futhi namathreyi e-grill alahlwayo, amazambane abhakiwe, njll.
Ngeshwa, i-aluminium iphinde isetshenziswe njengento ethwala emithini yokugoma...
