1. Ukwembiwa kunye nokuNyibilikisa iAluminiyam: Ukusuka kwintsimbi ekrwada ukuya kwiNtsimbi
Ukuveliswa kwe-aluminiyam kuqala ngokumbiwa kwentsimbi yokuqala, i-bauxite. I-Bauxite, eninzi kwihlabathi jikelele, ingena kwinkqubo yokutsalwa kweekhemikhali ezintsonkothileyo ukuvelisa i-alumina, ethi ke inyibilikiswe ukuvelisa isinyithi se-aluminiyam ngokunciphisa i-electrolytic. Le nkqubo inamandla kakhulu kwaye ivelisa ukukhutshwa kwekhabhoni, okwenza imveliso ye-aluminiyam ibe nzima ngokwendalo kunye nemithombo yamandla.
Phakathi kwabavelisi be-aluminium abahamba phambili kwihlabathi,eRio Tintokunye ne-Alcoa ivelele. I-Rio Tinto, ikomkhulu lase-UK nase-Australia, yenye yeenkampani zemigodi ezinkulu kwihlabathi jikelele kwaye inguvulindlela ekuveliseni i-aluminiyam enekhabhoni ephantsi. I-Alcoa, esekelwe e-US, ibe yinkokeli kwi-aluminium innovation kunye nemigudu yokuzinza, ehlala isebenzisa imithombo yamandla evuselelekayo kwiinkqubo zayo zokuvelisa. Zombini iinkampani zidlala indima ebalulekileyo ekuqinisekiseni unikezelo lwe-aluminiyam ekumgangatho ophezulu kwihlabathi jikelele, olunceda imizi-mveliso efana nokwenza i-aluminium case.
Ukwandisa, abavelisi be-aluminium bagxile kwimveliso ye-aluminium eluhlaza ngokusebenzisa amandla ahlaziyekayo ukunciphisa ukukhutshwa kwekhabhoni. I-aluminiyam iphinda isetyenziswe kakhulu, kwaye i-aluminiyam esetyenzisiweyo isebenzisa kuphela malunga ne-5% yamandla afunekayo kwimveliso yokuqala. Lo mkhwa obhekiselele kwi-aluminiyam esetyenzisiweyo ifumana amandla kwishishini, ebonisa uphuhliso oluhle kubathengi abakhathalela indalo.
2. UkuLungiswa kweAluminiyam: Ukubumba iFomu yeAluminiyam ekhethekileyo kunye neePropati
Nje ukuba ii-ingots ze-aluminiyam zivelisiwe, zithunyelwa kwiindawo zokusetyenzwa ukuze ziye kuqengqeleka, zigqithiswe, kunye nezinye iinkqubo zonyango, zizenze zibe ngamashiti, iikhoyili, okanye iiprofayili zobukhulu obahlukeneyo kunye neenkcukacha. Ukusetyenziswa okwahlukeneyo kweemeko ze-aluminiyam zifuna iintlobo ezahlukeneyo zezixhobo ze-aluminium: iimeko ezilula zinokuthi zibeke phambili ukulawulwa kobunzima, ngelixa iimeko zokukhusela zingasebenzisa i-aluminiyam eninzi ukuqina okongeziweyo.
Ezinye zeeprosesa eziphezulu ze-aluminium zehlabathi zibandakanyaHydro, Chalco, kwayeIinoveli. I-Hydro, inkampani yaseNorway, ithathwa kakuhle ngokuzibophelela kwayo kwizisombululo ze-aluminium ezizinzileyo kwaye igxile ekuveliseni umgangatho ophezulu we-aluminium kwizicelo ezahlukeneyo. I-Chalco (i-China Aluminiyam Corporation) ngumvelisi omkhulu waseTshayina owaziwayo ngemisebenzi yayo eyandisiweyo ye-aluminium, kuquka imigodi, ukusetyenzwa, kunye nokuphinda kusetyenziswe. I-Novelis, inkokeli esekelwe e-US kwimveliso ye-aluminium eqengqelekayo, igxininise kakhulu ekusetyenzisweni kwakhona, igalelo kwimveliso ezinzileyo yezinto eziphezulu ze-aluminium kumashishini afana neemoto, ukupakisha, kunye nezicelo ezizodwa, ezifana neemeko ze-aluminium.
Unyango lomphezulu nalo lubalulekile kweli nqanaba. I-aluminiyam yeAnodizing ayiphuculi kuphela ukuxhathisa ukubola kodwa iphucula inkangeleko yayo, inika umbala othe kratya kunye nokhetho oluqaqambileyo. Ezi nkcukacha zokucubungula zinefuthe elithe ngqo kumgangatho wokugqibela kunye nobomi beemeko ze-aluminium.
3. Indlela iAluminiyam esemgangathweni kunye neendleko ezichaphazela ngayo amaxabiso eCase
Njengabathengi, ukuqonda ukuveliswa kunye nokulungiswa kwe-aluminiyam kusinceda siqonde ngcono ukwakhiwa kweendleko zeemeko ze-aluminium, kwaye kusenza sikwazi ukwenza ukhetho olunolwazi xa sithenga. Umzekelo, ukukhetha iibrendi ezisebenzisa i-aluminium eqinisekisiweyo ehlaziyiweyo okanye izinto ezikumgangatho ophezulu aziqinisekisi kuphela imveliso ephezulu kodwa zixhasa imveliso enoxanduva lokusingqongileyo.
Kwixabiso leendleko zeemeko ze-aluminium, izinto ze-aluminium zimela umlinganiselo omkhulu. Ukuguquguquka kwamaxabiso e-aluminium kuchaphazela ngokuthe ngqo ixabiso lemarike yeemeko ze-aluminium. Umzekelo, amaxabiso e-aluminiyam yehlabathi anokunyuka ngokukhawuleza ngenxa yotshintsho lwemfuno yobonelelo okanye ukutshintshwa kwexabiso lamandla, okunempembelelo ngakumbi kubavelisi betyala abaxhomekeke kwi-aluminiyam ekumgangatho ophezulu. Oku kuguquguquka kwexabiso ekugqibeleni kuchaphazela abathengi.
4. IiNdlela zekamva: Iluhlaza, iKhaphukhaphu
Njengabathengi, ukuqonda ukuveliswa kunye nokulungiswa kwe-aluminiyam kusinceda siqonde ngcono ukwakhiwa kweendleko zeemeko ze-aluminium, kwaye kusenza sikwazi ukwenza ukhetho olunolwazi xa sithenga. Umzekelo, ukukhetha iibrendi ezisebenzisa i-aluminium eqinisekisiweyo ehlaziyiweyo okanye izinto ezikumgangatho ophezulu aziqinisekisi kuphela imveliso ephezulu kodwa zixhasa imveliso enoxanduva lokusingqongileyo.
Kwixabiso leendleko zeemeko ze-aluminium, izinto ze-aluminium zimela umlinganiselo omkhulu. Ukuguquguquka kwamaxabiso e-aluminium kuchaphazela ngokuthe ngqo ixabiso lemarike yeemeko ze-aluminium. Umzekelo, amaxabiso e-aluminiyam yehlabathi anokunyuka ngokukhawuleza ngenxa yotshintsho lwemfuno yobonelelo okanye ukutshintshwa kwexabiso lamandla, okunempembelelo ngakumbi kubavelisi betyala abaxhomekeke kwi-aluminiyam ekumgangatho ophezulu. Oku kuguquguquka kwexabiso ekugqibeleni kuchaphazela abathengi.
