1. Kuchera neKunyungudutsa Aruminiyamu: Kubva paMatombo kusvika paSimbi
Kugadzirwa kwearuminiyamu kunotanga nekuchera dombo rayo guru, bauxite. Bauxite, iyo yakawanda pasi rose, inotorwa nemakemikari akaomarara kuti igadzire alumina, iyo inozonyungudutswa kuti igadzire simbi yearuminiyamu kuburikidza nekuderedza electrolytic. Maitiro aya anoshandisa simba rakawanda uye anogadzira mamwe magasi ecarbon, zvichiita kuti kugadzirwa kwearuminiyamu kudiwe maererano nezvakatipoteredza uye zviwanikwa zvesimba.
Pakati pevagadziri vearuminiyamu vanotungamira pasi rose,Rio Tintouye Alcoa inoonekwa zviri pachena. Rio Tinto, ine muzinda wayo muUK neAustralia, ndeimwe yemakambani makuru emigodhi pasi rose uye ndiyo piyona mukugadzirwa kwealuminium ine kabhoni shoma. Alcoa, iri kuUS, yave iri mutungamiriri mukuvandudza aluminium uye kuedza kuchengetedza zvakatipoteredza, kazhinji ichishandisa simba rinogona kudzorerwa mukugadzirwa kwayo. Makambani ese ari maviri anoita basa rakakosha mukuona kuti aluminium yepamusoro inowanikwa pasi rose, izvo zvinobatsira maindasitiri akaita sekugadzira macase ealuminium.
Vagadziri vearuminiyamu vari kuramba vachinyanya kutarisisa kugadzirwa kwearuminiyamu yakasvibirira vachishandisa simba rinogona kushandiswazve kuderedza kuburitswa kwekabhoni. Aruminiyamu inogona kushandiswazve zvakanyanya, nearuminiyamu inoshandiswazve ichishandisa chete 5% yesimba rinodiwa pakugadzirwa kwekutanga. Maitiro aya ekushandisa aruminiyamu inoshandiswazve ari kuwedzera mukurumbira muindasitiri, zvichiratidza budiriro yakanaka kune vatengi vane hanya nezvakatipoteredza.
2. Kugadziriswa kweAluminium Case: Kuumba Chimiro Chakasiyana cheAluminium uye Hunhu Hwayo
Kana simbi dzealuminium dzagadzirwa, dzinotumirwa kunzvimbo dzekugadzirisa kuti dziite zvekumonera, kuburitsa, uye mamwe maitiro ekugadzirisa, dzichiagadzira kuita machira, macoil, kana ma profiles ehukuru hwakasiyana uye zvirevo. Mashandisirwo akasiyana emakesi ealuminium anoda mhando dzakasiyana dzezvinhu zvealuminium: makesi akareruka anogona kukoshesesa kudzora huremu, nepo makesi ekudzivirira anogona kushandisa aluminium yakakora kuti igare kwenguva refu.
Mamwe ema processor epamusoro ealuminium pasi rose anosanganisiraHydro, ChalcouyeNovelisHydro, kambani yekuNorway, inozivikanwa zvikuru nekuzvipira kwayo mukugadzirisa aruminiyamu inochengetedza zvakatipoteredza uye inotarisa pakugadzira aruminiyamu yemhando yepamusoro yekushandisa zvakasiyana-siyana. Chalco (China Aluminum Corporation) ikambani huru yekuChina inozivikanwa nemabasa ayo makuru ekugadzira aruminiyamu, kusanganisira kuchera, kugadzirisa, uye kudzokorodza. Novelis, inotungamira muzvigadzirwa zvearuminiyamu zvakaputirwa muUS, inotarisa zvakanyanya pakugadzirisa, ichibatsira mukugadzirwa kwezvinhu zvearuminiyamu zvemhando yepamusoro kumaindasitiri akadai semotokari, kurongedza, uye mashandisirwo akakosha, akadai semakesi earuminiyamu.
Kugadzirisa pamusoro pechinhu kwakakoshawo panguva ino. Kuisa anodizing aruminiyamu hakungobatsiri chete kuramba ngura asiwo kunowedzera chitarisiko chayo, zvichipa mavara akawanda uye kupenya. Ruzivo urwu rwekugadzirisa rune simba rakananga pahunhu hwekupedzisira uye hupenyu hwemakesi earuminiyamu.
3. Kuchinja Kwakaita Hunhu hweAluminium neMutengo weAluminum Case
Sevatengi, kunzwisisa kugadzirwa uye kugadziriswa kwearuminiyamu kunotibatsira kunzwisisa zviri nani mutengo wemakesi earuminiyamu, uye zvinotigonesawo kuita sarudzo dzine ruzivo rwakadzama pakutenga. Semuenzaniso, kusarudza mhando dzinoshandisa aruminiyamu yakadzokororwa yakasimbiswa kana zvinhu zvemhando yepamusoro hazvingovimbisi chete chigadzirwa chakanaka asiwo zvinotsigira kugadzirwa kwakakodzera nharaunda.
Muchimiro chemitengo yemakesi earuminiyamu, zvinhu zvearuminiyamu zvinomiririra chikamu chikuru. Kuchinja-chinja kwemitengo yearuminiyamu kunokanganisa zvakananga mutengo wemusika wemakesi earuminiyamu. Semuenzaniso, mitengo yearuminiyamu yepasi rose inogona kukwira zvakanyanya nekuda kwekuchinja kwekudiwa kwezvinhu kana kuchinja kwemitengo yesimba, izvo zvinonyanya kukanganisa vagadziri vemakesi vanovimba nearuminiyamu yemhando yepamusoro. Kusagadzikana kwemitengo uku kunopedzisira kwakanganisa vatengi.
4. Mafambiro Emangwana: Akasvibirira, Akareruka
Sevatengi, kunzwisisa kugadzirwa uye kugadziriswa kwearuminiyamu kunotibatsira kunzwisisa zviri nani mutengo wemakesi earuminiyamu, uye zvinotigonesawo kuita sarudzo dzine ruzivo rwakadzama pakutenga. Semuenzaniso, kusarudza mhando dzinoshandisa aruminiyamu yakadzokororwa yakasimbiswa kana zvinhu zvemhando yepamusoro hazvingovimbisi chete chigadzirwa chakanaka asiwo zvinotsigira kugadzirwa kwakakodzera nharaunda.
Muchimiro chemitengo yemakesi earuminiyamu, zvinhu zvearuminiyamu zvinomiririra chikamu chikuru. Kuchinja-chinja kwemitengo yearuminiyamu kunokanganisa zvakananga mutengo wemusika wemakesi earuminiyamu. Semuenzaniso, mitengo yearuminiyamu yepasi rose inogona kukwira zvakanyanya nekuda kwekuchinja kwekudiwa kwezvinhu kana kuchinja kwemitengo yesimba, izvo zvinonyanya kukanganisa vagadziri vemakesi vanovimba nearuminiyamu yemhando yepamusoro. Kusagadzikana kwemitengo uku kunopedzisira kwakanganisa vatengi.
