Aluminiyamu imakhala ndi moyo womwe zitsulo zina zochepa zimatha kufanana.Sichita dzimbiri ndipo imatha kubwezeretsedwanso mobwerezabwereza, zomwe zimangofuna kachigawo kakang'ono ka mphamvu zomwe zimagwiritsidwa ntchito popanga chitsulo choyambirira.
Izi zimapangitsa aluminiyumu kukhala chinthu chabwino kwambiri - chopangidwanso ndikusinthidwanso kuti chikwaniritse zosowa ndi zovuta zanthawi zosiyanasiyana ndi zinthu.
Aluminium value chain
1. Migodi ya Bauxite
Kupanga aluminiyamu kumayamba ndi bauxite yaiwisi, yomwe imakhala ndi 15-25% aluminiyamu ndipo imapezeka kwambiri mu lamba kuzungulira equator.Pali pafupifupi matani 29 biliyoni a nkhokwe zodziwika bwino za bauxite ndipo pamlingo wapano wochotsa, zosungirazi zitha zaka zoposa 100.Pali, komabe, zinthu zambiri zomwe sizinapezeke zomwe zitha kupitilira zaka 250-340.
2. Kuyenga kwa aluminiyamu
Pogwiritsa ntchito njira ya Bayer, aluminiyamu (aluminium oxide) amachotsedwa mu bauxite mu makina oyeretsera.Kenako aluminiyamu imagwiritsidwa ntchito popanga chitsulo choyambirira pamlingo wa 2: 1 (matani 2 a aluminiyamu = tani 1 ya aluminiyamu).
3. Kupanga koyambirira kwa aluminiyumu
Atomu ya aluminiyamu mu aluminiyamu imalumikizidwa ndi mpweya ndipo imayenera kuthyoledwa ndi electrolysis kuti ipange zitsulo zotayidwa.Izi zimachitika m'mizere yayikulu yopanga ndipo ndi njira yopangira mphamvu yomwe imafuna magetsi ambiri.Kugwiritsa ntchito mphamvu zongowonjezedwanso ndikuwongolera mosalekeza njira zathu zopangira ndi njira yofunikira kuti tikwaniritse cholinga chathu chokhala osalowerera ndale pa moyo wathu pofika 2020.
4. Kupanga aluminiyumu
Hydro imapereka msika ndi matani opitilira 3 miliyoni a aluminiyamu yakunyumba chaka chilichonse, zomwe zimatipangitsa kukhala otsogola ogulitsa ma ingot otulutsa, ma sheet, ma alloys oyambira ndi aluminiyamu yoyera kwambiri yokhala padziko lonse lapansi.Zomwe zimagwiritsidwa ntchito kwambiri ndi aluminiyamu yoyamba ndikutulutsa, kugudubuza ndi kuponyera:
4.1 Aluminium extruding
Extrusion imalola kupanga aluminiyumu pafupifupi mtundu uliwonse womwe ungaganizire pogwiritsa ntchito mbiri zopangidwa kale kapena zosinthidwa.
4.2 Aluminium yozungulira
Chojambula cha aluminiyamu chomwe mumagwiritsa ntchito kukhitchini yanu ndi chitsanzo chabwino cha mankhwala opangidwa ndi aluminiyumu.Chifukwa cha kusungunuka kwake kwambiri, aluminiyumu imatha kukulungidwa kuchokera pa 60 cm mpaka 2 mm ndikusinthidwanso kukhala zojambulazo zoonda ngati 0.006 mm ndipo zimakhalabe zosasunthika pakuwala, kununkhira ndi kukoma.
4.3 Kutulutsa kwa Aluminium
Kupanga aloyi ndi chitsulo china kumasintha mawonekedwe a aluminiyamu, kuwonjezera mphamvu, kuwala ndi / kapena ductility.Zogulitsa zathu za casthouse, monga ma extrusion ingots, ma sheet, ma alloys oyambira, ndodo zama waya ndi aluminiyamu yoyera kwambiri, amagwiritsidwa ntchito pamagalimoto, zoyendera, nyumba, kusamutsa kutentha, zamagetsi ndi ndege.
5. Kubwezeretsanso
Kubwezeretsanso aluminiyamu kumagwiritsa ntchito 5% yokha ya mphamvu yofunikira popanga chitsulo choyambirira.Komanso, aluminiyumu sawonongeka pakubwezeretsanso ndipo pafupifupi 75% ya aluminiyumu yonse yomwe idapangidwa ikugwiritsidwabe ntchito.Cholinga chathu ndikukula mwachangu kuposa msika pakubwezeretsanso ndikukhala otsogola pagawo lobwezeretsanso matani a aluminiyamu, ndikubweza matani 1 miliyoni a aluminiyamu yowonongeka ndi ogula chaka chilichonse.
