Izindaba

I-Aluminium igqama phakathi kwezinye izinsimbi ngomjikelezo wayo wokuphila ongenakuqhathaniswa. Ukumelana nokugqwala kwayo kanye nokugaywa kabusha kwenza ihluke, njengoba ingasetshenziswa kabusha izikhathi eziningi ngokusetshenziswa kwamandla okuphansi kakhulu uma kuqhathaniswa nokukhiqizwa kwensimbi engakazalwa. Kusukela ekuqaleni kwezimayini ze-bauxite kuya ekwakhiweni kwemikhiqizo eyenziwe ngokwezifiso kanye nezinqubo zokuphinda zigaywe kabusha, inkampani yethu ehlanganiswe ngokugcwele ye-aluminium idala inani kuwo wonke umjikelezo.

Aluminium value chain

1. Imayini ye-bauxite

Inqubo yokukhiqiza i-aluminium isuka ekumbiweni kwe-bauxite, insimbi equkethe cishe u-15-25% we-aluminium futhi itholakala kakhulu ezifundeni eziseduze nenkabazwe. Njengamanje, kunezindawo ezigciniwe ezilinganiselwe zamathani ayizigidi eziyizinkulungwane ezingama-29 e-bauxite engakwazi ukuqhubeka nokumba iminyaka engaphezu kwekhulu ngokwezinga lamanje. Ngaphezu kwalokho, ukuba khona kwezinsiza ezingakatholwa kuphakamisa amandla okunweba lesi sikhathi sibe yiminyaka engama-250-340.

2. Ukucwengwa kwe-alumina

Kusetshenziswa inqubo ye-Bayer, i-alumina (i-aluminium oxide) ikhishwa ku-bauxite endaweni yokucwenga. I-alumina ibe isisetshenziswa ukukhiqiza insimbi eyinhloko ngesilinganiso esingu-2:1 (amathani ama-2 e-alumina = ithani elingu-1 le-aluminium).

3. Ukukhiqizwa kwe-aluminium okuyinhloko

Ukuze kukhiqizwe insimbi ye-aluminium, isibopho samakhemikhali phakathi kwe-aluminium nomoya-mpilo ku-alumina sidinga ukugqashuka nge-electrolysis. Lena inqubo edinga amandla kakhulu eyenzeka ezindaweni zokukhiqiza ezinkulu, ezidinga inani elikhulu likagesi. Ukuze sifinyelele umgomo wethu wokungathathi hlangothi kwekhabhoni ngokombono womjikelezo wempilo ngo-2020, kubalulekile ukusebenzisa imithombo yamandla avuselelekayo futhi sithuthukise izindlela zethu zokukhiqiza.

4. Ukwenziwa kwe-Aluminium

Ukucutshungulwa kwe-aluminium kuyinqubo lapho izinto ze-aluminium zicutshungulwa futhi ziphathwe ngochungechunge lwezinqubo zokukhiqiza imikhiqizo ehlukahlukene ye-aluminium. Izinyathelo eziyinhloko zihlanganisa ukukhipha, ukugoqa kanye nokusakaza. I-Extrusion idala ingcindezi ngokudlulisa okubalulekile kwe-aluminiyamu ku-die ku-extruder, iyikhiphele kwinto enomumo odingekayo we-cross-sectional. Le ndlela ifanele ukukhiqiza imikhiqizo emise okuyinkimbinkimbi njengeamafasitela ozimele, amafreyimu eminyango namapayipi. Ukugingqa ukudlulisa amabhulokhi e-aluminium noma amapuleti ochungechungeni lwezinqubo zokugingqika ngomshini wokuwacubungula abe ukujiya nobubanzi obudingekayo. Le ndlela ilungele ukukhiqizwa kwemikhiqizo efana ne-aluminium foil, amashidi e-aluminium alloy namabhodlela e-aluminium. Ukulingisa kuhlanganisa ukuthela i-aluminium encibilikisiwe esikhunjeni, esibese sipholiswa futhi siqiniswe ukuze sakhe umumo womkhiqizo ofunekayo. Le ndlela ilungele ukukhiqiza amagiya e-aluminium, izingxenye zenjini, nezingxenye zezimoto, phakathi kokunye. Ngalezi zinyathelo zokucubungula, izinto ze-aluminium zingacutshungulwa ngokunembile zibe yizinhlobonhlobo zemikhiqizo ye-aluminium esebenzisa okuhlukile.

5. Ukugaywa kabusha

Ukugaywa kabusha kwe-aluminiyamu konga amandla ngendlela emangalisayo, kusebenzisa kuphela u-5% wamandla adingekayo ukuze kukhiqizwe i-aluminium eyinhloko ngezinto ezingavuthiwe. Ngaphezu kwalokho, inqubo yokugaywa kabusha kwe-aluminium ayiyehlisi ikhwalithi yayo, ivumela ukuthi iphinde isetshenziswe unomphela. Eqinisweni, ama-75% ahlaba umxhwele ayo yonke i-aluminium eyake yakhiqizwa isasebenza nanamuhla. Lezi zibalo zigqamisa ukusimama nokuhlala isikhathi eside kwe-aluminium njengento engaphinda isetshenziswe ezimbonini ezihlukahlukene.

I-Ruiqifeng ingahlinzeka ngemikhiqizo ehlukahlukene ye-aluminium ukuze ihlangabezane nezidingo zakho. Uma ungathanda ukukhuluma nethimba lethu futhi ufunde kabanzi mayelana nokuthi i-Ruiqifeng ingalizuzisa kanjani ibhizinisi lakho, zizwe ukhululekileXhumana nathi.
