1 Gicurasi 2026 - Guhanga udushya mu ikoranabuhanga byabaye imbaraga nyamukuru mu guhindura no kuvugurura inganda za alumina ku isi, kuko abakora bibanda ku guteza imbere ibicuruzwa bifite imikorere myiza kandi byihariye kugira ngo bihuze n’ibyo porogaramu zikenera. Kuva ku bikorwa bigezweho kugeza ku bikorwa bishya, iterambere mu ikoranabuhanga ririmo gufungura amahirwe mashya yo gukura no kuvugurura imiterere y’inganda, nk’uko raporo iherutse gukorwa na Future Market Insights, Inc ibigaragaza.
Imiterere yihariye ya alumina ikora neza, harimo n'ubuso bwayo bunini, ingano y'imyenge ishobora guhindurwa, hamwe n'ubushyuhe bwo hejuru, bituma iba ibikoresho bifite uburyo bwinshi bwo kuyikoresha mu kuyishyira mu kirere, kuyikoresha mu gukamura no kuyimisha. Ariko, kwiyongera k'ubusabe bw'imikorere myiza, gukoresha ingufu nke, no kuvugurura ibisubizo birambye byatumye abakora ibicuruzwa bashora imari nyinshi mu bushakashatsi no mu iterambere (R&D), bigatuma habaho iterambere rikomeye mu ikoranabuhanga mu gukora no mu bipimo by'ibicuruzwa.
Imwe mu ntambwe zikomeye zatewe mu ikoranabuhanga mu myaka ya vuba aha ni iterambere rya alumina ikoresha ubuziranenge bwinshi ifite umwanda muto cyane. Ibicuruzwa bya alumina ikoresha ubuziranenge akenshi biba birimo umwanda muto nka icyuma, sodiyumu, na silikoni, bishobora kugira ingaruka ku mikorere yabyo mu bikorwa byo mu rwego rwo hejuru nk'ibikoresho by'ikoranabuhanga na bateri za lithiamu-ion. Kugira ngo ibi bikemuke, abakora ibikoresho bakoze ikoranabuhanga rigezweho ryo gutunganya imyanda mu byuma kugira ngo bagabanye umwanda w'icyuma kugeza kuri 10 ppm, byujuje ibisabwa bikomeye n'inganda z'ikoranabuhanga na semiconductor. Urugero, Evonik Corporation yaguriye ikigo cyayo cyo gukora okiside ya aluminiyumu mu Buyapani, yibanda ku iterambere rya alumina ikoresha ubuziranenge bwinshi kuri bateri za lithiamu-ion zikoresha ubuziranenge bwinshi, ibi bikaba bisaba kugenzura neza ingano y'uduce (D50 = 0.8–1.2 μm) na 振实密度 (≥1.0 g/cm³).
Indi ntambwe ikomeye mu ikoranabuhanga ni ugukora neza inzira zo gukora kugira ngo hongerwe ingufu zikoreshwa neza no kugabanya ingaruka ku bidukikije. Uburyo busanzwe bwo gukora alumina irimo calcination ikoresha ubushyuhe bwinshi, ikoresha ingufu nyinshi kandi igasohora imyuka ihumanya ikirere. Mu rwego rwo gusubiza ibyo, abakora bakoresheje ikoranabuhanga rigezweho nka calcination ikoresheje ubwenge bwa AI na spray granulation molding kugira ngo bongere uburyo bwo gukora. Calcination ikoresheje ubwenge bwa AI ikoresha uburyo bugezweho bwo kumenya imashini kugira ngo igenzure neza ubushyuhe, igihe, n'ibindi bipimo, ikongera ubwiza bw'ibicuruzwa kandi igabanya ikoreshwa ry'ingufu kugeza kuri 15%. Ku rundi ruhande, spray granulation molding ituma habaho uduce twa alumina dufite uburebure bumwe kandi dufite imbaraga nyinshi, dukoreshwa cyane mu bikorwa byo gutwara catalyst na bateri.
Uretse kunoza imikorere, iterambere rya alumina ivuguruye ryafunguye inzira nshya zo kuyikoresha. Mu guhindura imiterere y’ubuso bwa alumina ivuguruye binyuze mu gutera imiti ivanze n’ibintu nka silikoni, titaniyumu na zinki, abakora bongereye ubushobozi bwo kuyikoresha no guhitamo ibintu bimwe na bimwe byanduza. Urugero, Ikigo cy’Ubuhanga mu Gutunganya Ikoranabuhanga cya Akademi y’Ubumenyi bw’Abashinwa cyakoranye n’ibigo byinshi mu guteza imbere icyuma gihuza silicon na aluminiyumu, gituma imikorere yo gukuraho arseniki irushaho kuba myiza ku kigero cya 40% kandi cyakoreshejwe neza mu nganda nyinshi zitunganya amazi ku nkengero z’uruzi rwa Yangtze. Iyi alumina ivuguruye ishobora gukura arseniki mu mazi ikagera munsi ya 0.005 mg/L, yujuje ibisabwa ku rwego rw’isi mu mazi yo kunywa.
Izamuka ry’ikoreshwa ry’ibikoresho bishya ryanatumye habaho udushya mu ikoranabuhanga mu nganda za alumina zikora. Gusukura imyuka ya hydrogen, gufata no kubika karubone (CCS), no gusukura umwuka ni bimwe mu nzego zikura vuba, buri imwe ikenera ibikoresho byihariye bya alumina bikora bifite imiterere yihariye. Mu gutunganya imyuka ya hydrogen, alumina ikora ikoreshwa mu gukuraho ubushuhe n’ibinyabutabire bya sulfure muri hydrogen, bigamije kwemeza ko ikoreshwa rya lisansi rikenewe. Biteganijwe ko icyifuzo cy’imyuka ya hydrogen isukuye ku isi kiziyongera mu myaka iri imbere, inganda zirimo gukora ibikoresho bya alumina bikora neza kandi bifite ubushobozi bwo guhitamo neza ibikenewe. Urugero, isosiyete ikomeye ku isi mu bikoresho byatangije urwego rwa alumina ikora neza mu Gushyingo 2025, by’umwihariko yagenewe ibikorwa byo gutunganya no gutunganya gazi muri Amerika y’Amajyaruguru, itanga uburyo bwo kunoza uburyo bwo kuyikoresha no kugabanya ikiguzi cy’imikorere.
Mu rwego rwa CCS, alumina irimo gukoreshwa irimo gusuzumwa ku bushobozi bwayo bwo gufata dioxyde de carbone iva mu myuka ihumanya ikirere yo mu nganda. Ubushobozi bwayo bwo kuyungurura cyane no kudahindagurika kw'ubushyuhe bituma iba ibikoresho byiza byo gufata CO₂, kandi abashakashatsi barimo gukora ku guhindura imiterere y'ubuso bwayo kugira ngo bongere ubushobozi bwo guhitamo CO₂. Ubushakashatsi buherutse gukorwa na Future Market Insights bwerekana ko icyifuzo cya alumina irimo gukoreshwa mu bikorwa bya CCS cyitezwe kwiyongera ku kigero cya CAGR kirenga 8% kuva mu 2025 kugeza mu 2035, mu gihe za leta n'ibigo ku isi bikomeje gushyira imbaraga mu kugabanya imyuka ihumanya ikirere.
Urwego rutunganya umwuka ni irindi soko ririmo kuzamuka rya alumina ikora, cyane cyane mu turere dufite umwuka wanduye cyane. Alumina ikora ishobora kwinjiza neza ibintu bihumanya ikirere (VOCs), dioxyde de sulfur (SO₂), n'indi myuka yangiza, bigatuma iba ibikoresho byiza byo gutunganya umwuka. Bitewe n'ubwiza bw'umwuka wo mu nzu no hanze, abakora ibikoresho barimo gukora filters z'umwuka zikoresha alumina zifite ubushobozi bwo kuyungurura umwuka kandi zimara igihe kirekire, zigakoreshwa mu nganda no mu ngo.
Imiterere y’irushanwa ry’inganda za alumina zikora iragenda ihinduka bitewe n’udushya mu ikoranabuhanga, aho ibigo bikomeye bishora imari nyinshi mu bushakashatsi no guteza imbere ibikorwa kugira ngo bikomeze ku isoko ryabyo. Dukurikije amakuru aturuka mu biro bishinzwe umutungo bwite mu by’ubwenge mu Bushinwa, umubare w’ipatanti zemewe zijyanye na alumina zikora wiyongereye ku kigero cya 22.5% buri mwaka hagati ya 2020 na 2024, aho 70% by’izi patenti zifitwe n’ibigo bitanu bya mbere. Abakinnyi bakomeye ku isoko mpuzamahanga, barimo BASF (Ubudage), Honeywell International Inc. (US), Sumitomo Chemical Co., Ltd. (Ubuyapani), na Chinalco (Ubushinwa), barimo kwibanda ku guteza imbere ibicuruzwa byihariye no kwagura ubwiza bwabyo ku isi binyuze mu guhuza no kugura.
Muri Mutarama 2026, ikigo gikomeye ku isi gishinzwe imiti gikorera mu Buyapani cyashyizeho ubwoko bushya bw'ibintu bitera alumina bikoreshwa mu kirere kinini, byagenewe igihe kirekire cyo kongera kuvugurura no kunoza imikorere mu bijyanye no kubura umwuka uhagije no gutunganya peteroli. Iki gicuruzwa gishya kigabanya inshuro zo kongera kuvugurura, kigabanya ikiguzi cy'imikorere ku bakoresha inganda no kunoza imikorere muri rusange. Mu buryo nk'ubwo, mu ntangiriro za 2025, ikigo gikomeye gishinzwe kugabanya kuzura cyagurishije alumina nshya ifite ubushobozi bwo gukuraho arsenic, kigamije kugabanya amazi mu mijyi no mu nganda muri Amerika ya Ruguru na Aziya y'Amajyepfo.
Nubwo hari intambwe ikomeye mu guhanga udushya mu ikoranabuhanga, inganda za alumina zirimo gukora ziracyafite imbogamizi nyinshi, harimo ikiguzi kinini cy’ubushakashatsi n’iterambere, uburyo bwo kwagura ikoranabuhanga rishya, ndetse no gukenera kuzuza ibisabwa n’amategeko atandukanye mu turere dutandukanye. Ariko, gukenera ibikoresho birambye kandi bikora neza byitezwe ko bizatera ishoramari rikomeje mu bushakashatsi n’iterambere, biganisha ku iterambere ry’ikoranabuhanga.
“Guhanga udushya mu ikoranabuhanga ni ingenzi mu gufungura ubushobozi bwose bwa alumina ikora neza,” ibi byavuzwe na Nikhil Kait Wade, Visi Perezida wungirije muri Future Market Insights. “Uko inganda zikomeza gutera imbere, icyifuzo cy’ibicuruzwa byihariye kandi bifite imikorere myiza kiziyongera, kandi abakora imari mu bushakashatsi no mu iterambere kandi bakira udushya bazaba bafite umwanya mwiza wo kubyaza umusaruro amahirwe yo kwiyongera kw’isoko.”
Mu gihe urebye imbere, inganda za alumina zikora neza zitezweho gutera imbere mu ikoranabuhanga, hibandwa ku nganda zikora ku buryo butangiza ibidukikije, guhindura ibicuruzwa, no guteza imbere porogaramu nshya. Guhuza ikoranabuhanga rya digitale nka AI na IoT mu musaruro nabyo byitezweho kunoza imikorere no kugabanya ikiguzi, biganisha inganda ku hazaza harambye kandi heza. Bitewe n'imiterere yazo inyuranye hamwe n'uburyo zikoresha zigenda ziyongera, alumina ikora neza igiye kugira uruhare runini mu mpinduka ku isi yose igana ku rusobe rw'inganda rusukuye kandi rurambye.
