Kugwiritsa ntchitodziko lapansiPoponya aluminium alnoy adachitika kale. Ngakhale China idayamba kafukufuku komanso kugwiritsa ntchito mbali imeneyi m'zaka za m'ma 1960, zakhala zikukula mwachangu. Ntchito zambiri zachitika chifukwa cha kafukufuku wofufuza wogwiritsa ntchito, ndipo zidachitika. Zipangizo zopepuka, zowoneka bwino zachilengedwe za hydrogen zosungira, ndi zina zambiri.
◆ Njira yamagetsi yoyendera dziko lapansi ku Aluminiyamu ndi aluminium aloy ◆ ◆
Dziko Lonse Lalikulu lili ndi ntchito yayikulu yamankhwala, kuthekera kotsika ndi malo apadera a Electron, ndipo kumatha kulumikizana ndi zinthu zonse zomwe zimagwiritsidwa ntchito kawiriLanthanum) Ce (ceum) Y (YNTrium) ndi sc (sinandium). Nthawi zambiri amawonjezeredwa m'madzi a aluminiyumu amadzi ndi ma firefiers, othandizira azogulitsa ndi othandizira kusungunuka, kukonza mawonekedwe, kukonzanso tirigu, ndi zina zambiri.
01Kuyeretsa Dziko Lonse
Monga kuchuluka kwa mpweya ndi ma hydrogen, makamaka hydrogen, oxygen ndi nayitrogeni) adzapangika ndikuponyera (onani Chithunzi 1a) Aluminiyamu, kuchepetsa kwa kuchuluka kwa penale ndi mawonekedwe 1b), ndikuchepetsa ma hydrogen omwe ali ndi ma hydrogen, omwe ali ndi nitrogeni. Mafuta, omwe amachotsedwa bwino mu mawonekedwe a slag mu njira yosungunulira, kuti ikwaniritse cholinga choyeretsa madzi a aluminiyamu.
Kuchita kwatsimikizira kuti dziko lapansi kuli ndi mphamvu yochepetsera zomwe zili hydrogen, oxygen ndi sulufule mu aluminium ndi aluminiyamu. Onjezerani 0.1% ~ 0.3% Revinium Madzimadzi amathandiza kusiya zonyansa zokhala ndi zonunkhira bwino; Kuphatikiza apo, zomwe zimadziwika kuti ndi zonyansa, komanso zokhazikika, ndipo zimatha kuyandama kuti mupange slag Ndipo kuchotsedwa, ndikuyeretsa mafuta a aluminiyamu madzi; tinthu tating'onoting'ono tokhala zikhale zaphokoso kwambiri za aluminium kukonza mbewu.

Pambuyo poti kuwonjezera dziko lapansi za (Al) Gawo la (Al) adayamba kukhala ocheperako, omwe adasinthiratu kuti atuluke kwambiri Mtagamorphism, ndipo pokhapokha ngati ikusungidwa pamtunda wautali kwa nthawi yayitali, dziko lapansi laikulu lidzasewera kwambiri ku metamorphissism.in kuwonjezera, zomwe zimapangitsa kuti dziko lapansi likhale loti dziko lapansi lizisintha.
03 Mphamvu ya Microrualrogration of Laily
Padziko lapansi kwambiri padziko lapansi makamaka aluminium ndi aluminiyamu onjezerani mitundu itatu: malire olimbikitsa am'mimba, njira yachiwiri yolimbikitsira ndi gawo lachiwiri la mankhwala osowa padziko lapansi.
Mtundu wopezeka wa dziko lapansi wa aluminiyamu ndi aluminium aloy amagwirizana kwambiri ndi kuchuluka kwake. Nthawi zambiri, mukakhala osakwana 0.1%, gawo la nthawi yabwino kwambiri ndi materite zomwe zimatulutsa kukula kwa micro monga gawo lachiwiri likulimbikitsidwa.
