Kodi zitsulo za aluminiyamu zimachita dzimbiri?
Amachita dzimbiri? Yankho ndi lakuti inde, aluminiyumu idzachita dzimbiri, koma dzimbiri la aluminiyamu si dzimbiri kwenikweni. Aluminiyamu sichichita dzimbiri nthawi zonse. Filimu ya aluminium oxide idzapanga pamwamba pa aluminiyumu. Kanema wa oxide uyu ndi wandiweyani komanso woteteza, zomwe zingalepheretse aluminium yamkati kuti isapitirire kuchitapo kanthu ndi mpweya, kotero aluminiyumu sangatero “dzimbiri” ngati chitsulo. Komabe, ngati filimu ya okusayidi yawonongeka, monga mchenga kapena dzimbiri lamphamvu, aluminiyumu idzawonjezera oxidize, kusonyeza mdima, kusweka, ndi zina.
Anthu ambiri amaganiza kuti aluminiyamu sichapafupi kuchita dzimbiri, koma kwenikweni aluminiyumu amakonda dzimbiri kuposa chitsulo! Komabe, aluminiyamu dzimbiri, mosiyana ndi dzimbiri lachitsulo, siliri ndi dzimbiri, ndipo pamwamba pake amaonekabe ngati chitsulo choyera-siliva.
Kodi aluminiyamu dzimbiri ndi chiyani?
Chitsulo chimachita dzimbiri chikakokedwa ndi okosijeni mumlengalenga. Aluminiyamu imakumana ndi okosijeni kupanga aluminiyamu okusayidi, chomwe ndi aluminiyamu dzimbiri. Aluminiyamu dzimbiri ndi woonda kwambiri, chigawo chimodzi chokha cha chikwi khumi cha millimeter chochindikala, koma ndizovuta kwambiri komanso zosavala. Zimamamatira pamwamba pa aluminiyumu, kuletsa aluminium mkati kuti zisakhudze mpweya wakunja, ndi kuteteza aluminium kuti isapitirire dzimbiri.
Aluminiyamu amachita dzimbiri mosavuta? Dzimbiri, monga momwe zimadziwika bwino, amatanthauza momwe chitsulo chimagwirira ntchito ndi mpweya ndi mpweya wamadzi mumpweya wonyowa kutulutsa dzimbiri (makamaka iron oxide). Izi zimapangitsa kuti chitsulo chiwonjezeke, potero kuwononga kapangidwe ndi ntchito ya chitsulo mankhwala.
Komabe, aluminiyamu ndi chitsulo ndi osiyana mankhwala. Aluminiyamu ichita dzimbiri ngati inyowa? Pamene pamwamba pa aluminiyumu amabwera kukhudzana ndi mpweya, idzachitapo kanthu mwamsanga ndi mpweya wa mumlengalenga kuti ipange filimu wandiweyani ya aluminium oxide. Izi zimachitika kaŵirikaŵiri zimatengedwa kukhala “aluminiyamu dzimbiri”. Koma kwenikweni, filimuyi pamwamba pa zotayidwa ndi zovuta kwambiri ndi dzimbiri zosagwira, ndipo imatha kuphimba mwamphamvu pamwamba pa aluminiyumu, kuletsa aluminium kuti isagwirenso ntchito ndi mpweya kapena madzi. Choncho, chowonadi ndi chakuti njira yodzitetezera iyi ya aluminiyamu imapangitsa kuti zikhale zosavuta kuchita dzimbiri ngati chitsulo.
Kodi mfundo ya dzimbiri la aluminiyamu ndi chiyani?
Aluminiyamu ndi chitsulo chogwira ntchito chomwe chimagwira ndi mpweya mumlengalenga kutentha kwa firiji. Izi zimatchedwa kuti oxidation reaction, ndipo zotsatira zake ndi wandiweyani aluminium oxide filimu pamwamba pa aluminiyumu. Filimu ya aluminium oxide iyi ndi yolimba kwambiri komanso yosachita dzimbiri. Imamamatira mwamphamvu pamwamba pa aluminiyumu, kuteteza aluminiyumu kuti asagwirizanenso ndi mpweya kapena zinthu zina zowononga, potero kuteteza zotayidwa mkati kuti makutidwe ndi okosijeni zina. Ngakhale filimu ya aluminium oxide ili ndi chitetezo chabwino pa aluminiyumu, pamikhalidwe ina yapadera, monga zokanda kapena kuwonongeka pamwamba pa aluminiyumu, kuwonetsa aluminiyumu yamkati, kapena aluminiyamu ali m'malo ovuta monga chinyezi chachikulu komanso kutentha kwakukulu kwa nthawi yayitali, zitha kuyambitsa makutidwe ndi okosijeni kwina kwa aluminiyamu, chomwe ndi chomwe timachitcha nthawi zambiri “dzimbiri la aluminiyamu”. Mfundo ya dzimbiri la aluminiyamu ndi yakuti aluminiyumu imagwira ntchito ndi mpweya mumlengalenga kuti ipange filimu yowonjezereka ya aluminium oxide.. Filimuyi imakhala ndi chitetezo chabwino pa aluminiyamu ndipo imatha kuteteza aluminium kuti isapitirire makutidwe ndi okosijeni. Komabe, pamikhalidwe ina yapadera, aluminiyamu ikhoza kupitilirabe ma oxidation reaction.
Zimatenga nthawi yayitali bwanji kuti aluminiyamu ichite dzimbiri?
Zimatenga nthawi yayitali bwanji kuti aluminiyamu ichite dzimbiri? Aluminiyamu akhoza dzimbiri, koma dzimbiri lake limachedwa. Nthawi ya dzimbiri ya aluminiyamu imakhudzidwa ndi zinthu zambiri, kuphatikizapo zinthu zachilengedwe, zinthu processing ndi zinthu ntchito. M'mikhalidwe yabwino, aluminiyamu imachita dzimbiri pang'onopang'ono, koma aluminiyumu yomwe yakhala ikukumana ndi zovuta kwa nthawi yayitali kapena yosasamalidwa bwino imatha kuchita dzimbiri.. Nthawi zambiri, m'mikhalidwe yabwino, aluminiyamu yomwe sinapangidwe mwapadera ingatenge zaka makumi kapena zaka mazana kuti iwonetse dzimbiri.
Aluminiyamu aloyi amachita dzimbiri mosavuta?
Aluminiyamu amachita dzimbiri mosavuta? Mu chilengedwe, filimu wandiweyani wa aluminiyamu oxide imapanga mwachangu pamwamba pa aluminiyumu. Kanemayu ndi wolimba kwambiri komanso wosachita dzimbiri, ndipo imatha kuteteza aluminiyumu kuti isagwirenso ntchito ndi mpweya ndi madzi, potero amateteza aluminium kuti isachite dzimbiri. Choncho, aluminiyumu ali ndi kukana kwa dzimbiri. Nthawi zambiri, aluminiyamu sachita dzimbiri mosavuta ngati chitsulo. Ngakhale aluminiyamu imadziwikiratu kudera lachinyontho kwa nthawi yayitali, bola ngati filimu ya aluminium oxide pamwamba pake imakhalabe, aluminiyumu sichichita dzimbiri.
Kodi aluminiyumu adzakhala kunja kwa nthawi yayitali bwanji?
Kodi aluminiyumu ingagwiritsidwe ntchito mpaka liti panja? Moyo wautumiki wa aluminiyumu panja umakhudzidwa ndi zinthu zambiri, monga mikhalidwe ya chilengedwe, zakuthupi khalidwe, kupanga ndi kupanga, ndipo moyo wanthawi zonse wautumiki nthawi zambiri umakhala pakati 10 ndi 20 zaka, Koma nthawi ino imatha kukhala yosiyanasiyana malinga ndi momwe zinthu ziliri.
Zinthu zomwe zimakhudza nthawi yopukutira ya aluminiyamu
Chinyezi ndi kutentha: Aluminium imatha kuchitira ndi mpweya ndi mpweya wamadzi mu malo onyomera, potero ndikuthamangitsa njira yopumira. Nthawi yomweyo, Kutentha kwambiri kumalimbikitsanso maxidation.
Mpweya wabwino: Mvula ya asidi ndi zopindika zamankhwala mlengalenga zimatha kuwononga filimu ya aluminiyamu oxide, Chepetsani mphamvu zake, ndipo imathandizira kuti kukhazikika kwa aluminiyamu.
Chithandizo chapamwamba: Zipangizo za aluminium zomwe zakhala zikuchitika molakwika, electorophis, kupopera mbewu mankhwalawa, ndipo electroflaing imakhala ndi filimu yolimbana ndi oxide, zomwe zimatha kukulitsa moyo wa aluminiyamu.
Zindapusa ndi Zowonongeka: Zowonongeka ndi zowonongeka pamwamba pa aluminiyumu zidzawononga filimu ya aluminium oxide, kupangitsa kuti aluminiyamu ikhale yosavuta kuchita dzimbiri ndi dzimbiri.
Kulumikizana ndi electrolyte: Aluminiyamu, ngati zinthu conductive, sachedwa kukhudzidwa kwa electrochemical mukakumana ndi ma electrolyte, potero kulimbikitsa njira ya dzimbiri.
Zosungirako: Zida za aluminiyamu zomwe zimawonekera kumadera ovuta kwa nthawi yayitali, monga madera a m'mphepete mwa nyanja kapena madera amvula, ichita dzimbiri msanga.
