Aluminiyamu ndi imodzi mwazitsulo zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi, zomwe zimayamikiridwa chifukwa chopepuka, kulimba, komanso kusinthasintha. Koma funso lodziwika bwino likupitilirabe: Kodi aluminiyamu ingachite dzimbiri? Yankho lake liri mu mankhwala ake apadera komanso kugwirizana ndi chilengedwe. M'nkhaniyi, tiwona momwe aluminiyamu imakana kudziwira, nthano zongopeka, ndikupereka zidziwitso zotheka kuti zisunge kukhulupirika kwake.
Kumvetsetsa Dzimbiri ndi Aluminium Oxidation
Dzimbiri ndi mtundu wina wa dzimbiri womwe umakhudza chitsulo ndi chitsulo ukakhala ndi mpweya ndi madzi. Zimapangitsa kuti pakhale zofiira zofiira, zowonongeka za oxide zomwe zimafooketsa zitsulo. Aluminium, komabe, sichita dzimbiri - imatulutsa okosijeni.
Aluminiyamu ikakumana ndi okosijeni, imapanga gawo lopyapyala loteteza la aluminium oxide (Al₂O₃). Mosiyana ndi dzimbiri, wosanjikiza wa oxide uyu ndi wandiweyani, wopanda porous, komanso womangika mwamphamvu pamwamba pazitsulo.Zimakhala ngati chotchinga, kuteteza makutidwe ndi okosijeni zina ndi dzimbiri. Chitetezo chachilengedwechi chimapangitsa kuti aluminiyamu isachite dzimbiri.
Chifukwa chiyani Aluminiyamu Imawonjezera Oxidize Mosiyana ndi Iron
1.Mapangidwe a Oxide Layer:
·Iron oxide (dzimbiri) imakhala ndi porous ndi brittle, zomwe zimapangitsa kuti madzi ndi mpweya zilowe mozama muzitsulo.
· Aluminium oxide ndi yaying'ono komanso yomatira, yosindikiza pamwamba.
2.Kuchitanso:
·Aluminiyamu imagwira ntchito kwambiri kuposa chitsulo koma imapanga gawo loteteza lomwe limayimitsa zochitika zina.
·Chitsulo chilibe mphamvu yodzichiritsa yokha imeneyi, zomwe zimachititsa dzimbiri pang'onopang'ono.
3.Zachilengedwe:
·Aluminiyamu imalimbana ndi dzimbiri m'malo osalowerera komanso acidic koma imatha kuchitapo kanthu ndi alkalis amphamvu.
Pamene Aluminium Imawononga
Ngakhale aluminiyamu ndi yosagwira dzimbiri, zinthu zina zimatha kusokoneza wosanjikiza wake wa okusayidi:
1.Chinyezi chachikulu:
Kuwonekera kwa chinyezi kwa nthawi yayitali kungayambitse kupindika kapena phulusa loyera (aluminium oxide).
2.Malo amchere:
Chloride ions m'madzi amchere amathandizira kutulutsa okosijeni, makamaka m'malo am'madzi.
3.Chemical Exposure:
Ma acid amphamvu (mwachitsanzo, hydrochloric acid) kapena ma alkalis (mwachitsanzo, sodium hydroxide) amachita ndi aluminiyamu.
4.Kuwonongeka Kwathupi:
Zing'onoting'ono kapena ma abrasions amachotsa wosanjikiza wa okusayidi, kuwonetsa chitsulo chatsopano ku okosijeni.
Nthano Zodziwika Zokhudza Aluminium Rust
Nthano 1:Aluminiyamu sachita dzimbiri.
Zowona:Aluminiyamu imatulutsa okosijeni koma sichita dzimbiri. Oxidation ndi njira yachilengedwe, osati kuwonongeka kwamapangidwe.
Nthano 2:Aluminiyamu ndi yofooka kuposa chitsulo.
Nthano 3:Aloyi amalepheretsa oxidation.
Zowona: Ma alloys amawongolera zinthu ngati mphamvu koma samachotsa oxidation kwathunthu.
Real-World Applications of Aluminium's Corrosion Resistance
·Zamlengalenga: Matupi a ndege amagwiritsa ntchito aluminiyamu popepuka komanso kukana dzimbiri mumlengalenga.
·Zomangamanga: Zofolerera za aluminiyamu ndi mbali zake zimapirira nyengo yoyipa.
·Zagalimoto: Zigawo za injini ndi mafelemu amapindula ndi kukana dzimbiri.
·Kupaka: Chojambula cha aluminiyamu ndi zitini zimateteza chakudya kuti chisawonongeke.
Mafunso Okhudza Aluminium Rust
Q1: Kodi aluminiyamu ingachite dzimbiri m'madzi amchere?
A:Inde, koma oxidize pang'onopang'ono. Kutsuka ndi zokutira pafupipafupi kumatha kuchepetsa kuwonongeka.
Q2: Kodi aluminiyamu imakhala nthawi yayitali bwanji?
A: Zaka makumi ngati atasamaliridwa bwino, chifukwa cha kusanjika kwake kodzichiritsa.
Q3: Kodi aluminiyamu imachita dzimbiri mu konkire?
A: Konkire yamchere imatha kuchitapo kanthu ndi aluminiyamu, yomwe imafunikira zokutira zoteteza.
Mapeto
Aluminiyamu sichita dzimbiri, koma imadzaza ndi oxidize kuti ikhale yosanjikiza yoteteza. Kumvetsetsa khalidwe lake ndi kutenga njira zodzitetezera kumatsimikizira moyo wake wautali muzogwiritsira ntchito zosiyanasiyana. Kaya zogwiritsidwa ntchito m'mafakitale kapena zapakhomo, kukana kwa aluminium kumapangitsa kukhala chisankho chodalirika.
