Ho Senola Nnete: Na Aluminium Rust?
Selelekela
Aluminium e fetohile karolo ea bohlokoa ea bophelo ba rona ba kajeno. Ho tloha likarolong tsa sefofane ho ea ho lijana tsa ho pheha tsa ntlo, ho tloha ho likoloi ho ea ho meaho ea meralo, aluminium e bobebe, makhabane a manganga a entse hore e ratoa haholo har'a baenjiniere, Meetso ea meralo, le bareki ka ho tšoana.
Leha ho le joalo, hara tshebediso e atileng, potso e tloaelehileng e ntse e tsoela pele: E etsa mafome a aluminium?
Ho utloisisa hore na mafome a aluminium ha se boikoetliso feela ba thuto; e ama ka kotloloho tsela eo re khethang lisebelisoa bakeng sa lits'ebetso tse fapaneng, haholo-holo tse pepesehileng ke maemo a leholimo.
Tataiso ena e felletseng e ikemiselitse ho hlakisa potso ena ka ho hlahloba mahlale a aluminium corrosion., ho e bapisa le tshepe (e etsang mafome), le ho sekaseka data ea lefatše la 'nete ho fana ka lintlha tse qaqileng, karabo e tshepehang.
Ka ho khetheha, re tla boela re hlahlobe karolo ea ho etella pele bafepedi ba aluminium, joalo ka Huawei Aluminium, ho fana ka lihlahisoa tsa boleng bo holimo tse tšepahalang le tse tšoarellang. Boitlamo ba bona ba boqapi bo ba etsa sebapali sa bohlokoa 'marakeng oa lefats'e oa aluminium.
Mafome ke Eng? Ho utloisisa Corrosion ka Litšepe
Pele o qoela ka hore na aluminium e rusa, ho bohlokoa ho utloisisa hore na mafome ke eng.
Mokhoa oa ho Rusa ka Tšepe
Mafome ke mofuta o itseng oa kutu o amang tšepe le tšepe. E etsahala ha tšepe e kopana le oksijene le mongobo tikolohong, ho etsa li-oxide tsa tšepe, tse bohlasoa, metsoako e bofubelu bo bosootho. Ts'ebetso ena e senya botsitso ba sebopeho sa tšepe ha nako e ntse e ea.
Lintlha tsa bohlokoa mabapi le mafome a tšepe:
– Karabelo ea lik'hemik'hale:
4Fe + 3O₂ + 6H₂O → 4Fe(OH)₃ (tšepe(III) hydroxide)
- Litšobotsi:
- E boreleli ebile e na le masoba
- E hlaha ka bokgubedu-bosootho
- E etsa hore tšepe e fokotsehe
Hlokomela: Mafome a potlakisa libakeng tse nang le mongobo o phahameng, tlhahiso ea letsoai, kapa ditshila.
Na Aluminium Rust? Pono ea Saense
Sebopeho sa Aluminium
Aluminium e khetholloa e le e bobebe, tšepe e bosoeu bo bosoeu e tsejoang ka tekanyo e babatsehang ea matla-to-boima le ho hanyetsa ho bola. Ho fapana le tšepe, aluminium e bonts'a karabelo e fapaneng haholo ha e pepesetsoa likarolo tsa tikoloho.
Aluminium's Corrosion Resistance
Senotlolo sa ho utloisisa hore na aluminium “mafome” e itšetlehile ka k'hemistri ea eona e ka holimo.
Tšireletso ea Aluminium Oxide Layer
Ha aluminium e pepesehetse moea, ka potlako e hlahisa lera le tšesaane la aluminium oxide (Al₂O₃) hodima bokahodimo ba yona, hangata botenya ba li-nanometers tse seng kae feela. Filimi ena ea oxide e:
- E tsitsitseng
- Adherent
- Ha e khone ho tsoela pele ho kenella ka oksijene
Lera lena la oxide le sebetsa e le mokoallo o sireletsang, ho thibela aluminium e ka tlase ho tsoela pele ho itšoara ka oksijene kapa mongobo. Ka hoo, aluminium ha e ruse ka mokhoa o tloaelehileng.
Aluminium Corrosion vs. Rusting ea tšepe
Le hoja aluminium e sa ruse joaloka tšepe, e ka senyeha tlas'a maemo a itseng, empa tshebetso ena e fapane haholo:
| Tšobotsi | Rusting ea tšepe | Aluminium Corrosion |
|---|---|---|
| Khemistri | Aene e kopana le oksijene e etsang iron oxides | Aluminium e etsa aluminium oxide, e tshireletsang |
| Ponahalo | Ho roala bofubelu bo bofubelu bo bosootho bo bosootho | Hangata e lerootho, tshweu, kapa chelky; ka linako tse ling e mebala haeba tšilafalo e etsahala |
| Phello | Ho fokola ha sebopeho ka nako | Hangata ho itšehla thajana; e ka baka pitting tlasa maemo a itseng |
Na ho ka thoe Aluminium ho “Mafome”?
Hantle-ntle, aluminium e etsa joalo eseng mafome. Ho e-na le hoo, e ea kena Corsuise, e etsang hore ho thehoe lera le sireletsang oxide ho fapana le mafome a mafome.
Ka hona, lentsoe le tloaelehileng “mafome” ha e nepahale ka botekgeniki ha e hlalosa ts'ebetso ea oxidation ea aluminium.
Chemistry ea Aluminium Corrosion
Leha aluminium e hanela mafome, ha e sireletsehe ka ho feletseng ho bola. Lintlha tse fapaneng tsa tikoloho li ka senya lera la eona la oxide e sireletsang, ho lebisa mefuteng e fapaneng ya ho senyeha.
Mefuta ea Aluminium Corrosion

|---|---|---|
| Pitting Corrosion | corrosion ea lehae e theha masoba a manyane | Li-chloride, kgahlamelo ya metsi a letsoai |
| Crevice Corrosion | Khoho sebakeng se koalehileng kapa mapatsong | Mongobo o tsitsitseng, letsoai le phahameng |
| Galvanic Corrosion | Corrosion ha e kopana le motlakase ka dimetale tse sa tshoaneng | Litšepe tse fapaneng li kopane, boteng ba electrolyte |
| Intergranular Corrosion | Corrosion haufi le meeli ea lijo-thollo | Phekolo e sa lokelang ea mocheso, welding |
Lintlha tse Susumetsang ho Corrosion ea Aluminium
- Maemo a Tikoloho: Mongobo, letsoai, tse silafatsang, maemo a pH
- Tšilafalo ea Bokaholimo: Ho ba teng ha chloride, li-sulfate, kapa li-ion tse ling tse mabifi
- Tšenyo ea Mechini: Mekhoro kapa makhopho a sitisang lera la oxide
- Sebopeho sa Alloy: Li-alloys tse ling tsa aluminium li hanyetsana haholoanyane
Mehato ea Thibelo
Ho hanyetsa kutu ea aluminium ho ka ntlafatsoa ka:
- Anodizing (ho tenya lera la oxide)
- Ho sebelisa litlolo kapa lipente tse sireletsang
- Ho sebelisa corrosion inhibitors
- Ho rala meaho ho fokotsa likheo le ho ema ha metsi
Ho bapisa Aluminium le Tšepe: Ke Ntho Efe e Arabang Molemo ho Corrosion?
Ho utloisisa mekhoa ea ho bola ea litšepe tse fapaneng ho lumella khetho e ntle ea thepa. Mona ke kakaretso ea papiso:
| Tšobotsi | Tšepe | Aluminium |

- Etsa moralo ka nepo ho fokotsa likheo le ho kopanya metsi
4. Na aluminium e loketse meaho ea kantle?
Ehlile. Ka lebaka la lera la eona la tlhaho la oxide, aluminium e sebetsa hantle ka ntle, ho etsa hore e be ntle bakeng sa lifensetere, Mona, le thepa ea ka ntle—haholo-holo ha e kopantsoe le liphekolo tse sireletsang.
5. Aluminium e bapisoa joang le tšepe e sa hloekang mabapi le ho bola?
Stainless steel e fana ka khanyetso e ntle ea kutu ka lebaka la litaba tsa eona tsa chromium. Leha ho le joalo, aluminium e bobebe, e baballang chelete e ngata, 'me e hloka tlhokomelo e fokolang libakeng tse ngata.
Litlhahiso Tse Sebetsang Tsa ho Khetha Lintho
- Bakeng sa tikoloho ea leoatle kapa e senyang haholo: Sebelisa li-alloys tsa aluminium tse entsoeng ka anodized kapa tse koahetsoeng tse etselitsoeng maemo a joalo.
- Bakeng sa lisebelisoa tsa sebopeho: Khetha li-alloys tsa aluminium tse matla haholo tse nang le khanyetso e netefalitsoeng ea kutu.
- Bakeng sa merero ea botle: Sebaka sa tlhaho sa aluminium kapa libaka tse nang le anodized li boloka ponahalo ea tsona nako e telele ho feta tšepe.
Kakaretso ea Lintlha Tse Ka Sehloohong
- Aluminium e etsa joalo eseng mafome; e etsa lera le sireletsang oxide.
- Ho bola ha aluminium ho fapane le ho rusa ka tšepe empa ho ntse ho ka etsahala tlasa maemo a itseng.
- Khetho e nepahetseng ea thepa, phekolo ea holimo, 'me tlhokomelo e bohlokoa ho eketsa nako e telele ea aluminium.
- Barekisi ba tsebahalang joalo ka Huawei Aluminium ba fana ka lihlahisoa tse etselitsoeng ho mamella mathata a tikoloho.
Sephetho
Maikutlo a fosahetseng a hore aluminium “mafome” e bakoa ke ho se utloisisane ha mekhoa ea kutu. Ka mahlale, aluminium e hanela mafome ka lebaka la bokhoni ba eona ba ho theha lesela le ipholisang la oxide e le sireletsang ho tsoa ho oxidation e eketsehileng.. Le hoja e ka corrode tlas'a maemo a mabe, kutu ena ha e tshoane le mafome ka chebahalo kapa sebopehong.
Ho khetha lihlahisoa tsa boleng bo holimo tsa aluminium ho tsoa ho barekisi ba tšepahalang ba kang Huawei Aluminium ho ka netefatsa bophelo bo bolelele le ts'ebetso., esita le dibakeng tse thata.
Hore na o ntse o haha moaho, ho etsa koloi, kapa ho etsa lintho tsa lapeng, ho utloisisa boits'oaro ba aluminium ho thusa ho etsa liqeto tse nang le tsebo tse matlafatsang polokeho, durability, le ho boloka litšenyehelo.
Hantle-ntle, aluminium e hlile e etsa joalo eseng mafome - leha ho le joalo, joalo ka lisebelisoa tsohle, e hloka tlhokomelo e nepahetseng le lits'ebetso tse hlokomelang tikoloho hore e atlehe.
Ka ho utloisisa saense le ho sebelisa mekhoa e nepahetseng, o ka sebelisa aluminium ka boitšepo mererong ea hau, ho tseba ho ema ho tiile khahlanong le maikutlo a fosahetseng a mafome.
