Aluminium ndiyo imwe yesimbi dzinoshandiswa zvakanyanya pasi rose, inokosheswa nekureruka kwayo, kusimba, uye kuita zvakasiyana-siyana. Asi mubvunzo wakajairika unoenderera mberi: Aluminium inogona kuita ngura here? Mhinduro iri mumakemikoro ayo akasiyana uye kusangana nemhoteredzo. Muchinyorwa chino, isu tichaongorora aluminium kuramba kwecorrosion, debunk ngano, uye nekupa maitiro ekuona kuti ichengetedze kuvimbika kwayo.
Kunzwisisa Rust uye Aluminium Oxidation
Ngura imhando chaiyo yekuora inobata iron nesimbi kana yasangana neokisijeni nemvura. Zvinokonzera dzvuku-brown, flaky oxide layer inopedza simbi. Aluminium, zvisinei, haina ngura-inoisa oxidize.
Kana aruminiyamu yasangana neokisijeni, inoumba mutete, unodzivirira wealuminium oxide (Al₂O₃). Kusiyana nengura, iyi oxide layer ine dense, isina-porous, uye yakanyatso sungirirwa kune pamusoro pesimbi.Inoshanda sechidziviriro, kudzivirira kuwedzera oxidation uye corrosion. Iyi nzira yekudzivirira yechisikigo inoita kuti aruminiyamu isarambe ichiita ngura.
Nei Aluminium Oxidize Yakasiyana Pane Iron
1.Oxide Layer Structure:
·Iron oxide (ngura) ine porous uye brittle, inobvumira mvura neokisijeni kupinda zvakadzika musimbi.
· Aluminium oxide ine compact uye inonamatira, ichiisa chisimbiso pamusoro.
2.Reactivity:
·Aluminium inonyanya kushandiswa kupfuura iron asi inoumba danda rekudzivirira rinomisa mamwe maitiro.
·Simbi inoshaya chekuzvirapa iyi, zvichiita kuti ngura inofambira mberi.
3.Environmental Factors:
·Aluminium inodzivisa ngura munzvimbo dzisina kwayakarerekera uye dzine acidic asi inogona kuita nemaalkali akasimba.
Apo Aluminium Inoita Corrode
Kunyange zvazvo aluminium isingadziviriri, mamwe mamiriro anogona kukanganisa oxide yayo:
1.Kunyorova kwepamusoro:
Kugara kwenguva refu kune unyoro kunogona kukonzera gomba kana chena poda deposits (aluminium oxide).
2.Nzvimbo inemunyu:
Chloride ions mumvura yemunyu inomhanyisa oxidation, kunyanya munzvimbo dzemugungwa.
3.Chemical Exposure:
Asidhi yakasimba (semuenzaniso, hydrochloric acid) kana alkalis (semuenzaniso, sodium hydroxide) inopindirana nealuminium.
4.Kukuvadza Pamuviri:
Kukwenya kana mabrasions anobvisa iyo oxide layer, ichifumura simbi nyowani kune oxidation.
Zvinozivikanwa Ngano Pamusoro peAluminium Rust
Nhema 1:Aluminium haina ngura.
Chokwadi:Aluminium oxidize asi haina ngura. Oxidation inzira yechisikigo, kwete kuparara kwechimiro.
Nhema dzechipiri:Aluminium haina simba pane simbi.
Nhema dzechitatu:Alloys inodzivirira oxidation.
Chokwadi: Alloys anovandudza zvivakwa senge simba asi haabvise oxidation zvachose.
Real-World Zvishandiso zveAluminium's Corrosion Resistance
·Aerospace: Mitumbi yendege inoshandisa aruminiyamu kune huremu hwayo uye kuramba kuparara kwemuchadenga.
·Kuvaka: Aluminium denga uye siding inomira nemamiriro ekunze akaoma.
·Motokari: Zvikamu zveinjini nemafuremu zvinobatsira kubva mukuramba kuora.
·Packaging: Aluminium foil nemagaba anodzivirira chikafu kubva kune oxidation.
FAQs Nezve Aluminium Rust
Q1: Aluminium inogona kuita ngura mumvura yemunyu here?
A:Hongu, asi iyo oxidizes zvishoma nezvishoma. Kugaro rinsing uye mabhanditi kunogona kuderedza kukuvara.
Q2: Aluminium inogara kwenguva yakareba sei?
A: Makumi emakore kana akachengetwa zvakanaka, nekuda kweiyo yekuzviporesa oxide layer.
Q3: Ko aluminium inopera mukongiri here?
A: Alkaline kongiri inogona kuita nealuminium, inoda machira ekudzivirira.
Mhedziso
Aluminium haina ngura, asi inoisa oxidize kuti iite danda rekudzivirira. Kunzwisisa maitiro ayo uye kutora matanho ekudzivirira kunovimbisa hupenyu hwayo hurefu mumashandisirwo akasiyana. Ingave yekushandiswa kwemaindasitiri kana zvigadzirwa zvemumba, aluminium corrosion resistance inoita kuti ive sarudzo yakavimbika.
