Aluminium ndomumwe wesimbi anoshandiswa zvakanyanya, anokosheswa nemheremhero yayo, kusimba, uye kusanganisa. Asi mubvunzo unozivikanwa unopfuurira: unogona aluminium ngura? Mhinduro iri mune yayo yakasarudzika yemakemikari zvivakwa uye kudyidzana nenzvimbo. Munyaya ino, isu tichazotarisa kuonga's Corrosion kupokana, ngano dzakashata, uye ipa ruzivo rwekuita kuti tirambe takaperera.
Kunzwisisa Rust uye Aluminium Oxidation
Ngura inzira chaiyo yekukanganisa inokanganisa simbi uye simbi painoratidzwa neokisijeni nemvura. Izvo zvinoguma nekudzvanywa-tsvuku, flky oxide layer inopera simba simbi. Aluminium, zvisinei, hainguti-iyo oxidize.
Kana aluminium ichisvika mukubatana neokisijeni, inoumba yakatetepa, inodzivirira denderedzwa realuminium oxide (Al₂o₃). Kusiyana nerutoko, nziyo idzi nzombe dzakasimba, dzisiri dzisina-simba, uye dzakasungirirwa kusunganidzwa kusimba kwesimbi.Inoita sechisungo, ichidzivirira zvimwe oxidation uye corrosion. Izvi zvekudzivirira zvechisikigo zvinoita kuti aluminium inodzivirira zvakanyanya nekukanda.
Nei aluminium oxiddaally zvakasiyana kupfuura simbi
1.Oxide layer chimiro:
·Simbi oxide (ngura) iri poroumba uye brittle, kubvumira mvura uye oksijeni kupinza zvakadzika kuita simbi.
· Aluminium oxide inokoshesa uye kuisana, kusimbisa pasi.
2.reactivity:
·Aluminium inonyanya kuita kupfuura simbi asi inoumba denderedzwa rinodzikisira rinowedzera kumwezve maitiro.
·Simbi inoshaya iyi yekuzvishingisa pfuma, inotungamira kuenderera mberi nekucheka.
3.ENVERMENTAL zvinhu:
·Aluminium inoramba kuora mune isina kwavakarerekera nharaunda uye inogona kuita neakasimba alkalis.
Apo Aluminium inoita corrode
Nepo aluminium iri kuora-kupokana, mamwe mamiriro anogona kukanganisa nzombe yayo ox:
1.Hwechi humidity:
Kufumurwa kwenguva refu kune unyoro kunogona kukonzera kupamba kana kuchena poda deposits (Aluminium oxide).
2.Salty nharaunda:
Chloride ions mumvura munyu inosimudzira oxidation, kunyanya mumarongero emarungu.
3.chemical kuratidzwa:
Zvakasimba zvakanaka (semuenzaniso, hydrochloric acid) kana alkalis (semuenzaniso, sodium hydroxide) ita nealuminium.
4.PHYSICAIC kukuvara:
Kukanda kana kubvarura bvisa iyo nzombe ivhu, kufumura nyowani nyowani kune oxidation.
Ngano dzakajairika pamusoro pealuminium ngura
Nhema 1:Aluminium haambofi ngura.
Chokwadi:Aluminium oxidizes asi haina ngura. Oxidation chiitiko chechisikigo, kwete kushomeka kwechimiro.
Nhema 2:Aluminium haina simba pane simbi.
Nhema 3:Alloys anodzivirira oxidation.
Chokwadi: Alloys kugadzirisa zvivakwa senge simba asi usabvisa oxidation zvachose.
Real-World Accualy yeAluminium's Corrostion Resistance
·Aerospace: miviri ndege inoshandisa aluminium yeyakajeka uye kuramba kuPompherc Corrosion.
·Kuvaka: Aluminium Roofing uye Kutsigira Kunotsikisa mamiriro ekunze.
·Zvemotokari: Mifananidzo yemijini nemapuranga kubatsirwa kubva kune corrosion kuramba.
·Packaging: Aluminium foil uye macens kuchengetedza chikafu kubva oxidation.
FAQs nezve aluminium ngura
Q1: Inogona aluminium ngura mumvura munyu?
A:Ehe, asi iyo inodaira zvishoma nezvishoma. Kugara uchichinjika uye kuungana kunogona kuderedza kukuvara.
Q2: Nguva yakareba sei aluminium yekupedzisira?
A: Makumi emakore kana kuchengetwa zvakanaka, nekuda kwekuzvishingisa kwehukuru hwehukuru.
Q3: Aluminium ngura mukongiri?
A: Alkaline kongiri inogona kuita nealuminium, inoda machira anodzivirira.
Mhedziso
Aluminium haina ngura, asi iyo oxidaizi yekuumba denderedzwa rekudzivirira. Kunzwisisa maitiro ayo uye kutora matanho ekudzivirira anofunga kuti hupenyu hwayo hunokosha mumanyorero akasiyana siyana. Kunyangwe kushandiswa kwemaindasitiri kana zvigadzirwa zveimba, kurwisa kweAluminium's Corrosion kunoita kuti ive sarudzo yakavimbika.
