Aruminiyamu ndeimwe yesimbi dzinoshandiswa zvakanyanya pasi rose, inokosheswa nekuda kwekureruka kwayo, kugara kwenguva refu, uye kushanduka-shanduka. Asi mubvunzo unowanzo bvunzwa ndewekuti: Aruminiyamu inogona kuita ngura here? Mhinduro yacho iri muhunhu hwayo hwemakemikari akasiyana uye kudyidzana kwayo nenharaunda. Muchinyorwa chino, tichaongorora kudzivirira ngura kwearuminiyamu, kuburitsa pachena ngano, uye kupa ruzivo rwakakosha kuti irambe yakasimba.
Kunzwisisa Rust uye Aluminum Oxidation
Ngura imhando chaiyo yengura inokanganisa simbi nesimbi kana ikasangana neokisijeni nemvura. Inoguma neruvara rwe oxide rutsvuku-tsvuku, runopwanya simbi. Zvisinei, aruminiyamu haikanganisi—inooxidation.
Kana aruminiyamu ikasangana neokisijeni, inoumba jira rakatetepa, rinodzivirira rearuminiyamu oxide (Al₂O₃). Kusiyana nengura, jira iri reokisijeni rakakora, harina maburi, uye rakabatana zvakasimba pamusoro pesimbi.Inoshanda sechidziviriro, ichidzivirira kuwedzera kwe oxidation uye ngura. Nzira iyi yekudzivirira yechisikigo inoita kuti aruminiyamu isanyanya kubatwa nengura.
Nei Aluminium Iine Oxidizes Kusiyana neIron
1. Maumbirwo eOxyde Layer:
·Iron oxide (ngura) ine maburi uye inopfava, zvichiita kuti mvura neokisijeni zvipinde zvakadzika musimbi.
· Aluminium oxide yakaoma uye inonamira, ichivhara pamusoro.
2. Kuitazve:
·Aruminiyamu inoshanda zvakanyanya kupfuura simbi asi inoita jira rinodzivirira rinomisa zvimwe zviitiko.
·Simbi haina hunhu uhwu hwekuzviporesa, zvichiita kuti irambe ichiita ngura.
3. Zvinhu Zvinokonzera Kugarika:
·Aruminiyamu inodzivirira ngura munzvimbo dzisina kusimba uye dzine acid asi inogona kusangana nealkali dzakasimba.
Kana Aruminiyamu Ikaora
Kunyange zvazvo aruminiyamu isingakanganiswi nengura, mamwe mamiriro ezvinhu anogona kukanganisa oxide layer yayo:
1. Hunyoro Hwakanyanya:
Kugara kwenguva refu muhunyoro kunogona kukonzera maburi kana kuti hupfu huchena (aluminium oxide).
2. Nzvimbo dzine munyu:
Maion echloride mumvura ine munyu anokurumidza kuoxidation, kunyanya munzvimbo dzegungwa.
3. Kuratidzwa kwemakemikari:
Maacid akasimba (semuenzaniso, hydrochloric acid) kana alkalis (semuenzaniso, sodium hydroxide) anoita zvinoenderana nearuminiyamu.
4. Kukuvara Kwemuviri:
Kukwenya kana kukwenya kunobvisa oxide layer, zvichiita kuti simbi itsva ioxide.
Ngano Dzakajairika Pamusoro Pengura yeAluminium
Ngano 1:Aruminiyamu haimbofi yakaita ngura.
Chokwadi:Aruminiyamu inooresa asi haiori. Kuoresa inyaya yechisikigo, kwete kuora kwechimiro.
Ngano 2:Aruminiyamu haina simba pane simbi.
Ngano 3:Ma alloys anodzivirira oxidation.
Chokwadi: Ma alloys anovandudza hunyanzvi hwakadai sesimba asi haabvisi zvachose oxidation.
Mashandisirwo Echokwadi Ekuramba Kuora kweAluminium Munyika
·Mudenga: Ndege dzinoshandisa aruminiyamu nekuda kwekureruka kwayo uye kudzivirira ngura yemumhepo.
·Kuvaka: Denga realuminium uye siding zvinotsungirira mamiriro ekunze akaoma.
·Mota: Zvikamu zveinjini nemafuremu zvinobatsira kubva mukusagadzikana kwengura.
·Kurongedza: Foil yealuminium nemakani zvinodzivirira chikafu kubva mukuoxidation.
Mibvunzo Inowanzo bvunzwa Nezve Aluminium Rust
Mubvunzo 1: Aruminiyamu inogona kuita ngura mumvura ine munyu here?
A:Ehe, asi inonyorova zvishoma nezvishoma. Kusukurudza nekuputira nguva dzose kunogona kuderedza kukuvara.
Mubvunzo wechipiri: Aruminiyamu inogara kwenguva yakareba sei?
A: Makumi emakore kana ikachengetedzwa zvakanaka, nekuda kwechikamu chayo che oxide chinozviporesa chega.
Mubvunzo wechitatu: Aruminiyamu inoita ngura here mukongiri?
A: Konkriti yealkaline inogona kusangana nearuminiyamu, zvichireva kuti inoda kuputirwa nekudzivirira.
Mhedziso
Aruminiyamu hairi ngura, asi inonyungudika kuti igadzire jira rinodzivirira. Kunzwisisa maitiro ayo uye kutora matanho ekudzivirira kunoita kuti igare kwenguva refu mukushandiswa kwakasiyana-siyana. Ingave inoshandiswa mumaindasitiri kana zvigadzirwa zvemumba, kuramba ngura kwearuminiyamu kunoita kuti ive sarudzo yakavimbika.
