I-Aluminium ingenye yezinsimbi ezisetshenziswa kakhulu emhlabeni jikelele, ezibaluleke kakhulu ngenxa yokukhanya kwayo okulula, ukuqina kwayo, kanye nokuguquguquka kwayo. Kodwa umbuzo ovamile uyaqhubeka: Ingabe i-aluminium ingagqwala? Impendulo itholakala ezicini zayo zamakhemikhali ezihlukile kanye nokusebenzisana nemvelo. Kulesi sihloko, sizohlola ukumelana nokugqwala kwe-aluminium, sisuse izinganekwane, futhi sinikeze ukuqonda okusebenzayo ukuze silondoloze ubuqotho bayo.
Ukuqonda Ukugqwala kanye ne-Aluminium Oxidation
Ukugqwala uhlobo oluthile lokugqwala okuthinta insimbi nensimbi uma kuvezwa umoya-mpilo namanzi. Kuphumela kungqimba lwe-oxide olubomvu ngokunsundu, oluqhekeka oluyenza buthaka insimbi. Nokho, i-aluminium ayigqwali—iyagqwala.
Uma i-aluminium ihlangana nomoya-mpilo, yakha ungqimba oluncane noluvikelayo lwe-aluminium oxide (Al₂O₃). Ngokungafani nokugqwala, lolu ngqimba lwe-oxide luqinile, alunazo izimbobo, futhi luboshwe ngokuqinile ebusweni bensimbi.Isebenza njengesithiyo, ivimbela ukugqwala okuqhubekayo kanye nokubola. Le ndlela yokuzivikela yemvelo yenza i-aluminium imelane kakhulu nokugqwala.
Kungani i-Aluminium i-Oxidizes ngendlela ehlukile kune-Iron
1. Isakhiwo Sesendlalelo Se-Oxide:
·I-iron oxide (ukugqwala) inezimbobo futhi iyaphuka, okuvumela amanzi nomoya-mpilo ukuthi ungene ujule ensimbini.
· I-aluminium oxide incane futhi inamathela, ivala ubuso.
2. Ukusabela:
·I-aluminium isabela kakhulu kunensimbi kodwa yakha ungqimba oluvikelayo oluvimba ukusabela okuqhubekayo.
·Insimbi ayinalo leli khono lokuziphilisa, okuholela ekugqwaleni okuqhubekayo.
3. Izici Zemvelo:
·I-Aluminiyamu imelana nokugqwala ezindaweni ezingathathi hlangothi nezine-asidi kodwa ingasabela kuma-alkali aqinile.
Lapho i-Aluminium Igqwala
Nakuba i-aluminium imelana nokugqwala, izimo ezithile zingalimaza ungqimba lwayo lwe-oxide:
1. Umswakama Ophakeme:
Ukuchayeka isikhathi eside emswakama kungabangela ukuqhekeka noma ukungcola okumhlophe okufana nempuphu (i-aluminium oxide).
2. Izindawo Ezinosawoti:
Ama-ion e-chloride emanzini anosawoti asheshisa ukubola, ikakhulukazi ezindaweni zasolwandle.
3. Ukuvezwa Kwamakhemikhali:
Ama-asidi aqinile (isib., i-hydrochloric acid) noma ama-alkali (isib., i-sodium hydroxide) asabela ne-aluminium.
4. Umonakalo Ongokwenyama:
Ukuklwebheka noma ukuklwebheka kususa ungqimba lwe-oxide, okuveza insimbi entsha ekungcolisweni.
Izinganekwane Ezivamile Ngokugqwala Kwe-Aluminium
Inganekwane 1:I-aluminiyamu ayilokothi igqwale.
Iqiniso:I-aluminium iyagqwala kodwa ayigqwali. Ukugqwala kuyinqubo yemvelo, hhayi ukuwohloka kwesakhiwo.
Inganekwane 2:I-Aluminiyamu ibuthakathaka kunensimbi.
Inganekwane 3:Ama-alloy avimbela ukubola.
Iqiniso: Ama-alloy athuthukisa izakhiwo ezifana namandla kodwa awaqedi ngokuphelele i-oxidation.
Ukusetshenziswa Kwangempela Kokumelana Nokugqwala Kwe-Aluminium
·Izindiza: Izindiza zisebenzisa i-aluminium ngenxa yokukhanya kwayo kanye nokumelana nokugqwala komoya.
·Ukwakhiwa: Uphahla lwe-aluminium kanye nodonga kumelana nesimo sezulu esibi.
·Izimoto: Izingxenye zenjini kanye nohlaka ziyazuza ekumelaneni nokugqwala.
·Ukupakisha: I-aluminium foil kanye namathini kuvikela ukudla ekungcolisweni yi-oxidation.
Imibuzo Evame Ukubuzwa Mayelana Nokugqwala Kwe-Aluminium
Umbuzo 1: Ingabe i-aluminium ingagqwala emanzini anosawoti?
A:Yebo, kodwa i-oxidize kancane kancane. Ukuhlanza njalo kanye nokugqoka kunganciphisa umonakalo.
Umbuzo 2: I-aluminium ihlala isikhathi esingakanani?
A: Iminyaka eminingi uma inakekelwa kahle, ngenxa yongqimba lwayo lwe-oxide oluziphilisayo.
Umbuzo 3: Ingabe i-aluminium iyagqwala kukhonkolo?
A: Ikhonkrithi ye-alkaline ingase ihlangane ne-aluminium, okudinga ukumbozwa okuvikelekile.
Isiphetho
I-Aluminium ayigqwali, kodwa iyagqwala ukuze yakhe ungqimba oluvikelayo. Ukuqonda ukuziphatha kwayo nokuthatha izinyathelo zokuvimbela kuqinisekisa ukuthi ihlala isikhathi eside ezinhlotsheni ezahlukene zokusebenza. Kungakhathaliseki ukuthi isetshenziswa ezimbonini noma emikhiqizweni yasekhaya, ukumelana nokugqwala kwe-aluminium kuyenza ibe ukukhetha okuthembekile.
