I-Aluminiyam yenye yezona zinyithi zisetyenziswe kakhulu kwihlabathi jikelele, ezixabisekileyo ngenxa yokukhanya kwayo, ukuqina, kunye nokuqalisa. Kodwa umbuzo oqhelekileyo uyaqhubeka: Ngaba i-aluminium rust? Impendulo ilele kwiipropathi zayo ezahlukileyo kunye nokusebenzisana nendalo. Kweli nqaku, siza kuhlolisisa ukunganyangeki kwe-aluminium, iintsomi ezigwenxa, kwaye zinike ukuqonda okusemandleni ukugcina ukuthembeka.
Ukuqonda i-rump kunye ne-aluminium oxidation
I-rust yindlela ethile ye-corosion echaphazela i-iron kunye nentsimbi xa ityhilwe kwioksijini namanzi. Ikhokelela kwi-reddish-brown, i-flakiy oxide oxide ibuthathaka intsimbi. I-Aluminiyam, nangona kunjalo, ayisebenzi-i-oxidad.
Xa i-aluminium iza kudibana neoksijini, i-theate emncinci, ikhusela ialuminium oxide (Alūo₃). Ngokungafaniyo ne-runust, lo mbambo oxinayo uxinekile, ongenzi mbi, kwaye uqinile kumphezulu wentsimbi.Isebenza njengomqobo, ukuthintela i-oxidation enye kunye nokusula. Le ndlela yokhuselo yendalo yenza i-aluminium ixhathise kakhulu.
Kutheni i-Aluminium ayinyanzelekanga ngakumbi kunentsimbi
I-1.oxide yesakhiwo:
·I-Iron Oxide (i-rust) i-porous kwaye ibrile, ivumela amanzi neoksijini ukuze ingene nzulu kwintsimbi.
· I-Aluminium Oxide iqulathiweyo kwaye inamathelelwe, kutyhala umphezulu.
2.Ukusebenza:
·I-Aluminiyam isebenza ngakumbi kune-iron kodwa yenziwa ngumaleko okhuselayo othintela ezinye iindlela.
·I-iron ayinazo le ndawo yokuziqhelanisa, ekhokelela ekuqhubeni phambili.
Imiba ye-3.Deencving
·I-Aluminium ixhathise ukuvela kwiindawo ezingathathi cala kunye ne-acidic kodwa zinokuphendula nge-alkalis eyomeleleyo.
Xa i-aluminium iyabonga
Ngelixa ialuminiyam yindawo yokunganyangeki, iimeko ezithile zinokuphawula ungqimba lwayo:
I-1.High theids:
Ukuboniswa ixesha elide kumswakama kunokubangela i-pipotits okanye iidipozithi zepowdery ezimhlophe (ialuminium oxide).
I-2.salty Iindawo:
I-chloride i-ions kwi-ityuwa yetyuwa ekhawulezayo, ngakumbi kwizicwangciso zaselwandle.
3.Umtsalane:
I-AIDS eyomeleleyo (umzekelo, i-hydrochloric acid) okanye i-alkalis (umzekelo, i-sodium hydroxide) iphendule nge-aluminium.
Umonakalo we-4physical:
I-scratchect okanye i-abrasoons isusa ungqimba lwe-Oxide, ukuveza intsimbi entsha kwi-oxidation.
Iintsomi eziqhelekileyo malunga ne-aluminium rust
Intsomi 1:I-aluminium ayikaze ibe rusts.
Inyaniso:I-Aluminium Axidime kodwa ayiphumi. I-oxidation yinkqubo yendalo, hayi ukonakaliswa kwesakhiwo.
Intsomi 2:I-aluminium ibuthathaka kunensimbi.
Intsomi 3:I-AFALS TUPONSOS.
Inyaniso: I-alloys iphucule iipropathi ezifana namandla kodwa ungayiphelisi i-oxidation ngokupheleleyo.
Izicelo zokwenyani zeHlabathi zeAluminiyam yeAluminium
·I-Aerospace: Amanqanaba enqwelo moya asebenzisa ialuminiyam ye-aluminiightweight anesh kunye nokuchasana ne-themospic symospion.
·Ulwakhiwo: Uphahla lwe-aluminium kunye ne-dainti yokunyuka kwemozulu.
·I-AutoMotive: Icandelo le-injini kunye neefreyimu zixhamla ekuchanyoneni kokungakhathali.
·Ukupakisha: I-Aluminium Foil kunye ne-cans kukhusela ukutya kwi-oxidation.
I-FAQs malunga ne-aluminium rust
I-Q1: Ngaba i-aluminium rust ngamanzi etyuwa?
A:Ewe, kodwa iyacotha kancinci. Ukuqhekeka rhoqo kunye neengubo zinokunciphisa ukonakala.
I-Q2: I-Aluminium ihlala ixesha elingakanani?
A: Ishumi leminyaka ukuba igcinwe ngokufanelekileyo, ngenxa yongqimba lwayo lwe-Oxide.
I-Q3: Ngaba i-aluminium rust kwikhonkrithi?
A: Ikhonkrithi ye-Alkaline inokuphendula nge-aluminium, ifuna impahla yokukhusela.
Ukuqukumbela
I-Aluminiyam ayihambelani, kodwa iyawa-oxidid ukwenza umaleko wokukhusela. Ukuqonda indlela yokuziphatha kwayo kunye nokuthatha amanyathelo okuthintela kuqinisekisa ubumnene kwizicelo ezahlukeneyo. Nokuba ngaba ufuna ukusebenzisa imizi mveliso okanye iimveliso zasekhaya, ukunganyangeki kwe-aluminium kwenza ukhetho oluthembekileyo.
