Ngemuva kokuthi ubuso bephrofayili ye-aluminium bufakwe i-anodized, kuzokwakhiwa ifilimu evikelayo ukuze ivimbele umoya, ukuze iphrofayili ye-aluminium ingabi ne-oxidized.Lesi futhi esinye sezizathu ezenza amakhasimende amaningi akhethe ukusebenzisa amaphrofayili e-aluminium, ngoba asikho isidingo sokupenda futhi izindleko zokulondoloza ziphansi.Kodwa ngezinye izikhathi ubuso bephrofayili ye-aluminium buba mnyama.Siyini isizathu salokhu?Ake ngikunike isingeniso esiningiliziwe.
Kungaba nezizathu eziningi zokuthi mnyama indawo ye-aluminium alloy, ezinye zazo yilezi:
1. I-Oxidation: I-Aluminium ichayeka emoyeni futhi ihlangana nomoya-mpilo ukuze yakhe ungqimba lwe-aluminium oxide ngaphezulu.Lolu ngqimba lwe-oxide luvamise ukuba sobala futhi luvikela i-aluminium ekugqwaleni okwengeziwe.Kodwa-ke, uma ungqimba lwe-oxide luphazamisekile noma lonakalisiwe, ludalula i-aluminium engaphansi emoyeni futhi lungabangela ukukhishwa kwe-oxidation okwengeziwe, okuholela ekubukekeni okufiphele noma okumnyama.
2. Ukusabela kwamakhemikhali: Ukuchayeka kumakhemikhali athile noma izinto kungabangela ukushintsha kombala noma kube mnyama kwendawo ye-aluminium alloy.Isibonelo, ukuchayeka kuma-acids, izixazululo ze-alkaline, noma usawoti kungabangela ukusabela kwamakhemikhali okungabangela ubumnyama.
3. Ukwelashwa kokushisa: Ama-alloys e-aluminium ngokuvamile angaphansi kwezinqubo zokushisa ukushisa ukuze kwandiswe amandla abo nobulukhuni.Kodwa-ke, uma izinga lokushisa noma isikhathi sokwelashwa kokushisa kungalawulwa kahle, kuzodala ukuguquguquka noma ukumnyama kwendawo.
4. Ukungcola: Ukuba khona kwezinto ezingcolisayo ebusweni bengxubevange ye-aluminium, njengamafutha, amafutha noma okunye ukungcola, kuzodala ukushintsha kombala noma kube mnyama ngenxa yokusabela kwamakhemikhali noma ukusebenzisana kwendawo.
5. I-Anodizing: I-anodizing inqubo yokwelapha engaphezulu ebandakanya ukwelashwa kwe-electrochemical ye-aluminium ukuze kwakhe ungqimba lwe-oxide phezulu.Lesi sendlalelo se-oxide singadaywa noma sifakwe umbala ukuze kukhiqizwe okuhlukahlukene, okuhlanganisa nokumnyama.Kodwa-ke, uma inqubo ye-anodizing ingalawulwa kahle noma odayi noma ama-colorants awekhwalithi ephansi, ingaholela ekuqedeni okungalingani noma ekushintsheni kombala.
