Ngemuva kokuthi ingaphezulu lephrofayili ye-aluminium i-anodised, kuzokwakhiwa ifilimu evikelayo ukuvimba umoya, ukuze iphrofayili ye-aluminium ngeke ifakwe oxidized. Lokhu kungenye yezizathu zokuthi kungani amakhasimende amaningi akhetha ukusebenzisa amaphrofayili we-aluminium, ngoba asikho isidingo sokupenda kanye nezindleko zokulungisa ziphansi. Kepha kwesinye isikhathi ingaphezulu kwephrofayili ye-aluminium mnyama. Yini isizathu salokhu? Ake ngikunikeze isingeniso esinemininingwane.
Kungaba nezizathu eziningi zokwenza okumnyama kwezindawo ze-aluminium alloy, ezinye zazo:
1. I-Oxidation: I-Aluminium ivezwa umoya futhi ihlangana ngo-oxygen ukwakha ungqimba lwe-aluminium oxide ebusweni. Le nhlangano ye-oxide imvamisa icacile futhi ivikela i-aluminium kusuka kokunye ukugqwala. Kodwa-ke, uma isendlalelo se-oxide siphazamiseka noma silimele, siveza i-aluminium eyisisekelo emoyeni futhi singadala ezinye i-oxidation, okuholele ekubukekeni okuthambile noma okumnyama.
2. Ukusabela Kwamakhemikhali: Ukuchayeka kumakhemikhali athile noma izinto kungadala ukuguquguquka noma ukucwaswa kwe-aluminium alloy ebusweni. Isibonelo, ukuvezwa kuma-acid, izixazululo ze-alkaline, noma usawoti kungadala ukusabela kwamakhemikhali okungadala ukuba mnyama.
3. Ukwelashwa kokushisa: Ama-Alluminium Alloys avame ukwenziwa ngaphansi kwezinqubo zokwelashwa okushisa ukuze andise amandla abo nobulukhuni bayo. Kodwa-ke, uma izinga lokushisa noma isikhathi sokwelashwa kokushisa selingalawulwa kahle, lizodala ukuguquguquka noma ukuqina kobuso.
I-4. Ukungcola: Ukuba khona kokungcola ebusweni be-Aluminium Alloys, njengamafutha, amafutha noma okunye ukungcola, kuzodala ukuguquguquka noma ukuwela ngenxa yokusebenzisana komhlaba noma ukusebenzisana komhlaba.
I-5. Ukufaka i-anodizing: Ukufaka i-anodizing inqubo yokwelashwa engaphezulu ehilela ukwelashwa kwe-electrochemical kwe-aluminium ukwakha ungqimba lwe-oxide ebusweni. Le nhlangano ye-oxide ingadaywa noma ifakwe ukukhiqizwa ukukhiqiza okuhlukahlukene, kufaka phakathi okumnyama. Kodwa-ke, uma inqubo yokungenisa i-anodizing ingalawulwa kahle noma amadayi noma ama-color noma amabala ampofu, kungaholela ekuqedeni okungalingani noma ukuguquguquka.
