I-Aluminium Surface Treatment

Ukwelashwa kwe-aluminium ebusweni kuyinqubo esebenzisa inqubo ethile yokuguqula ingaphezulu le-aluminium kanye nezinto zayo zengxubevange, okuhloswe ngayo ukuthuthukisa izindawo zayo ezingaphezulu, ukuthuthukisa ukumelana nokugqwala kanye nobuhle. Ukwelashwa kwe-aluminium ebusweni ikakhulukazi kuhlanganisa i-anodizing, i-electroplating, i-spray coating, ukwelashwa kwamakhemikhali nezinye izindlela zokuhlangabezana nezidingo zokusebenza kwendawo yezinto ze-aluminium emikhakheni ehlukene yezimboni.

Okokuqala, i-anodizing iyindlela evame ukusetshenziswa yokwelashwa kwe-aluminium ebusweni. Ngokufaka i-anodizing impahla ye-aluminium ku-electrolyte ethize, kwakhiwa ifilimu ye-oxide eminyene neyiyunifomu, ethuthukisa ubulukhuni bobuso, ukumelana nokugqoka kanye nokumelana nokugqoka kwezinto ze-aluminium. Ukumelana nokugqwala.

Le filimu ye-oxide inesakhiwo esithile se-pore futhi ifaneleka ukufaka umbala, ukudaya noma ukuvala ukuze uthole imibala ehlukene kanye nemiphumela yokuhlobisa.Le ndlela yokwelapha isetshenziswa kakhulu ezingxenyeni zezimoto, ukwakha izindonga zamakhethini, i-aerospace kanye nezinye izinkambu ukuze kuthuthukiswe izinga eliphezulu kanye nenkonzo. impilo yezinto ze-aluminium.

Okwesibili, i-electroplating ingenye indlela evamile yokwelapha i-aluminium surface, okuhlanganisa i-nickel plating, i-chromium plating, i-zinc plating kanye nezinye izindlela zokwelapha zokufaka insimbi. Ingaphezulu lemikhiqizo ye-aluminium ye-electroplated inokumelana nokugqwala okuhle, ubuhle kanye nezakhiwo zemishini, futhi ifanele ukuhlobisa nokuvikelwa. Inqubo ye-electroplating ingavimbela ngempumelelo ukugqwala kwe-oxidation yezinto ze-aluminium, inwebe impilo yayo yesevisi, futhi ithuthukise ikhwalithi yayo yokubukeka. Isetshenziswa kabanzi ezingxenyeni zezimoto, izinto zasendlini, izinto zokuhlobisa kanye neminye imikhakha.

isifutho enamathela of aluminium materials futhi kuyindlela evamile yokwelapha surface. Ukufafaza i-epoxy resin, i-polyester, upende we-fluorocarbon nezinye izigqoko ngeke zinikeze kuphela ukukhetha kombala ocebile kanye nemiphumela yokuhlobisa, kodwa futhi kuvimbele ngokuphumelelayo izinto ze-aluminium ekuwohlokeni. Ukugqwala kanye ne-oxidation. I-spray coating ifaneleka ekwelapheni okungaphezulu kweminyango namafasitela e-aluminium alloy, amakamelo elanga, amaphaneli okuhlobisa e-aluminium neminye imikhiqizo.

Ngaphezu kwalokho, ukwelashwa ngamakhemikhali kungenye yezindlela ezivamile zokwelashwa kwe-aluminium ebusweni, okuhlanganisa ukukha, ukucwiliswa, ukuhlanza i-solvent nezinye izindlela zamakhemikhali, ezisetshenziselwa ukususa isikali se-oxide nokungcola ebusweni bezinto ze-aluminium ukuze kuhlinzekwe indawo ehlanzekile nefanayo. ngezinqubo zokwelashwa ezilandelayo. Le ndlela yokwelapha ifanele imikhiqizo ye-aluminium enezidingo eziqinile zokuhlanzeka kwendawo ku-electronics, ukuxhumana, ugesi neminye imikhakha.

Ukufingqa, ukwelashwa kwe-aluminium ukuguqula ingaphezulu le-aluminium nezinto zayo ze-alloy ngokusebenzisa uchungechunge lwezinqubo nezindlela zokuthuthukisa izakhiwo zayo ezingaphezulu, ukuthuthukisa ukumelana nokugqwala kanye nobuhle.Izindlela zokwelashwa ezihlukene zendawo zifanele izimboni ezahlukene kanye nezicelo zemikhiqizo. .Inqubo yokwelashwa kwendawo efanele ingakhethwa ngokuvumelana nezidingo ezithile ukuze kutholwe umphumela ongcono kakhulu womsebenzi nokusebenza.
