1. I-Anodizing
I-Anodizing iyindlela yokwelapha engaphezulu esetshenziswa kakhulu yama-alloys e-aluminium ehlanganisa ukudala ungqimba lwe-oxide olunezimbotshana ebusweni bensimbi.Inqubo ihlanganisa i-anodizing (i-electrolytic oxidation) ye-aluminium esixazululweni se-asidi.Ubukhulu bongqimba lwe-oxide bungalawulwa, futhi ungqimba oluvelayo lunzima kakhulu kunensimbi engaphansi.Le nqubo ingasetshenziswa futhi ukwengeza umbala kuma-alloys e-aluminium ngokusebenzisa odayi abahlukahlukene.I-Anodizing inikeza ukumelana nokugqwala okuthuthukisiwe, ukumelana nokuguga okukhulu, nokumelana nokuhuzuka okuthuthukisiwe.Ukwengeza, kungandisa futhi ubulukhuni futhi kungathuthukisa ukunamathela kwezingubo.
2. I-Chromate Conversion Coating
I-Chromate Conversion Coating iyindlela yokwelapha engaphezulu lapho kusetshenziswa khona ukuguqulwa kwe-chromate ebusweni bengxubevange ye-aluminium.Inqubo ihilela ukucwiliswa kwezingxenye ze-aluminium ingxubevange esixazululweni se-chromic acid noma i-dichromate, edala ungqimba oluncane lwe-chromate yokuguqulwa kwe-chromate ebusweni bensimbi.Ungqimba ngokuvamile luphuzi noma luluhlaza, futhi luhlinzeka ngokuvikeleka kokugqwala okuthuthukisiwe, ukunamathela okwenyukayo kupende, kanye nesisekelo esingcono sokunamathela kwezinye izimbotshana.
3. Ukuchoma (Ukuchoma)
I-Pickling (etching) inqubo yokwelapha indawo yamakhemikhali ehlanganisa ukucwiliswa kwengxubevange ye-aluminium esixazululweni se-asidi ukuze kukhishwe ukungcola okungaphezulu nokudala ukuthungwa kwendawo engaphezulu.Inqubo ihilela ukusetshenziswa kwesisombululo esine-acidic kakhulu, njenge-hydrochloric noma i-sulfuric acid, ukususa ungqimba olungaphezulu lwensimbi.Le nqubo ingasusa noma yiziphi izingqimba noma izingqimba ze-oxide endaweni ye-aluminium alloy, ithuthukise ukufana kwendawo, futhi inikeze i-substrate engcono yokunamathela kokunamathela.Kodwa-ke, ayithuthukisi ukumelana nokugqwala, futhi indawo engaphezulu ingaba sengcupheni yokugqwala nezinye izinhlobo zomonakalo uma ingavikelwe ngokwanele.
4. I-Plasma Electrolytic Oxidation (PEO)
I-Plasma Electrolytic Oxidation (PEO) iwubuchwepheshe bokwelapha obusezingeni eliphezulu obunikeza ungqimba lwe-oxide oluwugqinsi, oluqinile, noluminyene phezu kwama-alloys e-aluminium.Inqubo ihilela ukucwiliswa kwezingxenye ze-aluminium alloy ku-electrolyte, bese usebenzisa amandla kagesi entweni, okubangela ukusabela kwe-oxidation.Isendlalelo se-oxide esiwumphumela sinikeza ukumelana okuhle kakhulu kokugqoka, ukumelana nokugqwala, nokuqina okwandayo.
5. I-Powder Coating
Ukugcoba ngempushana kuyindlela yokwelapha engaphezulu ethandwayo yama-alloys e-aluminium ehlanganisa ukwengeza ungqimba oluvikelayo lwempushana ebusweni bensimbi.Le nqubo ihilela ukufafaza ingxube ye-pigments kanye ne-binder ebusweni bensimbi, ukudala ifilimu ehlangene ephulukiswa emazingeni okushisa aphezulu.Ijazi lempushana eliwumphumela linikeza isiphetho esihlala isikhathi eside, esingaklwebheki, futhi esimelana nokugqwala.Itholakala ngemibala ehlukahlukene, ukwakheka, kanye nokuqedwa, okuyenza ibe yisixazululo esifanelekile sezinhlelo zokusebenza eziningi.
Isiphetho
Sengiphetha, amasu okwelapha angaphezulu okukhulunywe ngawo ngenhla ayizibonelo ezimbalwa zamasu amaningi asetshenziselwa ukwelapha ama-alloys e-aluminium.Ngayinye yalezi zindlela zokwelapha inezinzuzo zayo ezihlukile, futhi izidingo zohlelo lwakho lokusebenza zizonquma ukuthi yikuphi ukwelashwa okulungele iphrojekthi yakho.Kodwa-ke, kungakhathaliseki ukuthi iyiphi indlela yokwelapha esetshenzisiwe, into ebaluleke kakhulu ukuqinisekisa ukunakekelwa okufanele ekulungiseni kwendawo nokuhlanza ukuze uthole imiphumela emihle.Ngokukhetha indlela yokwelapha engaphezulu efanele, ungathuthukisa ukubukeka, ukuqina, nokusebenza kwezingxenye zakho ze-aluminium alloy, okuholela emikhiqizweni yekhwalithi ephezulu ehlala isikhathi eside.
