1. Anodizing
I-Anodizing yindlela esetyenziswa ngokubanzi yonyango lomphezulu kwi-alloys ye-aluminium ebandakanya ukudala i-porous oxide layer kumphezulu wesinyithi.Inkqubo ibandakanya i-anodizing (i-electrolytic oxidation) ye-aluminium kwisisombululo se-asidi.Ubunzima be-oxide layer bunokulawulwa, kwaye uluhlu olubangelwayo lunzima kakhulu kunentsimbi engaphantsi.Le nkqubo ingasetyenziselwa ukongeza umbala kwi-alloys ye-aluminium ngokusebenzisa iidayi ezahlukeneyo.I-Anodizing ibonelela ngokuphucuka kokumelana nomhlwa, ukuxhathisa okukhulu kokunxiba, kunye nokuphuculwa kokuxhathisa kwe-abrasion.Ukongeza, inokonyusa ubulukhuni kwaye inokuphucula ukuncamathela kweengubo.
2. I-Chromate Conversion Coating
I-Chromate Conversion Coating yindlela yonyango yomphezulu apho i-chromate yokuguqula i-coating isetyenziswe kumphezulu we-alloy ye-aluminium.Inkqubo ibandakanya ukuntywiliselwa iinxalenye ze-aluminiyam ye-alloy kwisisombululo se-chromic acid okanye i-dichromate, eyenza umaleko omncinci we-chromate yokuguqulwa kwengubo kumphezulu wesinyithi.Umaleko udla ngokuba tyheli okanye uhlaza, kwaye ubonelela ngokhuseleko lwe-corrosion oluphuculweyo, ukwanda kokunamathela kwipeyinti, kunye nesiseko esingcono sokubambelela kwezinye iingubo.
3. Ukuchola (Ukuqhotsa)
I-Pickling (etching) yinkqubo yonyango yomphezulu wekhemikhali ebandakanya ukuntywiliselwa i-alloys ye-aluminiyam kwisisombululo se-asidi ukususa ukungcola komphezulu kunye nokudala ukuthungwa komphezulu orhabaxa.Inkqubo ibandakanya ukusetyenziswa kwesisombululo se-acidic kakhulu, njenge-hydrochloric okanye i-sulfuric acid, ukususa i-surface layer yesinyithi.Le nkqubo inokususa nayiphi na intsalela okanye i-oxide layers kwi-aluminium alloy surface, iphucule ukufana kwendawo, kwaye ibonelele nge-substrate engcono yokunamathela kwi-coating.Nangona kunjalo, ayiphuculi ukuxhathisa kwe-corrosion, kwaye umphezulu unokuba sengozini ngakumbi kwi-corrosion kunye nezinye iindlela zomonakalo ukuba awukhuselwanga ngokwaneleyo.
4. I-Plasma Electrolytic Oxidation (PEO)
I-Plasma Electrolytic Oxidation (PEO) bubuchwephesha bonyango obuphezulu obubonelela ngobungqingqwa, obuqinileyo, kunye nomaleko oshinyeneyo weoksidi kumphezulu wealloyi zealuminiyam.Inkqubo ibandakanya ukucwiliswa kweengxenye ze-aluminium i-alloy kwi-electrolyte, kwaye emva koko isebenzise umbane okhoyo kwizinto eziphathekayo, ezibangela ukuba kwenzeke i-oxidation reaction.Isiphumo somaleko we-oxide sibonelela ngokugqwesileyo kokunganyangekiyo, ukuxhathisa ukubola, kunye nokwanda kobunzima.
5. I-Powder Coating
Ukugquma umgubo yindlela ethandwayo yonyango lomphezulu we-alloys ye-aluminium ebandakanya ukongeza umaleko okhuselayo womgubo kumphezulu wesinyithi.Inkqubo ibandakanya ukutshiza umxube wee-pigments kunye ne-binder phezu kwentsimbi, ukudala ifilimu edibeneyo ephiliswa kumaqondo aphezulu.Idyasi yomgubo ephumayo ibonelela ngokuqina, ukumelana nokukrweleka, kunye nokumelana nokugqwala.Ifumaneka ngemibala eyahlukeneyo, ukuthungwa, kunye nokugqitywa, oko kuyenza ibe sisisombululo esifanelekileyo kwizicelo ezininzi.
Ukuqukumbela
Ukuqukumbela, iindlela zonyango zomphezulu ezikhankanywe ngasentla ziyimizekelo embalwa yeendlela ezininzi ezisetyenziselwa ukunyanga i-alloys ye-aluminium.Ngalunye kolu nyango luneenzuzo zalo ezizodwa, kwaye iimfuno zesicelo sakho ziya kugqiba ukuba loluphi unyango olulungele iprojekthi yakho.Nangona kunjalo, kungakhathaliseki ukuba luhlobo luni lonyango olusetyenzisiweyo, into ebaluleke kakhulu kukuqinisekisa ingqwalasela efanelekileyo ekulungiseleleni umphezulu kunye nokucoca iziphumo ezilungileyo.Ngokukhetha indlela efanelekileyo yonyango yomphezulu, unokuphucula inkangeleko, ukuqina, kunye nokusebenza kwamalungu akho e-aluminium alloy, okukhokelela kwiimveliso ezikumgangatho ophezulu ezihlala ixesha elide.
