Ngaphansi kwezimo ze-electrolyte ezihambisanayo kanye nezinqubo ezithile, i-aluminium kanye nama-alloy ayo akha ifilimu ye-oxide kumkhiqizo we-aluminium (i-anode) ngenxa yesenzo samandla asetshenziswayo. Inhloso ukunqoba amaphutha obulukhuni bomphezulu kanye nokumelana nokuguguleka kwe-aluminium alloy, ukwandisa ububanzi bokusetshenziswa nokwandisa impilo yesevisi.
Iyini i-anode?
Ebhethrini lamakhemikhali, i-electrode ekwazi ukuxova i-electrolyte ibizwa ngokuthi i-anode.
Kunezinhlobo eziningi zezixazululo ezisetshenziswa eku-anodizing. Okwamanje ezisetshenziswa kakhulu yi-sulfuric acid, i-oxalic acid, i-malonic acid, i-sulfonic acid njalo njalo. Okuvame kakhulu kulezi ukusetshenziswa kwe-sulfuric acid njengesixazululo sokwelapha i-oxidative. Izinzuzo ukuthi ifilimu ye-oxide eningi ingatholakala, ubuningi befilimu ye-oxide nayo inkulu, i-filler ingacwiliswa kangcono, kunezinhlobo eziningi kanye nemininingwane yezinto ze-aluminium ezisebenzayo, ubuchwepheshe bokusebenza abuyinkimbinkimbi, futhi ukusetshenziswa kwamandla kuphansi.
Kungani izingxenye ze-aluminium zi-anodized?
1. Ithrekhi yomshini wokumboza.
Ngemva komshini wokugaya we-CNC, kuvame ukuba nemigqa yamathuluzi ebusweni bezingxenye ze-aluminium. Uma amakhasimende efuna ukuthuthukisa "ukubukeka" kwezingxenye ze-aluminium, iningi lawo likhetha ukusebenzisa i-sandblasting + anode yokwelapha ubuso.
2. Thuthukisa ukumelana nokugqwala.
Eqinisweni, i-aluminium alloy iyinsimbi engagqwali ngoba i-aluminium isabela kakhulu futhi ithambekele kakhulu ekuphenduleni kwamakhemikhali nomoya-mpilo emoyeni ukuze yakhe i-aluminium oxide. Ifilimu ye-aluminium oxide ecacile ayibonakali emehlweni omuntu. Le filimu encane ye-aluminium oxide ihlukanisa umoya ukuze i-substrate ye-aluminium ingangcoliswa. Ifilimu ye-oxide eyenzeka ngokwemvelo isebenza njenge-anti-oxidant.
3. Thuthukisa ukumelana nokuguguleka.
I-Aluminium ivame kakhulu ukuklwebheka nokuguguleka, futhi ubulukhuni be-aluminium alloys abunakuqhathaniswa nensimbi phela. Ubuso bephrofayili ye-aluminium yezimboni e-anodized buqinile kakhulu, kanti ubulukhuni befilimu ye-oxide bufinyelela ku-300HV. Ngakho-ke, ayigugi kakhulu futhi akulula ukuyiklwebha.
4. Umbala womphezulu wemikhiqizo ye-aluminium yokuhlobisa.
Ngaphambi kokufakwa kwe-aluminium anodization kanye nokuvalwa, kunezimbobo eziningi eziminyene ebusweni, okulula ukumunca usawoti wensimbi kanye nodayi, futhi ubuso bemikhiqizo ye-aluminium bakha imibala enemibala.
5. Thuthukisa ukuvikela.
I-Aluminium iphatha ugesi kahle kakhulu, kodwa i-aluminium idinga ukufudumala kwezinye izimo. Ifilimu ye-aluminium oxide ene-anodized ayihambisani nogesi.
6. Faka upende phezulu.
Ezinye izindawo ze-aluminium zidinga ukupendwa. Ubuso be-aluminium e-anodized bunamandla okumunca, futhi uqweqwe lufana kakhulu futhi luhle.
Ubukhulu befilimu obujwayelekile be-anodizing ejwayelekile kazwelonke bungama-microns ayi-10-20.
Kungani kudingeka i-anodizing?
Ngakolunye uhlangothi, ngenxa yefilimu ye-oxide engalingani eyakhiwe ngokwemvelo, umbala wobuso be-aluminium alloy uhlukile futhi awubukeki kahle.
Ngakolunye uhlangothi, ifilimu ye-oxide eyakhiwe ngokwemvelo incane, yonakala kalula, futhi ibuthakathaka ekumelaneni nokugqwala. Ifilimu ye-oxide yokwenziwa ekhiqizwa yi-anodic oxidation iyafana, iqinile futhi imelana namafutha okugqwala.
