Hauv cov ntawv thov kev lag luam feem ntau, txhawm rau tiv thaiv txhuas thiab lwm yam khoom siv los ntawm xeb thiab khawb, thiab ua kom cov khoom zoo nkauj dua, lawv cov chaw feem ntau raug kho nrog dub anodizing lossis electroless nickel plating. Yog li dab tsi yog dub anodizing?
Anodizing yog dab tsi?
Nyob rau hauv chemistry, txhuas yog ib tug reactive hlau uas nkag reacts nrog oxygen los tsim ib tug ntom oxide zaj duab xis. Cov zaj duab xis tsim los tiv thaiv no tiv thaiv cov txhuas los ntawm xeb, tab sis vim tias cov yeeb yaj kiab no nyias nyias, yuav tsum tau kho qhov chaw tiv thaiv ntxiv -anodizing-.
Anodizing yog txheej txheem kho saum npoo uas suav nrog electrolyzing cov hlau uas tsis yog -ferrous hlau, xws li txhuas, magnesium, lossis titanium, hauv cov kua qaub electrolyte los tsim cov yeeb yaj kiab oxide ntom ntom ntawm cov khoom siv. Cov yeeb yaj kiab no tiv taus corrosion, txhim kho hnav tsis kam, thiab ua haujlwm rau lub hom phiaj zoo nkauj.
Anodized films feem ntau yog pob tshab thiab muaj qhov ntxeem tau microstructure nrog pore qhov ntau thiab tsawg ntawm 100 Å txog 300 Å (1 Å=0.1} nm). Tus naj npawb ntawm cov micropores no loj heev, qhov nruab nrab ntawm 50-700 billion pores ib cubic centimeter.

Dab tsi yog dub anodizing?
Peb tuaj yeem nkag siab dub anodizing li anodizing ntxiv rau dub dyeing. Ua ntej blackening, tus txheej txheem anodizing yuav tsum tau ua, ua raws li cov txheej txheem electrolytic dyeing kom xim cov pores ntawm oxide zaj duab xis.
Dub anodizing ua haujlwm li cas?
Anodizing:Nyob rau hauv ib tug acidic electrolyte da dej, txhuas yog siv los ua anode rau anodizing. Oxygen molecules reacts chemically nrog cov txhuas nto, tsim cov alumina deposit.
Dyeing:Tom qab anodizing, aluminium nto yuav ntxeem tau thiab ntom; cov pores no pab khaws cov xim siv rau hauv cov txheej txheem dub anodizing.
- Electrolytic Dyeing: Cov txheej txheem no suav nrog kev tso dej ntawm cov txhuas anodized hauv lwm da dej electrolytic. Lub da dej no muaj cov ntsev hlau hnyav thiab cov electrodes ua los ntawm cov hlau tsis muaj steel; cov ntsev hlau tuaj yeem suav nrog kev sib xyaw ntawm tin, nickel, thiab cobalt. Nyob rau hauv lub da dej tshiab no, cov anodized txhuas ua raws li cathode. Thaum pib ntawm electrolysis, ntsev yog tso rau hauv qhov pores ntawm anodized txhuas.
- Inorganic Dyeing: Inorganic dyes yog dej-insoluble, thiab cov inorganic ntsev siv nyob rau hauv cov txheej txheem no muaj cobalt sulfide. Cov khoom kho nrog inorganic dyes rau dub anodizing tsis tshua muaj fading.
- Organic Dyeing: Organic dyes yog dej -soluble. Thaum siv cov organic dyes, lawv yuav tsum xub yaj hauv dej sov ua ntej muab ntxiv rau hauv da dej dyeing. Tom ntej no, cov anodized txhuas qhov chaw yog raus rau hauv ib da dej dyeing, tso cai rau cov organic dye nkag mus rau semi- ntxeem tau txheej ntawm qhov chaw. Qhov tsaus nti xim xim, lub sijhawm ntev ntawm cov organic dyeing yog xav tau.
Sealing:Cov xim dub yog tsau hauv qhov pores. Qhov no yog ua nyob rau hauv ib tug nickel acetate los yog acid da dej, uas yuav pab tau harden lub txheej, tiv thaiv cov xim los ntshav thiab fading.
Qhov zoo thiab qhov tsis zoo ntawm dub anodizing
| Qeb | Cov yam ntxwv tseem ceeb |
| Qhov zoo | Kev ua tau zoo, muaj zog corrosion kuj, nqi -zoo, kub- ruaj khov, thiab xim ceev ceev |
| Qhov tsis zoo | Cov kev xav tau ua haujlwm siab, nquag tawg, thiab cov khoom siv tsawg |
