Qhov sib txawv ntawm cov khoom siv anodized thiab non-anodized aluminium, yog dab tsi cov kev pab cuam ntawm alloy aluminium anodized?
Aluminium anosided: Cov txheej txheem tiv thaiv khoom siv uas muaj cov ntaub ntawv hlau ua ib zaj duab xis oxide rau ntawm qhov chaw uas siv cov tshuaj anodic tam sim no hauv cov kua electrolyte. Tsis tas li ntawd hu ua qhov anodic oxidation. Tom qab cov khoom siv hlau los yog cov khoom siv anodized rau ntawm qhov chaw, lawv qhov kev ua kom tsis muaj zog, kev hnyav, hnav ua haujlwm, kev tiv thaiv, kev kub cev, thiab lwm yam zoo heev. Cov khoom siv hlau anodized yog txhuas. Cov tshuaj txhuam hniav aluminium yog feem ntau ua tau rau cov kua qaub electrolyte nrog txhuas raws li qhov anode. Hauv cov txheej txheem electrolysis, cov pa oxygen react nrog txhuas los ua cov pa oxide. Zaj yeeb yaj kiab yog tsis txaus txaus thaum pib ntawm lub tsim. Txawm hais tias muaj ib qho tsis kam, tsis zoo oxygen ions nyob rau hauv lub electrolyte tseem tuaj yeem ncav cuag qhov txhuas qhov tsim kom muaj oxide zaj duab xis. Raws li cov zaj duab xis thickness tsub kom, qhov tsis kam kuj yuav tsub kom, thiab tam sim no cov kua roj electrolytic me dua. Nyob rau lub sij hawm no, cov zaj duab xis txheej sab nrauv nyob hauv kev sib txuas nrog lub tshuab ntshawb tshuaj yog sib txuas. Thaum tus nqi oxide tsim rau ntawm qhov txhuas nti maj equilibrates nrog tus nqi ntawm cov tshuaj dissolution, no oxide zaj duab xis yuav ua tau ntau dua thickness nyob rau hauv cov khoom siv tes taws los ntawm electrolytic. Cov duab ntawm aluminium anodized muaj txheej txaj txheej, uas yooj yim adsorbs dyes thiab cov ntaub qhwv xim, li dyeing thiab kev txhim kho nws cov khoom zoo nkauj. Tom qab oxide cov yeeb yaj kiab tau ntxiv los kho dej kub, cov dej kub kub los yog kua ntsev ntsev, nws tuaj yeem txhim kho nws txoj kev txhim kho thiab ua haujlwm hnyav.
