Dab tsi yog qhov sib txawv ntawm anodizing uas siv raualuminium profiles?

Lub hauv paus ntsiab lus ntawm Anodizing ntawm aluminium profiles yog los ntawm cov tshuaj tiv thaiv electrochemical, tab sis muaj ntau hom anodizing.
Muaj peb txoj hauv kev: oxalic acid, sulfuric acid thiab chromic acid.Cov txheej txheem anodizing no muaj lawv tus kheej yam ntxwv.Hnub noRuiqifeng Cov Khoom Tshiabyuav muab koj cov lus qhia luv luv ntawm ntau hom anodizing siv rau txhuas profiles.
1. Sulfuric acid txoj kev, uas yuav tsum yog cov txheej txheem rau anodic oxidation ntawm aluminium profiles, oxide zaj duab xis tsim los ntawm txoj kev no yog xim tsis muaj xim thiab pob tshab, thiab muaj xim zoo nqus, uas yog tsim rau oxidation xim.Cov electrolyte muaj pes tsawg leeg yog qhov yooj yim thiab ruaj khov, yooj yim rau kev khiav lag luam, thiab qhov tseem ceeb tshaj, tus nqi kuj tsawg.
2. Oxalic acid txoj kev: lub thickness ntawm oxide zaj duab xis ua nyob rau hauv no txoj kev yog kuj siab, thiab nws yuav coj ib co hniav xim.Txawm li cas los xij, txoj kev no yog kim heev thiab yuav tsum muaj hluav taws xob ntau.
3. Chromic acid anodizing zaj duab xis yog nyias dua li sulfuric acid anodizing zaj duab xis, thiab yog tawm dawb los yog grey, uas zoo li cov nyhuv ntawm cov tshuaj txau.Tab sis chromic acid oxidation tsis haum rau xim.Ntxiv mus, hexavalent chromium nyob rau hauv cov tshuaj chromic acid yog tshuaj lom heev, thiab cov nqi kev daws teeb meem thiab cov nqi ua haujlwm yog siab, yog li cov qauv no siv tsawg dua.
4. Kuj tseem muaj txoj kev oxidation tshiab hauv Nyij Pooj - sulfuric acid-oxalic acid oxidation txoj kev, uas absorbs qhov zoo ntawm ob txoj kev thiab dhau los ua oxidation tseem ceeb hauv Nyiv.
