Nyob rau hauv cov electrolyte thiab cov txheej txheem tshwj xeeb, txhuas thiab nws cov alloys tsim ib zaj duab xis oxide rau ntawm cov khoom txhuas (anode) vim yog qhov kev ua ntawm cov tam sim no siv. Lub hom phiaj yog kom kov yeej qhov tsis zoo ntawm qhov nyuaj ntawm qhov chaw thiab kev hnav tsis kam ntawm txhuas alloy, nthuav dav qhov kev siv thiab ua kom lub neej ua haujlwm ntev.
Ib qho anode yog dab tsi?
Hauv lub roj teeb tshuaj lom neeg, lub electrode uas tuaj yeem oxidize cov electrolyte hu ua anode.
Muaj ntau hom tshuaj siv rau hauv anodizing. Tam sim no feem ntau siv yog sulfuric acid, oxalic acid, malonic acid, sulfonic acid thiab lwm yam. Feem ntau ntawm cov no yog siv sulfuric acid ua cov tshuaj kho oxidative. Qhov zoo yog tias tuaj yeem tau txais cov zaj duab xis oxide ntom ntom, cov zaj duab xis oxide kuj loj, cov khoom sau tuaj yeem ntub zoo dua, muaj ntau hom thiab cov lus qhia ntawm cov khoom siv txhuas siv tau, cov txheej txheem ua haujlwm tsis nyuaj, thiab kev siv hluav taws xob tsawg.
Vim li cas cov khoom siv txhuas thiaj li anodized?
1. Npog txoj kev ua haujlwm.
Tom qab CNC machining, feem ntau muaj cov kab cuab yeej ntawm qhov chaw ntawm cov khoom txhuas. Yog tias cov neeg siv khoom xav txhim kho "qhov zoo li" ntawm cov khoom txhuas, feem ntau ntawm lawv xaiv siv sandblasting + anode rau kev kho qhov chaw.
2. Txhim kho kev tiv thaiv xeb.
Qhov tseeb, txhuas alloy yog ib hom hlau uas tsis yooj yim xeb vim tias txhuas muaj zog heev thiab nws yooj yim ua rau muaj kev sib xyaw tshuaj nrog cov pa oxygen hauv huab cua los ua txhuas oxide. Cov zaj duab xis txhuas oxide pob tshab tsis pom rau tib neeg lub qhov muag. Cov zaj duab xis txhuas oxide nyias no tsuas yog cais cov huab cua kom cov txhuas substrate tsis raug oxidized. Cov zaj duab xis oxide uas tshwm sim ntuj ua haujlwm ua cov tshuaj tiv thaiv oxidant.
3. Txhim kho kev hnav tsis kam.
Aluminium yog qhov tshwj xeeb tshaj yog rau kev khawb thiab hnav, thiab qhov nyuaj ntawm cov hlau alloys tsis tuaj yeem piv rau hlau tom qab tag nrho. Qhov chaw ntawm anodized industrial aluminium profile yog qhov nyuaj heev, thiab qhov nyuaj ntawm oxide zaj duab xis ncav cuag 300HV. Yog li ntawd, nws yog hnav-resistant heev thiab tsis yooj yim rau khawb.
4. Xim ntawm cov khoom siv txhuas kho kom zoo nkauj.
Ua ntej txhuas anodization thiab sealing, muaj ntau lub qhov hws ntom ntom ntawm qhov chaw, uas yooj yim nqus cov ntsev hlau thiab cov xim zas, thiab qhov chaw ntawm cov khoom txhuas tsim cov xim muaj yeeb yuj.
5. Txhim kho kev rwb thaiv tsev.
Cov txhuas ua hluav taws xob tau zoo heev, tab sis qee zaum cov txhuas xav tau kev rwb thaiv tsev. Cov yeeb yaj kiab anodized txhuas oxide tsis ua hluav taws xob.
6. Pleev xim rau saum.
Qee qhov chaw txhuas yuav tsum tau pleev xim. Qhov saum npoo ntawm cov txhuas anodized muaj zog nqus, thiab cov txheej txheej zoo nkauj dua thiab zoo nkauj dua.
Lub thickness ntawm zaj duab xis dav dav ntawm lub teb chaws tus qauv anodizing yog 10-20 microns.
Vim li cas thiaj li yuav tsum tau anodizing?
Ntawm ib sab tes, vim yog cov zaj duab xis oxide tsis sib xws tsim los ntawm ntuj, xim ntawm cov hlau txhuas sib txawv thiab tsis zoo nkauj.
Ntawm qhov tod tes, cov zaj duab xis oxide uas tsim los ntawm ntuj tsim yog nyias, yooj yim puas tsuaj, thiab tsis muaj zog tiv taus corrosion. Cov zaj duab xis oxide cuav uas tsim los ntawm anodic oxidation yog sib xws, ntom thiab tiv taus cov roj corrosion.
