Daim Ntawv Thov ntawm Txhuas Anode Oxidation txheej txheem nyob rau hauv kev lag luam Feem ntau Txheeb

Aluminium thiab nws cov alloys yuav raug oxidized nyob rau hauv huab cua Qhov no yog paub zoo, lub ntuj tsim ntawm txhuas txheej ntawm oxide zaj duab xis yog crystalless, nws yuav ua rau aluminium saum npoo poob thawj cov luster, txawm hais tias no txheej ntawm ntuj oxide zaj duab xis yuav ua rau aluminium saum npoo ib nyuag dhau, tab sis nws yuag heev, txog 4 txog 5 nm, thiab qhov pore loj yog qhov loj, cov neeg kho tshuab kev ua haujlwm kuj tsis zoo, nws tsis tuaj yeem tiv thaiv cov cua ntawm ntau yam xov xwm rau ntxiv xeb ntawm txhuas hlau.

Kev kho cov tshuaj tua kab mob anode tso cai rau cov txhuas thiab nws cov ntawv saum npoo kom tau txais cov tuab zaj duab xis txheej (los ntawm kaum tawm microns rau ntau pua microns) ntau qhov hnyav dua li cov tsoos oxide zaj duab xis. Qhov txheej txheej ntawm cov khoom cua oxidation zaj duab xis tom qab kaw cov kev kho mob, crystalless oxidation zaj duab xis mus rau hauv cov duab zaj duab xis oxide, qhov hws kuj tseem kaw, yog li ntawd cov hlau txheej saum npoo tau ntev ntev tsis hloov, kev ua hauj corrosion, lub tshuab muaj zog tau zoo tuaj, tom qab dyeing tuaj yeem tseem muab kom tau ib qho zoo nkauj tuaj. Vim tias txhuas thiab nws cov khoom siv txhuas muaj ntau yam ntxwv tom qab anode oxidation, aluminium anode oxidation txheej txheem yog dav siv nyob rau hauv kev kho saum npoo ntawm txhuas khoom. Cov ntawv thov hauv kev lag luam tuaj yeem faib tawm raws li hauv qab no.

(1) Txhawm rau tiv thaiv kom tsis txhob xeb ntawm cov khoom: vim qhov anode oxidation los ntawm daim nyias nyias txheej tom qab kev kaw kaw kev kho, muaj qhov zoo nyob ruaj khov rau hauv cov huab cua. Txawm hais tias los ntawm cov tshuaj sulfuric acid, oxalic acid kua lossis chromic acid daws nyob rau hauv cov txheej txheem ib txwm ntawm oxide zaj duab xis, nws qhov kev txhim kho corrosion yog qhov zoo heev, xws li niaj hnub txhuas lauj kaub, lauj kaub, tshuab ntxhua khaub ncaws thiab lwm yam. Lub chromate oxidation txoj kev yog tshwj xeeb tshaj yog rau txhuas welds thiab riveting qhov chaw.

(2) Kev tiv thaiv ib qho kev ua kom zoo nkauj: hauv lub siab pob tshab ntawm oxide zaj duab xis, oxide zaj duab xis muaj cov yam ntxwv ntawm tuaj yeem nqus tau ntau yam organic décor lossis inorganic pigments, oxidation zaj duab xis tuaj yeem tau ntawm ntau yam xim ci thiab qauv, ntxiv rau kev tshwm sim ntawm ntau cov txheej txheem tshiab hauv xyoo tsis ntev los no xws li ib qho oxidation ntau xim, qauv txheej xwm, qauv ntoo, oxide offset luam ntawv hloov luam ntawv, plooj plooj oxidation, kom cov xim zoo nkauj aluminium zoo nkauj dua, zaj duab xis xim no kuj yog xim txheej, xws li cov xim muaj hlau, xws li kub, thiab kub, thiab lwm yam.

(3) Raws li cov txheej txheem hnav nyuaj: hauv sulfuric acid lossis oxalic acid kua tuaj yeem hloov kho los ntawm anode oxidation txheej txheem txheej txheem, tau txais txheej tuab thiab tawv zaj duab xis txheej, siv cov txheej txheej zaj duab xis ntawm qhov thiab nqus kev ua tau zoo los khaws cov roj xaiv, siv tau zoo rau kev sib txhuam ntawm kev ua haujlwm, tib lub sijhawm nrog lubrication thiab hnav-tiv thaiv cov yam ntxwv, xws li lub tsheb thiab lub tsheb laij teb lub tog raj kheej, rab phom thiab lwm yam.

(4) Raws li txheej txheej hluav taws xob tiv thaiv hluav taws xob: aluminium thiab nws cov hlau oxide zaj duab xis txheej muaj cov yam ntxwv ntawm kev tiv thaiv loj, lub thickness ntawm zaj duab xis txheej yog sib npaug rau cov ua hauj, tus yam ntxwv no raws li qhov rwb thaiv tsev ntawm hluav taws xob muaj qee yam tseem ceeb, tuaj yeem ua siv raws li dielectric ntawm capacitors, kuj tuaj yeem siv alumina tawv ua qhov outsourcing ntawm cable, rau nws cov txheej txheej saum npoo av los hloov lub hnab ntawv yas thiab cov chaw kho mob yas nrov dua nyob txawv teb chaws, zaj duab xis tuab yog 27. Thaum 5 m, hnav voltage yog 441V. Yog tias siv cov phenolic resin rau membrane qhov txhaws, nws qhov hnav tsis taus yuav ua kom muaj zog ntau zog los ntawm 2 zaug, hauv kev daws oxalic acid, thaum zaj duab xis tuab nce, koj tuaj yeem tau txais qhov tsis kam 200 s, tawg ntawm qhov hluav taws xob ntawm 980V ntawm cov rwb thaiv tsev zoo, tau kawg, siv cov yam ntxwv no ntxiv rau hauv cov xov hlau, kuj tseem siv tau rau lwm yam cuab yeej hluav taws xob thiab lwm yam.

(5) xim, electroplating rau hauv qab: vim tias oxide zaj duab xis txheej muaj qhov ntxeem tau thiab zoo adsorption muaj peev xwm, nrog cov xim zaj duab xis thiab organic zaj duab xis muaj qhov sib xyaw zoo, tuaj yeem pleev xim rau hauv qab. Zaj duab xis txheej nrog phosphate anode oxidation tuaj yeem siv los ua lub hauv paus ntawm electroplating rau txhuas.

(6) rau kev kos duab niaj hnub: vim yog qhia txog kev ua ntawm aluminium alloy electrolytic coloring txheej txheem, nyob rau hauv xyoo tsis ntev los, domestic electrolytic coloring siv nyob rau hauv kev tsim kho aluminium profile yog nce, nws tsis muaj cov cuab yeej haum tsim nyog ntawm tooj, dub, liab, thiab lwm yam. , nws hnav tsis kam yog qhov zoo dua li ntawm cov pa oxidation, tshwj xeeb tshaj yog tsim nyog ntawm lub hnub tsis kam yog qhov zoo heev, ntau dua 20 xyoo ntawm kev tiv tshav ntuj hauv huab cua tsis muaj xim, uas yog qhov tsis sib luag nrog oxidation coloring txoj kev. Cov xim hluav taws xob pleev xim rau aluminium profiles tuaj yeem tsis tsuas yog siv rau lub tsev qhov rooj thiab lub qhov rais, nrog nws ua cov khw txee, txee thiab lwm yam yog qhov tshwj xeeb.
