Anodized Aluminium Sheet yog dab tsi?
Anodized aluminium ntawv yog ib qho khoom siv txhuas uas nws nto tau hloov mus rau hauv cov txheej txheem txhuas oxide los ntawm anodic oxidation. Daim ntawv yog immersed nyob rau hauv ib tug acid electrolyte, feem ntau sulfuric acid rau cov hniav thiab tiv thaiv anodizing los yog chromic acid rau tej yam aerospace daim ntaub ntawv, thiab ib tug hluav taws xob tam sim no tau dhau los ntawm lub da dej. Oxygen tso tawm ntawm lub anode ua ke nrog aluminium nto kom loj hlob ib qho nyuaj, ntxeem tau oxide zaj duab xis uas tuaj yeem muab kaw los yog dyed. Cov txheej txheem tshwm sim yog ib qho tseem ceeb nrog lub hauv paus hlau es tsis yog txheej txheej saum toj ntawm nws, uas yog vim li cas anodized finishes tiv taus tev thiab chipping zoo dua li xim.
Zaj duab xis Thickness thiab Hardness
Standard anodic oxide zaj duab xis rau architectural thiab kho kom zoo nkauj kev pab cuam yog feem ntau nyob rau hauv thaj tsam ntawm 5 mus rau 20 microns. Rau kev ua haujlwm hnyav-, nyuaj anodizing hlob cov yeeb yaj kiab ntawm kwv yees li 60 mus rau 200 microns, ua rau saum npoo nrog hardness piv rau cov cuab yeej hardened steel thiab ua kom zoo dua hnav tsis kam. Zaj duab xis thickness yog tswj los ntawm da dej chemistry, kub, tam sim no ceev thiab ua lub sij hawm, thiab nws ncaj qha cuam tshuam kev tiv thaiv corrosion, xim stability thiab puas. Cov neeg yuav khoom qhia cov ntawv anodized yuav tsum tau hais txog qhov yuav tsum tau ua zaj duab xis thickness thiab sealing txoj kev kom lub processor tuaj yeem kho txoj kab raws li.
Dab tsi Alloys tuaj yeem Anodized?
Yuav luag tag nrho cov wrought aluminium alloys tuaj yeem ua anodized, tab sis cov txiaj ntsig sib txawv nrog cov muaj pes tsawg leeg. Nyob rau hauv 5xxx series, 5052 anodizes kom huv si, zoo ib yam tiav thiab yog ib qho kev xaiv nrov rau marine fittings, teeb pom kev zoo thiab cov khoom siv. Nyob rau hauv 6xxx series, 6061 thiab 6082 anodize zoo thiab yog dav siv rau architectural seem thiab structural trim, thaum 6063 yog prized rau nws smooth, uniform anodized tsos nyob rau hauv lub qhov rais thiab qhov rooj profiles. Hauv 7xxx series, 7075 tuaj yeem ua anodized rau hnav tsis kam thiab tiv thaiv corrosion, txawm hais tias nws cov zinc - cov ntsiab lus tooj liab ua kom tiav qhov sib xws xav tau ntau dua li cov alloys purer. Cov magnesium-silicon 6xxx alloys feem ntau muab cov txiaj ntsig zoo tshaj plaws los yog pom tseeb anodized.
Anodic Oxidation vs Chemical Conversion
Nws yog ib qho tseem ceeb kom paub qhov txawv anodic oxidation los ntawm cov tshuaj hloov pauv tshuaj xws li chromate lossis phosphate films. Kev hloov tshuaj lom neeg ua rau cov yeeb yaj kiab nyias nyias, tsuas yog ib feem ntawm micron, uas muaj kev tiv thaiv corrosion tsis tshua muaj thiab ua haujlwm feem ntau yog pretreatment rau painting. Anodic films muaj ntau zaus thicker, muab kev tiv thaiv corrosion zoo dua thiab kev tiv thaiv txhua yam, thiab lees txais dyeing thiab sealing deb ntau ntseeg tau. Vim tias cov tshuaj hloov pauv cov yeeb yaj kiab yog nyias thiab nyuaj rau xim tsis sib xws, cov xim zoo ib yam thiab lub teeb ci ntawm cov khoom txhuas tau ua tiav nrog anodizing es tsis yog nrog kev kho mob hloov dua siab tshiab.
Dimensions thiab Surface Options
Anodized aluminium ntawv yog muaj nyob thoob plaws ntau qhov ntev, feem ntau ntawm 0.1 hli mus txog 200 hli thickness, dav li ntawm 10 mus rau 1250 hli, thiab ntev li ntawm 1000 mus rau 6000 hli, nrog rau qhov ntau thiab tsawg ua rau tus neeg yuav khoom daim duab. Kev kub siab tag nrho tuaj yeem muab tau, suav nrog O, H12, H14, H16, H18, H112, thiab cua sov-kho tempers xws li T3, T351, T5, T6, T651 thiab T7651 nyob ntawm lub hauv paus alloy. Tshaj li anodizing, tib daim ntawv tuaj yeem ci, polished, hairline, txhuam, xuab zeb- blasted, checkered, embossed los yog etched, yog li cov nto tiav yuav tsum tau txhais ua ke nrog cov hlau thiab npau taws ntawm cov lus hais.
Yuav Qhia Li Cas Anodized Aluminium Sheet
Thaum xaj cov ntawv anodized, qhia meej lub hauv paus alloy thiab temper, tuab thiab qhov ntev, hom anodizing (ntshiab, xim lossis tawv), qhov xav tau zaj duab xis thickness, thiab txoj kev sealing. Qhia cov qauv tsim nyog rau ob qho tib si cov khoom siv hauv paus thiab cov txheej anodic, thiab thov cov qauv rau kev pom zoo xim thaum pom qhov teeb meem. Vim tias anodizing siv me me ntawm cov hlau saum npoo, tso cai rau kev hloov pauv me ntsis ntawm qhov tseem ceeb, thiab nco ntsoov tias qhov tsis xws luag hauv daim ntawv nyoos yog pom tom qab anodizing, yog li lub zeb tiav yuav tsum tau pom zoo ua ntej.
FAQ
Puas yog anodized aluminium ntawv corrosion resistant?
Yog lawm. Cov txheej anodic oxide zoo heev txhim kho kev tiv thaiv atmospheric corrosion, av noo thiab tshuaj lom neeg me me piv nrog liab qab txhuas. Sealed anodic films muab kev tiv thaiv zoo tshaj plaws, thiab cov yeeb yaj kiab nyuaj anodized ntxiv qhov tseem ceeb hnav tsis kam. Rau kev pabcuam hauv hiav txwv lossis tshuaj lom neeg hnyav, cov yeeb yaj kiab tuab thiab kev saib xyuas tsis tu ncua raug pom zoo.
Anodized ntawv tuaj yeem tsim tom qab anodizing?
Anodic films yog ib qho nyuaj thiab nkig, yog li khoov lossis tsim tom qab anodizing yuav tawg oxide txheej. Qhov tseeb ua ntu zus yog tsim, tshuab thiab vuam ua ntej, tom qab ntawd anodize qhov tiav. Yog tias daim ntawv tsim yuav tsum pom qhov ua tiav anodized, tag nrho cov seem yog anodized tom qab sib sau.
Dab tsi xim muaj rau anodized aluminium ntawv?
Ntshiab / nyiaj anodizing yog feem ntau, thiab cov zaj duab xis ntxeem tau kuj tuaj yeem dyed nyob rau hauv ntau yam xim xws li dub, bronze, kub, grey thiab xiav. Xim stability nyob ntawm qhov zas xim thiab sealing zoo, nrog rau qib architectural muab qhov zoo tshaj plaws lightfastness rau sab nrauv siv.
Puas yog anodizing hloov qhov ntev ntawm daim ntawv?
Anodizing loj hlob oxide ib feem rau hauv cov hlau nto, ntxiv me me ntawm thickness tag nrho. Rau tus qauv 5-20 micron zaj duab xis qhov hloov pauv qhov loj me, tab sis rau qhov nyuaj anodizing ntawm 60-200 microns nws yuav tsum tau txiav txim siab ntawm qhov chaw nyob ze, thiab cov nyiaj ua haujlwm yuav tsum tau tham nrog cov anodizer.
Vim li cas tib cov txheej txheem anodizing zoo sib txawv ntawm cov hlau sib txawv?
Alloy chemistry hloov cov oxide kev loj hlob thiab nws cov tsos. Purified thiab 6xxx alloys feem ntau muab cov txiaj ntsig zoo, thaum 7xxx thiab qee qhov 2xxx alloys tuaj yeem tshwm tsaus nti lossis streakier. Qhov no yog vim li cas cov qauv xim raug pom zoo: qhov kawg ntxoov ntxoo nyob ntawm qhov tshwj xeeb alloy, temper thiab da dej tej yam kev mob, tsis tsuas yog nyob rau hauv cov xim.
