Anodized aluminium yog cov txheej txheem electrolytic oxidation nyob rau hauv qhov chaw ntawm txhuas thiab txhuas alloys feem ntau yog xa mus rau hauv oxide zaj duab xis, uas muaj kev tiv thaiv, kho kom zoo nkauj, thiab lwm yam khoom siv. Raws li cov ntsiab lus no, anodization ntawm txhuas tsuas yog suav nrog cov txheej txheem ntawm kev tsim cov yeeb yaj kiab anodized.
Cov hlau los yog cov hlau alloy yog siv los ua anodes los tsim cov oxide zaj duab xis rau saum npoo los ntawm electrolysis. Hlau oxide zaj duab xis hloov lub xeev nto thiab cov khoom, xws li nto xim, txhim kho corrosion kuj, txhim khu kev hnav tsis kam thiab hardness, tiv thaiv cov hlau nto, thiab lwm yam. Piv txwv li, nyob rau hauv aluminium anodic oxidation, aluminium thiab nws cov alloy yog muab tso rau hauv cov khoom siv electrolyte. (xws li sulfuric acid, chromic acid, oxalic acid, thiab lwm yam) raws li lub anode, nyob rau hauv qhov kev txiav txim ntawm tej yam kev mob thiab thov tam sim no, electrolysis. Lub anodic aluminium los yog nws cov alloy oxidizes, tsim ib txheej nyias ntawm alumina rau ntawm qhov chaw, nws thickness yog 5 ~ 30 microns, thiab cov anodic zaj duab xis nyuaj tuaj yeem ncav cuag 25 ~ 150 microns. Anodized aluminium los yog nws cov alloy, txhim kho nws cov tawv tawv thiab hnav tsis kam, mus txog 250 ~ 500 kg / square mm, zoo kub tsis kam, nyuaj anodized zaj duab xis melting point mus txog 2320K, zoo heev rwb thaiv tsev, tawg voltage mus txog 2000V, thiab txhim khu corrosion kuj. Nws tsis corrode hauv ω=0.03NaCl ntsev tsuag rau ntau txhiab teev. Cov oxide zaj duab xis muaj ntau cov micropores hauv txheej nyias, tuaj yeem nqus tau ntau yam lubricants, tsim nyog rau kev tsim lub tog raj kheej lossis lwm yam hnav-tiv taus; Membrane microporous adsorption muaj peev xwm tuaj yeem pleev xim rau hauv ntau yam xim zoo nkauj. Cov hlau tsis-ferrous lossis lawv cov alloys (xws li txhuas, magnesium thiab lawv cov alloys, thiab lwm yam) tuaj yeem ua anodized. Txoj kev no yog siv dav hauv cov khoom siv tshuab, dav hlau thiab tsheb qhov chaw, cov cuab yeej precision thiab cov khoom siv hauv xov tooj cua, khoom siv txhua hnub thiab kho kom zoo nkauj hauv tsev, thiab lwm yam.
Lub teb chaws tus qauv feem ntau siv cov tshuaj tshuaj tshuaj ib txwm siv los tshuaj xyuas cov qib ntawm alumina. Cov txheej txheem yog tedious raws li lub voj voog tsom xam thiab nruj raws li GB/T15000. Tom qab cov qauv kev npaj, sib tov, tus nqi ruaj khov, kev ntsuam xyuas tsis sib xws, kev faib khoom ib txwm muaj, kev txheeb xyuas kev ruaj ntseg, kev tshuaj xyuas kev tsim khoom, thiab siv cov kev ntsuam xyuas thiab lwm cov txheej txheem nyuaj, thiab tom qab ntawd los ntawm kev soj ntsuam kev sib koom ua ke ntawm pawg neeg txheeb xyuas, cov qauv tsim qauv tsim nyog, hauv kab nrog YZ/T272-1998 "Alumina" cov khoom siv tshuaj lom neeg muaj pes tsawg leeg, tuaj yeem suav tias yog cov khoom tsim nyog hauv tebchaws.
Tsim los ntawm 1993, Guangdong Zhonglian Aluminium yog ib qho kev lag luam txhuas profile loj uas npog thaj tsam ntawm 100, 000 square metres nrog ntau tshaj 800 tus neeg ua haujlwm uas tshwj xeeb hauv kev tsim, tsim, thiab tsim khoom, tshwj xeeb tshaj yog muaj txiaj ntsig tshwj xeeb hauv anodizing. , qhov zoo ntawm cov khoom tau mus txog thoob ntiaj teb ua theem.
Yam khoom | Technology tus nqi |
Thickness ntawm zaj duab xis | AA10, AA15, AA20, AA25 |
Lub qhov sealing | Tsawg dua lossis sib npaug li 30mg / d ㎡ |
Corrosion kuj | Ntau dua lossis sib npaug li 9 qib |
Hnav tsis kam | Ntau dua lossis sib npaug li 300g / um |
Nta Ntawm Zhonglian Anodized Aluminium Profile:
1) oxide zaj duab xis thickness tshaj 13mu
2) Siv oxidized xuab zeb No. 100
3) Finely sanded yam tsis muaj txhua yam kab
4) Tsis yooj yim rau khawb, tsis muaj grit
5) Super hnav tsis kam, huab cua tsis kam, corrosion kuj
Guangdong Zhonglian Aluminium GB Matt Anodized Dub, yog cov muag khoom sab saum toj ntawm peb cov khoom kub muag hauv Guangdong Zhonglian Aluminium, uas koj tuaj yeem nrhiav tsis tau cov kab tshuab ntawm qhov chaw (zoo dua li lwm cov chaw tsim khoom) nrog kev ua haujlwm zoo nkauj zoo nkauj sandblasting. Qhov saum npoo tsis tuaj yeem raug khawb nrog anodizing thickness ntawm 10 thiab 13 um. Cov cim kos me me tuaj yeem raug tshem tawm yooj yim. Txawm li cas los xij, lwm cov khoom lag luam nrog cov xim tib yam hauv kev ua lag luam yuav yooj yim bruised vim lub thickness me me, thiab nws tseem nyuaj rau tshem tawm cov cim kos ntawm lawv qhov chaw.
