Daim ntawv thov teb ntawm Aluminium Anodizing

Nws paub zoo tias aluminium thiab nws cov alloys oxidize hauv huab cua. Lub ntuj tsim oxide zaj duab xis nyob rau saum npoo ntawm txhuas yog amorphous, uas tuaj yeem ua rau cov txhuas hlau nto plam nws qhov qub luster. Txawm hais tias lub ntuj oxide zaj duab xis no tuaj yeem ua rau me ntsis passivate aluminium hlau nto, nws yog nyias, txog 4-5nm, thiab muaj qhov porosity siab thiab tsis zoo txhua yam khoom. Nws tsis tuaj yeem tiv thaiv corrosion ntxiv ntawm txhuas hlau los ntawm ntau yam xov xwm hauv huab cua.
Tom qab kev kho mob anodizing, txheej txheej zaj duab xis ntom ntom (xws li kaum ntawm micrometers mus txog ntau pua micrometers) tuaj yeem tau txais los ntawm txhuas thiab nws cov alloys, uas yog tuab dua li cov oxide zaj duab xis. Cov txheej txheem ntawm oxide zaj duab xis yog txuas ntxiv, thiab cov amorphous oxide zaj duab xis yog hloov mus rau hauv crystalline oxide zaj duab xis. Lub qhov hws tseem raug kaw, kom lub ntsej muag lub ntsej muag ntawm cov hlau tuaj yeem nyob twj ywm tsis hloov mus ntev, thiab kev txhim kho corrosion thiab lub zog txhua yam. Tom qab dyeing, lub ntsej muag zoo nkauj kuj tuaj yeem tau txais. Vim muaj ntau tus yam ntxwv ntawm txhuas thiab nws cov khoom siv hlau tom qab anodizing, cov txheej txheem aluminium anodizing yog dav siv hauv kev kho deg ntawm cov khoom siv txhuas. Cov ntawv thov hauv kev lag luam tuaj yeem kwv yees faib ua pawg hauv qab no.
(1) Kev tiv thaiv ntawm cov khoom siv corrosion: Vim tias qhov kev sib khi tsim nyog ntawm cov yeeb yaj kiab txheej tau los ntawm anodizing, nws muaj kev ruaj ntseg zoo hauv huab cua. Txawm hais tias tau txais los ntawm sulfuric acid tov, oxalic acid tov, los yog cov tshuaj chromic acid hauv cov txheej txheem ib txwm muaj, cov oxide zaj duab xis muaj kev tiv thaiv corrosion zoo heev, xws li txhua hnub txhuas lub lauj kaub, kettles, tshuab ntxhua khaub ncaws, thiab lwm yam. Cov txheej txheem chromic acid oxidation yog tshwj xeeb tshaj yog tsim rau aluminium welded thiab riveted qhov chaw.
(2) Kev tiv thaiv thiab kho kom zoo nkauj: Nyob rau saum npoo ntawm oxide zaj duab xis nrog siab pob tshab, oxide zaj duab xis muaj cov yam ntxwv ntawm adsorbing ntau yam organic lossis inorganic pigments. Ntau yam ci thiab ci xim thiab cov qauv tuaj yeem tau txais ntawm oxide zaj duab xis. Tsis tas li ntawd, nyob rau hauv xyoo tas los no, ntau cov thev naus laus zis tshiab tau tshwm sim, xws li ntau yam xim hauv ib qho oxidation, cov qauv foob pob hluav taws, cov qauv ntoo, oxide offset hloov luam ntawv, porcelain oxidation, thiab lwm yam. qhov muag, Cov yeeb yaj kiab uas muaj xim no yog ob qho tib si zoo nkauj txheej thiab txheej tiv thaiv corrosion, xws li lub teeb. Kub cwj mem thiab handicrafts.
(3) Raws li cov txheej txheem hnav-tiv taus: Hauv cov tshuaj sulfuric acid lossis oxalic acid, cov txheej txheem tuab thiab tawv tuaj yeem tau txais los ntawm kev kho cov txheej txheem ntawm anodizing. Cov pores thiab nqus cov khoom ntawm cov zaj duab xis txheej yog siv los khaws cov roj xaiv, uas yog siv tau zoo rau kev ua haujlwm hauv kev sib txhuam. Nyob rau tib lub sijhawm, nws muaj cov yam ntxwv ntawm lubrication thiab hnav tsis kam, xws li lub tog raj kheej cav, pistons, thiab lwm yam ntawm tsheb thiab tsheb laij teb.
(4) Raws li cov txheej txheem rwb thaiv tsev rau hluav taws xob: Cov oxide zaj duab xis txheej ntawm txhuas thiab nws cov alloys muaj cov yam ntxwv ntawm kev ua haujlwm siab, thiab cov tuab ntawm zaj duab xis txheej yog ncaj qha proportional rau qhov tsis kam. Cov yam ntxwv no muaj qhov tseem ceeb ntawm cov txheej txheem rwb thaiv tsev rau hluav taws xob, thiab tuaj yeem siv los ua dielectric rau capacitors. Aluminium oxide daim tawv nqaij kuj tseem siv tau los ua cov ntaub npog sab nrauv, hloov cov roj hmab thiab cov tawv nqaij yas ua cov txheej rwb thaiv tsev ntawm nws qhov chaw. Nws yog tus neeg nyiam nyob txawv teb chaws, thiab nws qhov kev sib tawg yog 441V thaum cov yeeb yaj kiab tuab yog 27.5um. Yog tias phenolic resin yog siv los ua cov khoom ntim rau daim nyias nyias, nws qhov hluav taws xob tawg tuaj yeem nce ntxiv los ntawm ob zaug. Nyob rau hauv oxalic acid tov, raws li cov zaj duab xis thickness nce, ib tug zoo-zoo rwb thaiv tsev txheej nrog ib tug tsis kam ntawm 200fl thiab ib tug tawg voltage ntawm 980V yuav tau. Tau kawg, qhov no tuaj yeem siv tsis tau tsuas yog rau cov xov hlau, tab sis kuj rau lwm yam khoom siv hluav taws xob thiab lwm yam.
(5) Siv los ua cov txheej hauv qab rau cov tshuaj tsuag pleev xim thiab electroplating: Vim yog qhov ntxeem tau zoo thiab muaj peev xwm adsorption zoo ntawm oxide zaj duab xis txheej, nws muaj adhesion zoo nrog cov xim zaj duab xis thiab cov yeeb yaj kiab organic, thiab tuaj yeem siv los ua cov txheej hauv qab rau tshuaj tsuag pleev xim. Cov zaj duab xis txheej anodized nrog phosphoric acid tuaj yeem ua cov txheej hauv qab rau electroplating ntawm txhuas.
(6) Siv nyob rau hauv niaj hnub architecture: Vim yog kev taw qhia ntawm aluminium alloy electrolytic coloring technology, daim ntawv thov ntawm electrolytic coloring nyob rau hauv lub tsev aluminium profiles tau nce nyob rau hauv xyoo tas los. Nws tsis tsuas yog muaj bronze, dub, liab thiab lwm yam xim uas haum rau lub tsev xim, tab sis kuj muaj kev hnav zoo dua li cov pa oxidation. Nws yog ib qho tsim nyog hais tias nws muaj lub hnub ci zoo heev thiab tsis ploj mus rau hauv qhov chaw tom qab ntau tshaj 20 xyoo ntawm kev raug tshav ntuj thiab hmo ntuj raug, uas yog incomparable rau oxidation coloring txoj kev. Aluminium profiles oxidized los ntawm electrolytic coloring txoj kev yuav tsis tsuas yog siv rau lub tsev qhov rooj thiab qhov rais, tab sis kuj yog tshwj xeeb tshaj yog haum rau siv raws li lub khw txee, txee, thiab lwm yam.
