Anodized aluminium qhov chaw nrog ntau yam xim

Vim lawv lub teeb yuag thiab siab zog,aluminium thiab nws ntau qib ntawm alloysfeem ntau siv cov khoom siv hauv tsev hauv ntau yam lag luam, suav nrog kev kho mob, tsheb, thiab aerospace.Nws tsis muaj teeb meem twg kev tsim khoom siv los ua cov khoom no.Nto xovNws yog ib qho tseem ceeb los txhim kho cov khoom no ' mechanical properties and aesthetic beauty.

Vim tias qhov dav ntawm cov xim tuaj yeem coated ntawm qhov chaw los ntawmanodizing, nws yog qhov nrov tshaj plaws nto xov txoj kev siv nyob rau hauv lub ntiaj teb no manufacturing.Aluminium qhov chaw yog tsim los ua kom ruaj khov thiab zoo heev resisters rau hnyav ib puag ncig raug, ua tsaug rau cov xim anodizing.Tsis tas li ntawd, muaj peev xwm tiv taus abrasion tuaj yeem ua tiav los ntawm cov xim anodizing.Kab lus no yuav nthuav davcov txheej txheem Aluminium anodizing, ntau yam xim, kev sib txuam xim, thiab lwm yam txheej txheem.

Aluminium Anodizing txheej txheem

Kev tu cov khoom tsim yog thawj kauj ruam hauv anodizing aluminium, thiab on-engraving alkaline yog tus neeg saib xyuas zoo tshaj plaws rau txoj haujlwm.Tag nrho cov roj teeb thiab lwm yam khoom uas yuav cuam tshuam cov txheej txheem anodizing raug tshem tawm thaum lub sijhawm ntxuav.Alkaline etching yuav tsum tau ua tom qab ntxuav kom tshem tawm cov oxides uas tseem tshuav ntawm qhov chaw.Qhov kev xaiv zoo tshaj plaws rau nws yog sodium hydroxides.

Cov kauj ruam tom ntej yog tshem tawm Cov Ntxuav thiab etched txhuas qhov chaw rau hauv cov tshuaj nitric acid kom lub ntsej muag du thiab npaj rau anodizing.

Ntau theem rau aluminium anodized xim

Thaum kawg, Aluminium Cheebtsam yog dipped nyob rau hauv ib tug electrolyte ntawm sulfuric acid rau anodizing.Lub Cathode nyob sab nraum lub tank electrolyte.Aluminium Cheebtsam uas yuav tsum tau coated ua tus anode.Tom qab ntawd cov hluav taws xob tam sim no raug siv rau lub electrode ("+" davhlau ya nyob twg rau lub anode thiab "-" davhlau ya nyob twg rau Cathode).Tam sim no, cov hluav taws xob tam sim no txav los ntawm cov tshuaj electrolytic thiab tso tawm cov oxide ions, uas mus rau aluminium substrate los tsim cov txheej txheem oxide nyob rau saum npoo.

Xim ntawm Aluminium Anodized Parts

Feem ntau, Anodized aluminium qhov chaw yog xim siv plaub txoj hauv qab no: kev cuam tshuam xim, xim xim, electro coloring, thiab ib qho xim xim.Cia peb saib ze dua ntawm lawv txhua tus tam sim no.

Cov xim hluav taws xob

Ntau yam xim yog yooj yim achievable nyob rau hauv anodized txhuas qhov chaw nto nrog lubelectrolytic xim.Electrolytic coloring siv cov ntsev sib txawv raws li tus neeg saib xyuas cov xim, qhov twg cov hlau ions ntawm cov ntsev siv tau tso rau hauv qhov pores ntawm anodized txhuas qhov chaw.Yog li ntawd, cov xim nyob ntawm cov hlau siv hauv cov tshuaj ntsev.

Electro coloring txheej txheem

Raws li ib feem ntawm cov txheej txheem electrolysis, anodized nto yog submerged nyob rau hauv concentrated daws ntawm hlau ntsev kom txog thaum txaus pigment yog precipitated los tsim cov xim uas xav tau.Yog li, cov xim nyob ntawm cov hlau siv hauv cov ntsev, thiab kev siv cov xim yog nyob ntawm lub sijhawm kho (30 vib nas this mus rau 20 feeb).

Qee cov hlau ntsev thiab cov xim siv hauv cov xim anodized txhuas 

Xim xim

Lwm txoj hauv kev rau xim cov xim anodized aluminium yog xim xim.Cov txheej txheem no tsuas yog dipping cov khoom kom muaj xim rau hauv lub tank uas muaj cov tshuaj zas xim.Qhov kev siv ntawm cov xim nyob rau hauv txoj kev no yog nyob ntawm qhov sib txawv ntawm qhov sib txawv xws li cov xim xim, lub sijhawm kho, thiab qhov kub thiab txias.

Specifications rau dyeing xim:

Cov lus qhia kom zoo meej dye coloring

·        Kev ntxuav cov txhuas anodized yog qhov tseem ceeb vim tias cov kua qaub nyob rau ntawm qhov chaw tuaj yeem cuam tshuam rau txoj kev tuag.Hauv qee qhov xwm txheej, muaj cov kua qaub tiv thaiv aluminium los ntawm dyeing.Yog li, ua ntej pib da dej, siv sodium bicarbonate los desorb.

·        Cov kauj ruam ntawm anodizing thiab dye da dej yuav tsum ua kom tiav ib txhij, nrog rau cov khoom raug muab tso rau hauv lub tank dyed sai li sai tau thaum lawv raug tshem tawm ntawm lub tank anodizing.

·        Tsis tas li ntawd, khaws cov kua qaub los yog lwm yam paug tawm ntawm lub tank dye.

Integral xim

Integral coloring txheej txheem muab ob txoj kev sib txawv.Ua ntej, cov khoom siv txhuas yog anodized, thiab cov khoom siv anodized yog xim nrog cov alloys.Yog li ntawd, kev ua haujlwm ntawm ib qho tshwj xeeb alloy hauv cov txheej txheem no yog tsim cov xim li cas.Raws li qhov muaj pes tsawg leeg ntawm cov khoom siv txhuas thiab cov kev ua haujlwm, cov xim muaj peev xwm muaj xws li los ntawm cov bronze golden los ntawm kev sib sib zog nqus bronze mus rau dub.

Kev cuam tshuam xim

Txoj hauv kev no suav nrog kev nthuav dav ntawm pore qauv thiab tso tawm ntawm cov hlau tsim nyog raws li cov xim xav tau ntawm qhov chaw kom tau cov xim xim.Zoo li koj yuav tau txais xim xiav-grey yog tias koj tso nyiaj npib tsib xee.Hauv paus, kev cuam tshuam xim yog tsim thaum lub teeb tawm tsam anodized aluminium nto thiab yog refracted, reflected, los yog absorbed.

Sealing-txheej txheem

Txheej txheem sealing

Lub hom phiaj tseem ceeb ntawm cov txheej txheem sealing yog kom tsis txhob plam cov molecules ntawm absorbing rau hauv lub qhov hws.Vim tias cov roj nplua nyeem lossis lwm cov molecules tsis txaus siab yog qee zaum khaws cia rau hauv qhov hws, nws thiaj li ua rau muaj qhov xeb.Qee cov khoom siv sib khi yog npib tsib xee acetate, potassium dichromate, thiab dej kub npau npau.

1.          Txoj kev dej kub

Stainless hlau los yog lwm yam khoom siv inert feem ntau yog siv los ua lub tank sealing.Cov xim txhuas xim yog thawj zaug hauv dej kub (200 0F), qhov twg aluminium monohydrate daim ntawv nyob rau saum npoo, nrog rau qhov sib npaug ntawm qhov ntim.Yog li ntawd, undesirable molecules raug tshem tawm ntawm lub pore.

2.           Txoj kev Nickel Fluoride

Cov txheej txheem no softens anodized aluminium Cheebtsam.Nyob rau hauv txoj kev no, fluoride nickel yog nkag mus rau anodized txhuas.Fluoride ion tam sim no mus rau hauv lub qhov hws, qhov twg cov nickel ion precipitates rau ntawm qhov chaw thiab tsim nickel hydroxide los ntawm kev sib txuas nrog dej molecules, thaum kawg thaiv cov pores.

3.          Potassium Dichromate txoj kev

Cov txheej txheem no siv cov tshuaj poov tshuaj dichromate (5% w / V) los kaw cov khoom txhuas anodized.Ua ntej, cov khoom yog immersed rau li 15 feeb nyob rau hauv lub tank uas muaj ib tug boiling tov ntawm poov tshuaj dichromate.Tom ntej no, qhov chaw ntawm qhov chaw absorbs chromate ions, thiab txheej tshwm sim thaum cov ions ua hydrated.Txawm hais tias tsis tshua muaj stain-resistant dua li lwm txoj kev sealant, cov txheej txheem no tseem muaj txoj hauv kev yooj yim rau kev sib khi.

Xim sib phim

Cov xim sib txawv tuaj yeem sib txawv raws li ntau yam batch;Txawm li cas los xij, Yog tias koj ua raws li cov txheej txheem tseeb ntawm cov xim rau cov khoom siv txhuas anodized.Vim li no, cov txheej txheem thiab lwm cov ntsiab lus zoo li qib ntawm txhuas siv, hom kev ua tiav, qhov concentration ntawm cov tuag, thiab cov qauv crystalline ntawm qhov saum npoo yuav tsum yog ze li ntawm cov khoom sib xws kom tau txais cov xim sib xws.

Xaus

Tom qab tshuaj xyuas cov anodizing thiab xim ntawm txhuas qhov chaw, nws yog qhov tseeb tias qhov txiaj ntsig zoo tshaj plaws ntawm aluminium anodizing yog lub peev xwm los cog cov xim sib txawv ntawm qhov chaw, uas tsis yog tsuas yog txhim kho cov khoom siv thiab kev zoo nkauj tab sis kuj ua tau raws li kev xav tau ntawm kev lag luam.Tsis tas li ntawd, txoj kev xim electro-xim yog qhov zoo tshaj plaws ntawm plaub txoj hauv kev rau xim vim nws tso cov xim electrochemically thiab tso cai rau tsim ntau yam xim los ntawm kev xaiv cov ntsev kom zoo.

Undoubtedly, cov txheej txheem aluminium anodizing yog qhov nyuaj heev vim nws koom nrog ntau yam chemistry, khoom siv science, thiab engineering manufacturing.Txawm li cas los xij, yuav tsis muaj qhov tsis meej pem yog tias koj xaiv pebkev pabcuam anodizing. Peb cov khoom siv science thiab mechanical engineeringcov kws tshaj lij yuav muab rau koj nrog aluminium anodizing ntawm lub siab tshaj plaws caliber, thiab koj tuaj yeem xaiv cov xim uas haum rau koj qhov project.
