Ⅰ-B: Koj Xim Anodized Aluminium Li Cas?
Muaj plaub txoj hauv kev rau xim anodized txhuas:
1. Dye: Cov ntu tshiab anodized yog immersed nyob rau hauv cov kua tshuaj uas muaj yaj dye. Cov porous anodic txheej absorbs cov xim. Qhov kev siv ntawm cov xim muaj feem xyuam rau yam xws li lub thickness ntawm anode zaj duab xis, dye concentration, soaking lub sij hawm thiab kub.
2. Electrolytic coloring (aka "ob-kauj ruam"): Qhov no yog cov txheej txheem siv los ntawm SAF. Tom qab anodization, cov hlau yog immersed nyob rau hauv ib da dej uas muaj inorganic hlau ntsev. Ib qho tam sim no yog siv, ua rau cov hlau ntsev tso rau hauv qab ntawm lub qhov. Cov xim kawg yog nyob ntawm cov hlau siv thiab kev ua haujlwm (qhov ntau ntawm cov xim tuaj yeem nthuav dav los ntawm kev tuag nrog cov organic dyes). Feem ntau siv hlau muaj xws li tin, cobalt, npib tsib xee thiab tooj liab.
3. Zuag qhia tag nrho Tinting: Qhov no thiaj li hu ua ib-kauj ruam txheej txheem ua ke anodizing thiab tinting rau tib lub sij hawm tsim thiab xim oxide cell phab ntsa nyob rau hauv bronze thiab dub ntxoov, thaum ua ntau hnav-resistant dua li cov pa anodizing.
4. Interference Coloring: Ib txheej txheej xim ntxiv tsis ntev los no tau qhia tias muaj kev hloov pauv ntawm lub pore qauv tsim nyob rau hauv sulfuric acid. Pore loj tshwm sim nyob rau hauv qab ntawm lub pores. Hlau deposition ntawm qhov chaw no ua rau lightfast xim xws li xiav, ntsuab, daj mus rau liab. Xim yog tshwm sim los ntawm kev cuam tshuam qhov muag pom, tsis yog lub teeb tawg ib yam li hauv cov txheej txheem xim electrolytic.
Ⅰ-C: Cov txiaj ntsig ntawm Kev Siv Cov Aluminium Anodized.
Ⅰ-C-1: Txhim kho kev zoo nkauj.
Anodizing yuav pab txhim kho kev zoo nkauj ntawm cov khoom siv aluminium sib txawv. Piv txwv li, cov khoom siv kho kom zoo nkauj ua los ntawm cov khoom siv raw no muaj cov xim anodized kom lawv tuaj yeem muaj qhov xav tau kev pom zoo rau cov neeg siv kawg.
Ⅰ-C-2: Txo cov kev tu ncua.
Cov khoom siv anodized npog lub npoo ntawm cov khoom, yog li koj tsis tas yuav txhawj xeeb txog cov teeb meem txij nkawm ntev. Yog li koj tuaj yeem yooj yim siv cov khoom kawg yam tsis muaj kev txhawj xeeb txog kev tu thiab tu. Tsis tas li ntawd, tsis zoo li cov hlau liab qab, qhov chaw anodized yuav khaws lawv cov kev ntxhib los mos rau lub sijhawm ntev yam tsis muaj khawb, abrasions, thiab lwm yam.
Ⅰ-C-3: xim ruaj khov.
Cov txheej txheem anodizing qhia kev ruaj ntseg rau cov chromium raws li cov khoom raug txhaj rau hauv cov grooves ntawm qhov chaw tsim hluav taws xob. Yog li ntawd, chromium txheej tsis raug rau corrosion ncaj qha, ntxiv kev txhim kho cov xim tuav kev ua tau zoo.
Ⅱ: Anodizing Thiab Xim Xim Xim Anodized Txhuas.
Ⅱ-A: Anodized Aluminium Basics - Txheej txheem cej luam.
Anodization ntawm txhuas yog ua raws li cov tshuaj tiv thaiv electrolytic, uas cov khoom yuav tsum tau coated ua lub anode (zoo electrode), thaum cov khoom yuav coated ua cathode (tsis zoo electrode). Cov electrolyte (cov kua ib feem ntawm lub roj teeb) feem ntau yog acidic, uas yooj yim thiab ceev cov txheej txheem.
Thaum tam sim no ntws los ntawm cov terminals mus rau hauv lub electrolyte, ib tug ionic cov tshuaj tiv thaiv tshwm sim, tsim ib txheej ntawm lub anode cov khoom nto.
Ⅱ-B: Txheej Txheem Ntawm Anodizing Txhuas Nrog Xim Xim.
Aluminium nto yog coated nrog sib txawv chromes los ntawm anodizing, series ntawm cov kauj ruam no yuav piav qhia nyob rau hauv nqe lus tom ntej. Qhov no yuav pab koj nkag siab txog dab tsi tshwm sim ntawm cov nroj tsuag thiab yuav ua li cas nws ua kom muaj kev txhim kho ntawm tag nrho cov khoom siv zog, kev ua haujlwm ntev thiab kav ntev.
Kauj Ruam 1: Nto Tu thiab Etching.
Cov khoom no yog ntxuav kom huv si hauv lub dab dej loj kom tshem tawm cov impurities ntawm lub cev ntawm cov hlau. Cov kua detergents yog siv vim lawv tsis ua leaching los yog nto corrosion ntawm cov hlau ntshiab.
Tom qab ntxuav tas, tshuab ziab khaub ncaws ntub nrog lub tshuab ziab plaub hau thiab tom qab ntawd etch. Etching yog txheej txheem los ntawm qhov chaw ntawm cov khoom sib txawv yog polished ntau zaus kom txog thaum lawv ua ci thiab du hauv kev ntxhib los mos. Tsis tas li ntawd, etching tshem tawm lwm cov cim ntawm cov hlau ntawm lub ntsej muag aluminium, vim tias lawv yuav ua rau cov tshuaj tsis tsim nyog.
Kauj Ruam 2: Siv cov txheej txheej txheej txheej nyias.
Thaum lub npoo yog etched, ib daim duab nyias nyias yog ntxiv raws li lub tsho tiv no. Txij li thaum muaj peb txheej txheem los tsim cov txheej txheem tsim no, cov txheej txheem zoo tshaj plaws yuav tsum raug xaiv los pab ua tiav txhua yam khoom thiab cov yam ntxwv. Txij li thaum txhuas feem ntau yog siv rau hauv kev tsim cov khoom hauv daim ntawv alloy, hom alloy yuav txiav txim siab qhov loj thiab cov duab ntawm daim nyias nyias pores. Ntawm qhov tod tes, electrolyte concentration, mov voltage thiab da dej kub txiav txim qhov pore qhov tob los yog tag nrho cov txheej thickness.
Kauj Ruam 3: Ntxiv Xim.
Plaub txoj kev sib txawv tau siv los ntxiv xim rau cov txheej txheem tsim ntawm aluminium nto. Nyob ntawm cov txheej txheem xaiv, ntau yam cuam tshuam, xws li:
Xim brightness
qhov tob ntawm zaj duab xis
Xim tuav peev xwm
nto smoothness
kev ntxhib los mos
Raws li qhov pom kev pom thiab lub zog ntawm cov khoom yuav nyob ntawm cov xim txheej, nco ntsoov xaiv cov txheej txheem txheej raws li qhov yuav tsum tau ua.
Kauj Ruam 4: Nto Sealing.
Sealing yog ib txwm ua thaum kawg ntawm cov txheej txheem anodizing. Txij li cov xim txheej ntxiv rau hauv daim nyias nyias yuav muaj ntau qhov pores, nws yog ib qho tseem ceeb uas yuav tsum tau kaw lawv cov chaw nres nkoj kom cov corrosive agents tsis tuaj yeem hu ncaj qha rau cov hlau qub.
Rau qhov no, hmoov dyes yog nchuav rau saum npoo ntawm cov khoom kom lawv tuaj yeem kaw tag nrho cov pores thiab tswj cov qauv thiab kev pom kev ncaj ncees.
