Qhov tsis xws luag ntawm aluminium coloring feem ntau muaj cov xwm txheej hauv qab no: lub teeb xim, xim sib txawv, dyeing, qhov chaw dawb, xim dawb, dyeing, xim dim, thiab lwm yam.Yuav daws qhov teeb meem no los xyuas kom meej tias cov xim sib txawv ntawm txhua batch ntawm cov khoom tseem zoo ib yam thiab nyob rau hauv qhov ntau ntawm deviations tau lees paub los ntawm ob tog kom ua tau raws li cov neeg siv khoom xav tau.Qhov no yuav tsum muaj cov tuam txhab tsim khoom los kawm thiab tiv thaiv cov electrochemical coloring nto kho cov profiles.
Ua rau thiab kho lub teeb xim thiab xim sib txawv
1. Lub thickness ntawm oxide zaj duab xis yog tsis sib npaug.Qhov ua tau yog tias qhov kub thiab txias ntawm anodic oxidation tank kua yog tsis sib xws.Lub sijhawm no, cov kua tank yuav tsum tau nplawm nrog cua compressed los daws cov teeb meem zoo li no.
2. Qhov kub los yog concentration ntawm cov tshuaj dye yog tsis sib npaug.Qhov kev sib tov tau qhia thiab lub sij hawm sib tov tau nce.
3, dyeing ceev ceev heev.Lub hauv qab ntawm lub workpiece ua ntej mus rau hauv lub dye tov thiab thaum kawg tawm cov dye tov, yog li hauv qab yog qhov yooj yim tshaj plaws rau dyeing sib sib zog nqus.Cov tshuaj yog kho dilute dyes, tsim nyog ncua sij hawm dyeing.
4, tsis zoo hluav taws xob conductivity.Tej zaum yuav tshwm sim los ntawm xoob hangers, xyuam xim rau cov dai yuav zam tau tej teeb meem.
5, cov xim yog nyias dhau, tuaj yeem muab ntxiv los txhim kho cov concentration.
6. Qhov kub ntawm cov tshuaj dye yog tsawg heev.Cov tshuaj zas zas tuaj yeem ua kom sov kom qis dua 60 ℃.
7, cov dye dissolves tsis tsim nyog, los yog muaj insoluble dye floating, yooj yim los tsim cov xim sib txawv.Cov tshuaj yog los txhim kho cov dye dissolution.
Ua rau thiab kev kho mob ntawm dyeing tsis ua hauj lwm
1. Tsis txaus thickness ntawm anodic oxidation zaj duab xis.Qhov kev daws teeb meem yog los xyuas seb cov txheej txheem anodic oxidation puas yog tus qauv, saib seb qhov kub, qhov hluav taws xob, conductivity thiab lwm yam zoo li cas, yog tias qhov txawv txav, thov kho cov ntsiab lus sib xws, yog tias tsis muaj abnormality, yuav tsim nyog ncua sij hawm oxidation, kom paub meej tias cov zaj duab xis thickness yog raws li tus qauv.
2. Tus nqi pH ntawm cov tshuaj dye yog siab dhau lawm, lub sijhawm no, glacial acetic acid tuaj yeem siv los kho tus nqi pH rau tus nqi tus qauv.
3. Tom qab oxidation, lub workpiece yog muab tso rau hauv lub tank ntev dhau lawm.Thov kom dyeing raws sij hawm, yog hais tias qhov teeb meem no tau tshwm sim, lub workpiece yuav muab tso rau hauv lub anodic oxidation tank los yog nitric acid neutralization tank tsim nyog ua kom cov kev kho mob thiab ces dyed, cov nyhuv yuav zoo heev.
4. Kev xaiv tsis zoo ntawm cov dyes.Cov xim zoo yuav tsum tau xaiv.
5, cov xim tau decomposed los yog moldy, lub sij hawm no yuav tsum tau hloov cov xim.
6, oxidation kub tsawg dhau, ua rau daim tawv nqaij daim tawv nqaij ntom ntom.Qhov kub ntawm oxidation tuaj yeem nce qhov tsim nyog.
7, tsis zoo hluav taws xob conductivity.Muaj peev xwm ntawm cov neeg pluag batch conduction raws li qhia los ntawm cov neeg pluag kev sib cuag ntawm anode tooj liab pas nrig los yog cathode txhuas phaj.Ua tib zoo ntxuav lub anode tooj liab pas nrig thiab cathode txhuas phaj kom zoo conductivity.
Ua thiab kho cov pob dawb thiab raug
1, dej tsis huv, dej yuav tsum muaj zog.
2. Cov dej uas siv los ntxuav yog qias neeg heev thiab yooj yim rau pollute zaj duab xis.Lub sijhawm no, cov dej yuav tsum tau hloov pauv kom ntseeg tau tias qhov zoo ntawm kev ntxuav.
3. Oxide zaj duab xis yog qias neeg los ntawm cov pa luam yeeb thiab plua plav hauv huab cua, kua qaub thiab alkali pos huab.Txhim kho kev ntxuav, dyeing raws sijhawm, kev hloov pauv raws sijhawm tuaj yeem txo cov tsos mob no.
4, oxide zaj duab xis yog qias neeg los ntawm cov roj thiab hws stains.Yuav tsum tau ntxiv dag zog rau kev tiv thaiv, tsis txhob kov lub ntsej muag ntawm lub workpiece los ntawm tes.
5. Muaj insoluble impurities nyob rau hauv cov tshuaj dye, uas yog kis los ntawm cov roj thiab ua kom puas lub dyeing ib txwm.Lub sijhawm no, cov tshuaj zas xim yuav tsum tau lim lossis hloov, thiab cov kua tank yuav tsum tau ntxuav tsis tu ncua.
6, qhov sib txawv ntawm qhov chaw ua haujlwm, qhov tob qhov seem ntawm cov kua qaub ntws tawm, kom ntxiv dag zog rau kev ntxuav ntawm cov khoom siv no.
7, Cov tshuaj zas xim yog qias neeg thiab ua rau pitting corrosion ntawm dyed workpiece.Lub sijhawm no, cov xim yuav tsum tau hloov.
Ua rau thiab kev kho mob ntawm dyeing inhomogeneity
1. Tus nqi pH ntawm cov tshuaj dye yog tsawg, thiab dilute ammonia dej tuaj yeem hloov kho rau tus qauv tus nqi.
2, kev ntxuav tsis huv. Dej yuav tsum tau ntxuav kom huv.
3, cov zas xim tsis yog yaj tag, ntxiv dag zog rau kev sib cais kom tiav dissolution.
4, dye kub yog siab dhau, txo qhov kub thiab txias.
5, oxidation zaj duab xis pore yog me me, yog vim li cas yog oxidation kub tsawg heev, inhibit daim tawv nqaij zaj duab xis yog yaj los ntawm sulfuric acid, yuav tsum tau kho kom haum rau high oxidation kub kom tsis txhob muaj teeb meem no.
6, dyeing thiab coloring ceev heev, thiab dyeing lub sij hawm luv luv, dilute dye tuaj yeem hloov kho, txo qhov kub ntawm dyeing, tsim nyog rau ncua sij hawm dyeing.
7, sealing qhov kub yog tsawg heev, cua sov tov.
8. Yog hais tias tus nqi pH ntawm lub qhov sealing tov yog tsawg dhau, kho nws mus rau tus qauv tus nqi nrog dilute ammonia dej.
9. Cov dyed nto yog ib qho yooj yim rau lwv.Qhov laj thawj tseem ceeb yog zaj duab xis ntxhib, feem ntau oxidation kub yog siab dhau lawm.Kev saib xyuas yuav tsum tau them nyiaj los tswj qhov kub ntawm oxidation nyob rau hauv tus qauv ntau.
Ntawm qhov tsis xws luag ntawm cov plaub hau oxidation coloring, coj cov kev ntsuas sib xws, qhov zoo ntawm cov xim txhuas xim yuav tsum muaj peev xwm tswj tau ruaj khov, kom ua tau raws li cov neeg siv khoom txaus siab.
