Tej teeb meem thiab kev daws teeb meem rau txhuas oxidation dyeing
Ib. Tsis tuaj yeem dyed
1. Lub thickness ntawm cov yeeb yaj kiab anodized tsis txaus. Qhov kev daws teeb meem yog los xyuas seb cov txheej txheem anodizing puas yog tus qauv thiab seb qhov kub, qhov hluav taws xob, qhov hluav taws xob thiab lwm yam zoo li cas. Yog hais tias muaj tej yam txawv txav, thov kho cov specifications raws li. Yog tias tsis muaj qhov txawv txav, lub sijhawm oxidation tuaj yeem tsim nyog txuas ntxiv kom ntseeg tau tias cov yeeb yaj kiab thickness ncav cuag tus qauv.
2. Tus nqi pH ntawm cov tshuaj dye yog siab dhau. 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 tso rau hauv lub tank dej ntev dhau lawm. Lub sijhawm dyeing tau tawm tswv yim. Yog tias qhov teeb meem no tau tshwm sim, lub workpiece tuaj yeem muab tso rau hauv lub tank anodizing lossis nitric acid neutralization tank rau kev kho kom tsim nyog ua ntej dyeing. Cov nyhuv yuav zoo heev.
4. Kev xaiv tsis raug ntawm cov dyes. Cov dyes tsim nyog yuav tsum tau xaiv.
5. Cov xim tau decomposed los yog mildewed. Lub sijhawm no, cov xim yuav tsum tau hloov.
6. Qhov kub ntawm oxidation tsawg dhau, ua rau muaj cov zaj duab xis tuab. Qhov kub oxidation tuaj yeem tsim nyog nce.
7. Tsis zoo conductivity. Tej zaum qhov hluav taws xob conductivity tsis zoo nyob rau hauv lub batch qhia los ntawm kev sib cuag tsis zoo ntawm lub anode tooj liab pas nrig los yog cathode lead phaj. Ua tib zoo saib xyuas cov anode tooj liab pas nrig thiab cathode txhuas phaj kom paub meej kev sib cuag zoo.
2. dawb pob, dew whiteness
1. Kev ntxuav dej tsis huv, yog li kev ntxuav yuav tsum muaj zog.
2. Cov dej uas siv los ntxuav yog qias neeg heev thiab tuaj yeem ua paug rau zaj duab xis yooj yim. Lub sijhawm no, cov dej yuav tsum tau hloov pauv kom ntseeg tau tias qhov zoo ntawm kev ntxuav.
3. Cov oxide zaj duab xis yog qias neeg los ntawm pa taws, kua qaub thiab alkali pos huab cua. Txhim kho kev ntxhua khaub ncaws, dyeing raws sijhawm thiab kev hloov pauv raws sijhawm tuaj yeem txo cov tsos mob no.
4. Cov oxide zaj duab xis yog kis los ntawm cov roj thiab hws stains. Kev tiv thaiv yuav tsum tau ntxiv dag zog thiab sab nrauv ntawm lub workpiece tsis tuaj yeem kov nrog tes.
5. Muaj insoluble impurities nyob rau hauv dye cawv, uas yog kis los ntawm cov roj thiab ua kom puas dyeing ib txwm. Lub sijhawm no, cov dej cawv yuav tsum tau lim lossis hloov pauv.
6. Cov kua qaub seem ntws tawm ntawm qhov khoob thiab qhov tob hauv qhov chaw ua haujlwm, thiab cov dej ntxuav ntawm cov workpieces yuav tsum muaj zog.
7. Cov dej cawv dye yog paug los ntawm Cl-, ua rau pitting corrosion ntawm dyed workpiece. Lub sijhawm no, cov xim yuav tsum tau hloov, thiab yuav tsum tau saib xyuas kom tsis txhob muaj cov impurity ions thaum lub sijhawm ua haujlwm.
3. Lub teeb xim thiab xim sib txawv
1. Tsis sib xws zaj duab xis thickness. Qhov laj thawj yog vim li cas qhov kub thiab txias ntawm cov dej anodizing da dej tsis sib xws. Cov kua da dej yuav tsum tau nplawm nrog cov cua compressed kom daws tau cov teeb meem zoo li no.
2. Qhov kub thiab txias tsis sib xws lossis concentration ntawm dye cawv. Qhia kev sib tov.
3. Lub dyeing ceev ceev heev. Hauv qab ntawm lub workpiece nkag mus rau hauv cov tshuaj zas xim ua ntej thiab tawm cov dye tov kawg, yog li hauv qab yog qhov feem ntau raug rau dyeing sib sib zog nqus. Txoj kev daws teeb meem yog dilute cov dyeing thiab ncua lub sij hawm dyeing kom tsim nyog.
4. Tsis zoo conductivity. Nws tuaj yeem tshwm sim los ntawm cov cuab yeej dai xoob. Ua tib zoo dai kom nruj kom tsis txhob muaj teeb meem zoo li no.
5. Yog tias cov dye yog nyias dhau, koj tuaj yeem ntxiv cov dye kom cov concentration.
6. Qhov kub ntawm cov tshuaj dye yog tsawg heev. Cov dej cawv dye tuaj yeem ua kom sov kom qis dua 60 degree.
7. Cov dye dissolution tsis zoo los yog floating insoluble dye tuaj yeem ua rau xim sib txawv. Txoj kev daws yog los txhim kho dye dissolution.
4. Cov plaub hau dyeing thiab xim khiav tawm
1. Tus nqi pH ntawm cov dye cawv yog nyob rau sab qis thiab tuaj yeem hloov kho rau tus qauv tus nqi nrog dilute ammonia dej.
2. Tsis huv. Ntxuav yuav tsum muaj zog.
3. Cov zas xim tsis yog yaj tag, ntxiv dag zog rau kev sib cais kom ua tiav tiav.
4. Qhov kub ntawm cov dye cawv yog siab dhau, txo qhov kub thiab txias.
5. Lub pores ntawm oxide zaj duab xis yog me me vim tias qhov kub ntawm oxidation tsawg dhau, uas inhibits cov zaj duab xis los ntawm sulfuric acid yaj. Qhov kub oxidation tuaj yeem raug tsa kom tsim nyog kom tsis txhob muaj qhov teeb meem no.
6. Cov dyeing yog ceev heev thiab lub sij hawm dyeing yog luv heev. Koj tuaj yeem kho cov tshuaj dilute dyeing, txo qhov kub ntawm dyeing, thiab ncua sij hawm dyeing kom tsim nyog.
7. Lub sealing kub yog tsawg dhau, thov kom sov nws kom daws tau qhov teeb meem.
8. Tus nqi pH ntawm cov tshuaj sealing yog tsawg dhau. Siv dilute ammonia kom nws mus rau tus nqi tus qauv.
9. Cov dyed nto yog yooj yim los so. Qhov laj thawj tseem ceeb yog tias zaj duab xis yog ntxhib, feem ntau tshwm sim los ntawm oxidation kub siab dhau lawm. Kev saib xyuas yuav tsum tau coj los tswj qhov kub ntawm oxidation nyob rau hauv qhov kev qhia tshwj xeeb.
