Cov teeb meem thiab kev daws teeb meem hauv Aluminium Anodizing thiab xim
Ib. Siv tsis tau xim
1. Tsis txaus thickness ntawm cov yeeb yaj kiab anodized. Qhov kev daws teeb meem yog los xyuas seb cov txheej txheem anodizing puas yog tus qauv, thiab tshuaj xyuas seb yam xwm txheej zoo li qhov kub thiab txias, qhov hluav taws xob, thiab conductivity puas ruaj khov. Yog tias pom qhov txawv txav, kho thiab ua raws li tus qauv. Yog tias tsis pom muaj teeb meem, lub sijhawm oxidation tuaj yeem txuas ntxiv kom tsim nyog kom ntseeg tau tias cov yeeb yaj kiab thickness ua tau raws li tus qauv.
2. Tus nqi pH ntawm cov tshuaj dye yog siab dhau. Hauv qhov no, siv glacial acetic acid los kho cov pH rau tus nqi tus qauv.
3. Lub workpiece tau tso rau hauv lub tank dej ntev dhau lawm tom qab oxidation. Nws raug nquahu kom zas xim tam sim. Yog tias qhov no tau tshwm sim lawm, lub workpiece tuaj yeem muab tso rau hauv lub tank anodizing lossis nruab nrab lub tank nrog nitric acid rau kev ua kom zoo ua ntej dyeing, uas yuav tau txais txiaj ntsig zoo.
4. Kev xaiv xim tsis raug. Xaiv cov xim uas tsim nyog.
5. Cov xim tau decomposed los yog pwm. Hauv qhov no, hloov cov xim.
6. Oxidation kub tsawg dhau, ua rau cov yeeb yaj kiab ntom ntom. Qhov kub oxidation tuaj yeem tsim nyog nce.
7. Tsis zoo conductivity. Qhov no tuaj yeem yog vim kev sib cuag tsis zoo ntawm anodic tooj liab pas nrig lossis cathodic txhuas phaj, ua rau muaj teeb meem kev sib txuas. Nco ntsoov ntxuav lub anodic tooj liab pas nrig thiab cathodic txhuas phaj kom paub meej kev sib cuag zoo.
2. Cov pob dawb thiab cov seem dawb
1. Yog tias kev ntxuav nrog dej tsis huv, kev ntxhua khaub ncaws yuav tsum tau siv zog.
2. Yog tias cov dej uas siv los ntxuav yog qias neeg heev, nws tuaj yeem ua rau cov txheej txheem yooj yim. Hauv qhov no, cov dej yuav tsum tau hloov pauv kom ntseeg tau tias ntxuav tau zoo.
3. Cov yeeb yaj kiab oxide tuaj yeem ua paug los ntawm cov pa taws, acidic, lossis alkaline pos huab hauv huab cua. Txhim kho kev ntxhua khaub ncaws, dyeing raws sijhawm, thiab hloov pauv sai tuaj yeem txo qhov teeb meem no.
4. Oxide films tuaj yeem kis tau los ntawm cov roj lossis hws. Kev tiv thaiv yuav tsum tau ua kom muaj zog, thiab qhov chaw ntawm lub workpiece yuav tsum tsis txhob kov ntawm tes.
5. Yog hais tias cov tshuaj zas zas muaj undissolved impurities los yog kis los ntawm cov roj, ib txwm dyeing yuav cuam tshuam. Hauv qhov no, cov xim yuav tsum tau lim lossis hloov.
6. Cov kua qaub seem yuav nyob hauv qhov khoob lossis qhov tob ntawm lub workpiece. Rau xws li workpieces, ntxuav yuav tsum tau intensified.
7. Yog tias cov tshuaj zas zas xim muaj paug nrog Cl-, nws tuaj yeem ua rau pitting corrosion ntawm dyed workpiece. Hauv qhov no, cov xim yuav tsum tau hloov. Hauv kev ua haujlwm txhua hnub, yuav tsum tau saib xyuas kom tsis txhob muaj cov impurity ions.
3. Lub teeb xim, xim txawv
1. Tsis sib xws txheej thickness. Qhov ua tau yog qhov tsis sib xws ntawm qhov kub thiab txias hauv chav dej anodizing. Qhov no tuaj yeem daws tau los ntawm kev siv cua compressed los do lub da dej.
2. Tsis sib xws dye da dej kub lossis concentration. Qhia ib txoj kev nplawm.
3. Dyeing sai heev. Hauv qab ntawm lub workpiece nkag mus rau hauv cov xim da dej ua ntej thiab tawm kawg, yog li hauv qab yog feem ntau nws yuav tsaus. Txoj kev daws teeb meem yog dilute cov dyeing thiab tsim nyog ncua lub sij hawm dyeing.
4. Tsis zoo conductivity. Qhov no tej zaum yuav tshwm sim los ntawm xoob fixtures; ua kom lawv nruj tuaj yeem tiv thaiv qhov teeb meem no.
5. Dye yog dilute heev. Koj tuaj yeem ntxiv cov xim ntau ntxiv kom muaj zog ntxiv.
6. Dye da dej kub yog tsawg dhau. Lub dye da dej tuaj yeem ua kom sov kom qis dua 60 degree.
7. Kev zas xim tsis zoo los yog cov xim tsis zoo uas tsis muaj dej ntws hauv da dej tuaj yeem ua rau xim sib txawv. Txoj kev daws yog los txhim kho cov dye dissolution.
4. Tsis sib xws dyeing los yog xim los ntshav
1. Yog tias pH ntawm cov tshuaj dye yog tsawg dhau, nws tuaj yeem hloov kho rau tus qauv tus nqi siv dilute ammonia.
2. Kev tu tsis tiav. Txhim kho kev ntxuav.
3. Cov xim tsis yaj tag. Txhim kho kev sib cais kom txog thaum yaj tag.
4. Cov tshuaj zas xim kub siab heev. Txo qhov kub thiab txias.
5. Cov pores me me hauv oxide zaj duab xis, tshwm sim los ntawm qhov kub thiab txias, tiv thaiv cov yeeb yaj kiab los ntawm sulfuric acid yaj. Qhov kub oxidation tuaj yeem tsim nyog nce kom tsis txhob muaj qhov teeb meem no.
6. Dyeing tshwm sim sai heev, thiab lub sij hawm dyeing luv dhau. Dilute cov tshuaj zas xim, txo qhov kub ntawm dyeing, thiab tsim nyog ncua lub sij hawm dyeing.
7. Sealing kub tsawg dhau. Ua kom kub kom daws tau qhov teeb meem.
8. pH ntawm cov kua sealing tsawg heev. Kho rau tus qauv tus nqi siv dilute ammonia.
9. Dye rau saum npoo yooj yim rubs tawm. Qhov laj thawj tseem ceeb yog cov yeeb yaj kiab ntxhib, feem ntau tshwm sim los ntawm qhov kub siab oxidation ntau dhau. Ua tib zoo saib xyuas qhov kub ntawm oxidation nyob rau hauv tus qauv ntau.
