Tu cov kauj ruam rau kev kho oxide rau tshuaj aluminium:

A. Txhuam cov dej ntom ntom ntub dej (degreased) Cov hnoos qeev: yuav tsum muaj ob lub dej ntxuav, txhuas oxidation cov ntsiab lus yog ntxuav cov khoom residue ntawm cov kua (los yog kua qaub los yog alkali, yog cov tshuaj hnyuv tshem tawm hnyav emulsifier Tu tseem ceeb.) Los yog oily. Tiv thaiv kom tsis txhob nkag mus rau hauv cov dej ntws tawm mus tom qab da dej ua rau muaj kev ruaj ntseg ntawm lub da dej thiab tiv thaiv kom tsis txhob muaj cov kab mob ua kom muaj roj nrog ua rau cov khoom puas. Ob qhov dej ntxuav tau siv tau yam tsis muaj phwj lawm, thiab nws yog ib qho zoo rau kev pauv qhov haujlwm raws li kev ua haujlwm.
B. Dej ntxuav tom qab alkali etching: Yuav tsum tau muaj li peb dej ntxuav. Lub hom phiaj yog ntxuav lub nrig alkali etching tank cov kua tshuaj ntxiv nyob rau ntawm cov alkali-etched txhuas. Vim tias nws tsis yooj yim rau kev ntxuav, nws yog qhov pom zoo kom txo cov naj npawb ntawm cov dej hloov los ua kom muaj qhov kub thiab alkalinity, uas yog siv cov khoom tu. . Yog hais tias muaj tej yam kev mob hauv qab ob lub tso tsheb hlau luam, lub txhuas khoom tsim hluav taws xob tuaj yeem ua rau kom cov nyhuv zoo dua. Ob qhov dej ntxuav tau siv tau yam tsis muaj phwj lawm, thiab nws yog ib qho zoo rau kev pauv qhov haujlwm raws li kev ua haujlwm.
C. Cov tshuaj siv (electrolytic) polishing tom qab ntxuav: Nws tuaj yeem ntxuav ob zaug. Lub hom phiaj ntawm txhuas oxidation coloring yog ntxuav cov kua khov ntawm cov txhuas hniav. Nws raug pom zoo tias thawj lub tank yuav tsum muaj qhov kub thiab txias los pab txhawb nqa khoom. . Qhov thib ob lub dab dej tuaj yeem raug ntxuav nrog cov dej mus rau kom zoo dua. (Tom qab electrolysis, nws yog ib qho tsim nyog yuav tau ua kom cov txheej txheem muab tshem tawm thiab tom qab ntawd ntxuav ob zaug)
Aluminium oxidation kho ntawm frosted npuag profiles: frosted txhuas profiles zam cov disadvantages ntawm aluminium alloy profiles hauv kev siv ntawm hniav chaw, nyob rau hauv tej yam kev mob ntawm lub teeb cuam, nws nto yog li ilv thiab muag li brocade, nrov heev nyob rau hauv kev ua lag luam Tsaj, tab sis cov ntaub ntawv uas twb ua abrasive yuav tsum tau kov yeej tsis muaj qhov tsis sib xws ntawm cov xuab zeb hauv av thiab tuaj yeem pom qhov tsis txaus ntawm tus qauv.
