Aluminium alloy yog dav siv vim nws lub teeb yuag, corrosion kuj, thiab siab zog-rau-hnyav piv. Txawm li cas los xij, dhau sijhawm, txheej txheej aluminium oxide ntawm qhov chaw tuaj yeem ua qias neeg lossis npub, cuam tshuam rau nws cov tsos thiab kev ua haujlwm. Nov yog ob peb txoj hauv kev los ntxuav cov aluminium alloy oxide txheej zoo.
1. Mechanical Cleaning:
Kev tu tshuab yog siv cov ntaub ntawv abrasive, xws li cov ntawv xuab zeb lossis cov ntaub plaub hlau, los txhuam cov txheej txheej aluminium oxide. Txoj kev no tshem tawm cov av av, stains, thiab oxidation. Nws yog ib qho tseem ceeb uas yuav tau siv cov tshuaj txhuam hniav kom tsis txhob ua rau cov hlau hauv qab. Tom qab ntawd, aluminium yuav tsum tau muab yaug kom huv si thiab qhuav.
2. Tshuaj ntxuav:
Kev tu tshuaj yog lwm txoj hauv kev zoo los ntxuav cov txheej txheem aluminium alloy oxide. Cov kua qaub lossis alkaline tuaj yeem siv tau, nyob ntawm qhov hnyav ntawm oxidation. Cov tshuaj ntxuav kua qaub, xws li vinegar los yog kua txiv qaub, tuaj yeem yaj cov tawv nqaij tawv thiab lub teeb oxidation. Alkaline ntxuav, zoo li sodium hydroxide lossis ci dej qab zib, ua haujlwm zoo rau oxidation hnyav. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li kev ceev faj txog kev nyab xeeb thiab kev sib cais kom raug thaum siv tshuaj.
3. Electrolytic Cleaning:
Electrolytic tu yog ib txoj hauv kev uas siv hluav taws xob tam sim no tshem tawm cov txheej txheem txhuas oxide. Cov txheej txheem no, tseem hu ua anodizing, suav nrog submerging cov txhuas hauv cov tshuaj, feem ntau yog cov kua qaub lossis alkali, thiab siv cov tam sim no ncaj qha. Tam sim no cuam tshuam cov txheej txheem oxide, tso cai rau nws kom huv si yooj yim. Electrolytic tu yog qhov ua tau zoo tab sis yuav tsum muaj cov cuab yeej tshwj xeeb thiab yuav tsum tau ua los ntawm cov kws tshaj lij.
4. Chav ntxuav:
Kev ntxuav chav dej yog ib txoj hauv kev yooj yim thiab siv tau los ntxuav cov txheej txheem aluminium alloy oxide yam tsis tas siv cov tshuaj hnyav lossis cov abrasives. Cov chav kub kub thiab siab siab pab tshem tawm cov av, stains, thiab oxidation zoo. Txoj kev no yog siv dav hauv kev lag luam thiab kev lag luam, tab sis cov khoom siv tes ua haujlwm kuj tseem siv tau rau cov khoom me me lossis cov khoom siv txhuas hauv tsev.
Hauv kev xaus, kev tswj xyuas qhov huv thiab zoo ntawm aluminium alloy los ntawm kev ntxuav nws cov oxide txheej yog qhov tseem ceeb. Txawm hais tias los ntawm kev tu txhua yam, tshuaj ntxuav, tshuaj electrolytic tu, los yog chav ntxuav, nws yog ib qho tseem ceeb uas yuav tau xaiv txoj kev uas haum rau cov av thiab oxidation. Kev tu thiab tu tsis tu ncua yuav pab ua kom lub neej ntev thiab kev ua haujlwm ntawm cov khoom siv aluminium alloy.
