1. Anodizing
Anodizing yog cov txheej txheem siv dav siv rau cov txheej txheem aluminium alloy uas tsim cov txheej txheem oxide txheej ntawm cov hlau.Cov txheej txheem koom nrog anodizing (electrolytic oxidation) ntawm txhuas hauv cov kua qaub.Lub thickness ntawm oxide txheej tuaj yeem tswj tau, thiab cov txheej txheem ua tau nyuaj dua li cov hlau hauv qab.Cov txheej txheem no kuj tseem siv tau los ntxiv cov xim rau aluminium alloys los ntawm kev siv ntau yam dyes.Anodizing muab kev txhim kho corrosion, hnav tsis kam, thiab txhim kho kev puas tsuaj.Tsis tas li ntawd, nws tuaj yeem ua kom tawv tawv thiab tuaj yeem txhim kho adhesion ntawm txheej.
2. Chromate Conversion Txheej
Chromate hloov dua siab tshiab txheej yog txheej txheem kho saum npoo uas siv cov txheej txheem chromate hloov dua siab tshiab rau saum npoo ntawm aluminium alloy.Cov txheej txheem yuav immersing lub txhuas alloy qhov chaw nyob rau hauv ib tug daws ntawm chromic acid los yog dichromate, uas tsim ib tug nyias txheej ntawm chromate hloov dua siab tshiab txheej rau saum npoo ntawm cov hlau.Cov txheej feem ntau yog daj lossis ntsuab, thiab nws muab kev tiv thaiv corrosion zoo dua, ntxiv adhesion rau xim, thiab lub hauv paus zoo dua rau adhesion rau lwm cov txheej.
3. Pickling (Etching)
Pickling (etching) yog cov txheej txheem tshuaj lom neeg ntawm qhov chaw kho mob uas cuam tshuam nrog cov txhuas alloys hauv cov kua qaub kom tshem tawm cov impurities ntawm qhov chaw thiab tsim kom muaj kev ntxhib los mos.Cov txheej txheem suav nrog kev siv cov kua qaub heev, xws li hydrochloric lossis sulfuric acid, kom tshem tawm cov txheej txheej ntawm cov hlau.Cov txheej txheem no tuaj yeem tshem tawm cov khoom seem lossis cov oxide txheej ntawm aluminium alloy nto, txhim kho qhov sib xws, thiab muab cov substrate zoo dua rau txheej adhesion.Txawm li cas los xij, nws tsis txhim kho corrosion kuj, thiab qhov saum npoo tuaj yeem ua rau muaj kev cuam tshuam corrosion thiab lwm yam kev puas tsuaj yog tias tsis muaj kev tiv thaiv zoo.
4. Plasma Electrolytic Oxidation (PEO)
Plasma Electrolytic Oxidation (PEO) yog txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej txheej.Cov txheej txheem cuam tshuam nrog cov khoom siv aluminium alloy nyob rau hauv ib qho electrolyte, thiab tom qab ntawd siv hluav taws xob tam sim no rau cov khoom, uas ua rau muaj kev cuam tshuam oxidation tshwm sim.Qhov tshwm sim oxide txheej muab kev hnav zoo heev, tiv thaiv corrosion, thiab nce hardness.
5. Hmoov Txheej
Hmoov txheej yog txheej txheem kev kho saum npoo nrov rau aluminium alloys uas koom nrog ntxiv txheej tiv thaiv hmoov rau saum npoo ntawm cov hlau.Cov txheej txheem cuam tshuam nrog kev txau cov xim sib xyaw ntawm cov xim thiab cov ntawv khi rau saum npoo ntawm cov hlau, tsim kom muaj cov yeeb yaj kiab cohesive uas kho tau ntawm qhov kub thiab txias.Lub resulting hmoov txheej muab ib tug ruaj, khawb-resistant, thiab corrosion-resistant tag.Nws muaj nyob rau hauv ntau yam xim, textures, thiab finishes, ua rau nws ib tug zoo tagnrho tov rau ntau daim ntaub ntawv.
Xaus
Hauv kev xaus, cov txheej txheem kho saum npoo tau hais los saum toj no tsuas yog qee qhov piv txwv ntawm ntau cov txheej txheem siv los kho aluminium alloys.Txhua qhov kev kho mob no muaj nws cov txiaj ntsig tshwj xeeb, thiab koj daim ntawv thov xav tau yuav txiav txim siab seb qhov kev kho mob twg zoo tshaj rau koj qhov project.Txawm li cas los xij, tsis hais txog cov txheej txheem kev kho mob twg siv, qhov tseem ceeb tshaj plaws yog ua kom muaj kev saib xyuas kom zoo rau kev npaj thiab ntxuav kom zoo.Los ntawm kev xaiv txoj kev kho saum npoo zoo, koj tuaj yeem txhim kho qhov zoo li, durability, thiab kev ua tau zoo ntawm koj cov khoom siv aluminium alloy, uas ua rau cov khoom lag luam zoo nyob rau lub sijhawm ntev.
