Qhov sib txawv ntawm electrogalvanized thiab kub dip galvanized
Raws li txoj kev sib dhos, galvanized steel kauj tuaj yeem muab faib ua kub-dip galvanized steel kauj thiab electro-galvanized steel kauj.
Kub dip galvanizing thiab electrogalvanizing tsis tsuas yog muaj txheej txheej txheej txheej txheej txheem, txheej txheem ntau lawm, tab sis kuj muaj cov khoom sib txawv thiab kev siv.
Kub dip galvanizing tuaj yeem yog txoj kev tiv thaiv hlau corrosion. Tom qab pretreatment, cov galvanized hlau los yog cov ntaub ntawv uas tsis yog-hlau yog immersed nyob rau hauv kua metallic zinc, thiaj li hais tias lub nto ntawm cov khoom steel adheres rau zinc txheej, yog li txhim kho corrosion kuj ntawm cov ntaub thiab txhim kho cov kev ua tau zoo ntawm cov ntaub.
Txias galvanizing yog ua kom du thiab ntom hlau txheej los ntawm electrolysis kom tau raws li qhov xav tau ntawm cov khoom siv hlau thiab cov khoom tsis yog hlau.
1. Txheej txheem
Kev tsim cov txheej txheem kub dip galvanizing yog: ua ntej- plating → degreasing → ntxuav → stripping → ntxuav → extrusion → dej soluble → ziab → galvanizing → txias → straightening → oiling → ntim.
Cov txheej txheem yooj yim ntawm electrogalvanizing yog raws li hauv qab no: ua ntej-galvanizing ntawm qhov chaw → degreasing → corrosion → polishing → galvanizing → hydrogen tshem tawm → passivation / dyeing.
2. Tus nqi
Piv nrog electro-galvanized steel, kub-dip galvanized steel muaj tib yam corrosion kuj, tab sis cov nqi sib dhos ntawm electro-galvanized steel yog siab dua li ntawm kub-dip galvanized steel.
3. Qhov zoo
Cov khoom kub-dip galvanized muaj cov txiaj ntsig ntawm cov zinc txheej tuab, zoo corrosion kuj, zoo nkauj tsos, haum rau kev ua haujlwm ntxiv, tus nqi qis thiab txo qis ib puag ncig.
Electrogalvanizing muaj cov txiaj ntsig zoo ntawm formability, zoo weldability thiab txheej, zoo nto zoo, thiab tsis hloov cov khoom siv ntawm cov phaj pib thaum lub sij hawm sib dhos.
Qhov sib txawv ntawm cov khoom tiav galvanized:
1. Cov phab ntsa sab hauv thiab sab nrauv ntawm cov yeeb nkab kub-dip galvanized steel yeeb nkab yog galvanized, thaum sab nrauv phab ntsa ntawm cov yeeb nkab txias-dipped galvanized steel yeeb nkab tsuas yog galvanized;
2. Cov txheej txheej txias yog sib xws thiab yog li ntawd lub thickness yog incredibly nyias; Cov txheej tshiab yog tuab dua thiab cov tuab yog tsis sib xws.
3. Cov tsos ntawm txias plating yog ci, thiab cov xim ntawm kub plating yog tsaus dua.
4. Vim tias cov txheej txheej txias yog thinner, corrosion kuj tsis zoo; Cov txheej tsis ntev los no yog kaum ob lub sij hawm thicker dua txias galvanizing, thiab tsim ib txheej infiltration nrog hauv qab hlau, uas muaj corrosion kuj zoo.
5. Qhov saum npoo ntawm kub-dip galvanized steel yeeb nkab zoo li ci dua thiab smoother; Qhov saum npoo ntawm kub-dip galvanized steel yeeb nkab tsis yog qhov muag heev thiab ci ntsa iab zoo li txias-dip galvanized steel yeeb nkab.
