Kub-dip galvanized steel kav thiab txias-galvanized steel kav muaj qhov sib txawv ntawm ntau yam, raws li tau piav qhia hauv qab no:
1. Cov txheej txheem sib txawv
Kub-dip Galvanized Steel Pipes: Cov txheej txheem kub-dip galvanizing yog kev kho lub cev nrog cov tshuaj electrochemical. Nws koom nrog kev xaiv cov kav hlau kom tshem tawm cov hlau oxide saum npoo, ces muab tso rau hauv cov zinc molten, qhov twg cov txheej txheem alloy tsim los ntawm cov tshuaj tiv thaiv ntawm cov hlau thiab cov hlau molten, khov kho cov txheej txheem rau lub substrate. Cov txheej txheem no ua kom cov txheej txheej tsis sib xws, muaj zog adhesion, thiab lub neej ua haujlwm ntev.
Cold-Galvanized Steel Pipes: Kuj hu ua electro-galvanizing, qhov no yog txheej txheem kev kho tshuaj. Nws siv cov khoom siv electrolytic los ntxuav thiab khaws cov kav hlau ua ntej muab tso rau hauv cov zinc ntsev tov, qhov twg cov txheej txheem electrolytic tso ib txheej zinc rau ntawm cov yeeb nkab saum npoo. Txawm li cas los xij, cov txheej no tsuas yog ua raws li cov yeeb nkab ntawm qhov chaw tsis muaj tshuaj lom neeg cov tshuaj tiv thaiv nrog cov substrate, ua rau nws yooj yim rau flaking tawm.
2.Coating Thickness thiab Corrosion Resistance
Kub-dip Galvanized Steel Pipes: Nrog rau txheej txheej thickness feem ntau tshaj li ob peb puas microns, kub-dip galvanized kav muaj zog corrosion kuj, zoo tiv taus ntau yam corrosive ib puag ncig.
Cold-Galvanized Steel Pipes: Featuring ib txheej nyias ntawm ob peb mus rau ntau tshaj kaum microns, cov kav dej txias-galvanized muaj qhov tsis muaj zog tiv thaiv corrosion, tsis tuaj yeem ua rau cov kav dej kub-dip galvanized.
3.Qhov tsos thiab du
Kub-Dip Galvanized Steel Pipes: Cov kav dej no muaj qhov pom me ntsis rougher dua li cov kav dej electro-galvanized, tshwm silvery-dawb nrog cov txheej txheem muaj peev xwm thiab me me drips, tshwj xeeb tshaj yog pom ntawm ib kawg ntawm lub workpiece. Txawm li cas los xij, tag nrho txheej txheej yog uniform nrog muaj zog adhesion.
Cold-Galvanized Steel Pipes: Cov kav dej txias-galvanized khav theeb zoo dua thiab ci dua sab nrauv. Thaum siv cov txheej txheem xim xim, cov plating feem ntau tshwm daj-ntsuab nrog cov xim zaj sawv. Txawm li cas los xij, nyob rau hauv cov ces kaum thiab cov npoo ntawm cov workpieces complex, "hluav taws xob hlawv" tuaj yeem ua rau dull grey thaj ua rau thaj ua rau cov zinc txheej tuab, thaum cov chaw tuag nyob rau hauv cov ces kaum yuav ua rau dull grey cheeb tsam nrog thinner zinc txheej.
4. Nqe thiab daim ntawv thov
Nqe: Vim yog cov txheej txheem ntau lawm thiab txheej txheej zoo, cov kav dej kub-dip galvanized steel feem ntau kim dua cov kav dej txias-galvanized. Cov kav dej txias-galvanized, nrog cov nqi tsim khoom qis, feem ntau yog siv los ntawm cov lag luam nrog cov khoom siv tsis tu ncua thiab cov nplai me me.
Daim ntaub ntawv: Kub-dip galvanized steel kav, renowned rau lawv exceptional corrosion kuj, yog dav siv nyob rau hauv kev tsim kho, tshuaj, roj av, natural gas, thiab lwm yam sectors. Conversely, cov kav dej txias-galvanized, nrog rau kev tiv thaiv corrosion tsis zoo, tau raug txwv nruj los ntawm lub teb chaws txoj cai los ntawm kev siv rau hauv cov chaw tseem ceeb xws li cov kav dej thiab cov kav dej, tab sis tseem yuav pom cov ntawv thov hauv cov chaw uas tsis muaj kev txwv nruj dua.
Nyob rau hauv xaus, kub-dip galvanized steel kav thiab txias-galvanized steel kav sib txawv nyob rau hauv cov nqe lus ntawm txheej txheem, txheej thickness, corrosion kuj, tsos, smoothness, nqi, thiab daim ntawv thov. Thaum xaiv ntawm ob hom kav dej, kev xav zoo yuav tsum tau muab rau cov kev xav tau tshwj xeeb thiab cov xwm txheej.
