Ob leeg kub-dip galvanizing thiab electro-galvanizing (txias rau cov txheej txheem ntau lawm: hi lub electing zinc, thaum electro-galvanizing siv cov txheej txheem electrolytic. Dua li ntawm cov kev sib txawv no, lawv cov khoom tiav tuaj yeem tshwm sib xws. Yog li, koj tuaj yeem paub qhov txawv ntawm lawv li cas? Lawv qhov sib txawv yog dab tsi? Cia tshawb hauv qab no.
Tshooj 1: Qhov sib txawv ntawm cov kub-dip Galvanizing thiab Electro-Galvanizing
Plaster Thickness:
Kub-DIP Galvanizing tsim cov txheej zinc tuab heev, feem ntau tau tshaj 10 micrometers (μm). Qhov no muab rau kev tiv thaiv corrosion zoo heev. Txawm hais tias qhov saum npoo yog ci, nws zoo li yuav rougher thiab tej zaum yuav ua rau pom cov kab mob zinc.
Electro-galvanizing tsim tawm ntau thinner zinc txheej, feem ntau ib puag ncig 3-5 μm. Qhov saum npoo yog du tab sis feem ntau pom npub lossis greyish. Thaum nws muaj cov kev tsim kho zoo thiab cov nplaum, nws txoj kev ua kom xeb yog qhov qis dua vim yog cov nyias nyias.
Ntau lawm nplai:
Kub-DIP Galvanizing yog haum rau loj-teev, muaj ntau cov ntim ntau lawm khiav.
Electro-galvanizing feem ntau haum rau cov ntawv me me lossis qhov ntau thiab tsawg daim ntawv thov tshwj xeeb, ua rau muaj kev sib piv qis dua tag nrho cov khoom lag luam.
Nqi:
Electro-galvanizing feem ntau raug nqi ntau dua li kub-dip galvanizing. Qhov no yog vim muaj cov txheej txheem nyuaj dua thiab cov khoom zoo tshaj plaws, muaj kev muaj txiaj ntsig, thiab txheej adhesion nws muaj rau cov ntawv thov tshwj xeeb.
Txheej Txheej Txheem:
Kub-DIP galvanizing cov ntaub ntawv ntshiab zinc sab nraud. Thaum feem ntau hnav thiab pore-dawb, ib nkig hlau-zinc alloy txheej tshwm sim ntawm zinc txheej thiab cov hlau substrate.
Electro-galvanizing tso nyiaj zinc atoms ncaj qha rau ntawm cov hlau saum npoo av los ntawm electrolysis. Qhov no ua rau txheej txheej tsim ib leeg ntawm zinc, tuav ntawm lub cev ua kom zoo nkauj. Lub thinner txheej yog ntau dua zoo dua rau microscopic porosity, ua rau nws muaj qhov tsawg dua corrosion-resistant.
Ntu 2: Yuav ua li cas paub qhov txawv ntawm lawv
Los ntawm cov txheej txheem:
Hot-dip Galvanizing muaj feem xyuam ntau cov kauj ruam: degreasing tus ua haujlwm, aciding, fluxing, thiab tom qab ntawd kom qhuav rau lub sijhawm ua ntej tshem tawm. Cov khoom lag luam zoo li cov kav dej galvanized yog ib txwm ua txoj kev no.
Electro-galvanizing (txias galvanizing) siv cov khoom siv electrolytic. Lub workpiece undergoes degreasing thiab pickling, yog raus hauv zinc electrolyte tov, thiab ib qho hluav taws xob hluav taws xob. Zinc ions tso nyiaj rau hauv lub workpiece (cathode) los ua txheej txheej.
Los ntawm pom:
Kub-DIP Galvanized feem ntau tshwm me ntsis ntxhib. Nta xws li cov cim txaus, qaug cawv, lossis zinc spangles (crystalline qauv) tej zaum yuav pom, qee zaum muaj lub ntsej muag ntawm ib kawg. Cov xim yog feem ntau yog ib qho kev hnav khaub ncaws, ci silvery-dawb.
Electro-galvanized chaw feem ntau yog smoother. Cov xim tuaj yeem sib txawv, feem ntau pom cov daj daj-ntsuab, Irid-dawb, lossis dawb nrog ib zaj yeeb yaj kiab ntsuab, nyob ntawm ib qho passivation zaj duab xis thov. Cov nto yog feem ntau pub dawb los ntawm drips lossis hnyav liumps ntawm zinc.
Editor's Cov Ntsiab Lus:
Kab lus no tau teev cov qauv tseem ceeb ntawm kub-dip galvanizing thiab electro-galvanizing, nrog rau cov hau kev rau kev txheeb xyuas. Nkag siab cov kev sib txawv no yog qhov tseem ceeb yog txhua tus txheej txheem yog haum rau cov ntawv thov sib txawv. Nco ntsoov xyuas kom koj xaiv thiab siv cov hom uas tsim nyog ntawm zinc txheej rau koj cov kev xav tau tshwj xeeb.
