Kub dip galvanizing, tseem hu ua galvanizing, yog ib txoj kev ntawm immersing hlau Cheebtsam nyob rau hauv molten zinc kom tau ib tug hlau txheej.Electro galvanizing feem ntau hu ua "txias galvanizing" los yog "dej galvanizing";Nws siv electrochemistry, siv zinc ingot ua anode.Cov zinc atoms poob lawv cov electrons thiab ua ions thiab yaj rau hauv cov electrolyte, thaum cov khoom siv hlau ua raws li anode.Ntawm lub cathode, zinc ions tau txais electrons los ntawm cov hlau thiab raug txo rau zinc atoms uas tau tso rau saum npoo ntawm cov hlau kom ua tiav cov txheej txheem uas cov txheej txheej ua ib qho zoo, ntom, thiab zoo-bonded hlau lossis alloy deposition txheej. Kab lus no yuav muab rau koj piav qhia tob txog qhov sib txawv ntawm ob.
1. Txawv txheej thicknesses
Qhov kub dip galvanized txheej feem ntau muaj cov zinc txheej tuab, txog 40 μm lossis ntau dua, lossis txawm tias siab li 200 μm lossis ntau dua.Cov txheej kub dip galvanized feem ntau yog 10 mus rau 20 npaug ntawm cov txheej electroplated zinc.Lub electroplated zinc txheej yog nyias heev, txog 3-15μm, thiab txheej hnyav tsuas yog 10-50g / m2.
2. Cov nqi sib txawv ntawm galvanizing
Tus nqi galvanizing ntawm kub dipped galvanized steel coils tsis tuaj yeem yog me me.Feem ntau, qhov tsawg kawg nkaus yog 50 ~ 60g / m2 ntawm ob sab thiab qhov siab tshaj plaws yog 600g / m2.galvanized txheej ntawm electro galvanized steel coils tuaj yeem nyias nyias, nrog tsawg kawg yog 15g / m2.Txawm li cas los xij, yog tias cov txheej txheem yuav tsum tau ua kom tuab, cov kab ntau lawm yuav qeeb heev, uas tsis haum rau cov txheej txheem ntawm cov cuab yeej niaj hnub no.Feem ntau, qhov siab tshaj plaws yog 100g / m2.Vim li no, kev tsim cov nplooj ntawv electro galvanized steel yog heev txwv.
3. Cov txheej txheem txheej yog txawv
Muaj ib qho me ntsis brittle compound txheej ntawm cov ntshiab zinc txheej ntawm cov ntawv kub dip galvanized thiab steel phaj matrix.Thaum cov zinc txheej ntshiab crystallizes, feem ntau ntawm cov paj zinc yog tsim, thiab txheej txheej yog sib xws thiab tsis muaj pores.Cov zinc atoms nyob rau hauv electroplated zinc txheej tsuas yog precipitated rau saum npoo ntawm cov hlau phaj, thiab yog lub cev txuas rau saum npoo ntawm cov hlau sawb.Muaj ntau qhov pores, uas tuaj yeem yooj yim ua rau pitting corrosion vim corrosive media.Yog li ntawd, kub dip galvanized daim hlau yog ntau resistant tshaj electro galvanized daim hlau corrosion.
4. Cov txheej txheem kev kho cua sov sib txawv
Kub dipped galvanized steel nplooj ntawv feem ntau yog ua los ntawm cov hlau tawv tawv thiab txuas ntxiv annealed thiab kub dip galvanized ntawm txoj kab galvanizing.Cov hlau sawb yog rhuab rau lub sijhawm luv luv thiab tom qab ntawd txias, yog li lub zog thiab plasticity raug cuam tshuam rau qee yam.Nws qhov kev ua tau zoo stamping zoo dua li tib lub phaj nyuaj yog txawv los ntawm cov phaj txias txias tom qab degreasing thiab annealing hauv cov kab ntau lawm.Kub dipped galvanized steel los xij muaj cov nqi tsim khoom qis dua thiab dav siv ntau yam, thiab tau dhau los ua ntau yam tseem ceeb hauv kev ua lag luam galvanized.Electro galvanized steel los xij siv cov ntawv txias dov steel los ua cov ntaub ntawv raw, uas yeej lav tau qhov kev ua haujlwm ntawm cov ntawv txias txias, tab sis nws cov txheej txheem nyuaj kuj nce nqi ntau lawm.
5. Qhov txawv txav
Qhov saum npoo ntawm cov kub dip galvanized txheej yog ntxhib thiab ci, thiab nyob rau hauv cov xwm txheej hnyav muaj zinc paj;electro galvanized txheej yog du thiab grey (stained).
6. Sib txawv ntawm daim ntawv thov thiab txheej txheem
Kub-dip galvanizing yog tsim rau cov khoom loj thiab cov khoom siv;kub-dip galvanizing yog kom pickle cov yeeb nkab steel ua ntej.Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov yeeb nkab steel, tom qab pickling, nws tau dhau los ntawm ammonium chloride los yog zinc chloride aqueous tov los yog ammonium chloride thiab chlorine.Zinc tov aqueous tov tank rau tu, thiab ces xa mus rau lub kub dip plating tank.
Kub dipped galvanized steel kauj muaj kev tiv thaiv zoo, tuab txheej, thiab tsis muaj av suav nrog.Nws muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion thiab kev pab lub neej ntev.Kub-dip galvanizing muaj kev tiv thaiv zoo rau atmospheric corrosion ntawm lub hauv paus hlau hlau tshaj electro-galvanizing.
Galvanized steel los ntawm electroplating muaj kev ua tau zoo, tab sis cov txheej yog nyias thiab corrosion kuj tsis zoo li cov ntawv kub dipped galvanized steel ntawv;cov zinc txuas rau electro galvanized steel coilis me me, thiab tsuas yog cov yeeb nkab phab ntsa sab nrauv yog galvanized, thaum kub-dip galvanizing yog ob sab hauv thiab sab nraud.
