Kub dip galvanizing thiab txias dip galvanizing yog ob qho tib si txheej txheem ntawm zinc ua. Kub dip galvanizing suav nrog melting zinc, thaum txias dip galvanizing siv electrolysis. Lawv muaj qhov sib txawv tseem ceeb hauv kev tsim khoom, tab sis lawv cov khoom tiav kev ua haujlwm zoo sib xws. Yog li, peb yuav ua li cas thiaj paub qhov txawv ntawm lawv.
Qhov txawv ntawm kub-dip galvanizing thiab txias dip galvanizing
1. Txawv thicknesses
Lub zinc txheej ntawm kub -dip galvanizing nws tus kheej yog tuab, feem ntau nrog ib tug tuab ntawm ntau tshaj 10um, yog li nws muaj zoo anti{2}}corrosion peev xwm. Txawm hais tias saum npoo yog ci, nws yog me ntsis ntxhib thiab tej zaum yuav muaj zinc paj. zinc txheej ntawm electroplated zinc yog nyias heev, tsuas yog li 3-5um tuab. Txawm hais tias qhov saum npoo yog du, nws yuav muaj qhov tsis zoo thiab qias neeg, nrog kev ua haujlwm zoo tab sis tsis txaus corrosion kuj.
2. Cov khoom ntim sib txawv
Kub dip galvanizing belongs rau huab hwm coj ntau lawm, yog li nws muaj cov txiaj ntsig zoo. Txawm li cas los xij, galvanizing tsis tuaj yeem ua rau ntau qhov ntau, yog li nws cov zis tawm kuj tsawg.
3. Cov nqi sib txawv
Cov nyhuv saum npoo, kev ua haujlwm, thiab kev sib koom ua ke ntawm electroplated zinc yog qhov qis dua, thiab tus nqi yuav siab dua kub -dip galvanizing. Ntxiv mus, tus nqi ntawm electroplated zinc nws tus kheej yog siab dua, yog li nws tus nqi kuj siab dua.
4. Cov txheej txheem txheej txheej sib txawv
Qhov saum npoo ntawm kub -dip galvanizing belongs rau cov zinc txheej ntshiab, uas yog ib yam thiab tsis muaj pore. Txawm li cas los xij, tseem muaj ib txheej ntawm brittle compound ntawm txheej thiab substrate. Lub txheej ntawm electroplated zinc tsuas yog tsim los ntawm zinc atoms, uas yog tso thiab precipitated rau saum npoo ntawm steel sawb. Nws belongs rau lub cev adhesion thiab muaj ntau qhov pores ntawm qhov chaw, ua rau nws muaj kev cuam tshuam rau corrosion.
Lawv tuaj yeem txawv ntawm ntau yam
1. Sib txawv ntawm cov txheej txheem
Muaj ntau cov txheej txheem ua rau kub -dip galvanizing, uas yuav tsum tau lub workpiece kom degreased, acid ntxuav, impregnated, thiab qhuav ua ntej yuav muab raus rau hauv lub pas dej ua ke zinc. Tom qab ib lub sij hawm ntawm immersion, nws muaj peev xwm muab rho tawm, uas yog txheej txheem ntawm kub -dip galvanizing. Qee qhov kub -dip galvanized yeeb nkab fittings yog ua tiav li no. Txias galvanizing yog qhov tseeb electroplating, uas yog ua tiav siv cov khoom siv electrolytic. Tom qab ua tiav cov txheej txheem xws li tshem tawm cov roj thiab cov kua qaub ntxuav, nws yog immersed nyob rau hauv ib qho kev daws teeb meem uas muaj zinc ntsev, txuas nrog cov khoom siv electrolytic, thiab muab tso rau hauv zinc txheej ntawm lub workpiece thaum lub sij hawm kev taw qhia ntawm qhov zoo thiab tsis zoo electrodes.
2. Paub qhov txawv ntawm qhov tsos
Tag nrho cov tsos ntawm kub -dip galvanizing yog me ntsis rougher, nrog rau cov tsos ntawm cov txheej txheem dej kab, tee dej, thiab lwm yam cim, tshwj xeeb tshaj yog nyob rau hauv ib kawg ntawm lub workpiece, uas yog pom meej nyiaj dawb tag nrho. Qhov saum npoo ntawm electroplated zinc yog tus du, feem ntau daj ntsuab, tab sis kuj muaj cov xim xws li zaj sawv, xiav dawb, thiab dawb nrog lub teeb ntsuab. Tag nrho cov workpiece yeej tsis muaj zinc nodules, clumps, lossis lwm yam tshwm sim.
