Ob txheej txheej Galvanizing sib txawv
Galvanizing yog siv zinc txheej rau hlau los tiv thaiv corrosion. Kub-dip galvanizing immerses cov ntawv hlau nyob rau hauv ib da dej ntawm molten zinc ntawm li 450 degrees Celsius, thaum electrostatic galvanizing deposits zinc los ntawm ib tug electrolyte mus rau lub steel nto los ntawm electrolysis. Cov npe qee zaum luv luv rau kub-dip thiab electro-galvanizing.
Txawm hais tias ob qho tib si txheej txheem xaus nrog zinc txheej, txheej txheej thickness, qauv thiab kev ua tau zoo sib txawv hauv paus, thiab ob txoj kev siv rau ntau yam khoom.
Kub-Dip Galvanizing
Hauv cov txheej txheem kub -dip cov hlau yog ntxuav, pickled thiab fluxed, ces muab tso rau hauv molten zinc. Cov zinc reacts nrog cov hlau nto thiab tsim ib tug series ntawm zinc- hlau alloy txheej npog los ntawm ib txheej ntawm cov zinc ntshiab, uas ua ke muab tag nrho cov txheej thickness ntawm feem ntau 45 mus rau 85 microns rau cov qauv hlau.
Lub tuab, metallurgically bonded txheej tiv thaiv cov hlau los ntawm ob lub tshuab: nws ua raws li kev tiv thaiv kev ya raws thiab oxygen, thiab nws corrodes nyiam dua li kev txi anode thaum lub txheej yog khawb. Kev tiv thaiv kav ntev li kaum xyoo hauv kev pabcuam sab nraum zoov, uas yog vim li cas kub -dip galvanizing yog teev rau cov qauv steelwork, transformer tso tsheb hlau luam thiab xa cov yees rau cov qauv xws li ISO 1461 thiab ASTM A123.
Electrostatic Galvanizing
Electrostatic galvanizing, zoo dua hu ua electro-galvanizing, tso ib txheej nyias ntawm cov zinc ntshiab ntawm cov hlau hauv da dej electrolytic. Cov txheej thickness feem ntau yog 5 mus rau 25 microns, ntau thinner dua kub -dip, thiab qhov saum npoo yog du thiab sib xws nrog lub ntsej muag ci.
Vim hais tias cov txheej yog nyias thiab ntshiab zinc tsis muaj cov txheej txheem alloy, nws ua rau lub neej luv dua corrosion dua kub -dip rau tib qhov chaw. Electro- cov ntawv galvanized yog li ntawd siv rau qhov chaw zoo nkauj tiav, cov xim zoo adhesion los yog ze rau qhov ntev ntev, xws li fasteners, automotive panels, hluav taws xob enclosures thiab me me.
Kev sib piv ntawm Cov Khoom Tseem Ceeb
| Khoom | Kub-Dip Galvanizing | Electrostatic Galvanizing |
|---|---|---|
| Txheej thickness | 45 mus rau 85 microns raug | 5 mus rau 25 microns |
| Txheej txheej | Zinc- hlau alloy txheej ntxiv rau cov zinc ntshiab | Zinc ntshiab |
| Nto tiav | Rough, spangled | Smooth thiab ci |
| Corrosion lub neej | Xyoo caum sab nraum zoov | Luv luv, feem ntau hauv tsev |
| Yam khoom | Cov qauv hlau, tso tsheb hlau luam, yees | Fasteners, panels, me me qhov chaw |
Yuav Ua Li Cas Xaiv Txoj Kev Zoo
Qhov kev xaiv yog nyob ntawm qhov xav tau kev pab cuam lub neej, ib puag ncig thiab cov khoom zoo li. Rau cov qauv sab nraum zoov, lub tank hloov pauv thiab cov khoom siv uas yuav tsum muaj sia nyob tau ntau xyoo nrog kev saib xyuas me ntsis, kub -dip galvanizing yog tus qauv xaiv thiab raug them los ntawm ISO 1461.
Rau qhov me me, cov ntawv kho kom zoo nkauj thiab cov khoom siv uas cov txheej yuav tsum tsis txhob hloov qhov ntev lossis cov xov haum, electrostatic galvanizing yog qhov zoo dua. Qhov twg ob qho tib si xav tau, ib lub tshuab duplex ntawm kub -dip galvanizing ntxiv rau xim tuaj yeem siv los ua ke lub neej ntev nrog qhov zoo nkauj zoo nkauj.
Cov lus nug nquag
Q: Txoj kev galvanizing twg muab kev tiv thaiv corrosion zoo dua?
A: Kub-dip galvanizing muab kev tiv thaiv zoo dua vim tias txheej txheej yog ob mus rau tsib zaug tuab dua thiab yog metallurgically sib raug zoo rau cov hlau. Nyob rau hauv tib qhov chaw, kub-dip txheej ntawm 70 microns tuaj yeem siv tau rau ntau xyoo lawm, thaum lub 10 micron electro- galvanized txheej tiv thaiv rau ob peb xyoos nkaus xwb.
Q: Ob txheej txheem tuaj yeem siv rau tib yam khoom?
A: Lawv feem ntau yog lwm txoj hauv kev, tsis suav nrog. Cov khoom yog immersed nyob rau hauv molten zinc los yog coated electrolytically. Rau kev tiv thaiv siab tshaj plaws, kub -dip galvanizing yog ua raws li los ntawm kev pleev xim rau hauv duplex system es tsis yog los ntawm electro-galvanizing.
Q: Vim li cas kub -dip galvanizing tawm ntawm qhov ntxhib spangled?
A: Cov ntaub ntawv spangle li cov zinc molten solidifies ntawm cov hlau, thiab cov roughness los ntawm kev loj hlob ntawm zinc crystals thiab zinc- hlau alloy txheej. Qhov saum npoo yog qhov ua haujlwm zoo dua li cov hniav zoo nkauj thiab tuaj yeem smoothed los ntawm cov txheej txheem tom ntej yog tias xav tau.
Q: ISO 1461 txhais li cas?
A: ISO 1461 qhia cov tuab, cov qauv thiab cov qauv kev sim rau kub -dip galvanized txheej ntawm fabricated hlau thiab steel khoom. Nws txhais qhov tsawg kawg nkaus txheej thickness qhov tseem ceeb uas nyob ntawm seb lub thickness ntawm cov hlau raug coated.
Q: Puas yog electrostatic galvanizing haum rau siv sab nraum zoov?
A: Cov txheej nyias nyias tsis pom zoo rau qhov ntev - tawm sab nraum zoov. Electro-galvanized qhov chaw nyob rau sab nraum zoov yuav tsum tau pleev xim los yog hmoov coated, los yog ib tug thicker kub-dip txheej yuav tsum tau xaiv.
