Kub-dip galvanizing yog ib txoj hauv kev zoo rau kev tiv thaiv corrosion hlau.Nws immerses steel khoom nyob rau hauv molten zinc kua los ua ib tug zinc-hlau alloy txheej thiab ib tug ntshiab zinc txheej nyob rau saum npoo ntawm cov hlau, yog li muab kev tiv thaiv corrosion zoo.Txoj kev no yog siv dav hauv kev tsim kho, tsheb, hluav taws xob, kev sib txuas lus thiab lwm yam kev lag luam los tiv thaiv steel qauv, kav dej, fasteners, thiab lwm yam.
Cov kauj ruam yooj yim ntawm cov txheej txheem kub-dip galvanizing yog raws li hauv qab no:
Degreasing thiab ntxuav
Cov hlau nto ua ntej yuav tsum tau ntxuav kom huv si kom tshem tawm cov roj, av thiab lwm yam impurities.Qhov no feem ntau yog ua los ntawm immersing cov hlau nyob rau hauv ib tug alkaline los yog acidic tov tom qab ib tug txias dej yaug.
Flux txheej
Tom qab ntawd cov hlau ntxuav yog muab tso rau hauv 30% zinc ammonium tov ntawm 65-80°C.Lub hom phiaj ntawm cov kauj ruam no yog siv cov txheej txheem ntawm cov dej los pab tshem tawm cov oxides ntawm cov hlau thiab xyuas kom meej tias cov zinc molten tuaj yeem ua rau cov hlau zoo dua.
Galvanizing
Cov hlau yog immersed nyob rau hauv molten zinc ntawm qhov kub ntawm txog 450°C. Lub sijhawm immersion feem ntau yog 4-5 feeb, nyob ntawm qhov loj thiab thermal inertia ntawm cov hlau.Thaum lub sij hawm tus txheej txheem no, cov hlau nto chemically reacts nrog cov zinc molten.
Txias
Tom qab kub-dip galvanizing, cov hlau yuav tsum tau txias.Lub ntuj cua txias los yog txias ceev los ntawm quenching tuaj yeem xaiv, thiab cov txheej txheem tshwj xeeb nyob ntawm qhov kawg ntawm cov khoom..
Kub-dip galvanizing yog ib qho kev tiv thaiv corrosion zoo rau cov hlau, muab cov txiaj ntsig tseem ceeb:
●Tus nqi qis dua: Tus nqi pib thiab mus sij hawm ntev ntawm kub-dip galvanizing feem ntau qis dua lwm cov txheej tiv thaiv corrosion, ua rau nws muaj kev xaiv pheej yig.
●Lub neej ua haujlwm ntev heev: Cov txheej txheej galvanized tuaj yeem tiv thaiv cov hlau tsis tu ncua rau ntau tshaj 50 xyoo thiab tiv thaiv corrosion zoo.
●Tsawg dua kev saib xyuas yuav tsum tau: Txij li cov txheej txheej galvanized yog tus kheej tu thiab tuab dua, nws muaj cov nqi tu qis thiab lub neej ua haujlwm ntev.
●Tsis siv neeg tiv thaiv qhov chaw puas: Cov txheej txheej galvanized muab kev tiv thaiv kev txi, thiab thaj chaw me me ntawm kev puas tsuaj tsis tas yuav kho ntxiv.
●Kev tiv thaiv tag nrho thiab ua tiav: Kub-dip galvanizing kom ntseeg tau tias txhua qhov chaw, suav nrog thaj chaw nyuaj mus txog, muaj kev tiv thaiv tag nrho.
●Ib qho yooj yim los soj ntsuam: Cov xwm txheej ntawm cov txheej txheej galvanized tuaj yeem raug soj ntsuam los ntawm kev tshuaj xyuas yooj yim.
●Faster installation:Kub-dip galvanized steel cov khoom tau npaj siv thaum lawv tuaj txog ntawm qhov chaw ua haujlwm, tsis tas yuav tsum tau npaj los yog tshuaj xyuas ntxiv.
● Daim ntawv thov ceev ntawm cov txheej txheem tag nrho: Cov txheej txheem kub-dip galvanizing yog ceev thiab tsis cuam tshuam los ntawm huab cua, ua kom muaj kev hloov pauv sai.
Cov txiaj ntsig zoo no ua rau kub-dip galvanizing qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv corrosion steel, uas tsis tsuas yog txhim kho lub neej kev pab cuam thiab kev ua haujlwm ntawm cov hlau, tab sis kuj txo cov nqi tag nrho thiab kev ua haujlwm.
Qhov chaw nthuav tawm ntawm qhov kawg fittings (nrog rau flange ntsej muag) ntawm lubCDSR roj suction thiab tawm hosesKev tiv thaiv los ntawm kub-dip galvanizing raws li EN ISO 1461, los ntawm corrosion los ntawm seawater, ntsev pos huab thiab kis nruab nrab.Raws li kev lag luam roj thiab roj txuas ntxiv mus nrhiav kev txhim kho kom ruaj khov, daim ntawv thov kub-dip galvanizing thev naus laus zis tsis tsuas yog txhim kho corrosion kuj ntawm cov cuab yeej siv thiab txuas ntxiv nws lub neej kev pab cuam, tab sis kuj txo qis kev siv cov peev txheej thiab cov khoom pov tseg los ntawm kev txo qhov zaus ntawm kev hloov khoom siv. vim corrosion.
