Niaj hnub no, nrog rau kev siv cov hlau ntau zuj zus, yuav ua li cas kom cov hlau ruaj khov hauv cov av noo, tshuaj tsuag ntsev, chaw ua haujlwm thiab lwm qhov chaw yog qhov tseem ceeb hauv kev tsim khoom thiab kev yuav khoom. Txawm hais tias nws tab tom tsim cov khoom tsim, kev ua cov txee, lossis cov khoom siv hauv tsev thiab cov railings tiv thaiv, kev kho galvanized tau dhau los ua kev tiv thaiv ntau tshaj - txoj kev xeb. Txawm li cas los xij, nws zoo li "kub dip galvanizing" thiab "electro-galvanizing" tsuas yog qhov sib txawv ntawm cov txheej txheem, tab sis muaj qhov sib txawv pom tseeb hauv txoj cai tiv thaiv corrosion, txheej txheej thiab cov xwm txheej siv tau.
1.Cov txheej txheem txheej txiav txim siab qhov sib txawv ntawm corrosion kuj ntawm lawv.
The core function of zinc plating is to use zinc to form a dense oxide film in the air, and to protect the steel matrix through "sacrificial anode" after zinc is destroyed.
Kub dip galvanizing: tsim metallurgical bonding txheej, uas yog ntau ruaj.
Kub dip galvanizing yog muab cov hlau rau hauv zinc kua ntawm li 450 degree, kom cov zinc txheej reacts nrog cov hlau matrix los ua ntau- txheej Fe-Zn alloy txheej.
Cov yam ntxwv ntawm cov qauv no yog:
- Cov txheej yog "alloyed" nrog lub substrate, thiab adhesion muaj zog heev.
- Lub thickness feem ntau loj, xws li Z275 (275 g / m) yog ib qho qauv.
- Tseem tuaj yeem tuav kev tiv thaiv ntev thaum ntsib kev khawb.
Yog li ntawd, kev pab cuam lub neej ntawm kub dip galvanizing tuaj yeem ncav cuag 10-30 xyoo sab nraum zoov, tshwj xeeb tshaj yog nyob rau hauv seaside thiab siab ntsev ib puag ncig.
Galvanizing: Lub cev tso nyiaj nrog "thin but uniform" tiv thaiv.
Galvanizing tso cai rau zinc kom sib npaug ntawm cov hlau los ntawm electrolysis, thiab txheej yog "lub cev txuas" rau cov hlau substrate.
- Cov txheej yog nyias, feem ntau 5-20μ m.
- Qhov saum npoo yog ci thiab du, haum rau cov khoom uas muaj qhov xav tau siab.
- Tab sis qhov corrosion kuj yog pom tseeb tsis muaj zog dua li ntawm kub dip galvanizing.
Nws yog qhov tsim nyog rau sab hauv tsev lossis me ntsis corrosive ib puag ncig, xws li cov khoom siv hauv tsev, kho vajtse, cov khoom siv tshuab thiab lwm yam.
2.Vim li cas qhov kev pab cuam lub neej ntawm kub galvanizing ntev dua li ntawm electro-galvanizing?
- Lub thicker lub txheej, qhov kev siv qeeb qeeb.
- Lub alloy txheej ntawm molten zinc yog qhov nyuaj rau tev tawm.
- Qhov "sacrificial anode tiv thaiv" cov nyhuv ntawm kub dip galvanizing yog pom tseeb ntau dua li cov txheej nyias.
Hauv tib qhov chaw, kev sim sab nraum zoov pom tau tias:
Lub neej kev pab cuam ntawm Z275 kub-dip galvanizing feem ntau yog 5-10 npaug ntawm cov galvanization zoo tib yam.
3.Qhov kev xaiv logic ntawm ob hauv daim ntawv thov scenario.
Kub dip galvanizing yog ntau haum rau:
- Sab nraum zoov guardrail, steel qauv
- Tsheb thauj mus los (teeb ncej, kev txhawb nqa, suab thaiv)
- Kev sib kis ntauwd, kev txhawb nqa photovoltaic
- Khoom siv nyob rau hauv seaside thiab corrosive ib puag ncig
- Loj welded qhov chaw thiab engineering structural qhov chaw
Cov xwm txheej no tau them nyiaj ntau rau "durability" thiab "tus nqi saib xyuas qis".
Galvanizing yog tsim nyog:
- Plhaub thiab sab hauv phaj ntawm cov khoom siv hauv tsev
- Hardware thiab fasteners
- Tsheb sab hauv vaj huam sib luag
- Cov khoom siv sab hauv tsev thiab lub teeb corrosive ib puag ncig
- Precision qhov chaw nrog siab zoo li xav tau
Nws qhov zoo dua yog tias qhov saum npoo yog finer thiab qhov loj yog yooj yim los tswj.
4. Cov ntsiab lus
Qhov tseem ceeb sib txawv ntawm kub galvanizing thiab electrogalvanizing nyob rau hauv lawv "txheej txheem" thiab "corrosion resistance mechanism".
Ib qho yog "metallurgical ua ke, loj thickness thiab ntev kev pab cuam lub neej",
Ib qho yog "deposition rau hauv zaj duab xis, zoo li zoo thiab siv zoo".
Ntev npaum li cov txheej txheem tsim nyog raug xaiv raws li kev siv ib puag ncig, kev pabcuam lub neej ntawm cov hlau tuaj yeem txhim kho tau zoo thiab cov nqi kho tom qab tuaj yeem txo qis.
