Dab tsi "Kub Dip Galvanized" Tiag Tiag
Kub dip galvanizing yog txheej txheem metallurgical, tsis yog xim pleev xim lossis tshuaj tsuag txheej. Ib qho kev tsim los yog ua ntej- ua steel hollow seem yog ntxuav los ntawm ib ntu ntawm degreasing, acid pickling, thiab fluxing da dej rau strip zeb nplai, roj, thiab oxidation mus rau liab qab hlau. Cov seem uas tau ntxuav yog ces muab tso rau hauv ib da dej ntawm molten zinc, feem ntau nyob ib ncig ntawm 450℃(840℃F). Cov zinc tsis yog zaum saum cov hlau - nws reacts metallurgically nrog cov hlau nyob rau hauv steel nto, ua ib tug series ntawm zinc- hlau alloy txheej topped los ntawm ib txheej ntawm cov zinc ntshiab. Qhov tshwm sim yog txheej txheej uas yog metallurgically sib raug zoo rau lub hauv paus hlau, tsis yog mechanically adhered li xim, uas yog vim li cas galvanized coatings tiv thaiv chipping, tev, thiab abrasion zoo dua li feem ntau siv txheej.
Muaj ob txoj hauv kev tsim khoom tsim nyog paub qhov txawv:
- Batch (post-fabrication) kub dip galvanizing, qhov twg ib ntu - qee zaum tag nrho welded los ua ke - yog dipped tom qab txiav, drilling, thiab vuam tiav. Qhov no muab tag nrho cov txheej txheem ntawm kev txiav xaus, weld seams, thiab drilled qhov.
- Hauv -kab (nruam) galvanizing, qhov chaw tiaj tus steel strip yog galvanized ua ntej nws yob - ua rau hauv raj, ces welded kaw. Qhov no tshwm sim rau sib dua - ntsuas fencing thiab ua liaj ua teb tube, tab sis tawm hauv cov vuam seam thiab txiav xaus nrog thinner los yog tsis muaj zinc them tshwj tsis yog tias cov txheej txheem thib ob yog siv.
Rau cov qauv kev ua haujlwm qhov kev tiv thaiv corrosion ntawm kev txiav xaus thiab welds tiag tiag, batch kub dip galvanizing feem ntau yog cov txheej txheem los nrhiav - nws yog ib qho khoom sib txawv ntawm cov raj txuas txuas ntxiv, txawm tias ob leeg tau hu ua "galvanized" hauv kev sib tham tsis tu ncua.
Txheej Nyhav thiab Thickness yuav tsum tau
Kev lag luam kev coj ua teeb tsa qhov nruab nrab txheej txheej txheej tsawg kawg nkaus raws li cov hlau cov tuab tuab, txij li cov khoom thinner nce mus txog qhov kub thiab txias dua thiab coj txawv ntawm zinc da dej ntau dua li qhov hnyav. Tus neeg sawv cev yam tsawg kawg nkaus rau cov qauv duab thiab cov raj -zoo li cov khoom poob hauv qhov dav dav:
| Steel Thickness qeb | Yam tsawg kawg nruab nrab txheej tuab |
|---|---|
| Hauv qab 1/16 nti (1.6 mm) | ~ 1.2m (35 µm) |
| 1/16 "- 1/8" (1.6-3.2 hli) | ~ 1.5 mil (45 µm) |
| Tshaj 1/8 nti rau 3/16 nti (3.2–4.8 mm) | ~ 2.0mil (50 µm) |
| 3/16 nti (4.8mm) | ~ 2.2 mil (55 µm) |
Ib txwm paub meej cov duab kos nrog koj tus neeg muag khoom, txij li cov txheej txheem txheej txheej yog feem ntau categorized los ntawm cov khoom siv hauv paus nrog rau cov tuab, thiab cov duab tuaj yeem sib txawv ntawm cov neeg tsim khoom thiab tau hloov kho lub sijhawm.

Ntev npaum li cas Kub Dip Galvanizing Tiag Tiag?
Zinc tiv thaiv steel ob txoj kev: nws ua raws li lub cev barrier, thiab - tseem ceeb tshaj - nws ua raws li ib tug sacrificial anode, corroding nyiam los tiv thaiv tej me me ntawm cov hlau raug (ntawm ib tug txiav ntug los yog me me txheej puas, piv txwv li) los ntawm galvanic ua. Kev pab cuam lub neej nyob ntawm qhov hnyav ntawm atmospheric exposure qeb:
- Nyob deb nroog / teeb pom kev lag luam: coatings feem ntau kav ntau xyoo lawm ua ntej yuav tsum tau saib xyuas thawj zaug
- Suburban / nruab nrab industrial: me ntsis luv dua, tab sis feem ntau yog ntau- xyoo caum kev pab cuam lub neej
- Marine / ntug hiav txwv dej los yog hnyav industrial cua: corrosion tus nqi ntawm zinc yog sai dua, yog li cia siab tias yuav luv dua, txawm tias tseem muaj ntau, lub sijhawm ua haujlwm ua ntej kov- nce lossis rov ua dua yog lav
Lub koom haum American Galvanizers thiab cov koom haum sib piv thoob ntiaj teb luam tawm cov ntaub ntawv zinc corrosion los ntawm thaj chaw raug yog tias koj xav ua qauv kev pab cuam lub neej rau ib qhov chaw tshwj xeeb.
FAQ
Q: Qhov txawv ntawm kub dip galvanized thiab electro-galvanized (zinc{1}}plated) hollow seem yog dab tsi?
A: Kub dip galvanizing immerses steel nyob rau hauv molten zinc, ua ib tug tuab, metallurgically bonded txheej feem ntau zoo tshaj 1 mil tuab. Electro-galvanizing deposits ib tug ntau thinner zinc txheej electrochemically, feem ntau nyob rau hauv 0.5 mil, uas muaj deb tsawg corrosion kuj thiab feem ntau yog npaj rau sab hauv tsev los yog lub teeb- daim ntaub ntawv es tsis yog cov qauv siv sab nraum zoov.
Q: Puas yog kub dip galvanized hollow seem yuav welded rau ntawm qhov chaw?
A: Yog, tab sis vuam kub hnyiab tawm cov zinc txheej hauv tshav kub - cuam tshuam thaj chaw thiab tso cov pa zinc uas yuav tsum tau ua kom muaj cua thiab tiv thaiv ua pa thaum vuam. Tom qab vuam, thaj chaw cuam tshuam yuav tsum tau kho nrog zinc- nplua nuj txias galvanizing compound lossis metallized zinc txau kom rov qab tiv thaiv corrosion ntawm qhov chaw ntawd
Q: Puas yog kub dip galvanizing cuam tshuam lub zog ntawm lub hollow seem?
A: Lub galvanizing da dej kub yog qhov zoo hauv qab qhov ntau yam uas yuav ua rau lub hauv paus steel lub microstructure los yog txhua yam khoom nyob rau hauv cov qauv carbon steels, yog li yield thiab tensile zog tseem tswj hwm los ntawm lub hauv paus specification (feem ntauASTM A500 1los yogA53), tsis yog txheej txheem txheej.
Q: Puas yog kub dip galvanized hollow seem haum rau ncaj qha embedment?
A: Zinc tuaj yeem cuam tshuam nrog cov pob zeb tshiab thaum kho, tsim cov roj hydrogen thiab tshuaj lom neeg ntawm zinc nto; Qhov no feem ntau tswj tau nrog kev nthuav dav kom zoo (xws li kev kho chromate passivation los yog tso cai rau kev kho kom zoo) thiab yog ib qho kev coj ua, tab sis nws tsim nyog lees paub cov kev xav tau nthuav dav nrog tus kws tshaj lij corrosion rau cov ntawv thov tseem ceeb lossis hnyav heev.
