Galvanized hlau

Galvanized steel kavtau muab faib ua txias galvanized steel kav thiab kub-dip galvanized steel kav.Cov kav dej txias galvanized steel tau raug txwv.Nyob rau xyoo 1960 thiab 1970, cov teb chaws tsim kho hauv ntiaj teb tau pib tsim cov kav dej tshiab thiab maj mam txwv cov kav dej galvanized.Plaub lub tuam tsev thiab cov thawj coj suav nrog Ministry of Construction ntawm Tuam Tshoj kuj tau tshaj tawm cov ntaub ntawv hais tias cov kav dej galvanized raug txwv tsis pub siv los ua cov kav dej txij li xyoo 2000. Cov kav dej txias hauv cov zej zog uas tau tsim tshiab tsis tshua siv cov kav dej galvanized, thiab qee qhov dej kub. cov kav dej hauv qee cov zej zog siv cov kav dej galvanized.Kub-dip galvanized steel kav muaj ntau yam kev siv hauv kev tiv thaiv hluav taws, hluav taws xob thiab kev loj.

Daim ntawv thov

Kub-dip galvanized steel kav yog siv dav hauv kev tsim kho, tshuab, thee mines, tshuaj, hluav taws xob, tsheb ciav hlau, tsheb kev lag luam, kev loj, txuas hniav, ntim khoom, chaw ua si, kev ua liaj ua teb, roj av machinery, prospecting machinery, tsev cog khoom siv thiab lwm yam. kev lag luam.

Galvanized steel yeeb nkab yog welded steel yeeb nkab nrog kub-dip galvanized lossis electro-galvanized txheej ntawm qhov chaw.Galvanizing tuaj yeem ua rau muaj kev tiv thaiv corrosion ntawm cov kav hlau steel thiab ua rau lub neej ua haujlwm ntev.Galvanized kav yog dav siv.Ntxiv rau kev siv los ua cov kav dej rau cov kua dej uas tsis tshua muaj siab xws li dej, roj, thiab roj, lawv kuj tseem siv tau los ua cov kav dej thiab cov kav dej hauv cov roj av, tshwj xeeb tshaj yog nyob rau sab ntug dej hiav txwv, thiab cov roj cua sov thiab cov kav dej. hauv cov khoom siv tshuaj coking.Cov kav dej txias, thee distillation ntxuav cov roj sib hloov, thiab cov kav dej rau trestle pawg, txhawb nqa thav duab rau mine tunnels, thiab lwm yam.

Cov lus qhia ntxaws

Kub dipgalvanized yeeb nkab

Kub-dip galvanized yeeb nkab yog ua kom cov hlau molten hnov ​​​​mob nrog cov hlau matrix los tsim cov txheej txheej hlau, kom cov matrix thiab txheej ua ke.Kub-dip galvanizing yog xaiv cov yeeb nkab steel ua ntej.Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov yeeb nkab steel, tom qab pickling, nws yog ntxuav nyob rau hauv lub tank ntawm ammonium chloride los yog zinc chloride aqueous tov los yog tov aqueous tov ntawm ammonium chloride thiab zinc chloride, thiab ces xa mus rau hauv lub da dej kub.Kub-dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion thiab lub neej ua haujlwm ntev.Kub-dipgalvanized steel yeeb nkabsubstrate undergoes complex lub cev thiab tshuaj tiv thaiv nrog molten plating tov los tsim ib tug corrosion-resistant zinc-hlau alloy txheej nrog ib tug compact qauv.Cov txheej txheej hlau yog kev sib xyaw nrog cov zinc txheej ntshiab thiab cov yeeb nkab steel substrate, yog li nws muaj zog corrosion kuj.

Cold galvanized yeeb nkab

Cov yeeb nkab txias galvanized yog electro-galvanized, thiab cov nyiaj galvanized tsawg heev, tsuas yog 10-50g / m2.Nws cov corrosion kuj txawv ntau dua li cov yeeb nkab kub-dip galvanized.Txhawm rau kom ntseeg tau qhov zoo, feem ntau cov kav dej galvanized tsis tu ncua tsis siv electro-galvanized (txias plating).Tsuas yog cov lag luam me nrog cov cuab yeej siv tsis tu ncua siv electrogalvanizing, thiab tau kawg lawv cov nqi kuj pheej yig.Lub Tsev Haujlwm Saib Xyuas Kev Tsim Kho tau tshaj tawm tsab ntawv xaj kom tshem tawm cov kav dej txias galvanized nrog cov thev naus laus zis niaj hnub, thiab tsis txhob siv cov kav dej txias galvanized rau cov kav dej thiab cov kav dej.galvanized txheej ntawm txias galvanized steel yeeb nkab yog txheej txheej electroplating, thiab zinc txheej yog nws tus kheej txheej nrog cov yeeb nkab steel substrate.Cov zinc txheej yog nyias, thiab cov zinc txheej tsuas yog ua raws li cov yeeb nkab steel substrate thiab yooj yim poob tawm.Yog li ntawd, nws cov corrosion kuj tsis zoo.Hauv cov tsev tshiab, nws raug txwv tsis pub siv cov kav dej txias galvanized ua cov kav dej.
