Kub-dip Galvanized yeeb nkab
Kub-dip galvanized yeeb nkab
Cov yeeb nkab kub-dip galvanized yog ua kom cov hlau molten hnov mob nrog cov hlau matrix los tsim cov txheej txheej hlau, kom cov matrix thiab txheej sib xyaw ua ke. Kub-dip galvanizing yog thawj zaug pickle cov yeeb nkab steel. 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 nrog ammonium chloride los yog zinc chloride aqueous tov los yog ib tug tov aqueous tov ntawm ammonium chloride thiab zinc chloride, thiab ces xa mus rau hauv lub kub dip plating tank. Kub-dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion thiab lub neej ua haujlwm ntev. Lub matrix ntawm kub-dip galvanized steel yeeb nkab tau dhau lub cev thiab tshuaj lom neeg cov tshuaj tiv thaiv nrog molten plating tov los tsim cov txheej txheem corrosion-resistant zinc-hlau alloy nrog cov qauv compact. Cov txheej txheej hlau yog kev sib xyaw nrog cov zinc txheej ntshiab thiab cov yeeb nkab steel matrix, yog li nws cov corrosion kuj muaj zog
Cold galvanized yeeb nkab
Cov yeeb nkab txias galvanized yog electro-galvanized, thiab tus nqi ntawm galvanizing tsawg heev, tsuas yog 10-50g / m2, thiab nws cov corrosion kuj txawv ntau dua li cov yeeb nkab kub-dip galvanized. Cov tuam txhab tsim cov yeeb nkab galvanized, txhawm rau ua kom zoo, feem ntau ntawm lawv tsis siv electro-galvanized (txias plating). Tsuas yog cov tuam txhab me me nrog cov nplai me me thiab cov cuab yeej siv tsis tu ncua siv electro-galvanization, thiab tau kawg lawv cov nqi kuj pheej yig dua. Lub Tsev Haujlwm Saib Xyuas Kev Tsim Kho tau tshaj tawm tias cov kav dej txias-galvanized nrog cov thev naus laus zis dhau los yuav tsum raug tshem tawm, thiab cov kav dej txias-galvanized tsis raug tso cai siv los ua cov kav dej thiab roj. galvanized txheej ntawm txias galvanized steel yeeb nkab yog ib txheej electroplated, thiab zinc txheej yog sib cais los ntawm steel yeeb nkab substrate. Cov zinc txheej yog nyias, thiab cov zinc txheej tsuas yog ua raws li cov yeeb nkab steel puag thiab yooj yim poob. Yog li ntawd, nws cov corrosion kuj tsis zoo. Hauv cov tsev tshiab tsim, nws yog txwv tsis pub siv cov kav dej txias galvanized ua cov kav dej.

Lus Cim: Cov khoom siv hluav taws xob ntawm cov hlau yog qhov ntsuas tseem ceeb los xyuas kom meej qhov kev siv zaum kawg (cov khoom siv tshuab) ntawm cov hlau, thiab nws nyob ntawm cov tshuaj muaj pes tsawg leeg ntawm cov hlau thiab cov cua sov. Nyob rau hauv cov txheej txheem steel yeeb nkab, raws li kev thov sib txawv, cov khoom tensile (lub zog tensile, yield zog los yog yield point, elongation), hardness thiab toughness indexes yog teev, raws li zoo raws li lub siab thiab tsis kub khoom yuav tsum tau los ntawm cov neeg siv.
