Dab tsi yog galvanized steel yeeb nkab?

Galvanized yeeb nkab, tseem hu ua galvanized steel yeeb nkab, muab faib ua kub-dip galvanizing thiab electro-galvanizing. Cov txheej kub-dip galvanizing yog tuab, nrog cov txheej txheem plating, muaj zog adhesion thiab ua haujlwm ntev. Tus nqi ntawm electroplating yog tsawg, qhov saum npoo tsis du heev, thiab nws cov corrosion kuj yog qhov phem dua li cov kav dej kub-dip galvanized.

Kub dip galvanized yeeb nkab
Lub molten hlau yog reacted nrog ib tug hlau matrix los tsim ib tug alloy txheej, yog li combining lub substrate thiab plating txheej. Kub-dip galvanizing yog khaws cov yeeb nkab steel ua ntej, txhawm rau tshem tawm cov hlau oxide ntawm cov yeeb nkab steel, tom qab pickling, nws yog ntxuav los ntawm ammonium chloride los yog zinc chloride aqueous tov los yog tov aqueous tov ntawm ammonium chloride thiab zinc chloride, thiab ces noj. Kub dip plating tank. Kub-dip galvanizing muaj qhov zoo ntawm cov txheej txheem plating, muaj zog adhesion thiab lub neej ua haujlwm ntev. Feem ntau ntawm cov txheej txheem sab qaum teb siv galvanized strips ncaj qha coil zinc.

Cold galvanized yeeb nkab
Txias galvanizing yog electrogalvanizing. Tus nqi ntawm galvanizing yog tsawg heev, tsuas yog 10-50g / m2, thiab nws cov corrosion kuj yog ntau dua li cov kav dej kub-dip galvanized. Tsis tu ncua galvanized yeeb nkab manufacturers, txhawm rau kom zoo, feem ntau tsis siv electro-galvanizing (txias plating). Tsuas yog cov tuam txhab me me nrog cov khoom siv me me thiab cov cuab yeej qub siv electro-galvanized steel, tau kawg, lawv cov nqi kuj pheej yig dua. Hauv cov tsev tshiab, kev siv cov kav dej txias-galvanized steel yeeb nkab yog txwv tsis pub siv cov kav dej.

Qhov sib txawv kub-dip galvanizing thiab txias galvanizing

Kub dip galvanizing txheej txheem:
Workpiece degreasing → ntxuav → pickling → ntxuav → ziab hnyav dip fluxing preheated kub dip galvanized → txias → tiav → yaug → ziab → passivation xeem

Txias- galvanized txheej txheem:
Tshuaj degreasing → ntxuav → dej kub dej kub electrolysis degreasing → ntxuav → ntxuav → muaj zog corrosive galvanized hlau alloy → ntxuav → ntxuav → teeb → → ntxuav → ziab passivation

TEEB MEEM ntawm kub-dip galvanizing thiab txias galvanizing

Txias galvanizing zoo nkaus li du, ci, xim passivation txheej txheem plating txheej yog daj-ntsuab hauv cov xim, muaj yeeb yuj. Plating txheej yog bluish-dawb los yog dawb nrog dawb passivation txheej txheem yog ntsuab, dawb txheej passivation txheej txheem thiab lub hnub yog tseem ceeb muaj yeeb yuj lub kaum sab xis. Lub complex workpiece angular edges feem ntau "hluav taws xob hlawv" los ntawm kev tsaus muag, qhov chaw ntawm zinc txheej tuab. Yin ces kaum qhov chaw yog ib qho yooj yim los tsim ib tug tam sim no tuag undercurrent grey cheeb tsam thiab cheeb tsam zinc txheej yog thinner. Lub workpiece zuag qhia tag nrho zinc qog, caking phenomenon.

Kub dip galvanized saib me ntsis ntxhib piv rau electro-galvanized, silvery dawb, saib cov txheej txheem waterlines thiab ob peb tee ntawm qog yog pom tseeb dua, tshwj xeeb tshaj yog nyob rau hauv ib kawg ntawm lub workpiece. Kub dip galvanized zinc txheej dua li ob peb zaug ntawm electro-galvanized tuab corrosion tiv thaiv yog ob peb zaug ntawm electro-galvanized.
