Niaj hnub no, cov kav dej kub-dip galvanized steel kav yog hom kev tswj hluav taws kub, thiab lawv tau ua tiav cov txiaj ntsig tsis tuaj yeem hloov pauv hauv kev lag luam kev nyab xeeb hluav taws. Vim li cas ho tsis tuaj yeem hloov cov yeeb nkab kub-dip galvanized los ntawm cov kav hlau uas pheej yig dua lossis cov kav dej txias galvanized?
Lub thermal galvanized creation tau tsim nyob rau hauv nruab nrab -18th caug xyoo. Nws tau ua los ntawm txoj kev loj hlob ntawm cov txheej txheem kub-plating txheej txheem, thiab nws yog ntau tshaj 300 xyoo ntawm keeb kwm lub sij hawm. Txog rau hnub no, kub-dip galvanized tseem yog ib qho kev siv dav thiab kev ua haujlwm zoo hauv kev ntsuas steel.
Lub hauv paus ntsiab lus ntawm galvanized steel nyob ntawm: tshwj tsis yog rau thawj txheej ntawm kev pab them nqi tsim, ntxiv rau corrosion ntawm cov pa roj thiab noo noo ntawm cov yeeb nkab steel, cov hlau yog hluav taws xob ntau dua li cov hlau ntau dua li zinc. Txuag lub zinc txheej los tiv thaiv cov hlau sab hauv. Yog li ntawd, qhov kev tiv thaiv corrosion ua haujlwm muaj peev xwm ntawm cov kav dej dav hlau tsis tuaj yeem ntes tau. Txawm hais tias cov hlau uas tau daws los ntawm kev tiv thaiv corrosion xws li kev siv cov xim, kev ua haujlwm corrosion kuj tsis tuaj yeem muab piv nrog cov yeeb nkab kub galvanized.
Lub galvanized txheej ntawm kub-dip galvanized yeeb nkab yog lub plhaub npog nrog txheej txheej ntawm cov yeeb nkab steel tom qab soaking, thiab cov yeeb nkab txias galvanized yog ib zaj duab xis yas tsim raws li cov tshuaj tiv thaiv electrolytic. Yog li ntawd Qhov kev ncua deb yog siab tshaj qhov txias-dip galvanized yeeb nkab. Los ntawm cov hauv paus ntsiab lus ntawm galvanizing steel los tswj cov hlau, peb tuaj yeem nkag siab tias cov txheej txheej galvanized thicker, zinc ntau dua, qhov kev tiv thaiv zoo dua ntawm cov hlau. Yog li ntawd, lub thickness ntawm cov galvanized txheej yog deb tshaj li kub-dip galvanized steel yeeb nkab ntawm sab nraud, thiab corrosion kuj yog kaum ob lub sij hawm txias galvanized steel yeeb nkab.
Vim yog tib qho laj thawj, txheej txheej ntawm cov kav dej kub galvanized yog coated zoo. Lub adhesion ntawm galvanized txheej yog zoo dua li txias-dip galvanized yeeb nkab. Lub siab adhesion txhais tau hais tias cov txheej galvanized tsis yooj yim rau kev puas tsuaj vim qhov cuam tshuam kev sib txhuam thaum tag nrho cov txheej txheem thauj mus los. Qhov tseem ceeb
Kub-dip galvanized steel yeeb nkab yog tsau rau hauv cov yeeb nkab galvanized hauv cov yeeb nkab galvanized thaum nws ua. Yog li ntawd, txhua qhov chaw sab hauv thiab sab nrauv tuaj yeem raug galvanized, thiab cov yeeb nkab txias galvanized steel feem ntau siv tag nrho cov zinc thaum lub sijhawm tsim khoom. Lub tuab steel phaj yob yog welded thiab welded, thiab tsis muaj kev tiv thaiv ntawm galvanized txheej ntawm welded seam ntawm lub raj.
Yog li ntawd, txhawm rau kom tswj tau hluav taws ntau dua, txhua tus yuav xaiv qhov ruaj ntseg thiab ruaj khov kub-dip galvanized steel yeeb nkab.
