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 creation ntawm kub-dip galvanized creation nyob rau hauv nruab nrab ntawm lub xyoo pua 18th yog tsim los ntawm txoj kev loj hlob ntawm thermal hluav taws xob tinage txheej txheem, nrog rau keeb kwm lub sij hawm ntawm 300 xyoo. Txog rau hnub no, kub-dip galvanized tseem yog ib qho kev siv dav thiab kev ua haujlwm zoo hauv kev ntsuas steel.
General welding yeeb nkab:
Feem ntau, welded kav yog siv los thauj tsawg-voltage txaus. Ua los ntawm Q195A, Q215A, Q235A steel. Nws tseem tuaj yeem ua los ntawm lwm cov hlau mos uas yooj yim rau vuam. Cov kav hlau yuav tsum ua cov kev sim xws li dej siab, khoov, thiab flattening, thiab muaj qee yam kev xav tau rau qhov zoo ntawm qhov chaw. Feem ntau qhov kev xa khoom ntev yog 4-10m, thiab tus pas ntsuas ruaj (lossis ntau tus kav) feem ntau yuav tsum tau. Cov kev qhia tshwj xeeb ntawm cov yeeb nkab welded txawv ntawm nominal caliber ( millimeter lossis nti). Lub nominal txoj kab uas hla txawv ntawm qhov tseeb. Cov yeeb nkab welded muaj ob hom: cov kav hlau zoo tib yam thiab cov kav hlau tuab raws li cov phab ntsa tuab.
Galvanized hlau:
Txhawm rau txhim kho corrosion kuj ntawm cov yeeb nkab steel, cov yeeb nkab steel (dub yeeb nkab) yog galvanized. Galvanized steel kav muab faib ua ob hom: kub galvanized thiab electro-steel zinc.
Public welding yeeb nkab:
Cov specifications yog siv nyob rau hauv daim ntawv ntawm seamless kav, thiab welded steel kav uas sawv cev los ntawm lub cheeb txoj kab uas hla * phab ntsa thickness millimeters yog welded nrog cov pa roj carbon zoo tib yam, high-quality carbon steel los yog universal low-alloy steel, los yog welded nrog tropical vuam. Txias txoj kev hu xov tooj. Pej xeem welded kav yog muab faib ua universal zog thiab nyias phab ntsa, zoo tib yam siv raws li structural qhov chaw, xws li kis tau tus mob shafts, los yog conveying kua, thiab nyias phab ntsa los tsim rooj tog, teeb, thiab lwm yam, los xyuas kom meej lub zog thiab dabtsi yog khoov xeem ntawm cov yeeb nkab steel. .
Vim yog tib qho laj thawj, txheej txheej ntawm cov yeeb nkab 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 lub pas dej galvanized thaum nws tsim. Yog li ntawd, tag nrho cov sab hauv thiab sab nrauv tuaj yeem raug galvanized. Cov kav dej txias galvanized steel feem ntau xaiv tag nrho cov zinc thaum ua. 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 txhua leej txhua tus yuav xaiv ib qho kev ruaj ntseg thiab ruaj khov kub-dip galvanized steel yeeb nkab.
