Galvanized pipes yog cov kav dej uas muaj txheej tiv thaiv zinc txheej rau cov yeeb nkab txhawm rau tiv thaiv xeb thiab xeb ua ntej. Muaj ntau ntau txoj kev sib txawv rau galvanizing steel yeeb nkab, Kub-Dip Galvanizing thiab Electrogalvanizing yog cov feem ntau siv txoj kev rau steel kav. Kom paub qhov txawv cov Galvanized steel pipeandElectrogalvanized steel yeeb nkab, koj yuav tsum to taub cov txheej txheem ntawm lawv.
Kub-dip Galvanizing
Raws li lub npe implies, txoj kev no yuav dipping lub hauv paus hlau rau hauv lub pas dej ua ke ntawm zinc. Ua ntej, lub hauv paus hlau yuav tsum tau muab ntxuav los ntawm mechanically, chemically, los yog ob qho tib si kom paub tseeb tias ib tug zoo daim ntawv cog lus yuav ua tau ntawm lub hauv paus hlau thiab zinc txheej. Thaum ntxuav, lub hauv paus hlau yog fluxed los tshem tawm cov seem oxides uas yuav nyob twj ywm tom qab kev ntxuav. Lub hauv paus hlau yog ces dipped rau hauv ib da dej ntawm rhuab zinc thiab ib tug metallurgical daim ntawv cog lus yog tsim.
Electro-galvanizing
Electrogralvanizing siv hluav taws xob tam sim no hauv cov tshuaj electrolyte kom hloov zinc ions mus rau hauv cov hlau hauv paus. Qhov no suav nrog hluav taws xob txo qhov zoo ntawm zinc ions rau zinc hlau uas tau muab tso rau ntawm cov khoom zoo. Grain refiners kuj tuaj yeem muab ntxiv uas yuav pab ua kom cov zinc txheej du ntawm cov hlau.
Lub ntsiab sib txawv ntawm Galvanized kav thiab Electrogalvanized steel yeeb nkab:
1.Lub zinc txheej
Lub thickness ntawm kub dip galvanized zinc txheej tuaj yeem ua tiav ntau tshaj 50 microns, qhov siab tshaj plaws tuaj yeem ncav cuag 100 microns.Electro-galvanized zinc txheej feem ntau nyob rau hauv 3 mus rau 5 microns, tshwj xeeb yuav tsum muaj peev xwm ncav cuag 7 mus rau 8 microns.
2. Kev tshwm sim
Kub dip galvanization muaj npub, tsis kaj siab tag.Txawm li cas los xij, Electro-galvanization los nrog zoo kawg nkaus.
3.Siv lub neej
Kub dip galvanized yeeb nkab yog paub tias muaj lub neej siab heev nruab nrab ntawm 20 mus rau 50 xyoo.Tab sis, lectro-galvanization muaj lub neej qis heev, txij li ob peb lub hlis mus rau qee lub xyoo xwb.
4.Cov nqi
Tus nqi yog hais kom nce proportionately nrog ntau dua txheej thickness.li no cov kub dip galvanized yeeb nkab nrog ib txwm coat thickness txog 40% kim tshaj electro-galvanizingpipe.
