Hauv lub ntiaj teb kev tsim kho thiab muaj kev lag luam, ob hom khoom lag luam,Pre-galvanized steel rajThiab kub dipped galvanized steel kav, yog siv dav. Txawm hais tias lawv ob leeg yog rau qeb ntawm Galvanized steel khoom, lawv muaj qhov sib txawv ntawm cov kev siv, cov qauv hauv Suav teb, thiab cov qauv khoom lag luam ntau lawm.
1. Kev siv tau
Pre-galvanized steel raj, tseem hu ua ntej - coated galvanized steel raj, feem ntau siv nyob rau hauv ib puag ncig nrog kuj muaj corrosion tsawg yuav tsum tau ua. Piv txwv li, kho kom kho kho kom zoo nkauj sab hauv cov phiaj xwm rau cov khoom siv hluav taws xob. NwsUa ntej - GalvanizedTxheej tuaj yeem muab qee yam kev tiv thaiv kev tiv thaiv kev tiv thaiv me, uas yog txaus rau hauv tsev siv qhov chaw av noo thiab cov tshuaj uas muaj kev sib cav muaj tsawg. Nyob rau hauv rooj tog tsim, tshwj xeeb tshaj yog rau lub moj khaum ntawm qee cov rooj tog zaum - rooj tog zaum,Ua ntej - Galvanized steel leegyog nrov vim lawv tus nqi qis thiab lub teeb hnyav.
Ntawm qhov tod tes,Kub dipped Galvanized Steel KavFeem ntau yog siv nyob rau hauv sab nraum zoov thiab siab - corrosion ib puag ncig. Lawv muaj kev pom zoo ntau yam xws li High - Rive Vaj tse 'Txheej Txheem Vaj Tse, thiab loj - nplai muaj nroj tsuag. Hauv kev muab dej thiab tso dej, tshwj xeeb tshaj yog rau kev xaiv sab nraum zoov, kub thiab muaj peev xwm tiv taus dej, thiab ua kom lawv muaj kev ncaj ncees thiab lub sijhawm ruaj khov.
2. Cov yam ntxwv
Tus yam ntxwv ntawmPre-galvanized steel rajlus dag nyob rau hauv nws kuj nyias galvanized txheej. Qhov no ua rau nws yooj yim rau cov txheej txheem, xws li khoov thiab txiav. Cov txheej txheem ua ntej - Galvanized cov txheej txheem tso cai rau kev tswj kom zoo dua ntawm cov txheej txheej txheej tuab, uas tuaj yeem ua rau muaj kev hnav khaub ncaws zoo dua. Txawm li cas los xij, vim yog cov txheej nyias nyias, nws txoj kev tiv thaiv corrosion yog qhov tsis muaj tsawg piv rau kub - dip galvanized steel kav.
Kub dipped Galvanized Steel Kav, raws li lub npe cuam tshuam, muaj tuab thiab muaj zog galvanized txheej los ntawm cov txheej txheem kub - DIP. Qhov tuab tuab no muab cov tshuaj corrosion zoo heev. Lub zinc txheej tuaj yeem ua raws li kev ua kom muaj kev cawm seej, kev tiv thaiv cov hlau hauv qab cov txheej txheem txawm tias cov nplaim taw mus rau ib qho. Tsis tas li ntawd, kub - dip galvanized steel kav muaj lub zog siab thiab tuaj yeem ris cov khoom siv hnyav, ua rau lawv haum rau ntau yam kev thov siv.
3. Cov Qauv Ntau Lawm nyob hauv Suav teb
Hauv Suav teb, rauPre-galvanized steel raj, cov ntau lawm feem ntau yog ua raws li tus qauv hauv tebchaws GB / t 3091 - 2015 "Welded Steel Kav rau cov khoom siv qis (dej siab ua kua." Tus qauv no cov kev tseev muaj kev yuav tsum tau ua, txoj cai kev ntsuam xyuas, kev tsheb thauj mus los, thauj khoom, thauj khoom hauv Welded Steel rau cov khoom siv hluav taws xob tsawg. Lub pre - galvanizing cov txheej txheem yuav tsum xyuas kom meej tias zinc - txheej ua kom ruaj khov rau cov steel raj kom zoo thiab ua tau raws li cov kev thov sib txawv raws li cov xwm txheej sib txawv.
RauKub dipped Galvanized Steel Kav, cov qauv ua raws li kuj gb / t 3091 - 2015. Txawm li cas los xij, qhov kub - dip galvanizing txheej txheem muaj kev xav tau ntau dua. Cov Zinc - Txheej tuab tuab yog nruj me ntsis tswj hwm kom ntseeg tau ntev - lub sij hawm corrosion tsis kam ntawm cov kav dej. Ib qho ntxiv, cov nplaum thiab cov khoom sib txuam ntawm cov txheej zinc kuj tseem ceeb soj ntsuam kom ntseeg tau tias cov khoom lag luam muaj txiaj ntsig zoo thiab siab - corrosion kev siv.
4. Cov Khoom Siv Khoom Muag Khoom
Pre-galvanized steel rajFeem ntau yog los ntawm ntau yam ntawm sab nraud diameters, xws li 15 hli, nrog phab ntsa thicknesses feem ntau ntawm 1. {} mm. {mm. Cov kev qhia tshwj xeeb no tuaj yeem ua tau raws li cov kev xav tau ntawm cov haujlwm sab nraud sab nraud, xws li me - nplai teeb tsa thiab lub teeb ci ntsa iab qauv.
Kub dipped Galvanized Steel Kavmuaj cov dav dav ntawm cov lus qhia tshwj xeeb. Cov taub ntawm sab nraud tuaj yeem tshwm sim los ntawm 152 {{{{mm} hli lossis loj dua rau qee qhov tshwj xeeb - cov kav dej. Lub Phab Ntsa Thickness tuaj yeem sib txawv ntawm 2.0mm txog 25mm, nyob ntawm cov ntaub ntawv uas muaj tshwj xeeb. Loj dua - Cov kab mob thicker - Walled kub - DIP galvanized steel kav yog feem ntau siv nyob rau hauv dav dav tsim thiab me me - nplai kev muaj peev txheej.
Hauv kev xaus, ob qho tib siPre-galvanized steel rajthiabKub dipped Galvanized Steel KavUa si qhov tseem ceeb hauv cov ntawv thov sib txawv. Nkag siab txog lawv qhov sib txawv tuaj yeem pab cov neeg siv tau txiav txim siab ntau thaum xaiv cov khoom lag luam steel tsim nyog rau lawv cov haujlwm. Seb nws yog ib qho kev kho kom zoo nkauj - kev tsim kho sab hauv lossis cov khoom lag luam zoo yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig zoo thiab ruaj khov ntawm txoj haujlwm.
