1.What yog qhov zoo ntawm Q235B galvanized ntawv piv rau cov ntawv steel zoo tib yam?
Tsis tshua muaj corrosion -} illive: Lub zinc ib puag ncig cua (cia li 10 {{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{}
Kev Txij Nkawm Me: Tsis muaj xim ntxiv lossis anti - corrosion txheej yog qhov yuav tsum tau, ua kom yooj yim tupoging tu.
Luam Ntawv: Kev tso cai ntawm Q235b ntawm Q235b Steel, tso cai rau dabtsi yog khoov, stamping, thiab txiav (tsuas yog xav tau kev tiv thaiv zinc).
Cov Txheej Txheem Elegant: Qhov kub - dip galvanized txheej yog tus txias galvanized {1} Nws haum rau kev thov kom tsawg kawg nkaus.
2.Qhov dab tsi yog qhov tsis zoo ntawm Q235B galvanized ntawv piv rau cov ntawv steel zoo tib yam?
Cov nqi siab dua: Galvanizing cov txheej txheem nce raw cov txheej txheem raw dua, thiab cov txheej txheem complex ua rau cov ntawv tuab ua rau muaj tus nqi nce ntau.
Vuam yog qhov nyuaj me ntsis: Cov kab zinc yooj yim ua cov rods / xov hlau tshwj xeeb, lossis ua ntej {{{{{} yuav cuam tshuam weld zoo.
Lub zinc txheej yog yooj yim puas: ua pob thiab khawb thaum lub sij hawm thauj mus los thiab kho cov xeb uas muaj xeb (kho kom nrawm nroos ib ce (}}} daim ntawv thov ntawm zinc muab tshuaj txhuam).
Tsawg qhov siab siab - kub kev ua tau zoo: lub zinc txheej muaj qhov taw tes tsawg (kwv yees li 419 degree). Kev ntev raug rau qhov kub tshaj 300 qib tuaj yeem ua rau oxidation thiab detachment ntawm zinc txheej, yog li poob nws txoj kev tiv thaiv corrosion.
3.Qhov dab tsi yog qhov zoo ntawm Q235b Hlau Hlau (Ungalvanized)?
Tus nqi qis dua: Tshem tawm cov txheej txheem galvanizing, cov khoom siv raw cov khoom siv yog 10% -30% qis dua cov hlau galvanized (qhov sib txawv hloov nrog zinc tus nqi).
Tsis tas yuav muaj kev cuam tshuam saum npoo av: Tsis muaj zinc txheej thaum cov duab txuas ntxiv), ua kom haum rau cov txheej txheem tom qab cov tshuaj txau thiab hluav taws xob.
Ntau qhov yoog tuab tuab: Cov ntawv steel zoo tib yam muaj cov txheej txheem dav dav (los ntawm 0.} Tus txheej txheem tuab
4.Qhov dab tsi yog qhov tsis zoo ntawm Q235b Hlau Hlau (Ungalvanized)?
Kev tsis zoo corrosion resistance: cov khoom siv hauv paus yog ncaj qha rau cov dej noo, sab nraud, lossis hauv plua plav / noo noo} {} {nplua nuj ib puag ncig thiab muaj kev xeb. Kev pleev xim yog qhov yuav tsum tau nyob hauv ib lub sijhawm luv (1-3 xyoos) los tiv thaiv cov qauv zog.
Ntev - sij hawm tu yog cumbersome: tsis tu ncua xeb, tshwj xeeb yog nyob rau hauv kev cob qhia tshuaj lom neeg (xws li cov chaw nres tsheb tshuaj lom neeg thiab cov chaw nres tsheb hauv qab). Kev saib xyuas cov nqi nce nrog lub hnub nyoog.
Luv Service Lub Neej: Tsis muaj kev pab cuam lub neej zoo:- corrosion kev kho, cov kev pabcuam lub neej ntawm cov ntawv steel hlau tsuas yog 1 / 3-1 / 2 tias cov ntawv galvanized. (Piv txwv li, rau sab nraum zoov cov qauv, daim ntawv hlau zoo tib yam nkaus yuav xeb kom loj dua tom qab 5 xyoo, thaum Galvanized daim ntawv yuav nyob ntev dua 15 xyoos.)
5.Qhov yog cov mob corrosion tsis kam ntawm Q235B Galvanized ntawv thiab cov hlau steel zoo?
Cov ntawv hlau zoo tib yam: Cov khoom siv hauv paus yog ib cov hlau - carbon alloy. Thaum nthuav tawm huab cua, cov hlau undergoes elecegoes corrosion nrog oxygen thiab dej, kev nplua cov hlau oxide (xeb xoob (xeb). Qhov no xeb tsis tuaj yeem tiv thaiv kev xeb ntxiv los ntawm thiab yuav txuas ntxiv mus rau sab hauv. Piv txwv li, ntawm qhov tsis pom zoo sab nraum zoov daim ntawv, pom tias xeb yuav ncav cuag ib qho tsis pub dhau 0.1mm nyob rau hauv 1-2 xyoos hauv 1-2 xyoos, kev cuam tshuam cov khoom muaj peev xwm tshaj tawm.
Q235B Galvanized Sheet: Nws tso siab rau cov haujlwm ntawm "Zinc fij rau Anodic kev tiv thaiv" thiab "kev sib cais":
{- kev cais lub cev: zinc txheej nruj me ntsis npog cov khoom siv hauv paus, tiv thaiv dej thiab oxygen los ntawm mus txog ntawm cov hlau.
{{0- Kev Tiv Thaiv Anodic Anodic: Yog tias Zinc Electrode qhov peev xwm (tiv thaiv cov hlau cov khoom siv los ntawm kev xeb), yog li tsim "Cathodic kev tiv thaiv."
Raws li qhov tshwm sim, cov ntawv galvanized tuaj yeem nyob twj ywm rau lub sijhawm ntev txawm tias nyob rau hauv qab zib los nag lossis hauv qab zib (uas tsis yog corrosive). It only corrodes slowly under extreme conditions (such as strong acids and high-concentration salt spray).
