1.How corrosion resistant yog galvanized steel sawb?
Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv Anodic: Zinc muaj qhov qis dua electrode peev xwm tshaj li hlau. Thaum cov khoom sib tw hlau yog khawb lossis zinc txheej puas, zinc hydrof thiab zinc hydroced xws li zinc hydround thiab zawv zom cov hlau thiab tiv thaiv cov hlau los ntawm xeb ncaj qha.
Ua ntej ua zaj duab xis ua yeeb yaj kiab: cov txheej zinc ib txwm nyias muaj nyias " Cov yeeb yaj kiab no muaj tus qauv ua tuab thiab muaj zog ua kom zoo nkauj, noo nyob sib cais noo noo, ntsev, thiab txhaws txoj kev corrosion.
2.Yog li cas yog txoj kev tsim thiab ua cov khoom ntawm galvanized steel sawb?
Ductility siab: Seb puas kub {{- dip galvanizing (piv txwv li no), ua rau nws tsis tshua muaj kev lom zem rau zinc tev thiab tawg thaum lub sij hawm ua. Qhov no tso cai rau kev sib nqus nqus (xws li nkhaus saum npoo av ntawm lub cev tsheb ntawm lub cev panels) thiab txuas ntxiv dabtsi yog {} Lub kaum sab xis khoov ntawm cov kab ntawv).
Yooj yim vuam: Galvanized steel sawb, tshwj xeeb, ua ib qho zinc {{}}}} hlau alloy (xws li txheej hlau. Qhov no tiv thaiv cov tseem ceeb tseem ceeb ntawm Zinc evaporation thaum vuam, uas ua rau weld muaj zog mus txog ntawm substrate nws tus kheej. Qhov no ua rau nws haum rau "vuam los ua ke" cov kev xav tau ntawm kev siv siv hauv tsev thiab tsev. Txawm nrog tus qauv kub - dip galvanized stip, weld zoo tuaj yeem tswj cov vuam vuam (xws li txo qhov tam sim no thiab sijhawm). Du nto thiab kev ua tiav kev yooj yim: qhov chaw ntawm cov hluav taws xob ntxiv:} galvanized steel sawb yog tsawg (RA tsawg dua lossis sib npaug yog qhov siab. Nws tuaj yeem ua tau ncaj qha los ntawm kev txau, pleev xim, pasting thiab lwm yam txuas ntxiv yam tsis muaj kev sib deev ntxiv. Txawm hais tias muaj me ntsis zinc paj nyob rau saum npoo ntawm kub- dip galvanized steel sawb, nws tsis cuam tshuam rau cov kev ua xws li kev txiav thiab xuas nrig ntaus thiab xuas nrig ntaus.
3.Qhov yog lub tshuab ua haujlwm muaj zog ntawm Galvanized Steel Sawb?
Kev tsim kho lub zog ua kom haum: Cov khoom siv galvanized stip (xws li Q235 cov khoom siv tensile ntawm 234}}
Siab - lub zog hom nthuav dav: siab li hc340la thiab hc420la thiab lub zog tshiab ntawm 340-780 MPA. Thaum tswj hwm corrosion tsis kam, nws tuaj yeem ua tiav kev los ntawm txo daim ntawv tuab (piv txwv li, txo qhov hnyav ntawm cov txheej txheem txheej txheem tsheb chassis los ntawm 10% -15%).
4.Qhov nqi li cas raug nqi-}} Zoo yog Galvanizing Steel Sawb?
Cov txheej txheem thawj zaug: cov txheej txheem galvanizing (tshwj xeeb tshaj yog kub}}, txuas ntxiv kub- dip galvanizing kab rau steel sawb). Tus nqi rau ib qho chaw ntawm Galvanizing tsuas yog ib qho -}}}}} Cov lus qhia sib tw hlau thiab khoom siv hauv vaj tse).
Tsawg dua cov nqi tswj xyuas tsis tu ncua: vim tias nws cov khoom lag luam siab tiv thaiv, thiab cov neeg tsav tsheb sab nraum zoov, thiab rov ua haujlwm sab nraud, txuas ntxiv rau kev txij nkawm mus txog 5-10 xyoo. Sij hawm dhau los, tus nqi tu tag nrho yog ntau dua 40% qis dua li cov tshuaj hlau thiab xim pleev xim.
5.Qhov yog qhov kev hloov kho ib puag ncig ntawm galvanized steel sawb?
Huab cua Kuj: nws tuaj yeem willagert huab huab los ntawm - 40℃(hauv thaj chaw txias heev) rau 60℃(hauv thaj chaw kub). Cov txheej zinc tsis tawg ntawm qhov kub tsawg thiab tsis yog tev kub (suav nrog allot {
Media tsis kam: Ntxiv rau kom muaj zog acidic (xws li allochloric acid) thiab muaj peev xwm tiv thaiv cov dej nag, thiab cov ntsev me ntsis) Nws tsim nyog rau cov ntawv thov xws li sab nraum zoov kev tsim kho, cov cuab yeej siv tub rog marine, thiab tsheb chassis.
Cov phooj ywg ib puag ncig: cov pov tseg zinc thiab pov tseg ua kua tsim tsim thaum lub galvanizing cov txheej txheem tau rov ua dua tshiab (nrog tus nqi zinc rov qab nce dua 95%). Tsis tas li ntawd, Zinc yog ib puag ncig tus phooj ywg sib xyaw thiab tsis tso tawm cov tebchaw hloov chaw (vocs) zoo li cov xim, cov rooj sib tham tam sim no tau ntau lawm.
