1.What yog qhov zoo ntawm Galvanized coils piv rau cov xim?
Painting (lossis tshuaj tsuag xim) yog tsim ib qho organic txheej ntawm cov hlau saum npoo, tab sis nws cov} {corrosive lub cav yog qhov tseem ceeb txawv ntawm cov galvanized coils. Qhov zoo ntawm Galvanized coils yog concentrated rau ntev- lub sij hawm ua haujlwm thiab kev puas tsuaj tiv taus.
2.What yog qhov zoo ntawm galvanized chev muab piv rau cua ci txau txhuas?
Thermal txau liag Txhuas cov ntaub ntawv anti - corrosion txheej los ntawm txau txhuas hlau rau hauv cov hlau nto ntawm qhov kub thiab txias. Txawm hais tias nws muaj zog anti - corrosion kev ua tau, nws tsis yog kev lag luam thiab txheej txheem yooj yim li galvanized coils.
Cov nqi ntau lawm: Cov nqi tsim: Galvanized coils yog Mass-} galvanizing (txuas ntxiv cov nqi tswj tau. Thermal txau ntawm txhuas yuav tsum tau cais sandblasting thiab thermal txau ntawm workpiece, uas yog tus txheej txheem nyuaj thiab tus nqi siab (kwv yees li 1.5-2 zaug ntawm galvanizing).
Ua Kev Yooj Yim: Galvanized Coils tuaj yeem sib tuav tau ncaj qha, thiab welded (ov {{{{{{} corrosion txheej tseem zoo dua tom qab kev ua); Cov txheej txheem aluminium ntawm thermal txau yog nkig thiab poob rau thaum ua, yog li nws yuav tsum tau "ua ntej thiab tom qab ntawd ua kom muaj cov khoom sib xyaw)
3.Cov nrog kev kho mob passivation, dab tsi yog qhov zoo ntawm galvanized chev hauv corrosion tsis kam?
Anti {- corrosion txheej thickness thiab lub neej: galvanized coil zinc txheej yog tuab dua), lub neej sab nraum zoov 15 xyoo +; passivation kev kho passivation zaj duab xis passivation fickness tsuas yog 0.1-0.5μm, sab nraum zoov lub neej 1-3 xyoos
Ib puag ncig ib puag ncig: Galvanized coils yog qhov tsim nyog rau sab nraum zoov, noo, thiab lub teeb ntsev tsuag tsuag (xws li thaj chaw ntug hiav txwv); Kev Kho Mob Passivation tsuas yog haum rau sab hauv chaw qhuav (xws li cov hluav taws xob thiab cov khoom siv hluav taws xob me me)
Ua rau cov tshuab puas tsuaj: cov txheej zinc ntawm Galvanized Chev muaj qee qhov kev sib tsoo thiab tsis yooj yim los ntawm kev sib tsoo me me; Cov zaj duab xis passivation yog qhov tsis tshua muaj nyias thiab nkig, thiab yuav poob nrog kev sib txhuam me ntsis.
4.Cov nrog cov hlau stainless, dab tsi yog qhov zoo ntawm galvanized chev?
Cov Khoom Siv Them: Tus nqi tsuas yog 1/3 - 1/4 ntawm 304 stainless hlau. Hauv cov xwm txheej uas "tsim nyog" kev tiv thaiv corrosion yog yuav tsum tau (xws li cov xim tsis muaj roj thiab cov nuj nqis} Lub sijhawm muaj nuj nqis qis heev, thiab nws tus nqi-ua tau zoo tshaj plaws uas tsis muaj hlau.
Tus nqi ua: Nws yog sib xws nrog cov khoom siv hlau ua thiab tsis tas yuav muaj peev ntxiv hauv cov cuab yeej tshwj xeeb. Nws yog qhov tsim nyog tshwj xeeb rau me me thiab nruab nrab - qhov chaw tsim khoom lossis cov teeb meem ntau lawm.
Muaj feem xyuam nrog cov xwm txheej: Tsis tas yuav them tus nqi them rau "- corrosion". Hauv ntau dua 90% ntawm Civil thiab Industrial General Scenmarios, anti- corrosion kev ua tau zoo ntawm Galvanized coils tau ua tiav cov kev xav tau, zam cov khib nyiab raug nqi.
5.Qhov yog tus tseem ceeb sib tw kom zoo ntawm galvanized chev corrosion tsis kam?
"Dual kev tiv thaiv" yog cov kev ntseeg siab dua: nws muab cov yeeb yaj kiab ntawm lub cev (oxide
"Tag nrho {{-}}} scrario hloov tau yooj yim: nws tuaj yeem hloov kho ntau thaj chaw, suav nrog sab nraum zoov, noo, thiab lub teeb ntsev. Nws kuj yog machinable thiab yooj yim rau weld, tshem tawm cov ntawv thov lossis cov txheej txheem kev txwv ntawm cov hlauv txau tshuab thiab hlau.
"Ntev {- tus nqi" yog cov nqi qis dua: tus nqi txij nkawm tau qis dua txhuas, thiab cov khoom siv txij nkawm tsis sib xws tau qis dua cov xim thiab ua haujlwm. Tag nrho lub neej kav tus nqi (thawj zaug + txij nkawm) tsuas yog 50% -70% ntawm cov txheej txheem kev tiv thaiv corrosion.
