1.Hho li cas los xaiv lub hauv paus khoom siv hom rau galvanized pob txha?
Feem ntau siv Q235b cov pa roj av feem ntau (tus nqi qis) thiab Q35B qes alloy lub zog hlau (muaj zog siab, haum rau cov chaw tuab si Qhov qis dua cov ntsiab lus carbon thiab impurities (xws li sulphur thiab phosphorus) ntawm cov khoom siv hauv paus, qhov zoo dua rau corrosion tsis kam.
Cov qauv txheej txheem: round raj, xwmfab raj lossis cov raj tshwj xeeb. Qhov loj dua ntawm ntu ntu thiab cov tuab tuab ntawm phab ntsa, qhov muaj zog dua deformation tiv, tab sis qhov nyuaj dua nws yog los npog nrog txheej.
2.Qhov dab tsi yog qhov tseem ceeb tshaj plaws hauv cov txheej txheem galvanizing?
Kub-DIP Galvanizing
Txheej Txheem: Riamive Steel nyob rau hauv Molten Zinc los ua ib qho zinc-hlau alloy txheej + cov ntshiab zinc txheej, nrog tag nrho cov tuab ntawm 20 ~ 80μm.
Cov txiaj ntsig: cov txheej yog ntom thiab muaj lub zog ua kom muaj zog. Cov corrosion tsis kam yog 3 ~ 5 zaug uas ntawm galvanizing galvanizing. Nws yog cov txheej txheem tseem ceeb rau tsev cog khoom hauv tsev cog khoom.
Electrogalvanizing
Txheej Txheem: Cov zinc txheej yog tsim los ntawm cov ntaub ntawv tso nyiaj hauv hluav taws xob, nrog ib qho tuab ntawm 8 ~ 15μm, thiab kev pab cuam passivation feem ntau yuav tsum tau ua.
Daim Ntawv Thov: Tsuas yog tsim nyog rau cov tsev ntsuab luv luv lossis tsis yog tus nqi, thiab tus nqi yog li 1/3 ntawm kub-dip galvanizing.
Zinc-Aluminium-magnesium alloy txheej:
Cov txheej txheem tshiab, txhuas thiab cov magnesium ntxiv rau cov txheej zinc, cov corrosion tsis kam yog 2 ~ 3 zaug uas muaj cov ntug dej hiav txwv loj loj hauv ntug hiav txwv.
3.Qhov yog cov txheej txheej tuab thiab qauv?
Kub-DIP galvanizing yog hais txog GB / T 13912-2020. Cov txheej txheej txheej ntawm cov ntoo hauv tsev cog khoom feem ntau yog ntau dua lossis sib npaug rau 55μm, thiab muaj peev xwm nce rau ntawm thaj chaw uas tsis tshua muaj zog lossis cov khoom ntuj uas muaj acid.
Zinc-Aluminium Txheej yog hais txog ISO 14713. Lub sijhawm ntsev txau tiv taus ntau dua 200% ntawm kub-dip galvanizing tib yam tuab.
4.What cuam tshuam cov av noo thiab hws puas tau muaj lub neej?
Cov av noo nyob rau hauv lub tsev cog khoom muaj ntau dua los yog sib npaug rau 80% puag ncig lub xyoo, thiab dej ua kom haum tau yooj yim tsim nyob rau saum npoo ntawm tus ncej. Yog hais tias lub kua dej tsis yog du (xws li txoj kab nqes ntawm tus ncej tsim yog tsis txaus), cov dej hauv zos yuav ua kom nrawm dua hluav taws xob ntawm cov txheej txheem.
5.Qhov kev cuam tshuam kub thiab UV Rays muaj lifespan?
Nyob rau lub caij ntuj sov, qhov kub nyob sab hauv lub tsev cog khoom tuaj yeem ncav cuag 50 ~ 70 degree, thiab kub nrawm nrawm nrawm ntawm cov txheej zinc. Txawm hais tias ultraviolet rays muaj tsawg ncaj ncaj rau ntawm zinc txheej, lawv yuav ua kom nrawm nrawm ntawm cov ncej (xws li cov foob ntawm cov kab sib txuas), ua rau cov dej corrosion hauv cov khoob.
