Galvalume-coated steel phajyog ib qho alloy-coated steel phaj dav siv nyob rau hauv ntau qhov chaw xws li cov khoom siv hauv tsev, khoom siv hauv tsev, tsheb, ib puag ncig, machinery, thiab nkoj. Galvalume steel phaj yog them nrog aluminium-zinc alloy ntawm lub phaj steel. Nws yog tsim los ntawm 55% aluminium, 43.4% zinc thiab 1.6% silicon solidified ntawm qhov kub ntawm 600 degree. Nws tag nrho cov qauv yog tsim los ntawm txhuas-hlau-silicon-zinc, tsim ib tug ntom Ib alloy-coated steel phaj nrog quaternary muaju.
Cov qauv tsim nyog: ASTM A792 / M; JIS G3321; BS EN 10215-1995; GB/T 14978-2008
Galvalume-coated steel ntawv muaj ntau yam zoo heev
Corrosion kuj
Kev tiv thaiv corrosion ntawm "galvalume steel kauj"Qhov tseem ceeb yog los ntawm kev tiv thaiv kev ua haujlwm ntawm txhuas. Thaum zinc hnav, txhuas ua cov txheej txheem ntom ntom ntawm aluminium oxide, tiv thaiv corrosion-resistant tshuaj los ntawm ntxiv corroding sab hauv.
kub tsis kam
Aluminium-zinc alloy steel phaj muaj cua sov zoo thiab tuaj yeem tiv taus qhov kub thiab txias ntawm ntau tshaj 300 degrees Celsius. Nws zoo ib yam li qhov kub-kub oxidation tsis kam ntawm aluminized steel daim hlau. Nws yog feem ntau siv hauv cov kav dej chimney, qhov cub, luminaires thiab fluorescent lampshades.
kub reflectivity
Lub tshav kub reflectivity ntawm galvanized steel ntawv yog siab heev, ob zaug ntawm galvanized steel ntawv. Cov neeg feem ntau siv nws ua cov khoom siv hluav taws xob rwb thaiv tsev.
Kev lag luam
Vim tias qhov ceev ntawm 55% AL-Zn yog me dua li ntawm Zn, thaum qhov hnyav yog tib yam thiab cov tuab ntawm cov txheej kub plating yog tib yam, thaj tsam ntawm cov ntawv hlau galvanized yog ntau tshaj 3% loj dua li ntawm galvanized steel ntawv.
Kev ua tau zoo
Kev ua haujlwm ntawm galvalume-coated steel nplooj ntawv zoo ib yam li kub-dip galvanizing, thiab nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm dov, stamping, dabtsi yog khoov thiab lwm yam kev ua.
Corrosion kuj
Qhov kev ntsuam xyuas tau ua nyob rau hauv qhov chaw ntawm kub-dip galvanized steel los xij thiab galvanized steel los xij ntawm tib lub thickness, txheej, thiab kev kho deg. Galvalume muaj kev tiv thaiv corrosion zoo tshaj li kub-dip galvanization, thiab nws cov kev pab cuam lub neej yog 2-6 npaug ntawm cov ntawv zoo tib yam galvanized steel.
Lub teeb pom kev zoo
Lub peev xwm ntawm galvanized zinc los cuam tshuam cov cua sov thiab lub teeb yog ob npaug ntawm cov hlau galvanized, thiab nws qhov kev xav tau ntau dua li {{0}}}.70, uas zoo dua li 0.65 teev los ntawm EPA Energy Star.
Thaum tshav kub kub kuj
Cov khoom siv kub-dip galvanized feem ntau siv qhov kub tsis tshaj 230 degrees. Lawv yuav hloov xim ntawm 250 degrees, thaum cov nplooj ntawv galvanized tuaj yeem siv rau hauv ib puag ncig ntawm 315 degrees yam tsis muaj xim rau lub sijhawm ntev. Tom qab raug 300 degrees rau 120 teev, cov xim hloov ntawm Baosteel lub tshav kub-resistant passivation-kho galvalume-zinc steel daim hlau tau qis dua li ntawm cov phaj txhuas thiab cov phaj aluminized.
Mechanical zog
Cov cuab yeej cuab tam ntawm galvanized steel los xij yog feem ntau cuam tshuam nrog lub zog tawm los, lub zog tensile, thiab elongation. Ordinary DC51D qib 150g/square galvanized steel ntawv feem ntau muaj lub zog tawm los ntawm 140-300mpa, lub zog tensile ntawm 200-330, thiab elongation ntawm 13-25. Lub zog tawm los ntawm DC51D + AZ galvanized 150g / square galvanized steel phaj yog nyob nruab nrab ntawm 230-400mpa, lub zog tensile nyob nruab nrab ntawm 230-550, thiab qhov txuas txuas ntxiv yog nyob nruab nrab ntawm 15-45.
