1.What yog qhov sib txawv ntawm SGCC Galvanized steel thiab dx51d galvanized steel txheem cov qauv?
SGCC: Kev kub kub kub - dip galvanized steel qib teev teev nyob rau hauv tus qauv Japanese (JIS G3302).
DX51D: lub galvanized steel qib teev teev hauv EU qauv (EN 10327). Baosteel lub tswv yim, DC51D, zoo ib yam li DX51d thiab ua raws li Q / BQB40 tus qauv.
2.What yog qhov sib txawv ntawm cov tshuaj lom neeg muaj kuab lom nyob nruab nrab ntawm SGCC Galvanized steel thiab dx51d galvanized steel?
SGCC: Feem ntau siv Spcc txias - rolled steel raws li lub substrate. Nws thawj tiv thaiv yog hlau. Lub zinc txheej yog tsim nyob rau saum npoo los ntawm kub - dip galvanizing txheej txheem. Qhov no zinc txheej yuav muaj cov nqi me me thiab lwm cov ntsiab lus los txhim kho corrosion tsis kam.
DX51D: Feem ntau siv tsawg- cov hlau roj carbon hlau ua lub substrate. Nws lub cim tshuaj lom neeg ua tau raws li qhov yuav tsum tau ua ntawm c% tsawg dua lossis sib npaug los yog sib npaug lossis sib npaug rau 0.02, thiab altens% ntau dua lossis sib npaug rau 0.020.
3.Qhov dab tsi yog qhov sib txawv ntawm kev ua kom cov yam ntxwv ua tau ntawm SGCC thiab DX51D Galvanized steel?
SGCC: Muab cov tshuaj tiv thaiv corrosion zoo heev, pleev xim, muaj peev xwm, thiab cov chaw weldability. Nws zinc txheej yog tus tuab huv si, thiab qhov chaw yog feem ntau ci dawb nrog me zinc spangles, uas ua rau muaj kev ua kom zoo dua.
DX51D: Qhov khoov no thiab tsim cov ntawv qib galvanized muaj kev ua kom muaj kev tsim nyog, tab sis nws cov peev txheej ua haujlwm thiab stamping muaj peev xwm kuj yog qhov nruab nrab. Cov txheej zinc zinc tuab tuaj yeem xaiv raws li cov cai. Cov qib kawm muaj xws li z150, uas muaj ob npaug-}} Sided zinc txheej qhov hnyav ntawm 150g / m².
4.What yog qhov sib txawv ntawm cov chaw thov cov chaw ntawm SGCC thiab DX51D Galvanized steel?
SGCC: feem ntau siv nyob rau hauv cov khoom siv me me thiab lwm cov ntawv sau hlau hlau uas xav tau kev tiv thaiv zoo.
DX51D: feem ntau siv nyob rau hauv kev tsim khoom ntawm txias - Cov hlau, cov qauv tsheb, thiab dav hlau phaj.
5.Qhov twg yog cov kev siv sib txawv ntawm SGCC galvanized steel thiab dx51d galvanized steel nyob rau hauv lub tsheb lag luam luam?
DX51D Galvanized steel: feem ntau siv hauv lub cev lub cev ua haujlwm, xws li cov phuam, cov qhov rooj, thiab pob tw. Qhov no yog vim nws txoj kev muaj txiaj ntsig stampenting zoo, cia nws ua tiav rau hauv cov qauv nyuaj. Nws cov npoo av siab thiab tsis muaj qhov tsis txaus ntseeg pab kom cov tsos zoo thiab muaj qhov tseeb ntawm lub cev panels. Tsis tas li ntawd, DX51D muaj cov tshuaj weldability zoo heev, ua tau raws li qhov xav tau ntawm qhov siab- nplej vuam cov txheej txheem hauv kev tsim khoom lag luam.
SGCC galvanized steel Qhov no yog vim SGCC cov tuab tuab tuab tuab tuab tuab zinc txheej muaj cov txheej txheem corrosion, tab sis cov txheej txheem tuab no tuaj yeem cuam tshuam rau cov ntawv tsim nyog thiab ua tau zoo, thiab tseem muaj nqi.
