Dab tsi yog cov khoom siv ntawmS350 GDKub dip galvanized hlau?
S350GD kub-dip galvanized steel kauj:
S: Cov qauv hlau
350: Yam tsawg kawg nkaus yield zog 350 MPa (siab dua li qub DX51D)
GD: Galvanized los ntawm Kub-Dip txheej txheem
+Z: Kub-dip galvanized txheej (Zinc Txheej), xws li Z275 txhais tau tias tag nrho qhov hnyav ntawm ob - sab zinc txheej yog 275g / m².
Mechanical zog:
Yield zog: Ntau tshaj los yog sib npaug rau 350 MPa
Tensile zog: 420-510 MPa
Elongation: Ntau dua lossis sib npaug li 18% (zoo rau kev khoov txias)
Anti-kev ua haujlwm corrosion:
Cov txheej zinc muab 10-30 xyoo ntawm kev tiv thaiv corrosion (nyob ntawm ib puag ncig), thiab txhuas zinc plating (AZ150) yog xaiv tau rau qhov chaw hnyav.
S350GD + Z steel sib npaug li cas?
European tus qauv EN 10346 S350GD sib haum rau:
American standard A653 SS50 (lub zog 345MPa)
Lub teb chaws tus qauv GB / T 2518 S350GD (tib yam tsis muaj)
Nyiv tus qauv JIS SGHC (yuav tsum tau kuaj lub zog)
Dab tsi yog hom S350GD steel zinc txheej?
Ntshiab zinc txheej (Z):
Zinc kua muaj pes tsawg leeg: 99.95% ntshiab zinc + 0.03% txhuas
Txheej txheej: η theem (ntshiab zinc txheej) + ζ theem (FeZn13)
Aluminium zinc txheej (AZ):
Zinc kua muaj pes tsawg leeg: 55%Al+43.5%Zn+1.5%Si
Corrosion kuj yog 2-4 npaug ntawm cov zinc ntshiab
Dab tsi yog qhov txawv ntawm S350GD steel thiab stainless hlau?
S350GD + Z yog galvanized carbon hlau. Tsis zoo li cov hlau tsis muaj steel (xws li 304/316), nws txoj kev tiv thaiv corrosion cia siab rau kev tiv thaiv kev txi ntawm zinc txheej es tsis yog chromium passivation zaj duab xis.
Daim ntawv thov ntawm S350GD + Z steel hauv kev tsim kho
(1) Load-cov kabmob qauv
Cov nroj tsuag muaj: ru tsev trusses, purlins, txhawb nqa beams
Warehouse/logistics center: loj rhawv, steel qauv ncej
Cov txuas txuas / cov hla: theem nrab load-cov kabmob (yuav tsum tau ua ke nrog kev tiv thaiv-corrosion tsim)
(2) Qhov system kaw
Hlau ru tsev / phab ntsa: ua ke nrog cov ntawv profiled (xws li cov ntawv corrugated, cov ntawv trapezoidal)
Cov qhov cua nkag: huab cua tiv taus zoo dua li cov khaub thuas zoo tib yam -rolled steel
(3) Cov xwm txheej tshwj xeeb
Cov ntug dej hiav txwv / cov av noo siab: S350GD + Z275 lossis S350GD + AZ150 raug pom zoo
Chemical Zone: PVDF txheej tuaj yeem muab ntxiv los txhim kho cov tshuaj tiv thaiv corrosion
