China ASTM 653 Prepainted PPGL DX51D DX52D SGCC Galvanized Steel Sheet Coil Manufacturer and Supplier | Ruiyi
Ruva zinc ye dip inopisa Galvanized Coil imhando yetekinoroji yekudzikisa tembiricha yekusimbisa yezingi yemvura (iyo yekusimbisa tembiricha yezingi yakachena i419 ℃) uye kuwedzera nguva yekukura yezinc ruva kristaro nekuburitsa nhamba huru yekristaro nuclei. High kuchena zinc coating (galvanizing layer) haigoni kuumba zinc ruva. Semuenzaniso, kuwedzera tini (<0.5%) kusimba pa198 ℃; kuwedzera cadmium kusimba pa264 ℃; kuwedzera mutobvu kusimba pa317 ℃; kuwedzera antimony (<0.3%) kusimba pa409 ℃; kana kupfapfaidza pamusoro pe zinc coating nemhepo inoyerera kana SO2 gasi kuyerera kunogona kuumba hombe zingi ruva nekukurumidza.
