Tuam Tshoj ASTM 653 Prepainted PPGL DX51D DX52D SGCC Galvanized Steel Sheet Chev Chaw tsim tshuaj paus thiab tsum | Ruiyi
Zinc paj ntawm kub poob Galvanized Coil yog ib hom kev siv tshuab los txo qhov kub thiab txias ntawm cov kua zinc (lub solidification kub ntawm cov zinc ntshiab yog 419 ℃) thiab ncua lub sij hawm loj hlob ntawm zinc paj siv lead ua los ntawm kev tsim ib tug loj tus naj npawb ntawm crystal nuclei. High purity zinc txheej (galvanizing txheej) tsis tuaj yeem tsim zinc paj. Piv txwv li, ntxiv tin (< 0.5%) kom solidify ntawm 198 ℃; ntxiv cadmium rau solidify ntawm 264 ℃; ntxiv cov hmoov lead kom solidify ntawm 317 ℃; ntxiv antimony (<0.3%) kom solidify ntawm 409 ℃; los yog txau rau saum npoo ntawm zinc txheej nrog cov dej ntws los yog SO2 roj ntws tuaj yeem tsim cov paj zinc loj kom sai li sai tau.
