Galvanized steel kaujyog los tiv thaiv corrosion ntawm daim ntawv hlau thiab ua kom nws lub neej ua haujlwm ntev.Qhov saum npoo ntawm cov ntawv hlau yog coated nrog ib txheej ntawm hlau zinc.Hom galvanized steel ntawv / kauj yog hu ua galvanized ntawv / coil.Lub nyias steel kauj yog immersed nyob rau hauv lub molten zinc tank, thiaj li hais tias ib txheej ntawm zinc yog adhered rau saum npoo.Tam sim no, nws yog tsim los ntawm cov txheej txheem txuas ntxiv galvanizing, uas yog, txuas ntxiv mus rau ntawm cov ntawv hlau coiled hauv lub tank galvanized nrog molten zinc los ua galvanized steel ntawv / coil.
Yuav ua li cas los laij cov galvanized steel kauj qhov hnyav?Qhov hnyav xam mis ntawm galvanized sheet coil:
M (kg / m) = 7.85 * dav (m) * tuab (mm) * 1.03
Piv txwv li: tuab 0.4 * 1200 dav: hnyav (kg / m) = 7.85 * 1.2 * 0.4 * 1.03 = 3.88kg / m
Lub galvanized coil yuav tsum muaj qhov zoo nkauj, thiab yuav tsum tsis muaj qhov tsis zoo uas ua rau muaj kev phom sij rau kev siv cov khoom, xws li tsis muaj plating, qhov, tawg, scum, ntau plating thickness, khawb, chromic acid av, dawb xeb, thiab lwm yam. . Cov qauv txawv teb chaws tsis paub meej txog cov tsos mob tshwj xeeb.Qee qhov tsis xws luag yuav tsum tau teev nyob rau hauv daim ntawv cog lus thaum xaj.
