Galvanized Sawb Ntau Lawm Txheej Txheem
1. Pickling thiab decontamination ntawm tag nrho cov yob ntawmstrip steel kom ua tiav qhov kaj thiab huv si.
2. Kub-dip galvanizing: Tom qab pickling, nws yog ntxuav nyob rau hauv lub tank ntawm ammonium chloride los yog zinc chloride aqueous tov los yog tov aqueous tov ntawm ammonium chloride thiab zinc chloride, thiab ces xa mus rau lub nruam annealing rauv thiab ces mus rau hauv lub galvanizing tank rau galvanizing.
3. Lub sawb yog galvanized thiab muab tso rau hauv cia, thiab txheej txheej galvanized tuaj yeem kho raws li cov neeg siv khoom xav tau.
4. Yog tias muaj qhov yuav tsum tau ua rau qhov dav, lubgalvanized steel kaujtuaj yeem ua tiav rau hauv strips.Feem ntau, lub thickness ntawm cov ntaub ntawv toxicity yog 0.12-2mm.
Galvanized steel sawb specification tuaj yeem kho raws li tus neeg yuav tsum tau ua.

Galvanized steel coil / strips yog dav siv rau kev tsim kho, tsev, ru tsev nplooj ntawv, tsheb, kev ua liaj ua teb, khoom siv hauv tsev, cov yeeb nkab vanitation thiab kev lag luam kev lag luam.
Cov khoom siv galvanized steel sawb tuaj yeem muab faib ua cov hlau txias-dov thiab kub-dov hlau.Lub thickness ntawm galvanized sawb nrog txias dov hlau yog 0.12-2 hli, thaum lub thickness ntawm galvanized sawb nrog kub dov steel khoom yog 2-5 hli.Cov qib steel rau txias dov galvanized steel strips yog G550, DX51D + Z, S350, S550, Q195, Q235, SGCC.Cov sawb feem ntau yog hlais los ntawm galvanized steel coils uas dav ntawm 600-1500mm, yog li ntawd cov sawb dav yog muaj.
