Galvanized coil, ib daim ntawv nyias nyias uas yog dipped nyob rau hauv ib da dej ntawm molten zinc kom adhere ib txheej ntawm zinc rau nws nto. Nws yog tsim los ntawm kev nruam galvanizing, uas yog, coiled steel phaj yog tsis tu ncua dipped nyob rau hauv lub plating tank nrog molten zinc ua galvanized steel phaj; alloyed galvanized steel phaj. Cov vaj huam sib luag steel no kuj yog ua los ntawm cov txheej txheem kub dip, tab sis nws yog rhuab mus txog 500 ℃ tam sim ntawd tom qab tawm hauv lub tank, kom nws tuaj yeem tsim cov yeeb yaj kiab ntawm zinc thiab hlau. Qhov nogalvanized kaujmuaj cov xim zoo adhesion thiab weldability.
(1) Ib txwm spangle txheej spangle txheej
Thaum lub sij hawm ib txwm solidification txheej txheem ntawm zinc txheej, zinc nplej loj hlob dawb do thiab tsim ib txheej nrog pom tseeb spangle morphology.
(2) Minimized spangle txheej
Thaum lub sij hawm solidification txheej txheem ntawm zinc txheej, cov zinc nplej yog artificially txwv los tsim ib spangle txheej me me li sai tau.
(3) Tsis muaj spangle txheej spangle-dawb
Los ntawm kev kho cov tshuaj muaj pes tsawg leeg ntawm cov tshuaj plating, tsis muaj qhov pom pom spangle morphology thiab cov txheej txheej tsis sib xws ntawm qhov chaw.
(4) zinc-hlau alloy txheej zinc-hlau alloy txheej
Kev kho cua sov yog nqa tawm ntawm cov hlau sawb tom qab dhau los ntawm kev da dej galvanizing, kom tag nrho cov txheej txheej txheej txheej txheej ntawm zinc thiab hlau. Cov tsos ntawm cov txheej no yog grey tsaus, tsis muaj xim hlau luster, thiab nws yooj yim rau pulverize thaum lub sij hawm tsim kev kub ntxhov. Tsuas yog kev ntxuav, txheej txheej tuaj yeem pleev xim ncaj qha yam tsis muaj kev kho mob ntxiv.
(5) txheej txheej
Rau ob sab ntawm cov ntawv galvanized steel, txheej txheej nrog zinc txheej sib txawv yuav tsum muaj qhov hnyav.
(6) Smooth daim tawv nqaij dhau
Daim tawv nqaij dhau yog txheej txheem txias dov nrog me me ntawm deformation raugalvanized steel ntawvrau ib lossis ntau lub hom phiaj hauv qab no.
Txhim kho lub ntsej muag ntawm cov ntawv galvanized steel los yog tsim nyog rau cov txheej txheem zoo nkauj; Ib ntus txo qis qhov tshwm sim ntawm cov kab hauv qab (Lüders kab) lossis creases tsim thaum ua tiav cov khoom tiav, thiab lwm yam.
