Rau galvanized coils, cov nplooj ntawv nyias nyias tau muab tso rau hauv ib lub molten zinc da dej kom ua raws li cov txheej txheem zinc hlau rau ntawm qhov chaw.Nws yog tsuas yog tsim los ntawm cov txheej txheem galvanizing txuas ntxiv, uas yog, cov hlau phaj yog txuas ntxiv rau hauv lub tank plating nrog zinc melted los ua galvanized steel phaj;alloyed galvanized steel phaj.Cov hlau phaj no kuj yog tsim los ntawm kub dip txoj kev, tab sis tam sim ntawd tom qab tawm ntawm lub tank, nws yog rhuab mus txog 500 ℃ los ua ib tug alloy txheej ntawm zinc thiab hlau.Qhov no galvanized kauj muaj cov xim zoo adhesion thiab weldability.
Galvanized txheej txheem
(1) ib txwm spangle txheej
Thaum lub sij hawm ib txwm solidification txheej txheem ntawm zinc txheej, zinc grains loj hlob dawb do thiab tsim ib txheej nrog ib tug pom tseeb spangle zoo.
(2) minimized spangle txheej
Thaum lub sij hawm solidification txheej txheem ntawm zinc txheej, cov zinc nplej yog artificially txwv los ua tus me tshaj plaws spangle txheej.
(3) spangle-dawb spangle-dawb txheej
Cov txheej tau los ntawm kev kho cov tshuaj muaj pes tsawg leeg ntawm cov tshuaj plating tsis pom spangle morphology thiab ib qho chaw sib xws.
(4) zinc-hlau alloy txheej zinc-hlau alloy txheej
Thaum tshav kub kub kev kho mob ntawm cov hlau sawb tom qab dhau los ntawm lub galvanizing da dej los tsim ib tug alloy txheej ntawm zinc thiab hlau thoob plaws hauv lub txheej.Ib txheej uas tuaj yeem pleev xim ncaj qha yam tsis muaj kev kho mob ntxiv dua li kev ntxuav.
(5) txheej txheej
Rau ob sab ntawm galvanized steel ntawv, 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 ua rau ntawm cov ntawv hlau galvanized nrog me me ntawm deformation rau ib lossis ntau lub hom phiaj hauv qab no.
Txhim kho lub ntsej muag zoo nkauj ntawm galvanized steel ntawv lossis tsim nyog rau cov txheej txheej zoo nkauj;ua kom cov khoom tiav tsis pom qhov tshwm sim ntawm cov kab hauv qab (Lydes kab) lossis crease thaum ua kom txo qis ib ntus, thiab lwm yam.
