Kev tsim cov galvanized hlau feem ntau pib nrog siab -zoo qis- carbon steel hlau rods. Cov no raug tshem tawm kom tshem tawm cov nplai thiab cov impurities, ua raws li cov kauj ruam ua ntej xws li ntxuav thiab ziab kom huv si, yog li tsim kom muaj lub hauv paus ruaj khov rau cov hlau txuas txuas ntxiv thiab galvanizing. Tom qab ntau daim duab hla dhau, cov hlau ua tiav qhov ntev yuav tsum tau thiab muaj cov khoom siv kho tshuab zoo heev.
Raws li qhov yuav tsum tau ua, annealing tuaj yeem ua tau los txhim kho cov xaim toughness thiab ductility, txo kev ua haujlwm hardening, thiab txhim kho qhov zoo ntawm cov txheej txheem galvanizing tom ntej. Galvanizing txoj kev feem ntau suav nrog kub-dip galvanizing thiab electro{2}}galvanizing. Kub-dip galvanizing yuav immersing cov hlau nyob rau hauv molten zinc los ua ib tug ntom zinc txheej, uas ua rau superior corrosion kuj. Electro-galvanizing siv cov txheej txheem electrochemical los tso cov zinc txheej, ua kom zoo ib yam, ci tiav rau cov khoom uas xav tau cov khoom zoo.
Tshaj tawm - cov kauj ruam ua haujlwm xws li cua txias, coiling, tshuaj xyuas kom zoo, thiab ntim khoom kuj tseem yuav tsum tau ua. Kev soj ntsuam zoo npog cov tsis xws li zinc txheej thickness, adhesion, tensile lub zog, nto zoo, thiab qhov tseeb qhov tseeb los xyuas kom meej cov khoom ua tau raws li cov qauv tsim nyog thiab daim ntawv thov. Kev tswj hwm nruj ntawm cov txheej txheem tsis zoo ntawm txhua theem tsim khoom tsis yog tsuas yog txhim kho cov galvanized hlau corrosion kuj thiab kev pabcuam lub neej tab sis kuj ua kom cov khoom zoo sib xws, ua tau raws li cov kev xav tau ntawm cov haujlwm xws li kev tsim kho, kev ua liaj ua teb, hluav taws xob, kev sib txuas lus, thiab kev tsim hlau.
