Kub Dip Galvanized

Dab tsi yog kub dip galvanizing?

1. Kub dip galvanizing yog ib daim ntawv ntawm galvanizing. Nws yog cov txheej txheem ntawm txheej hlau nrog zinc, uas tsim ib qho alloy nrog rau saum npoo ntawm lub hauv paus hlau thaum cov hlau yog immersed nyob rau hauv ib da dej ntawm molten zinc ntawm qhov kub ntawm kwv yees li 450 degree (842 degree F). Thaum raug rau cov huab cua, cov zinc ntshiab (Zn) reacts nrog oxygen (O2) los tsim zinc oxide (ZnO), uas ntxiv reacts nrog carbon dioxide (CO2) los ua zinc carbonate (ZnCO3), uas yog ib qho kev ua ib qho grey tsaus, cov ntaub ntawv muaj zog heev uas nyob rau hauv ntau rooj plaub tiv thaiv cov hlau hauv qab los ntawm corrosion ntxiv.Galvanized hlauyog dav siv nyob rau hauv daim ntawv thov yuav tsum tau corrosion kuj tsis muaj nqi ntawm stainless hlau thiab yog xam superior nyob rau hauv cov nqe lus ntawm tus nqi thiab lub neej voj voog. Nws tuaj yeem raug txheeb xyuas los ntawm cov qauv crystalline ntawm nws qhov chaw, feem ntau hu ua "sequins."

2.Coil txheej yog ib qho ntawm cov ntawv thov tseem ceeb rau kub dipgalvanized txias dov steelthiab zinc. Kev tu kom zoo thiab kho ua ntej yog qhov tseem ceeb rau txoj haujlwm no. Ua ntej cov kauj ruam pretreatment, cov khoom yog ntxuav thiab ua kom lub ntsej muag. Cov tshuaj ntxuav BONDERITE tshiab muaj los txhim kho qhov adhesion, thiab lawv ua haujlwm sib koom ua ke nrog kev kho ua ntej kom tsis txhob muaj xim bubbling.

Cov tom ntej yaug-dawb ua ntej kev kho mob yog txhim khu kev qha thiab yooj yim los tswj. BONDERITE cov kev daws teeb meem hloov cov xim hlau rau hauv cov txheej txheem tsis yog xim hlau tsim nyog rau kev ua kom adhesion thiab tiv thaiv corrosion. Tsis muaj dej khib nyiab yog tsim los ntawm qib pretreatment. Nyob rau hauv txoj kev no, Henkel's pretreatments pab kom peb cov neeg siv khoom ua kom muaj txiaj ntsig zoo rau kev ruaj khov thaum ua kom cov txheej txheem ua tau zoo thiab txo cov nqi.
