Q: Cov txheej txheem galvanizing puas cuam tshuam rau tus nqi ntawm galvanized steel?
A: Electrogalvanizing: Tsim nyog rau nyias txheej txheej (<20μm), high energy consumption (requires direct current), high labor costs, but the initial equipment investment is lower than hot-dip galvanizing.
Hot-dip galvanizing: Suitable for thick coatings (>30μm), Kev siv zog tau ntau yog los ntawm cov cua sov cov kev sib xyaw ua ke, cov cuab yeej siv txij nkawm (tab sis cov cuab yeej tswj khoom siv zinc) yog siab.
Kev sib cais ntawm cov txheej txheem: piv txwv li, zinc-nickel xav tau kev sib ntxiv ntawm cov ntsev tsis zoo, thiab cov khoom siv tau txhim kho corrosion tsis tuaj yeem txo cov tuab yuav tsum tau ua.
Q: Siv cov kev coj ua kom zoo rau galvanized steel?
A: Cov Khoom Siv Hloov Chaw: Siv Zinc-Alloy los hloov cov tsoos galvanizing, uas txo corosion tsis kam los ntawm 2 ~ 3 zaug.
Txheej txheem txhim kho: Siv cov kab ntau lawm los txo cov nqi ua haujlwm, lossis xaiv cov "galvanizing" cov txheej txheem ua ke los txo cov txheej txheem tig.
Kev Tswj Xyuas Kev Tswj Xyuas Kev Tswj Xyuas Kev Ua Haujlwm: phiaj xwm kev tiv thaiv ib puag ncig ua ntej (xws li chromium-free passcling system) kom zam kev hloov cov nqi los ntawm kev hloov pauv txoj cai.
Q: Cov cai tswj hwm yuav cuam tshuam li cas rau cov nqe ntawm cov ntawv galvanized?
A: 1. Cov se thiab kev lag luam Kev Lag Luam: Kev tiv thaiv cov haujlwm ua haujlwm ncaj qha rau cov nqi export.
2. Ib puag ncig cov cai: tus nqi ntawm passivium-dawb passivation yog 8% ~ 12% siab dua li ntawm cov hexavalent chromium passivation, tab sis nws tuaj yeem zam kev nplua.
3. Lub zog tus nqi: rau txhua 10% nce ntxiv hauv cov roj nkev, tus nqi ntawm kub-dip galvaning nce los ntawm zinc melting rhuab yog siab).
Q: Qhov loj npaum li cas yog tus nqi sib txawv?
A: Tus nqi sib txawv ntawm kub-dip galvanizing thiab electroplating yog ntawm 20% thiab 50%, nyob ntawm cov txheej txheej txheej txheej thiab kev tiv thaiv txheej txheem. Kub-DIP galvanizing muaj qhov tseem ceeb them nqi zoo nyob rau hauv tuab txheej txheem tuab thiab ntau ntau lawm, hloov tau yooj yim dua nyob rau hauv nyias txheej txheem thiab cov khoom nyuaj ua.
Q: Yuav ua li cas loj qhov cuam tshuam cov nplai tau them rau tus nqi sib txawv ntawm kub-dip thiab electroplating?
A: Hot-dip Galvanizing muaj cov nqi tseem ceeb hauv kev ntsuas loj (xws li cov txheej txheem siv hluav taws xob ntau tshaj li 10%
Electroplating yog tsuas yog pheej yig dua nyob rau hauv me me batches thiab cov nqi nyias muaj txiaj ntsig los nthuav tawm tom qab cov nplai, thiab lub siab ib puag ncig yog qhov loj dua.
