1. Cov ntsiab lus sib txawv
Kub-dip galvanizing, tseem hu ua kub-dip galvanizing thiab kub-dip galvanizing, yog ib txoj hauv kev zoo ntawm cov hlau los tiv thaiv corrosion, feem ntau yog siv hauv cov khoom siv hlau hauv ntau qhov kev lag luam. Nws yog txhawm rau txhawm rau txhawm rau txhawm rau xeb tshem tawm cov hlau hauv cov tshuaj zinc molten ntawm li 500 ° C, kom lub ntsej muag ntawm cov hlau ua raws li zinc txheej, thiaj li ua tiav lub hom phiaj ntawm kev tiv thaiv corrosion.
Electrogalvanizing, tseem hu ua txias galvanizing nyob rau hauv kev lag luam, yog cov txheej txheem ntawm kev siv electrolysis los ua ib tug uniform, ntom thiab zoo-bonded hlau los yog alloy deposition txheej nyob rau saum npoo ntawm lub workpiece. Piv nrog rau lwm cov hlau, zinc yog ib qho pheej yig thiab yooj yim plated hlau. Nws yog cov txheej txheem uas tsis tshua muaj nqi los tiv thaiv corrosion thiab dav siv los tiv thaiv steel qhov chaw, tshwj xeeb tshaj yog tiv thaiv atmospheric corrosion, thiab kho kom zoo nkauj.
2. Cov txheej txheem sib txawv
Cov txheej txheem ntws ntawm kub-dip galvanizing: pickling ntawm cov khoom tiav - ntxuav - ntxiv plating tov - ziab - khib plating - txias - tshuaj kho mob - ntxuav - sib tsoo - kub-dip galvanizing tiav.
Electrogalvanizing txheej txheem ntws: tshuaj degreasing - dej kub ntxuav - ntxuav - electrolytic degreasing - dej kub ntxuav - ntxuav - muaj zog corrosion - ntxuav - electrogalvanized hlau alloy - ntxuav - ntxuav - lub teeb - passivation - ntxuav - ziab.
3. Ntau yam khoom siv tes ua
Muaj ntau cov txheej txheem ua rau kub-dip galvanizing. Tom qab lub workpiece yog degreasing, pickling, dipping, ziab, thiab lwm yam, nws tuaj yeem muab tso rau hauv lub molten zinc da dej. Zoo li qee qhov kub-dip yeeb nkab fittings tau ua tiav hauv txoj kev no.
Electrolytic galvanizing yog ua los ntawm cov khoom siv electrolytic. Tom qab degreasing, pickling thiab lwm yam txheej txheem, nws yog immersed nyob rau hauv ib qho kev daws uas muaj zinc ntsev, thiab cov khoom siv electrolytic txuas nrog. Thaum lub sij hawm taw qhia txav ntawm qhov zoo thiab tsis zoo tam sim no, zinc txheej yog tso rau ntawm qhov chaw ua haujlwm. .
4. Qhov txawv txav
Tag nrho cov tsos ntawm kub-dip galvanizing yog me ntsis rougher, uas yuav tsim cov txheej txheem dej kab, dripping qog, thiab lwm yam, tshwj xeeb tshaj yog nyob rau hauv ib kawg ntawm lub workpiece, uas yog silvery dawb tag nrho. Cov txheej txheej ntawm electro-galvanizing yog tus du, feem ntau daj-ntsuab, ntawm chav kawm, kuj muaj cov yeeb yuj, xiav-dawb, dawb nrog lub teeb ntsuab, thiab lwm yam. Tag nrho workpiece yeej tsis tshwm zinc nodules, agglomeration thiab lwm yam tshwm sim.
