1. Cov tswv yim sib txawv
Kub-dip galvanizing, tseem hu ua kub-dip galvanizing thiab kub-dip galvanizing, yog ib txoj hauv kev zoo los tiv thaiv xeb hlau, feem ntau yog siv rau hauv cov chaw ua haujlwm hlau hauv ntau yam lag luam. Nws yog kev muab cov hlau uas tau tshem tawm xeb tso rau hauv cov kua zinc uas yaj ntawm li 500 ° C, kom qhov chaw ntawm cov hlau lo rau txheej zinc, kom ua tiav lub hom phiaj ntawm kev tiv thaiv xeb.
Electrogalvanizing, tseem hu ua txias galvanizing hauv kev lag luam, yog cov txheej txheem ntawm kev siv electrolysis los tsim cov hlau lossis alloy deposition txheej sib xws, ntom thiab zoo sib txuas ntawm qhov chaw ntawm cov khoom ua haujlwm. Piv nrog rau lwm cov hlau, zinc yog cov hlau pheej yig thiab yooj yim plated. Nws yog cov txheej txheem tiv thaiv xeb uas tsis muaj nqi thiab siv dav los tiv thaiv cov khoom hlau, tshwj xeeb tshaj yog tiv thaiv kev xeb hauv huab cua, thiab rau kev kho kom zoo nkauj.
2. Cov txheej txheem txawv
Cov txheej txheem ntws ntawm kev kub-dip galvanizing: pickling ntawm cov khoom tiav - ntxuav - ntxiv cov tshuaj plating - ziab - khib plating - txias - kev kho tshuaj - ntxuav - sib tsoo - kub-dip galvanizing tiav.
Cov txheej txheem electrogalvanizing: tshuaj degreasing - dej kub ntxuav - ntxuav - electrolytic degreasing - dej kub ntxuav - ntxuav - corrosion muaj zog - ntxuav - electrogalvanized hlau alloy - ntxuav - ntxuav - ntxuav - lub teeb - passivation - ntxuav - ziab.
3. Kev ua tes ua taw sib txawv
Muaj ntau txoj kev ua cov txheej txheem rau kev kub-dip galvanizing. Tom qab cov khoom ua haujlwm tau tshem cov roj, pickling, dipping, ziab, thiab lwm yam, nws tuaj yeem raug muab tso rau hauv lub dab dej zinc molten. Zoo li qee cov yeeb nkab kub-dip fittings raug ua tiav li no.
Kev siv cov khoom siv electrolytic los ua cov electrolytic galvanizing. Tom qab tshem cov roj, pickling thiab lwm yam txheej txheem, nws raug muab tso rau hauv cov tshuaj uas muaj ntsev zinc, thiab cov khoom siv electrolytic txuas nrog. Thaum lub sijhawm txav mus los ntawm cov hluav taws xob zoo thiab tsis zoo, ib txheej zinc raug tso rau ntawm qhov workpiece.
4. Txawv tsos
Qhov tsos ntawm kev kub-dip galvanizing yog me ntsis rougher, uas yuav tsim cov dej txheej txheem, cov qog dej ntws, thiab lwm yam, tshwj xeeb tshaj yog ntawm ib kawg ntawm cov khoom ua haujlwm, uas yog silvery dawb tag nrho. Lub txheej saum npoo ntawm electro-galvanizing yog du, feem ntau yog daj-ntsuab, ntawm chav kawm, kuj muaj xim, xiav-dawb, dawb nrog lub teeb ntsuab, thiab lwm yam. Tag nrho cov khoom ua haujlwm yeej tsis tshwm sim zinc nodules, agglomeration thiab lwm yam phenomena.
