Ua ntej tshaj plaws, cov txheej txheem sib txawv:
Txias galvanizing kuj hu uaelectro-galvanizing. Nws siv cov khoom siv electrolysis degrease thiab pickle lub workpiece thiab muab tso rau hauv ib qho kev daws teeb meem ntawm zinc ntsev. Qhov tsis zoo electrode ntawm cov khoom siv electrolysis txuas nrog. Lub phaj zinc muab tso rau sab nraud ntawm lub workpiece thiab txuas nrog cov khoom siv electrolysis. Cov electrode zoo, tig rau lub zog, thiab siv cov kev taw qhia ntawm qhov tam sim no los ntawm qhov zoo electrode mus rau qhov tsis zoo electrode, ib txheej ntawm zinc yuav muab tso rau ntawm lub workpiece.

Kub dip galvanizingtseem hu ua kub dip galvanizing thiab kub dip galvanizing. Nws yog txhawm rau txhawm rau txhawm rau xeb tshem tawm cov hlau rau hauv cov kua zinc melted ntawm qhov kub siab (kwv yees li 500 degree), kom cov zinc txheej txuas rau saum npoo ntawm cov hlau, yog li ua tiav lub hom phiaj ntawm kev tiv thaiv corrosion. Nws yog dav siv nyob rau hauv hlau qauv chaw nyob rau hauv ntau yam industries.

Qhov txawv ntawm qhov tsos:
Cov tsos ntawm electroplated zinc yog tus du thiab ci, thiab cov txheej txheem electroplated siv cov txheej txheem xim passivation kuj tseem yog daj-ntsuab, ua rau nws muaj xim zoo nkauj. Cov txheej txheej electroplated siv cov txheej txheem dawb passivation tshwm bluish dawb los yog dawb nrog lub teeb ntsuab. Cov txheej txheem siv cov txheej txheem dawb passivation tshwm me ntsis xim thaum nws nyob ntawm ib lub kaum ntse ntse nrog lub hnub ci. Cov ces kaum thiab cov npoo ntawm cov workpieces complex yog nquag "hluav taws xob hlawv" thiab ua tsaus, thiab zinc txheej nyob rau hauv cheeb tsam no yog tuab. Nws yog ib qho yooj yim los tsim cov ces kaum tuag tam sim no nyob rau hauv cov ces kaum sab hauv, ua rau undercurrent grey cheeb tsam, thiab zinc txheej nyob rau hauv cov cheeb tsam no yog nyias. Lub workpiece yog dawb ntawm zinc qog, agglomeration thiab lwm yam tshwm sim.
Cov tsos ntawm kub-dip galvanizing yog me ntsis rougher tshaj li ntawm electro-galvanizing, nrog ib tug silvery dawb xim. Cov tsos mob yog nquag ua cov cim dej thiab ob peb drips, tshwj xeeb tshaj yog nyob rau ntawm ib kawg ntawm lub workpiece. Txawm li cas los xij, zinc txheej ntawm kub-dip galvanizing yog kaum ob lub sij hawm thicker dua electro-galvanizing, thiab nws cov kev ua tau zoo los tiv thaiv corrosion yog kaum ob lub sij hawm ntawm electro-galvanizing.
