Q: Dab tsi yog cov khoom sib xws ntawm cov chaw uas tsis zoo ntawm cov hlau galvanized uas tuaj yeem kho tau?
A: {{1.} ploj lawm plating / nthuav dav hlau (ib nrab ntawm zinc plating)
{{02. Zinc Nodules / zinc Slag Adhesion (saum npoo tsa cov nplais)
{{03. xim dawb (powderery dawb (dawb powdery corrosion nyob rau saum npoo)
4. av / roj nyob rau saum npoo (roj, passivation kua cov khoom seem, thiab lwm yam})
5.} Txiaj / khawb (tsis muaj nthuav tawm afostrate)
{{06. Tsis txaus plating thickness (ib nrab lossis tag nrho cov nyias)
Q: Dab tsi yog cov kev tsis xws luag ntawm galvanized steel surfaces tsis tuaj yeem kho lossis yuav tsum tau kho nrog kev ceev faj?
A: Thaj chaw loj ntawm cov hlau tsis raug / cov hlau raug
Plating peeling / flaking
Kev loj heev ntawm qhov chaw siab / ntxeem tau
Plating teeb meem tshwm sim los ntawm substrate tsis xws luag
Missed plating tshwm sim los ntawm weld tsis xws luag
Q: Yuav ua li cas kho cov plating plating / spreed hlau (ib nrab ntawm zinc plating)?
A: Zinc-nplua nuj Xim Kho: Siv khaub ncaws khaub thuas epoxy-nplua nuj los ntawm qhov tsis muaj kev tiv thaiv zoo dua lossis sib npaug ntawm cov qauv zincy)
Kub-Tshuaj Zinc: Siv Arc txau los yog nplaim taws ntawm cov txheej xim zawv zawg, haum rau ib puag ncig sab nraum zoov, haum rau ib puag ncig sab nraum zoov lossis ib puag ncig ntawm sab nraum zoov.
Vuam galvanizing: rau cov ntsiab lus tsis tshua muaj neeg nyob (xws li lub taub<5mm), you can first use zinc welding rods for repair welding, then grind it flat and apply passivation liquid.
Q: Yuav ua li cas yuav tsum zinc no / zinc slag symmonment (tsa ceg rau saum npoo) yuav kho?
A: Kev sib tsoo tshuab: siv cov ntaub ntawv zoo nkauj, cov ntaub ntawv lossis cov hluav taws xob sib tsoo kom tsis txhob sib tsoo nrog cov khoom siv thicker {}}
Tshuaj Txhuam Hniav Tsis Zoo: Thov Dilute Hydrochloric acid (5% ~ 10%} Tom qab lub sij hawm cov tshuaj tiv thaiv huv thiab qhuav, tom qab ntawd thov passivation kua {}}
Cua sov thiab muag kom zoo: rau cov cua sov cua sov loj, ua kom ze rau cov cuab yeej siv zinc (419℃nrog cov cuab yeej, thiab polished du thiab polished du tom qab txias.
Q: Yuav ua li cas kho cov xeb dawb ntawm cov hlau galvanized?
A: Siv cov ntaub mos mos muag: Siv cov ntaub so mos lossis luam tawm cov txheej dawb (tsis txhob ntxuav cov txheej dawb nrog cov hlau xaim nrog lub ethanol lossis acetone .
Kev kho tshuaj lom neeg: so dawb muaj xeb: so nrog ib tus 3% ~ 5 feeb, tom qab ntawd yaug thiab qhuav noj mov ua kua .
Dig Dias Dawb: Thawj qhov nruab nrab cov khoom xeb nrog 10% citric acid daws, yaug thiab qhuav, tom qab ntawd siv zinc-nplua nuj xim lossis rov ua dua.
