Q: Ua ntej Electrogalvanizing, ib qib pretreatment yog qhov yuav tsum tau, uas yuav cuam tshuam degrefole degreat . Koj muaj ntau yam li cas?

A: Tshuaj huv degrasing: Siv cov tshuaj alkaline (xws li sodium carbonate, so kom tshem cov tsiaj thiab cov roj ntxhia los ntawm emulsification .
Kev siv tshuab hluav taws xob rau hluav taws xob: lub workpiece yog siv los ua anode lossis catread, tab sis tej zaum yuav ua rau muaj cov roj ntsha electrolyte, tab sis tuaj yeem corroge ntawm substrate) .
Ultrasonic degreat: Siv cov tshuaj lom neeg tshuaj xyuas kom ua kom nrawm dua qhov roj av ntawm cov roj ntau heev {}}

Electro galvanized sheet

 

Q: Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov kev daws teeb meem?

A: Maint ntsev: muab zinc ions, hom ntau yam suav nrog:
Cyanide zinc plating: Zinc Cyanide + Sodium Cyanide, cov txheej txheej zoo tab sis muaj maj phased (maj phased tawm).
Cyanide-dawb zinc plating: chloride zinc plating: zinc chloride: tanassium chloride, cov txheej txheem yooj yim, haum rau cov txheej ci txheej.
Sulfate zinc plating: zinc sulfate + sodium sulfate, tus nqi qis, haum rau tuab zinc plating lossis hlau.
Zincate zinc plating: Sodium hydroxide, ib puag ncig phooj ywg tab sis tsis zoo dispersion muaj peev xwm {}}

 

Electro galvanized coil

Q: Vim li cas thiaj li ua tiav cov txheej txheem tseem ceeb ntawm electrogalvanizing?

A: Lub hom phiaj ntawm passivation yog tsim ib txheej passivation zaj duab xis nyob rau saum npoo

 

Electro galvanized coil

Q: Muaj pes tsawg hom passivation yog muaj?

A: Hexavalent Chromium Passivation: Cov txheej txheem ua ib txwm muaj (xws li xiav-dawb passivation,, tab sis hexavalent chromium yog tshuaj lom thiab tsuas yog siv nyob rau hauv cov xwm txheej tshwj xeeb.
Trunticent Chromium Passivation: Ib puag ncig cov txheej txheem, corrosion cov txheej txheem, corrosion cov kev sib ze ze rau hexavalent chromium, xws li xiav-dawb, dub) {1}.
Kev Kho Mob Chromium-Dawb Passion: Silane Kev Kho, Titanate kev kho, haum rau kev tiv thaiv ib puag ncig ib puag ncig xav tau {}}

 

 

Q: Yuav sim ntsuas qhov zoo tom qab electrogalvanizing?

A: {{{1.} yuav tsum tau sib xyaw, tsis muaj kev plaw, hlawv, hlawv thiab lwm yam tsis xws luag.
2.} Thickness nrhiav tau: Sib nqus Thermness
Coulometric Struction: Ntsuas cov tuab ntawm cov txheej txheem electrolytic stripping ntawm txheej, nrog qhov muaj tseeb.
{{03. Cov qauv kev sim: Kev sib tsoo hom, txiav txheej txheem, saib seb puas poob nthab poob tawm ntawm.
{{04. Corrosion Kuj Xeem Kev Xeem: Kev ntsuas ntsev, xav tau lub sijhawm ntsev kom tau raws li tus qauv (xws li 72 teev yam tsis muaj xeb dawb).
