Q: Cov ntsiab lus tseem ceeb cuam tshuam rau cov corrosion tsis kam ntawm electrogalvanized steel?
A: {{1. txheej tuab tuab
Cov Txheej Txheem Tiv Thaiv Kev Tiv Thaiv: Cov txheej txheem zinc raws li "kev tiv thaiv tus hlau-oxidation (oving zno-}}
2. cov txheej txheem passivation
Tsis muaj passivation (liab qab zinc txheej): tsis zoo corrosion tsis kam, yooj yim rau cov xim dawb (zinc oxide), tsuas yog siv rau kev tiv thaiv ib ntus {}}
3.}} siv ib puag ncig
Nruab nrab nruab nrab ib puag ncig (xws li thaj chaw nyob hauv tsev, cov txheej qhuav): cov txheej txheej tsis muaj peev xwm tiv thaiv {{1} .
Q: Dab tsi yog cov tuab tuab cov qauv rau electrogalvanizing?
A: Zoo nkauj Galvanizing: 3-8 μm, ntsev txau tiv thaiv kev xeem yog li 24-72 teev (xws li cov khoom vaj huam sib luag);
Kev tiv thaiv galvanizing: 8-25 μm, tshuaj tsuag dej tsis kam tuaj yeem ncav cuag 100-1000 teev (xws li cov tsheb nqaj hlau xav tau ntau tshaj 200 teev) {7}.
Q: Ib qho chaw tshwj xeeb ib puag ncig cuam tshuam rau corrosion tsis kam ntawm electrogalvanized steel?
A: Kev tshuaj tsuag ntsev (Dej hiav txwv, cov txheej txheem daus uas melten ntau dua lossis sib npaug ua kom muaj zog ntau dua lossis sib npaug li 500 teev); ◦ Acidic/alkaline environment (industrial areas, agricultural areas): Sulfur dioxide (SO₂), ammonia (NH₃), etc. accelerate corrosion, requiring an increased coating thickness or a closed coating.
Q: Dab tsi yog cov txiaj ntsig ntawm passivation cov txheej txheem ntawm corrosion resistance ntawm electrogalvanized khoom?
A: Tsis muaj passive (liab qab zinc txheej): tsis zoo corrosion tsis kam, yooj yim rau cov xim dawb (zinc oxide), tsuas yog siv rau kev tiv thaiv ib ntus {}}
Chromate passivation (ib txwm txheej txheem, maj mam tshem tawm):
Hexavalent chromium passivation: Ua ib zaj duab xis passivation muaj cr⁶⁺, uas tuaj yeem tiv thaiv cov kev cai ntsev rau}? .
Chromium-dawb / Tsawg-Chromium Passivation (cov txheej txheem tseem ceeb):
TrunticTent Chromium Passivation: Ua ib zaj duab xis cr³nite, uas tuaj yeem tiv thaiv cov ntsev tsuag kom muaj kev tiv thaiv ib puag ncig;
Cov khoom lag luam ruaj khov / Organic ntawm cov microses ntawm zinc txheej los ntawm cov tshuaj pleev xim molecular, thiab yog qhov tsim nyog rau cov kev tiv thaiv ntsev rau kev tiv thaiv siab.
Q: Dab tsi yog corrosion tsis kam ua yeeb yam hauv cov ntawv teev npe raug?
A: {1. tsheb tsheb bolts:
Ntsev txau tshuaj tiv thaiv 200-500 teev, kev pabcuam lub neej ntawm txog 5-8 xyoo hauv nroog loj hauv nroog {}}
{{02. Cov khaub ncaws txuas ntxiv: Kev pab cuam sab hauv tsev: 8-10 xyoo nyob rau hauv thaj chaw ntug hiav txwv (ntau tshaj 10 xyoo) {{8}
