Dacromet Txheej vs. Kub-Dip Galvanizing: Qhov kev tiv thaiv corrosion yog txoj cai rau koj qhov project?
2026-04-30 IB
Corrosion yog tus yeeb ncuab ntsiag to ntawm txhua tus qauv steel. Kev xaiv cov txheej txheem txheej txheej zoo tuaj yeem txhais tau tias qhov sib txawv ntawm lub fastener uas kav ntev txog 10 xyoo thiab ib qho uas ua tsis tau rau 2. Ntawm Fujinrui, peb pab engineers thiab procurement teams thoob ntiaj teb txiav txim siab. Niaj hnub no, peb rhuav tshem ob feem ntau sib piv txheej txheej txheej: Dacromet thiab Kub-dip Galvanizing (HDG).
Lub taub hau-rau-Lub taub hau sib piv
| Feature | Dacromet Txheej | Kub-dip Galvanizing |
| Corrosion Resistance | 800-1,200 xuab moos (ntsev ntsev) | 400-600 xuab moos (ntsev ntsev) |
| Ua haujlwm kub | Txog li 300 ° C | Txog li 250 ° C |
| Hydrogen embrittlement | Tsis muaj kev pheej hmoo (cov txheej txheem ci-dawb) | Risk nrog lub zog muaj zog bolts |
| Txheej Thickness | 4-8 μm (Ultra-thin) | 40-80 μm (thick txheej) |
| Xov Fit | Tsis muaj xov cuam tshuam | Xov re-txiav feem ntau xav tau |
| Environmental Impact | Cr6+-dawb, eco-friendly | Zinc fume emissions |
| Ua tiav Cov tsos | Nyiaj-grey, uniform | Zinc spangle qauv |
| Zoo tshaj rau | High-precision & automotive | Qauv & sab nraum zoov |
Yog vim li cas Ntau Engineers xaiv Dacromet
- Superior Salt Spray Performance: Ua tau zoo HDG los ntawm 2-3x hauv nruab nrab ntsev tshuaj tsuag, ua rau nws zoo tagnrho rau cov dej hiav txwv thiab cov av noo ib puag ncig.
- Tsis muaj Hydrogen Embrittlement: Tshem tawm txoj kev pheej hmoo ntawm kev tsis ua hauj lwm tam sim ntawd ntawm cov fasteners siab zog (chav kawm 10.9 thiab siab dua) - qhov txiaj ntsig kev nyab xeeb tseem ceeb.
- Precision Xov Preservation: Ultra-thin txheej ua kom cov bolts thiab txiv ntseej haum zoo kawg nkaus yam tsis muaj xov tom qab txheej txheej rov ua haujlwm.
- ROHS & ISO ua raws: Ua tau raws li EU ib puag ncig cov qauv. Haum rau tsheb, electronics, thiab export-rhiab kev lag luam.
Thaum twg los xav txog Kub-Dip Galvanizing
HDG tseem yog ib qho kev xaiv zoo rau cov khoom siv loj loj thiab cov phiaj xwm sab nraum zoov uas qhov kev sib hloov corrosion tsis yog qhov kev txhawj xeeb tseem ceeb. Nws ua tau zoo nyob rau hauv ntau daim ntawv thov uas tuab zinc txheej muab kev tiv thaiv txhua yam. Txawm li cas los xij, rau kev ceev nrawm thiab cov ntawv thov kev nyab xeeb-tseem ceeb, Dacromet yog qhov kev daws teeb meem zoo dua.
