Dacromet Coating vs. Hot-Dip Galvanizing: Ndi Chitetezo Chotani Chomwe Ndi Choyenera Pa Ntchito Yanu?
2026-04-30
Corrosion ndi mdani chete wa chitsulo chilichonse. Kusankha teknoloji yoyenera yokutira kungatanthauze kusiyana pakati pa chomangira chomwe chimakhala zaka 10 ndi chimodzi chomwe chimalephera mu 2. Ku Fujinrui, timathandizira akatswiri ndi magulu ogula zinthu padziko lonse lapansi kupanga zosankha mwanzeru. Masiku ano, tikugawaniza mitundu iwiri ya zokutira zomwe zimafananizidwa kwambiri: Dacromet ndi Hot-Dip Galvanizing (HDG).
Kuyerekeza kwamutu ndi mutu
| Mbali | Kupaka kwa Dacromet | Hot Dip Galvanizing |
| Kukaniza kwa Corrosion | 800-1,200 hrs (kupopera mchere) | 400-600 hrs (kupopera mchere) |
| Kutentha kwa Ntchito | Kufikira 300 ° C | Kufikira 250 ° C |
| Kuchuluka kwa Hydrogen | Palibe chiopsezo (njira yaulere) | Chiwopsezo chokhala ndi mabawuti amphamvu kwambiri |
| Kupaka makulidwe | 4-8 μm (yoonda kwambiri) | 40-80 μm (wokhuthala) |
| Thread Fit | Palibe kusokoneza ulusi | Kudulanso ulusi kumafunika nthawi zambiri |
| Environmental Impact | Cr6+-free, eco-friendly | Kutulutsa utsi wa zinc |
| Malizani Mawonekedwe | Silver-gray, yunifolomu | Zinc spangle chitsanzo |
| Zabwino Kwambiri | Zolondola kwambiri & zamagalimoto | Zomanga & zakunja |
Chifukwa Chake Mainjiniya Ambiri Amasankha Dacromet
- Kuchita Kwapamwamba Kwambiri Kupopera Mchere: Imaposa HDG ndi 2-3x pamayeso osalowerera amchere, ndikupangitsa kuti ikhale yabwino m'malo am'madzi ndi chinyezi chambiri.
- Palibe Hydrogen Embrittlement: Imathetsa chiopsezo cha kulephera kwadzidzidzi kwa bawuti pazitsulo zolimba kwambiri (kalasi 10.9 ndi pamwambapa) - mwayi wofunikira wotetezeka.
- Precision Thread Preservation: Kupaka kopyapyala kwambiri kumapangitsa kuti ma bolts ndi mtedza zigwirizane bwino popanda kukonzanso ulusi wapambuyo.
- ROHS & ISO Zogwirizana: Imakwaniritsa miyezo ya EU zachilengedwe. Ndiwoyenera misika yamagalimoto, zamagetsi, komanso misika yokhudzidwa ndi zotumiza kunja.
Nthawi Yoyenera Kuganizira Kuwotcha kwa Hot-Dip
HDG ikadali chisankho chotsika mtengo pamabawuti akulu akulu ndi ntchito zapanja zomwe zimawononga dzimbiri sizomwe zimadetsa nkhawa kwambiri. Imapambana muzochulukira zomwe zinc wosanjikiza umapereka chitetezo chamakina. Komabe, pazomangira zolondola komanso zofunikira pachitetezo, Dacromet ndiyo njira yomwe imakonda kwambiri.
