Na U Tšoenyehile ka Rust? Nako ea ho Khetha Dacromet Tataiso e sebetsang ea ho khetha seaparo se nepahetseng sa anti-corrosion bakeng sa li-fasteners tsa hau
2026-05-06
Bothata ba Mafome ke 'Nete
Corrosion e ja liindasteri libilione selemo se seng le se seng. Bakeng sa li-fasteners - mokokotlo o sa bonahaleng oa sebopeho leha e le sefe - ho khetha seaparo se fosahetseng hase feela taba ea litlolo. Ke kotsi ea polokeho. Joale Dacromet e utloahala neng?
Dacromet ke Eng?
Dacromet ke coat ea zinki e sebelisoang ka mokhoa oa dip-spin - ha ho na electroplating, ha ho na hydrogen embrittlement. E fana ka khanyetso ea spray ea letsoai ea 500–1,000+ lihora ha u ntse u boloka filimi e tšesaane, e ts'oanang (4-8 μm).
| Molemo oa bohlokoa: Zero hydrogen embrittlement. Seo se etsa hore Dacromet e be khetho ea ho khetha li-fasteners tse matla haholo (Sehlopha sa 10.9 le holimo) moo polokeho e ke keng ea buisanoa. |
4 Maemo moo Dacromet e Hlōlang
🔩 Li-Fasteners tse Matla a Phahameng
Sehlopha sa 10.9+ sa liboutu se beha kotsing ea hydrogen embrittlement ka electroplating. Dacromet e felisa kotsi ena ka ho feletseng.
🌊 Tikoloho ea Metsi a Letsoai le Mongobo
Meaho ea mabōpo a leoatle, lisebelisoa tsa metsing, li-platform tsa lebōpong la leoatle - Dacromet e fana ka khanyetso ea 500-1,000h ea letsoai la letsoai.
🚗 Likopo tsa likoloi le tsa EV
Li-OEM li hlakisa Dacromet bakeng sa chassis, brake, le likarolo tsa meralo. E kopana le litekanyetso tsa indasteri ea likoloi.
📐 Likarolo Tse Tight Mamello
Ho roala ha mosesaane (4-8 μm) ho bolela hore ha ho na tšitiso ea khoele. Ha ho na ho tlanya hape, ha ho na mathata a kopano.
Kamoo e Bapisang Kateng
| Thepa | Dacromet | Hot-Dip Galv. | E-Zinc Plating |
| Sefafatsi sa letsoai (h) | 500–1,000+ | 200–600 | 24–96 |
| Hydrogen Embrittlement | Ha ho letho | Kotsi e teng | Kotsi e phahameng |
| Botenya ba ho roala | 4–8 μm | 40-80 μm | 5–15 μm |
| Khoele Fit | E kgabane | E futsanehile (e teteaneng) | E ntle |
| Ho Baka Ho Hlokahala | Che | Che | Ho joalo (4–8h) |
| Boemo ba litšenyehelo | Mahareng | Tlase | Tlase |
Ha Dacromet e ka se be Molemo ka ho Fetisisa
Dacromet ha se karabo bakeng sa boemo bo bong le bo bong. Haeba o hloka qetello ea mokhabiso, hot-dip galvanizing e fana ka boipiletso bo botle ba pono. Bakeng sa libaka tse ka hare, tse nang le kutu e tlaase, ho roala zinki ho ka ba ho lekaneng - le ho theko e tlaase. 'Me haeba ho apara ka mokhoa o feteletseng ke ts'okelo e ka sehloohong (eseng kutu), chrome e thata kapa liaparo tsa ceramic li tšoanela ho shebahala.
The Bottom Line
Haeba projeke ea hau e kenyelletsa li-fasteners tse matla haholo, ho pepeseha ha metsi a letsoai, lintlha tsa koloi, kapa mamello e tiileng ea likhoele - Dacromet ha se khetho feela. Ke khetho e nepahetseng.
