Thaum twg Yuav Tsum Tau Anchor Bolts Siv Dacromet Txheej?
2026-06-15 IB
Daim ntawv qhia tswv yim rau xaiv Dacromet-coated foundation bolts, stud bolts, hex bolts, thiab fastener assemblies rau corrosive thiab high-thov kev lag luam ib puag ncig.
DACROMET txheej yog dab tsi?
Dacromet (tseem sau Geomet lossis Dacrotized) yog dej-raws li, chromium-dawb zinc-flake txheej siv rau cov pa roj carbon steel fasteners - nrog rau cov ntsia hlau thauj tog rau nkoj, lub hauv paus bolts, stud bolts, hex bolts, flange bolts, ceev, thiab washers. Lub nyias, nyiaj-grey zaj duab xis (feem ntau 8-12 µm) muab cov tshuaj ntsev-txheej zoo tshaj 720 teev, deb tshaj tus qauv kub-dip galvanizing lossis electroplating ntawm threaded Cheebtsam xws li M12-M72 hex bolts thiab screws.
TSEEM CEEB APPLICATION SCENARIOS RAU DACROMET ANCHOR bolts
Xaiv Dacromet txheej rau lub hauv paus bolts thiab cov txheej txheem fasteners yog feem ntau ncaj ncees nyob rau hauv cov nram no rau 6 scenarios:
| SCENARIO | NTAUB NTAWV & QHOV TSEEM CEEB |
| Ntug hiav txwv & Marine Environments | Cov dej ntsev tsuag corrodes tsis muaj kev tiv thaiv carbon steel bolts thiab screws nyob rau hauv lub lis piam. Dacromet thauj tog rau nkoj bolts - los ntawm M16 foundation bolts rau M48 stud bolts - tiv thaiv chloride nres, ua rau lawv thawj qhov kev xaiv rau cov chaw nres nkoj cranes, offshore platforms, jetty lug, thiab seaside cua-turbine yees. |
| Petrochemical & Chemical Cog | Reactor foundations, pipeline support, thiab nkoj thauj tog rau nkoj bolts raug rau acids, alkalis, thiab tshuaj fumes. Dacromet-coated hnyav hex bolts thiab stud bolts (Qib 8.8 / 10.9) tswj kev ncaj ncees qhov twg cov txheej txheem zinc plating tsis ua haujlwm, txo qis kev saib xyuas tsis tu ncua ntawm cov khoom siv txheej txheem tseem ceeb. |
| Cua & Solar Power Structures | Ntauwd thauj tog rau nkoj bolt tawb thiab hnub ci-rack screws yuav tsum nyob rau 20+ xyoo sab nraum zoov. Dacromet txheej ntawm M30-M72 thauj tog rau nkoj bolts tshem tawm qhov kev pheej hmoo ntawm hydrogen embrittlement cuam tshuam nrog electroplating - qhov tseem ceeb rau lub zog siab (Qib 10.9) cov qauv bolts siv hauv turbine foundations. |
| Txoj Kev, Choj & Tunnel Infrastructure | Kev nthuav dav pob qij txha, guardrail bolts, ntws bolts, thiab qhov av pob zeb-bolt anchors ntsib txoj kev ntsev, deicing tshuaj, thiab dej hauv av. Dacromet fasteners ua raws li cov qauv kev tiv thaiv corrosion rau steel qauv hauv txoj kev loj thiab kev tsheb ciav hlau choj. |
| Automotive & Khoom hnyav | Chassis foundation bolts, suspension screws, thiab brake-system fasteners xav tau cov txheej txheem nyias nyias uas khaws cov xov zoo. Dacromet's uniform 8 µm txheej tsis hloov cov txiv ntoo-bolt haum rau M8-M24 zoo-xov xov screws, tsis zoo li cov tuab tuab kub-dip galvanized txheej. |
| Underground & Embedded Concrete Anchors | Thauj tog rau nkoj bolts cam khwb cia rau hauv pob zeb hauv paus rau cov tshuab hnyav, steel kem, thiab prefabricated qauv tau txais txiaj ntsig los ntawm Dacromet's adhesion rau steel thiab compatibility nrog cementitious ib puag ncig. Qhov no yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig rau J-bolts, L-bolts, thiab taub hau thauj tog rau nkoj rods hauv kev lag luam cog hauv paus. |
DACROMET VS. KUB-DIP GALVANIZING: Kev sib piv nrawm
| QHOV TSEEB | DACROMET | Kub-dip GALVANIZING |
| Txheej Thickness | 8-12 µm | 45-85 µm |
| Xov Tolerance | Tsis cuam tshuam | Tej zaum yuav tau rov tapping |
| Ntsev-Spray Resistance | ≥720 teev | ≥ 500 teev (ntev) |
| H₂ Embrittlement | Tsis muaj | Ua tau (electroplating) |
| Kev khiav hauj lwm Temp. | Txog li 300 ° C | Txog li 200 ° C |
| Hom Bolt Loj | M6-M72 | M10-M100 |
| Zoo tshaj rau | Precision threads, high-strength Qib 10.9 bolts, nyias-wall screws | Cov qauv hlau, loj thauj tog rau nkoj bolts |
