RUSPERT Self-Tapping Screws-Ib Txheej Txheem Txheej Txheem ntawm Anti-Corrosion Self-Tapping Fasteners
2026-07-13 IB
Self-tapping screws nrog RUSPERT nto kev kho mob muab qhov yooj yim ntawm xov-txhim installation nrog ib tug hwm peb-txheej txheej los tiv thaiv corrosion txheej txheem. Cov ntaub ntawv no muab cov ntsiab lus tseem ceeb ntawm tus kheej-tapping ntsia hlau hom thiab RUSPERT txheej tshuab uas muab 1,000+ teev ntawm kev tiv thaiv ntsev tsuag yam tsis muaj kev pheej hmoo hydrogen embrittlement.
Ntu 1 — Tus Kheej Tapping Ntsia Hlau Hom
Self-tapping screws tsim lawv tus kheej cov xov sab hauv thaum lub sijhawm teeb tsa, tshem tawm qhov xav tau rau kev ua haujlwm ua ntej tapping. Plaub yam tseem ceeb pab cov ntaub ntawv sib txawv thiab cov kev xav tau ntawm kev thauj khoom, txhua qhov txawv los ntawm nws cov xov-txhim kho mechanism thiab taw tes geometry.
Hom kev faib tawm
| Hom | Txuj | Kev piav qhia | Zoo tshaj rau |
| Xov-Forming | Hom A / AB / B | Displaces cov ntaub ntawv los tsim cov xov sab hauv. Yuav tsum muaj lub qhov pilot. Tsis muaj cov khoom tshem tawm. | Plastics, mos hlau, ntoo |
| Xov-txiav | Hom F / BF / 25 | Nta txiav flutes uas tshem tawm cov khoom thaum lub sij hawm installation, tsim kom huv si threads. | Cov hlau hnyav dua, cov khoom siv nkig |
| Xov-Rolling | Hom TR / LO-DRIVE | Txias-forms threads tsis txiav. Ua tsis muaj chips. Siab dua loosening kuj. | Sheet hlau, extruded qhov |
| Self Drilling | DIN 7504 / TEK | Integral xyaum-ntsis taw tes xyaum thiab kais dej hauv ib qho haujlwm. Tsis xav tau lub qhov pilot. | Nyias-gauge steel, HVAC, ru tsev |
Common Standards & Materials
Qauv: DIN 7976, DIN 7504, ISO 15480, GB / T 43655
Khoom siv: Carbon steel (C1018-C1045), hlau alloy, stainless hlau
Hom Lub taub hau: Lub taub hau lub taub hau, countersunk (pav lub taub hau), hex taub hau, hex washer taub hau, puag ncig lub taub hau
Ntu 2 — RUSPERT Txheej Technology
RUSPERT (路锈宝) yog qib siab, ib puag ncig tus phooj ywg kho qhov system feem ntau siv rau carbon thiab alloy steel fasteners. Nws siv peb txheej txheej txheej txheej txheej uas sib xyaw ua ke kev tiv thaiv galvanic nrog kev ruaj ntseg ceramic barrier, ua tiav 1,000-1,500 teev ntawm nruab nrab ntsev tsuag tsis kam - deb tshaj li cov pa zinc plating.
Peb txheej txheej
| Txheej | Kev sib xyaw | Muaj nuj nqi | Mechanism tiv thaiv |
| Txheej 1 - Hlau Zinc | Electrodeposited zinc | Sacrificial cathodic tiv thaiv rau steel substrate | Galvanic - zinc corrodes nyiam dua |
| Txheej 2 - Kev hloov tshuaj lom neeg | Chromate / passivation zaj duab xis | Txhawb nqa adhesion ntawm zinc thiab ceramic txheej | Chemical bonding + kho tus kheej |
| Txheej 3 - Ci Ceramic Topcoat | Zinc-aluminium flake + cob | Barrier tiv thaiv ya raws, ntsev, oxygen thiab tshuaj | Lub cev barrier + non-conductive |
Peb txheej yog sib koom ua ke los ntawm kev siv tshuaj lom neeg, tsim cov yeeb yaj kiab ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Qhov kev sib xyaw tshwj xeeb ntawm cov khaubncaws sab nraud povtseg muab ob qho tib si nquag (saib) thiab passive (barrier) tiv thaiv corrosion.
Qhov Zoo Tshaj Plaws
Superior corrosion kuj: 1,000-1,500 teev nruab nrab ntsev tsuag (NSS) ib ISO 9227, piv rau 96-240 teev rau cov txheej txheem zinc plating.
Tsis muaj hydrogen embrittlement: Cov txheej txheem ua kom kub qis tsis txhob nqus cov hydrogen, ua rau RUSPERT muaj kev nyab xeeb rau cov khoom siv zog siab (Qib 8.8-12.9) qhov twg electroplating ua rau muaj kev pheej hmoo ntawm embrittlement.
Higher deg hardness: RUSPERT txheej yog nyuaj dua Dacromet, muab superior hnav thiab khawb kuj thaum lub installation thiab kev pab cuam.
Tiv thaiv bimetallic corrosion: Cov txheej tsis yog-conductive ceramic topcoat cais cov zinc txheej los ntawm kev sib cuag nrog cov hlau tsis sib xws (piv txwv li, aluminium, galvanized steel), tshem tawm galvanic corrosion ntawm cov qauv uas nyob ib sab.
Environmentally raws: Cr⁶⁺-dawb, RoHS thiab REACH raws. Tsis muaj tshuaj lom hexavalent chromium siv hauv cov txheej txheem.
Txheej sib piv
| Khoom | RUSPERT | Zinc Plating | Dacromet |
| Salt Spray (hli) | 1,000 – 1,500 | 96-240 : kuv | 500-1,200 Nws |
| Hydrogen embrittlement | Tsis muaj | Risk (Qib 10.9+) | Tsis muaj |
| Nto Hardness | Siab | Nruab nrab | Nruab nrab |
| Cr⁶⁺ Pub dawb | Yog lawm | Ntau yam | Yog lawm |
| Qhov tshwm sim | Tsaus grey / dub | Xiav-dawb / ntshiab | Nyiaj-grey |
| Bimetallic Corrosion | Tiv thaiv | Ua tau | Txo |
| Tus Nqi Theem | Nruab nrab-siab | Tsawg | Nruab nrab |
Tshuaj tsuag ntsev raws ISO 9227 NSS. Bimetallic corrosion yog hais txog galvanic nres thaum RUSPERT-coated fasteners hu rau txhuas los yog galvanized steel nto.
Daim ntawv thov
Ntug hiav txwv & Marine: Lub ru tsev, cladding, thiab cov qauv kev sib txuas nyob rau hauv ntsev-laden atmospheres.
Sab nraum zoov cov qauv: Fencing, decking, pergolas, thiab architectural facades raug huab cua.
ACQ-kho ntoo: RUSPERT tiv taus cov corrosive tooj liab-raws li preservatives nyob rau hauv niaj hnub siab-kho ntoo.
Automotive: Hauv qab lub cev fasteners, chassis txuas, thiab tso pa tawm system txuas.
Cua zog & steel framing: Kev sib txuas ntawm lub neej ntev uas xav tau kev saib xyuas tsis muaj kev tiv thaiv corrosion.
Cov ntsiab lus
RUSPERT-coated self-tapping screws muab kev sib xyaw ua ke ntawm kev yooj yim installation thiab kev tiv thaiv corrosion mus ntev. Tus kheej tapping tsim tshem tawm ua ntej tapping, thaum peb-txheej RUSPERT system muab 1,000+ teev ntawm ntsev tsuag tshuaj tiv thaiv tsis muaj hydrogen embrittlement - ua cov fasteners zoo tagnrho rau sab nraum zoov, ntug hiav txwv dej, thiab chemically aggressive ib puag ncig uas cov pa zinc plating yuav ua tsis tiav ntxov.
