Executive Summary
| Cov Ruspert composite washer drilling ntsia hlau yog ib tug hwm tus kheej-drilling ntsia hlau engineered rau hlau-rau-hlau thiab hlau-rau-tug ntoo fastening nyob rau hauv nruj sab nraum zoov ib puag ncig. Los ntawm kev sib txuas cov rooj plaub-hardened steel ntsia hlau lub cev, ib qho kev xyaum taw tes uas ua ib kauj ruam drilling thiab tapping, thiab Bonded EPDM composite sealing ntxhua khaub ncaws, tsev neeg ntsia hlau no yog tsim rau lub neej ntev los tiv thaiv xeb. Tiv thaiv los ntawm Ruspert ceramic-organic anti-xeb txheej, cov screws xa mus rau 1,000+ teev ntawm ntsev tsuag tsis kam tsis muaj xeb liab - deb tshaj li cov pa electro-plated screws. Kab lus no piav qhia txog cov qauv ntsia hlau, cov cuab yeej tiv thaiv corrosion tom qab txheej txheej, tshawb xyuas cov ntaub ntawv pov thawj tiv thaiv xeb, thiab cov tswv yim xaiv thiab kev taw qhia rau kev vov tsev, cladding, thiab hnub ci mounting tej yaam num. |
1. Dab tsi yog Composite Washer Drilling Screw?
A composite washer drilling ntsia hlau (tseem hu ua tus kheej-drilling ntsia hlau nrog sib khi sealing ntxhua khaub ncaws) yog ib txoj hlua khi uas ua tau peb txoj haujlwm hauv ib qho kev tsav tsheb nkaus xwb: drilling, thread-forming, thiab sealing. Tsis zoo li qhov zoo tib yam tus kheej tapping screws, qhov sib xyaw ua ke ntawm qhov drilling tshem tawm qhov xav tau rau kev xyaum ua ntej.
Lub vulcanized EPDM roj hmab ntxhua khaub ncaws - khi rau lub galvanized steel backing cap - compresses tiv thaiv lub vaj huam sib luag saum npoo los tsim cov huab cua-nruj, leak-proof seal.
| Hauv cov ntsiab lus yooj yooj yim: ib lub hau ntswj hloov lub laum me ntsis, tapping ntsia hlau, thiab lub tshuab ntxhua khaub ncaws sib cais - thiab nws ua rau xeb thiab dej nag ntau xyoo. |
Cov khoom tsev feem ntau npog:
- Hex washer taub hau (HWH) drilling screws- tus qauv kev lag luam vov tsev
- Countersunk (lub taub hau tiaj tus) drilling screws- rau cov ntawv thov ua kom tiav
- Yias / khawm taub hau drilling screws- rau cov ntawv hlau thiab ductwork
2.Anatomy ntawm Screw
| Cheebtsam | Khoom siv & Tsim | Muaj nuj nqi |
| Lub taub hau | Hex washer taub hau nrog serrated flange (los yog countersunk) | High torque kis tau tus mob; flange faib cov clamping load |
| Composite ntxhua khaub ncaws | EPDM roj hmab vulcanized rau zinc-plated / 304 stainless hlau cap | Huab cua nruj; absorbs kev co; UV thiab ozone tiv taus, -40 ° C rau + 120 ° C kev pabcuam |
| Shank & xov | Case-hardened carbon steel (C1022A), dov xov | High thread-forming zog; dov threads nce qaug zog tiv thaiv |
| Drill point | Hardened laum taub, HRC 55-60 | Drills los ntawm cov hlau mus txog 6.0 hli tuab hauv ib qho kev ua haujlwm |
| Txheej | Ruspert ceramic-organic composite txheej | Lub neej ntev tiv thaiv xeb thiab tiv thaiv corrosion barrier |
Cov qauv khoom: GB/T 15856.4 / DIN 7504 K (hex flange taub hau nws tus kheej tho screws); Xov rau GB / T 5280 / ISO 1478.
3.Ruspert Txheej: Ceramic-Organic Anti-Corrosion Technology
- Barrier tiv thaiv- cov phaj zoo li hlau flakes tsim ib txoj kev tortuous uas thaiv dej, oxygen, thiab chloride ions kom ncav cuag cov hlau substrate.
- Kev tiv thaiv kev txi- zinc tivthaiv corrodes nyiam, muab galvanic (cathodic) tiv thaiv txawm tias cov txheej yog khawb ntawm qhov xyaum taw tes lossis xov crests.
- Tsis muaj hydrogen embrittlement txaus ntshai- tsis zoo li electro-plating, Ruspert yog cov txheej txheem tsis-electrolytic dip-spin, yog li tsis muaj hydrogen them ntawm lub cev tawv tawv.
- Dimensional stability- cov txheej tsim tsuas yog 6-12 µm ntawm tuab, yog li cov xov khaws lawv qhov ntsuas thiab sib sau ua ke tsis muaj rov tapping.
Piv nrog rau cov ntsia hlau ua tiav, Ruspert zaum saum toj kawg nkaus ntawm cov nqi tiv thaiv corrosion:
| Ua kom tiav | Hom ntsev tsuag rau liab xeb (ISO 9227 / ASTM B117) | Tus nqi txheeb ze | Sau ntawv |
| Dawb / xiav zinc plating | 24-72 : kuv | Tsawg | Sab hauv lossis qhuav sab hauv tsuas yog siv xwb |
| Yellow zinc plating | 72-120 Nws | Tsawg-Medium | Teeb pom kev sab nraum zoov |
| Mechanical galvanizing | 240-400 Nws | Nruab nrab | Zoo rau cov ntug hiav txwv fasteners |
| Dacromet / zinc flake (basic) | 480-720 Nws | Nruab nrab-siab | Chrome-free xaiv muaj |
| Ruspert 500 | 500h, tsis muaj xeb | Nruab nrab-siab | Standard sab nraum ru tsev qib |
4. Xaus
Rau sab nraum zoov ntsia hlau fastening qhov twg xeb yog yeeb ncuab, lub Ruspert composite washer drilling ntsia hlau muaj kev sib xyaw ua ke tsis tshua muaj: kev xyaum ua kom yooj yim, EPDM sealing, thiab ceramic-organic anti-corrosion thev naus laus zis ntsuas rau 1,000+ xuab moos ntawm ntsev tsuag kev tiv thaiv. Nws txuas ntxiv lub neej kev pab cuam ntawm kev sib koom ua ke kom haum - thiab feem ntau outlast - lub ru tsev lossis cladding system nws tus kheej, txiav kev tu lub voj voog thiab tag nrho cov nqi ntawm cov tswv cuab.
Rau cov ntaub ntawv kev tshaj lij, cov ntawv tshaj tawm cov tshuaj tsuag ntsev, thiab cov kev cai ntsia hlau tshwj xeeb, tiv tauj peb pab pawg xa tawm.
