- EPDM (Ethylene Propylene Diene Monomer):Siv rau nws cov huab cua thiab aging kuj.
- Composite Pads:Kev sib xyaw ntawm cov khoom siv rau kev ua tau zoo dua qub, zoo li grooved composite sole daim hlau.
Hom los ntawm Tsim / Daim Ntawv Thov
- Grooved Pads:Muaj grooves kom haum rau cov kev tsheb ciav hlau tshwj xeeb, muab kev cuam tshuam zoo dua thiab lub neej.
- Studded Pads:Feature studs rau nce tuav thiab durability nyob rau hauv xav tau tej yam kev mob.
- Square Pads:Cov duab square yooj yim rau kev siv dav dav, feem ntau hauv kev nrawm - kos tshuab.
- Nruam & Discontinuous Pads:Siv rau cov qauv sib txawv ntawm cov qauv tsim, tshwj xeeb tshaj yog rau cov cranes.
Common Systems Txhawb
Rail pads yog tsim los rau tshwj xeeb fastening systems, xws li E-type, SKL, KPO, thiab lwm yam, kom phim cov tsheb ciav hlau profile thiab taug qab cov kev cai.
Rail pads rau E- hom rail fastening systems
Rail roj hmab pads siv rau E- hom tsheb ciav hlau fastening systems yog nrog cov haujlwm zoo sib xws ntawm cov tsheb ciav hlau insulators los thaiv cov tsheb ciav hlau saum toj no los ntawm cov hlua khi pw hauv qab nws, kom muaj kev tiv thaiv zoo tiv thaiv kev co thiab cov qauv- ua suab nrov zoo li. rail ncoo ua hauj lwm ua ke nrog e-clip, rail insulators / insulated gauge blocks thiab rail lub xub pwg nyom / embedded qhov chaw los ua ib tug tag nrho cov E- hom rail fastening system.
Rail pads rau SKL rail fastening systems
Lub rail ncoo hauv SKL rail fastening system yog ib qho me me tab sis tseem ceeb heev, ua haujlwm ua ke nrog SKL clips, ntsia hlau spikes, yas dowels, phau ntawv qhia thiab lwm yam. Lub elastic rail pads peb tsim muaj ib qho kev nruj nruj thiab ua kom pom tseeb tias qhov elasticity ntawm txoj kev khiav superstructure. Nrog rau qib siab dua ntawm elasticity, nws pab txhawb rau kev khiav ntsiag to ntawm cov khoom dov, kom ua tau raws li niaj hnub no acoustic xav tau ntawm cov kab tsheb ciav hlau.
GNEE RAILMuaj ntau hom kev tsheb ciav hlau fasteners kom tau raws li cov neeg siv khoom xav tau, xws li Elastic Rail Clip thiab Clamp, Rail Screw Spike, Yas Dowel, High Tensile Track Bolt nrog txiv ntseej, Rail Base (Tie) Phaj, Rail Fish Phaj, Rail Lub xub pwg (Ntxig), Ntses Bolt, Railroad Rubber thiab EVA Pad, thiab lwm yam.
