A Railway Track Fitting Rubber Pad(los yog rail ncoo) yog ib qho elastic tivthaiv muab tso rau nruab nrab ntawm lub steel rail thiab cov pob zeb pw tsaug zog, ua raws li ib tug poob siab absorber kom txo tau kev co, cuam tshuam, thiab suab nrov los ntawm cov tsheb ciav hlau hla, uas tiv thaiv taug qab infrastructure, ua rau kom muaj kev ruaj ntseg, minimizes txij nkawm, thiab txhim kho kev nplij siab.
Dab tsi yog cov khoom siv tseem ceeb hauv Elastomeric Rail Pad?
Cov khoom tseem ceeb hauv elastomeric rail pads yog roj hmab, feem ntau cov roj hmab ntuj (xws li Ribbed Smoked Sheet - RSS) los yog cov khoom sib txawv xws li Styrene Butadiene Rubber (SBR) thiab Poly Butadiene Rubber (PBR), qee zaum sib xyaw rau cov khoom tshwj xeeb, muab cushioning, vibration damping, thiab hluav taws xob rwb thaiv tsev ntawm cov tsheb ciav hlau.
Cov ntaub ntawv tseem ceeb & hom
- Ntuj Roj Hmab (NR): Ib txwm xaiv, paub txog kev ua haujlwm ntev, tab sis feem ntau sib xyaw.
- Synthetic Rubbers: SBR thiab PBR feem ntau sib xyaw nrog cov roj hmab ntuj.
- EPDM Roj Hmab: Siv rau nws zoo heev tiv taus huab cua, tshuaj lom neeg, thiab kub kub, featuring ib tug ruaj khov polymer saw.
- Thermoplastic Elastomers (TPE / TPEE) & Polyurethane (PU): Kuj tseem siv tau, muab cov khoom sib txawv thiab hloov tau yooj yim.
- High-Density Polyethylene (HDPE) & Ethylene-Vinyl Acetate (EVA): tuaj yeem siv tau, qee zaum ua ke nrog roj hmab.

Dab tsi ntawm txoj kev tsheb ciav hlau tuaj yeem siv cov roj hmab hauv tsheb?
Rail roj hmab pads muaj ntau yam, siv nyob rau hauv nroog tsheb thauj mus los (subways, lub teeb rail), siab - ceev railways, hnyav- cov kab, thiab cov pa railways, muab kev co / suab nrov damping, shock absorption, thiab taug qab kev tiv thaiv, haum rau cov pob zeb los yog ntoo pw tsaug zog nyob rau hauv ntau yam kev tsheb ciav hlau hom (UIC, BS, JIS). Lawv yog ib qho tseem ceeb rau kev txhim kho kev nplij siab, txuas ntxiv lub neej khiav, thiab txo kev txij nkawm ntawm ntau hom kev tsheb ciav hlau.
Hom Railways & Daim Ntawv Thov:
- Nroog Rail Transit (Subways, Lub Teeb Rail): Ua kom pom tseeb ntawm lub suab nrov thiab kev vibration cais rau cov neeg caij tsheb, siv cov ntaub qhwv nyias nyias.
- High -Speed Railways: Xav tau siab elasticity thiab resilience los lis dynamic loads, feem ntau nrog composite pads.
- Heavy-Haul Lines: Yuav tsum tau cov ntaub tuab, muaj zog dua (12-20mm) txhawm rau cushion hnyav qag loads thiab txo qis ballast hnav.
- Pa Railways: Siv nyob rau hauv tus qauv lem rau kev co thiab txo hnav.
Raws li ib tug kws rail fastener chaw tsim tshuaj paus,GNEE RAILtuaj yeem tsim ntau hom roj hmab rail pads nrog cov ntaub ntawv sib txawv, xws li roj hmab ntuj, EVA, HDPE thiab lwm yam. Nyob rau hauv railway fastening system, roj hmab rail pads feem ntau ntsia nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb railway sleepers.
