A rail ncooyog muab tso rau hauv nruab nrab ntawm lub tsheb ciav hlau thiab baseplate los yog sleeper. Rail ncoo yog qhia rau txoj kev tsheb ciav hlau fastening system vim nws cov resilience los yog viscoelasticity uas yuav siv tau nyob rau hauv kev cuam tshuam ntawm qaug zog cracking ntawm pw tsaug zog. Lub dynamic kev ntxhov siab los ntawm lub log los yog kev tsheb nqaj hlau cuam tshuam los ntawm ob qho tib si tsis tu ncua thiab tsis xwm yeem txav yog attenuated.
Daim ntawv thov ntawm rail elastic pads nyob rau hauv railways
Rail elastic pads, ua los ntawm cov roj hmab los yog polyurethane, yog cov khoom tseem ceeb nyob rau hauv nruab nrab ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog (kev sib txuas) kom nqus tau qhov cuam tshuam, dampen vibration, thiab faib cov tsheb ciav hlau thauj khoom, txo cov suab nrov, tiv thaiv infrastructure ntawm hnav (tshwj xeeb yog cov pob zeb sib txuas), ua kom muaj kev ruaj ntseg, thiab txhim kho cov neeg caij tsheb, ua rau lawv tseem ceeb rau niaj hnub, siab {{0} kev tsheb ciav hlau, thiab kev sib tw.
Qhov twg lawv siv:
- Pob Tawb Sleepers: Tshwj xeeb tshaj yog tseem ceeb nrog cov pob zeb sib txuas los tiv thaiv kev qaug zog thiab kev puas tsuaj los ntawm kev cuam tshuam thiab kev co.
- High -Speed Lines: Nws yog ib qho tseem ceeb rau kev tswj hwm lub zog muaj zog thiab ua kom muaj kev ruaj ntseg thiab kev nplij siab ntawm kev ceev.
- Ballastless Tracks: Siv nyob rau hauv cov txheej txheem fastening rau slab lem.
- Transition Zones: Pab tswj kom muaj kev ntxhov siab ntxiv ntawm qhov chaw xws li choj txoj kev los yog qhov chaw taug kev hloov pauv.
Qhov kev pab cuam lub neej ntawm rail pads yog dab tsi?
Rail pad kev pab cuam lub neej sib txawv ntawm cov khoom, ib puag ncig, thiab kev khiav tsheb, feem ntau kav ntev li 8 txog 25 xyoo, nrog cov khoom siv xws li roj hmab (5-8 xyoo), HDPE (10-15 xyoo), thiab cov khoom sib xyaw (8-12 xyoo) muab qhov sib txawv, txawm tias cov tshuab siab heev thiab kev saib xyuas zoo tuaj yeem txuas ntxiv rau xyoo no mus rau ntau xyoo, raws li pom nrog kev ua haujlwm siab 6 xyoo.
Tej yam cuam tshuam rau Lifespan
- Khoom siv: Cov roj hmab ntuj degrades sai dua (5-8 xyoo) dua li cov yas tawv zoo li HDPE (10-15 xyoo), thaum cov khoom sib npaug sib npaug ntawm cov cushioning thiab hnav.

- Tsheb thauj mus los: Siab- zaus, hnyav, tshwj xeeb tshaj yog nyob rau hauv nkhaus, ua kom hnav.
- Ib puag ncig: raug rau qhov kub thiab txias, UV, lossis tshuaj ua rau lub neej luv.
- Kev Kho: Kev kuaj xyuas tsis tu ncua, ntsia liaj qhov rooj re-torquing, thiab hloov raws sij hawm ntawm cov ntaub qhwv degraded ncua lub neej.
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.
