Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm Rail Pads?
Rail padsmuaj qhov zoo xws li txo qis hnav thiab suab nrov, txhim kho kev ruaj ntseg, thiab txhim kho cov neeg caij tsheb kev nplij siab, feem ntau los ntawm dampening vibrations thiab faib loads. Txawm li cas los xij, qhov tsis zoo suav nrog cov nqi pib siab dua rau cov khoom siv siab, muaj peev xwm ua rau tsis zoo nyob rau lub sijhawm los ntawm ib puag ncig, thiab cov khoom siv - cov kev txwv tshwj xeeb xws li txo qis hauv qee cov khoom sib xyaw lossis kev cuam tshuam rau ozone hauv roj hmab.
Qhov zoo
- Kev vibration thiab suab nrov txo:Rail pads nqus siab - zaus vibrations los ntawm cov tsheb ciav hlau hla, uas txo cov suab nrov thiab txhim kho cov neeg caij tsheb.
- Txo hnav thiab tsim kua muag:Los ntawm dampening vibrations, lawv tiv thaiv cov kab ke kev tsim kho, nrog rau cov ballast thiab cov pw tsaug zog, uas txuas ntxiv lub neej ntawm cov khoom no thiab txo cov nqi kho.
- Txhim kho txoj kev ruaj ntseg:Lawv pab tswj kev ncaj ncees ntawm cov txheej txheem ballast thiab tswj kev ruaj ntseg, tshwj xeeb tshaj yog nyob rau hauv hnyav lossis siab - ceev loads.
- Load faib:Lawv kis tau cov load los ntawm txoj kev tsheb ciav hlau mus rau lub sleeper los yog ballast, tiv thaiv kev ntxhov siab ntau thiab tawg hauv pob zeb pw.
- Tus nqi -efficiency:Txawm hais tias muaj peev xwm ua tau tus nqi siab dua rau qee yam khoom siv, lawv tuaj yeem raug nqi ntau dua - siv tau rau lub sijhawm ntev vim txo kev saib xyuas thiab kev ua haujlwm ntev dua.
Qhov tsis zoo
- Tus nqi pib siab dua:Qee cov ntaub ntawv qib siab, zoo li cov khoom sib xyaw, tuaj yeem muaj tus nqi pib dua piv rau cov ntaub qhwv cov roj hmab.
- Environmental degradation:Cov khoom siv roj hmab ib txwm muaj qhov cuam tshuam rau ib puag ncig xws li UV rays thiab ozone, uas tuaj yeem ua rau lawv tsis zoo rau lub sijhawm.
- Tsawg yooj yooj yim:Qee cov ntaub ntawv sib xyaw tuaj yeem hloov pauv tsawg dua li cov roj hmab, uas tuaj yeem ua rau lawv tsis tshua muaj txiaj ntsig hauv qee yam kev mob lossis kev siv.
- Susceptibility rau tsis ua hauj lwm:Txawm hais tias ruaj khov, cov ntaub qhwv roj hmab thaum kawg yuav txo qis, ua rau muaj peev xwm ua tsis tiav thiab xav tau kev hloov pauv, uas tuaj yeem raug nqi thiab ua rau poob qis.
- Kev ua tau zoo sib txawv:Hom kev tsheb ciav hlau zoo tshaj plaws (piv txwv li, thickness, khoom siv) nyob ntawm daim ntawv thov; ib lub ncoo haum rau siab - kev tsheb ciav hlau ceev yuav tsis zoo tagnrho rau cov kab lus sib dhos thiab rov ua dua.
Rail Pad Khoom
Lub rail ncoo, tseem hu ua hauv qab phaj, yog ib qho elastic polyurethane ncoo sib sau ua ke ntawm cov ntsia hlau thiab pw tsaug zog los tiv thaiv sab saum toj ntawm tus neeg pw tsaug zog los ntawm kev hnav thiab cuam tshuam. Thawj qhov nruj ntawm lub tsheb ciav hlau tsis yog siab heev uas qhov deformation ntawm cov ntsia hlau nyob rau hauv lub load ntawm lub caij nplooj ntoos hlav yog loj heev. Cov txheej txheem no ua kom lub tsheb ciav hlau txav ze li sai tau kom paub txog kev sib raug zoo nrog txoj kev khiav.
Raws li cov chaw tsim khoom ntawm kev tsheb ciav hlau, GNEE RAIL muaj peev xwm tsim cov tsheb ciav hlau ntawm ntau lub tsheb ciav hlau, xws li UIC54, UIC60, BS80lbs, BS100lbs thiab lwm yam. Tsis tas li ntawd, peb tuaj yeem muab kev cai- ua cov ntaub qhwv raws li cov duab kos lossis cov qauv.

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. Peb cov EVA / HDPE / roj hmab rail pads yog nrog siab elasticity, thov rau hom kev tsheb ciav hlau xws li tsheb ciav hlau UIC54, UIC60, BS80lbs, BS100lbs, thiab ntau thiab tsawg raws li tau txiav txim. Cov ntaub qhwv tuaj yeem kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
