A rail ncoo, tseem hu ua rail roj hmab phaj, yog tsim los ntawm lub tsheb ciav hlau khi phaj thiab ko taw ntawm txoj kev tsheb ciav hlau, ua los ntawm elastic polyurethane lev, uas yog interposed ntawm steel rails thiab khi sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam. Nws txoj kev nruj nruj yog siv los ua kom lub elasticity ntawm lub superstructure ntawm lub ballast thiab txo kev poob siab thiab kev vibration hauv txoj kev tsheb ciav hlau.

Yuav ua li cas puas rail elastic pads?
Rail elastic pads tau txais kev puas tsuaj los ntawm kev thauj khoom ntau dhau / siab (hnyav / ceev tsheb ciav hlau, nruj nkhaus), ib puag ncig (mob siab heev, UV, ozone), kev sib kis ( av, roj), kev co, kev teeb tsa tsis raug (tsis txaus clamping), thiab cov khoom laus / qhov tsis xws luag, ua rau qaug zog, tawg, poob elasticity, lossis lawv lub cev kev ua haujlwm thiab tag nrho cov kev ua haujlwm.
Mechanical Factors
- Overloading/High Stress: Cov tsheb ciav hlau hnyav, kev kub ceev, thiab cov nkhaus nkhaus ua rau muaj zog loj, ua rau puas tsuaj, khoov, thiab qaug zog.
- Kev vibration & txav mus: Kev tsheb ciav hlau tsis tu ncua thiab kev tsheb ciav hlau wobbling (vim yog xoob fasteners) ua rau pob zeb, kev sib txhuam, thiab tshem tawm ntawm lub ncoo.
- Tsis txaus Clamping Force: Yog tias cov fasteners tsis nruj, lub tsheb ciav hlau tuaj yeem nqa thiab pob zeb, ua rau lub ncoo ua rau puas tsuaj.
Environmental & Chemical Factors
- Kub kub heev: Kub kub ua rau nthuav / buckling; txias ua rau lawv nkig; Ntev raug degrades roj hmab.
- Ozone & UV raug: Cov roj hmab ntuj tawg, dries tawm, thiab poob resiliency ntawm lub hnub thiab ozone.
- Kev Tiv Thaiv: Cov av, grit, lossis txawm tias cov roj tuaj yeem raug daig, ua rau puas tsuaj thiab tshuaj lom.
Cov teeb meem khoom siv & kev tsim khoom
- Cov Khoom Siv Tsis Zoo: Cov vulcanization tsis zoo, siab deformation mus tas li, lossis cov khoom siv tsis zoo hauv lub cev ua tsis tau sai.
- Kev laus: Tag nrho cov roj hmab pads degrade dhau sijhawm, poob elasticity thiab ua rau tawg.
Yuav ua li cas thiaj tswj tau txoj kev tsheb ciav hlau?
Kev tuav txoj kev tsheb ciav hlau yuav tsum tsis tu ncua, teem caij tshuaj xyuas rau hnav (kawg, deformation), xyuas kom cov fasteners nruj, ua kom thaj tsam kom tsis txhob muaj cov khib nyiab thiab dej, thiab hloov cov ntaub qhwv thaum lawv dhau qhov kev txwv (xws li 20% compression) kom tswj kev ruaj ntseg, txo suab nrov, thiab kev nyab xeeb.
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.
