Rail Padyog ib qho kev ua haujlwm tshwj xeeb uas tsim los ua kom tau raws li qhov tsawg -cov suab nrov ntawm kev tsheb ciav hlau hauv nroog. Los ntawm kev sib koom ua ke cov qauv ntxeem tau yooj yim, roj hmab- cov ntaub ntawv ua npuas dej, lossis cov txheej txheem txheej txheej txheej txheej, nws tuaj yeem txo lub log- cov suab nrov ntawm kev sib cuag los ntawm 8-15 dB thaum txo qis kev sib kis mus rau ib puag ncig ib puag ncig. Qhov no ua tau raws li qhov xav tau ntawm ib puag ncig lub suab nrov txo rau cov kab nyob ze hauv nroog cov cheeb tsam tseem ceeb thiab thaj chaw nyob, ua rau nws yog ib qho tseem ceeb ntawm kev ua haujlwm uas sib npaug ntawm kev ua haujlwm thiab ib puag ncig tus phooj ywg.
Yuav ua li cas hloov lub voj voog rau rail pads txiav txim?
Rail pad hloov lub voj voog yog txiav txim siab los ntawm kev sib xyaw ntawm kev tshuaj ntsuam xyuas, kev soj ntsuam kev ua tau zoo (nruj, kev vibration), thiab cov khoom siv degradation, ntsuas qhov kev cia siab ntawm lub neej (8-25 xyoo rau roj hmab) nrog rau kev ua haujlwm xws li kev khiav tsheb, ib puag ncig, thiab cov txheej txheem tshwj xeeb xws li <20% mus tas li compression lossis kev hloov nruj, kom muaj kev nyab xeeb thiab kev ua haujlwm.
Yam Tseem Ceeb & Txoj Kev
Kev Tshuaj Xyuas Kev Pom Zoo: Kev tshuaj xyuas tsis tu ncua rau cov kab nrib pleb, kev hloov xim, lossis cov khoom txawv teb chaws; yuav tsum tau hloov yog tias cov kab nrib pleb> 5mm los yog hnyav hnyav pom.
Material Hardness & Elasticity: Test Shore hardness (piv txwv li, ± 15 degrees los ntawm thawj zaug) lossis tus nqi rov qab (<80% after load) indicates material failure.
Kev hloov tawv tawv: Saib xyuas qhov zoo li qub / dynamic tawv; ib qho kev hloov pauv loj (piv txwv li, 50% kev hloov pauv hauv lub caij nplooj ntoo hlav zoo li qub) lossis tshaj qhov txwv tsis pub dhau (piv txwv li, 15% dynamic stiffness rate hloov) ua rau hloov.
Fatigue & Load Cycles: Siv cov kev sim kuaj (xws li 3 lab lub voj voog) los kwv yees kev ua haujlwm ntawm thaj chaw, feem ntau cuam tshuam nrog kev hloov pauv.
Kev vibration & suab nrov: ntsuas kev vibration txo; yog tias kev ua haujlwm poob qis dua cov qauv (xws li,<20dB for urban lines), pads are replaced.
Environmental Factors: UV, kub heev, thiab tshuaj lom neeg ua rau kev laus, cuam tshuam rau lub sijhawm txij nkawm.
Dab tsi yog cov khoom siv hauv kev tsheb ciav hlau?
Railway pads siv cov ntaub ntawv elastic zoo li Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Polyurethane (PU), thiab High-Density Polyethylene (HDPE), feem ntau ua ke nrog cov fillers xws li carbon dub, kom nqus tau kev poob siab, txo suab nrov, thiab tiv thaiv cov neeg pw tsaug zog los ntawm kev hnav, nrog rau cov kev xaiv niaj hnub no kuj suav nrog cov khoom siv polymers kom ruaj khov.

Rail pad muaj nuj nqi
Rail roj hmab ncoo yog qhov tseem ceeb hauv kev txo qis kev poob siab thiab kev co hauv lub tsheb ciav hlau. Lub ncoo nteg nyob rau hauv lub tsheb ciav hlau los xyuas kom meej:
- Load faib tshaj qhov loj dua
- Tshem tawm ntawm load concentration thiab ua rau qaug zog stresses
- Centering ntawm loads ntawm cov khoom txhawb nqa
- Kev nqus ntawm qhov tsis sib xws ntawm qhov chaw sib txuas ntawm kev tsheb nqaj hlau thiab kev txhawb nqa
- Txo cov suab nrov thiab kev co
- Kev sib khi ntawm lub hauv qab ntawm txoj kev tsheb ciav hlau thiab sab saum toj ntawm kev txhawb nqa
- Txo kev hnav ntawm txoj kev tsheb ciav hlau thiab nws cov kev txhawb nqa
GNEE RAIL muab tshwj xeeb elastic rail pads ntawm ntau hom rau siab - kev tsheb ciav hlau ceev, ib txwm - kev tsheb ciav hlau ceev, thiab cranes. Tshwj xeeb tshaj yog cov rail pads ua los ntawm roj hmab, EVA, TPEE, thiab HDPE yog heev nrov nrog cov neeg muas zaub. Peb cov railway roj hmab pads haum rau rails xws li UIC54, UIC60, BS80lbs, BS100lbs, thiab lwm yam. Peb muaj ntau tshaj 130set ntawm cov cav tov nyob rau hauv peb cov kab ntau lawm uas muaj peev xwm ncav cuag ib xyoos twg muaj peev xwm mus txog 2000, 000 daim ntawm rail pads. Peb muab ntau hom kev tsheb ciav hlau thiab lwm cov ntaub ntawv taug qab ntawm tus nqi sib tw.
