Covrail ncoo, los yog hu ua rail elastic pad, hais txog ib lub ncoo ua los ntawm roj hmab los yog yas, uas yog ntsia nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb hauv qab - txoj kev tsheb ciav hlau. Lub luag haujlwm tseem ceeb ntawm kev tsheb ciav hlau elastic ncoo yog kom tsis txhob muaj qhov siab - nrawm nrawm thiab kev vibration tsim thaum lub tsheb hla txoj kev tsheb ciav hlau, tiv thaiv txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog, thiab hluav taws xob rwb thaiv tsev cov teeb liab kev tsheb ciav hlau.
Yuav ua li cas kuaj qhov zoo ntawm rail pads?
Kev ntsuas kev tsheb ciav hlau zoo suav nrog kev sib xyaw ntawm kev sim thiab kev sim teb, tsom rau cov khoom siv (hardness, elasticity, aging) thiab dynamic kev ua tau zoo (kev co / suab nrov damping, cuam tshuam tsis kam) siv txoj kev xws li Shore hardness tests, compression sets, dynamic load testing, and vibration/noise measurement under simulated or real train loads, kom paub tseeb tias lawv ({0} hnyav -haul).
Laboratory Tests (Material & Static)
- Hardness: Shore Ib qho kev ntsuas hardness ntsuas qhov tawv, feem ntau tom qab txias txias (-40 degree) los xyuas qhov ntsuas kub qis, kom ntseeg tau tias nws tsis nkig.
- Compression Set: Tshawb xyuas seb lub ncoo rov qab zoo li cas tom qab lub sijhawm ntev, qhov tseem ceeb rau kev tswj xyuas elasticity.
- Cov Khoom Siv Cov Khoom Siv: Tshawb xyuas kev siv cov roj hmab zoo / elastomers, tsis siv cov khoom siv rov ua dua tshiab, nrog rau kev ntsuam xyuas tshwj xeeb, cov ntsiab lus tshauv, thiab lwm yam.
- Environmental Resistance: Kev ntsuam xyuas rau UV, ozone, nqus dej, thiab tiv thaiv cov ntsev / tshuaj.
- Load-Deflection: Quasi- kev ntsuam xyuas zoo li qub (piv txwv li, mus rau 250kN) xyuas cov load-cov kabmob muaj peev xwm thiab qhov tawv nqaij.
Dab tsi yog rail pads ua los ntawm?
GNEE RAIL tau tsim ntau yam ntawm -kev ua tau zoo elastic rail pads rau nruj raws li qhov yuav tsum tau muaj thiab ntau yam kev thov hauv cheeb tsam- los ntawm cov tsheb ciav hlau los ntawm cov qauv ntsuas kev tsheb ciav hlau mus rau cov kab tsheb hnyav, tshwj xeeb tshaj yog rau E- hom tsheb ciav hlau fastening systems thiab SKL hom tsheb ciav hlau fastening systems nrog cov khoom ntawm HDPE/EVA/Rub.

Cov yam ntxwv ntawm Rubber Rail Pads
- Kev ua haujlwm zoo rau kev co thiab kev laus, kev ua haujlwm puas, ruaj khov, siab thiab kub tsis kam. Cov roj hmab rail pads yog tsim los ntawm cov roj hmab ntuj, styrene, chloroprene thiab siab - ntom polyethylene, thiab cov roj hmab rail ncoo muaj siab elasticity thiab tsis yooj yim rau deform los yog tawg nyob rau hauv ntau qhov kub thiab txias.
- Roj hmab rail ncoo muaj lub neej ntev kev pab cuam, tsis tshua muaj txij nkawm thiab hloov nqi.
- Nrog lub zog muaj zog, zoo tiv thaiv- kev ua haujlwm poob siab, kev ua haujlwm zoo rwb thaiv tsev, hnav- tiv taus, tsis tshua muaj shrinkage thiab deformation, lub zog siab, kev laus ua haujlwm, tsis muaj av nkos, kev ua haujlwm ntev thiab kev teeb tsa yooj yim. Qhov tsim nyog siv cov roj hmab rail pads tuaj yeem txhim kho lub peev xwm ntawm kev thauj mus los ntawm lub cev muaj zog, txo tus naj npawb ntawm txoj kev loj, thiab tsis txhob muaj xwm txheej tshwm sim los ntawm lub tsheb hluav taws xob.
Raws li ib tug kws tshaj lij rail fastener chaw tsim tshuaj paus, GNEE RAIL tuaj 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.
