Rail Pad yog ib qho kev taug kev cushioning tivthaiv nrog cov kua dej thiab qhov cua ua haujlwm. Qee cov qauv muaj cov micron- theem cov grooves thiab qhov cua qhov ntawm ob sab lossis hauv qab, tso cai rau cov dej ntws sai sai thiab txo cov dej noo. Qhov no tiv thaiv lub ncoo los ntawm kev laus thiab tawg vim lub sijhawm ntev immersion thiab inhibits pwm kev loj hlob uas tuaj yeem cuam tshuam cov khoom siv. Nws yog qhov tshwj xeeb tshaj yog haum rau cov dej nag, thaj chaw ntub dej lossis cov kab tsheb ciav hlau hauv av.
Yuav ua li cas xaiv rail pads rau hnyav -haul railways?
Kev xaiv cov tsheb ciav hlau rau hnyav- txoj kev tsheb ciav hlau yuav tsum tau tsom mus rau qhov muaj peev xwm thauj khoom siab, ua haujlwm ntev, thiab ruaj khov, feem ntau yog siv cov khoom hnyav dua, cov khoom tuab zoo li siab -cov roj hmab los yog polyurethane, qee zaum nrog cov hlau reinforcement, los tuav lub qag loj thiab cuam tshuam, kom ntseeg tau tias muaj zog nruj rau cov khoom siv ruaj khov), thiab tsis yog qhov kub thiab txias thiab ib puag ncig tej yam kev mob rau lub neej ntev kev pab cuam.
Rau Hnyav hnyav heev (piv txwv li, Mining):Xaiv rau HDPE nruj lossis roj hmab- cov ntaub qhwv hlau rau qhov siab tshaj plaws thiab kev txhawb nqa.

Rau General Heavy Haul (Ntau dua lossis sib npaug rau 25t Qag Load):Thick, siab -cov roj hmab ntom ntom (15-20mm) muab cov cushioning tseem ceeb thiab ua haujlwm ntev.
Cov Kev Xav Tau Tshwj Xeeb:Xaiv cov ntaub ntawv tshwj xeeb (xws li HNBR lossis polyurethane) rau qhov kub thiab txias los yog siv cov nplaim taws -cov ntaub thaiv npog rau lub qhov.

Rail Pad Function hauv Railway Fastening System
Cov ntaub thaiv npog tiv thaiv kev tsheb ciav hlau - pw tsaug zog puas thiab crushing ntawm tus neeg pw hauv qab txoj kev tsheb ciav hlau. Roj hmab rail pads feem ntau yog tsim los rau ib qho kev teev tseg -deflection yam ntxwv. Thawj qhov tawv tawv ntawm lub tsheb ciav hlau yog tsim los kom qis, lawv deformations nyob rau hauv cov ntiv taw ntiv taw yog qhov tseem ceeb heev. Qhov kev tsim tshwj xeeb no ua rau lub tsheb ciav hlau tseem nyob hauv kev sib raug zoo nrog txoj kev tsheb ciav hlau txawm tias muaj kev txav ntsug ntawm qhov kawg.
Thaum lub log dhau ntawm lub ncoo, tom kawg qhov kev nruj yuav tsum tiv thaiv kev txav loj, thiaj li tiv thaiv lub caij nplooj ntoos hlav hlau tsis dhau. Xws li kev thauj khoom- tus yam ntxwv deflection tuaj yeem tau los ntawm kev qhia cov grooves hauv cov roj hmab rail pads. Roj hmab ncoo los yog grooved roj hmab rail ncoo yog tsim los ntawm roj hmab los yog yas kom dampen lub shocks ntawm vibrations ntawm lub tsheb ciav hlau hla.
GNEE RAILmuab 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.
