Rail Pad yog ib qho tshwj xeeb elastic tivthaiv tsim rau ntau haiv neeg taug qab scenarios. Raws li hom kab, nws suav nrog cov qauv rau kev siab - kev tsheb ciav hlau ceev, hnyav- tsheb ciav hlau, kev tsheb ciav hlau hauv nroog, kev tsheb ciav hlau, thiab lwm yam. Cov ntaub qhwv rau kev siab - kev tsheb ciav hlau ceev yuav tsum muaj qhov siab elastic modulus (15-30 MPa) kom sib npaug smoothness thiab stability; cov uas hnyav- txoj kev tsheb ciav hlau yuav tsum tau ua kom muaj zog compressive (Ntau dua lossis sib npaug li 15 MPa); pads rau tsheb ciav hlau hauv nroog tsom rau cov suab nrov tsawg (tso suab nrov tsawg dua lossis sib npaug li 8 dB); thiab cov ntaub qhwv rau qhov chaw tshwj xeeb xws li cov cheeb tsam txias heev yuav tsum tau qis-kub{11}} cov ntaub ntawv tiv taus (tsis muaj brittleness ntawm -40℃).

Dab tsi yog qhov compressive zog ua raws li tus nqi rau rail pads?
Rail ncoo compressive zog tsis yog ib qho txiaj ntsig tab sis txawv ntawm cov khoom siv (HDPE, Roj Hmab, EVA) thiab tus qauv, tsom mus ntxiv raunruj (kN / mm)rau load kis tau tus mob thiabcompression set (%)rau ntev -lub sij hawm elasticity, nrog rau cov piv txwv zoo li HDPE pads xav tau tsawg dua los yog sib npaug li 25% teeb thiab roj hmab Tsawg dua los yog sib npaug li 30% teem rau tej yam kev mob, thaum lub zog yuav muaj li ntawm 5-92 kN / mm nyob ntawm txoj kev tsim. Kev ua raws cai nyob ntawm lub rooj sib tham tshwj xeebEN / DBS cov qauv(xws li EN 13481, DBS 918235), kuaj static / dynamic loads (piv txwv li, 180 kN), thiab tswj yam xws li compression set thiab hluav taws xob tsis kam.
Cov Kev Ntsuas Qhov Tseem Ceeb:
- Compression Set: Ntsuas qhov deformation mus tas li tom qab tshem tawm, qhia tias elastic rov qab los. Qhov qis dua yog qhov zoo dua (xws li HDPE Tsawg dua lossis sib npaug li 25%, Rubber Tsawg dua lossis sib npaug li 30%).
- Kev nruj (c): Qhov tseem ceeb rau kev thauj khoom thiab kev co dampening, teev nyob rau hauv kN / mm (xws li, 5-92 kN / mm).
- Tensile Strength / Elongation: Cov khoom siv zog (piv txwv li, Roj Hmab Ntau dua lossis sib npaug ntawm 12.8 MPa tensile, Ntau dua lossis sib npaug li 260% elongation).
- Kev Tiv Thaiv Hluav Taws Xob: Yuav tsum muaj kev nyab xeeb ntawm kev taug qab (piv txwv li, Ntau dua lossis sib npaug ntawm 10^6 Ω).
Piv txwv los ntawm Cov Khoom Siv:
- Rubber Pads: Compression teem tsawg dua lossis sib npaug li 30% (25% strain, 70 degree, 22h).
- HDPE Pads: Compression teem tsawg dua lossis sib npaug li 25% (20% strain, 50 degree, 22h).
- EVA Pads: Cov tawv tawv dua, qis qis dua qhov muaj peev xwm, siv rau hauv cov tshuab tsis muaj suab nrov.
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 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 cov ntsia hlau xws li UIC54, UIC60, BS80lbs, BS100lbs, thiab lwm yam. Peb muaj ntau tshaj 130sets 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.
