Rail padsyog elastic polyurethane lev uas yog interposed ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
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.

Dab tsi yog qhov hnav tsis kam kuaj cov qauv rau kev tsheb ciav hlau?
Rail ncoo hnav cov qauv ntsuas tsom rau cov khoom siv ua haujlwm ntev, muaj peev xwm thauj khoom, thiab ib puag ncig tiv thaiv, siv cov txheej txheem xws li kev ntsuam xyuas compression (ISO 1653, BS 903 C2), quasi-static / dynamic load-deflection, UV / kub aging, thiab abrasion cycles (Martindale) kom ntseeg tau tias kev pw tsaug zog 3 (piv txwv li, 0. kev ua tau zoo xav tau zoo li lub neej 8 xyoo, nrog rau cov kev cai tshwj xeeb sib txawv ntawm cov khoom siv (rubber, HDPE, composites) thiab huab cua.
Cov Qauv Tseem Ceeb & Kev Xeem:
- Compression Set: Kev ntsuas muaj peev xwm rov qab tau zoo tom qab thauj khoom ntev (piv txwv li ISO 1653, BS 903 C2), tseem ceeb heev rau kev tswj tsis tau.
- Load-Deflection: Tests load kis tau tus mob thiab nruj (piv txwv li, mus rau 250kN rau BR1213).
- Kev Ntsuas Dynamic: Rau cov khoom sib xyaw, kev ntsuas kev co dampening (xws li UIC 864-5 siv 5Hz).
- Environmental Resistance: UV raug (xws li, 1000h rau elasticity retention), kub heev, av noo, thiab khov -thaw cycles.
- Cov khoom siv -Specific: Martindale abrasion cycles (Ntau dua lossis sib npaug li 500,000 rau cov khoom sib xyaw), cov ntsiab lus tshwj xeeb, cov hmoov tshauv, thiab lwm yam.
- Kev Tiv Thaiv Hluav Taws Xob: Ua kom muaj rwb thaiv tsev (xws li ISO 2878).
Yam khoom twg yog qhov hnav tshaj plaws -tiv taus rau ib qho elastic rail ncoo?
Rau siab hnav tsis kam nyob rau hauv elastic rail pads, muaj zog hluavtaws roj hmab zoo li Nitrile Roj Hmab (NBR) thiab tshwj xeeb tebchaw xws li Sylodyn® HRB (high resistance blends) excel vim lawv durability, tsis kam rau cov roj / tshuaj, thiab muaj peev xwm lis hnyav loads thiab vibration, nrog rau cov ntaub ntawv xws li Natural Roj Hmab, SBR, thiab EPDM kuj muab kev ua tau zoo.
Yam Tseem Ceeb rau Hnav:
- Hnyav Loads: Cov ntaub ntawv yuav tsum tau rov qab siab dua thiab kev co tsis muaj deformation mus tas li.
- Environmental Factors: Resistance to heat, aging, chemicals, and moisture is tseem ceeb heev rau lub sij hawm ntev -kev ncaj ncees.
- Daim Ntawv Thov: Cov khoom siv zoo tshaj plaws nyob ntawm cov kev xav tau tshwj xeeb, los ntawm kev thauj mus los hauv nroog mus rau hnyav - tsheb ciav hlau.
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.
