A rail ncoo, tseem hu ua rail roj hmab phaj, yog tsim los ntawm lub tsheb ciav hlau khi phaj thiab ko taw ntawm txoj kev tsheb ciav hlau, ua los ntawm elastic polyurethane lev, uas yog interposed ntawm steel rails thiab khi sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam. Nws txoj kev nruj nruj yog siv los ua kom lub elasticity ntawm lub superstructure ntawm lub ballast thiab txo kev poob siab thiab kev vibration hauv txoj kev tsheb ciav hlau.
Peb EVA / HDPE / roj hmab rail pads yog nrog siab elasticity, siv rau cov hom kev tsheb ciav hlau xws li rail UIC54, UIC60, BS80lbs, BS100lbs, thiab ntau thiab tsawg raws li tau txiav txim. Cov ntaub qhwv tuaj yeem hloov kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
Dab tsi yog cov txheej txheem xaiv rau kev tsheb ciav hlau?
Rail pad xaiv hinges ntawm load, ceev, thiab ib puag ncig, yuav tsum tau tshwj xeeb thickness (6-}20mm), hardness (nyob ib ncig ntawm 70 Shore A), thiab compatibility nrog rail hom thiab fastening system (piv txwv li, Pandrol, E-clip), nrog rau cov hom phiaj tseem ceeb yog kev co txo, suab nrov dampening, load tis, thiab taug qab kev ruaj ntseg, siv cov ntaub ntawv zoo li cov khoom siv roj hmab los yog roj hmab PE. cov qhov.
Yam Parameters:
- Thickness: 6mm (metro) txog 20mm + (siab-ceev/hnyav-haul).
- Hardness (Shore A): Nyob ib ncig ntawm 70 ± 5.
- Kev sib txhuam coefficient: Ntau dua lossis sib npaug rau 0.8 rau cov nkhaus nkhaus.

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.
