Dab tsi yog cov qauv sib txawv rau Rail Pads?
Rail ncooCov qauv sib txawv raws cheeb tsam thiab hom kev thov, nrog rau cov qauv xws li European EN 13481-2 thiab EN 16730, Suav TB / T2626, thiab Indian RDSO specifications. Lwm cov qauv uas tau hais tseg yog ua raws li cov koom haum kev tsheb ciav hlau hauv cheeb tsam xws li UIC, thiab cov kev tswj hwm kev tswj hwm zoo xws li ISO 9001 thiab ISO 14001 kuj tseem siv tau ntawv pov thawj. Cov qauv hais txog cov khoom siv, qhov ntev, thiab cov yam ntxwv ua haujlwm zoo li elasticity thiab qaug zog ua haujlwm.

Cov ntsiab lus tseem ceeb suav nrog cov qauv
- Khoom muaj pes tsawg leeg:Cov qauv qhia tias cov ntaub qhwv yuav tsum yog ua los ntawm cov ntaub ntawv nkauj xwb zoo li cov roj hmab ntuj (RSS qib 1-4) lossis sib xyaw nrog lwm cov roj hmab hluavtaws, thiab txwv tsis pub siv cov roj hmab rov qab los yog rov ua dua tshiab.

- Cov qauv kev ua haujlwm:Specifications feem ntau hais txog yam xws li:
Elasticity:Txhais los ntawm ib qho elastic coefficient, feem ntau muab raws li qhov ntau hauv MPa lossis N / mm², ob qho tib si ua ntej thiab tom qab kev laus.
Fatigue resistance:Muaj peev xwm tiv taus kev ntxhov siab dua yam tsis muaj kev tawg lossis puas tsuaj.
Compression set:Ib qho kev ntsuas ntawm qhov deformation mus tas li tom qab compressed.
Roj kuj:Kev tiv thaiv kev hloov pauv hauv huab hwm coj thiab cov tsos thaum raug cov roj.
- Zoo thiab zoo:Cov qauv muaj xws li qhov yuav tsum tau ua rau lub ntsej muag du, cov npoo zoo nkauj, thiab cov kev txwv ntawm qhov tsis xws luag xws li cov ces kaum uas ploj lawm, impurities, thiab burrs.
- Thickness:Txawm tias tsis yog ib txwm "tus qauv," thickness yog teev raws li daim ntawv thov. Piv txwv li, cov ntaub qhwv rau cov tsheb ciav hlau ceev feem ntau yog 8-12 hli tuab, thaum cov khoom thauj hnyav yog 12-20 hli tuab. Cov ntaub qhwv nyias nyias yog tsim rau cov tsheb ciav hlau hauv nroog, thiab cov ntaub qhwv tuab yuav xav tau rau huab cua huab cua.
- Kev tswj kom zoo:Ntau lub tuam txhab ua raws li kev tswj hwm kev lag luam zoo xws li ISO 9001 thiab ISO 14001 rau kev tswj hwm ntau lawm.
Dab tsi Rail Pads yog thiab lawv lub hom phiaj?
Rail Pads yog nyias, muaj zog txheej. Lawv tau tsim los ntawm cov khoom xws li roj hmab lossis cov khoom sib xyaw tshwj xeeb. Lawv zaum ntawm lub tsheb ciav hlau hauv qab thiab lub sleeper. Lawv lub luag haujlwm tseem ceeb yog:
- So kom co co los ntawm tsiv tsheb ciav hlau.
- Nres cov hlua thiab cov neeg pw tsaug zog tsis txhob hnav sai.
- Ua kom txoj kev ruaj khov thiab muaj zog.
Yog tsis muaj Rail Pads, lem tau ntxhov siab. Qhov no ua rau muaj kev puas tsuaj sai thiab kho nqi kim.
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. Peb cov EVA / HDPE / roj hmab rail pads yog nrog siab elasticity, thov rau hom kev tsheb ciav hlau xws li tsheb ciav hlau UIC54, UIC60, BS80lbs, BS100lbs, thiab ntau thiab tsawg raws li tau txiav txim. Cov ntaub qhwv tuaj yeem kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
