Yuav ua li cas yog corrosion kuj ntawm Rail Pads?
Rail padsmuaj kev tiv thaiv corrosion zoo, tshwj xeeb tshaj yog cov khoom tsim los ntawm cov khoom zoo li siab -cov khoom siv polymers thiab qee cov hlau, uas tuaj yeem tiv taus ib puag ncig hnyav, nrog rau cov dej noo, ntsev, thiab kub hloov pauv. Cov kev tshawb fawb tau pom tias cov rail pads ntsia rau hauv qhov kev txhim kho ncaj qha tsis cuam tshuam los ntawm corrosion lossis ib puag ncig yam. Corrosion kuj tuaj yeem txhim kho ntxiv los ntawm cov ntaub qhwv cov khoom, tsim, thiab cov txheej txheem tiv thaiv.
Cov yam ntxwv cuam tshuam rau corrosion kuj
- Khoom siv:Qee cov ntaub ntawv, xws li cov khoom siv siab tshaj -cov khoom siv polymers thiab hlau, yog qhov muaj peev xwm tiv taus corrosion.

- Environmental tej yam kev mob:Txawm hais tias qee cov ntaub ntawv tuaj yeem ua rau muaj kev phom sij, ntau lub tsheb ciav hlau tau tsim los tiv thaiv ntau yam ntawm ib puag ncig, nrog rau cov dej noo, tshuaj lom neeg, thiab qhov kub thiab txias.
- Tsim:Hlau cushion pads, piv txwv li, tuaj yeem tsim nrog cov qauv ntxeem tau thiab kev ua haujlwm elastic uas ua rau lawv zoo heev rau cov neeg kho tshuab thiab ib puag ncig kev ntxhov siab, nrog rau kev xeb.
- Txheej:Cov txheej txheem tiv thaiv thiab lwm yam corrosion-cov kev kho mob tuaj yeem siv rau cov ntaub thaiv kev tsheb ciav hlau thiab lawv cov khoom cuam tshuam, xws li cov clips thiab cov phaj ib leeg, txhawm rau txhim kho lawv lub neej ntev.
- Kev tu:Kev txhim kho kom zoo thiab kev saib xyuas kev coj ua kuj tseem ceeb heev rau kev ua kom muaj kev tiv thaiv corrosion thiab lub neej ntev ntawm cov tsheb ciav hlau.
Kev ua haujlwm ntawm Rail Pads hauv Railway Systems
- Kev vibration txo thiab suab nrov txo
Ib qho ntawm cov haujlwm tseem ceeb ntawm cov tsheb ciav hlau yog qhov txo qis ntawm kev vibrations thiab suab nrov tsim los ntawm cov tsheb ciav hlau. Thaum lub tsheb ciav hlau hla cov ntu tsis sib xws, qhov ua rau muaj kev vibrations tuaj yeem ua rau tsis xis nyob rau cov neeg caij tsheb thiab tuaj yeem ua rau muaj kev puas tsuaj ntawm cov qauv khiav mus rau lub sijhawm. Rail pads zoo nqus cov kev vibrations, muab lub caij ntsiag to thiab txuas ntxiv lub neej ntawm ob qho tib si lem thiab cov qauv uas nyob ib sab.
- Load Distribution thiab Impact Absorption
Rail pads ua haujlwm los faib cov khoom hnyav los ntawm lub tsheb ciav hlau lub log hla thaj tsam loj dua ntawm cov neeg pw hauv qab. Qhov no tsis tsuas yog pab txo qis kev ntxhov siab hauv cheeb tsam tab sis tseem cuam tshuam qhov deformation ntawm txoj kev tsheb ciav hlau. Lawv muab cov nyhuv cushioning tseem ceeb uas nqus cov kev cuam tshuam, kom ntseeg tau tias cov kab khiav thiab cov pw tsaug zog nyob twj ywm zoo, thiab pab txhawb kev nyab xeeb thiab txhim khu kev qha tsheb ciav hlau.
- Txhim kho Track Stability thiab Longevity
Kev teeb tsa ntawm siab -cov ntaub ntawv tsheb ciav hlau zoo ua rau muaj txiaj ntsig zoo rau tag nrho kev ruaj ntseg thiab kev ua haujlwm ntev ntawm kev tsheb ciav hlau. Los ntawm kev ruaj ntseg tuav txoj kev tsheb ciav hlau nyob rau hauv qhov chaw, lawv tiv thaiv kev txav mus los, yog li txo qis cov teeb meem tsis zoo uas tuaj yeem tshwm sim los ntawm kev tsheb lossis kev cuam tshuam ib puag ncig. Tsis tas li ntawd, cov khoom xws li cov los ntawm GNEE raug tsim los ua raws li cov qauv nruj hauv teb chaws thiab thoob ntiaj teb, kom ntseeg tau tias txoj kev tsheb ciav hlau muaj kev ua haujlwm zoo thiab kev nyab xeeb nyob rau lub sijhawm.
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 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 kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
