Dab tsi yog qhov txawv ntawm Rail Pads thiab Rail Tie Phaj?
A rail khi phajyog ib lub phaj steel uas fastens txoj kev tsheb ciav hlau mus rau txoj hlua khi, kom ntseeg tau tias qhov ntsuas tau raug thiab xa cov khoom thauj los ntawm kev tsheb ciav hlau mus rau txoj hlua khi. Arail ncooyog cov khoom siv elastic (xws li roj hmab lossis polyurethane) muab tso rau nruab nrab ntawm cov hlua khi thiab cov tsheb ciav hlau lossis cov neeg pw tsaug zog kom nqus cov kev poob siab thiab kev co thiab txo cov suab nrov. Rail pads feem ntau muab kev poob siab thiab kev xa khoom thauj khoom, thaum khi daim hlau feem ntau muab cov qauv kev sib txuas thiab ntsuas kev saib xyuas.
| Feature | Rail Tie Phaj | Rail Pad |
|---|---|---|
| Lub luag haujlwm tseem ceeb | - Txuas lub tsheb ciav hlau mus rau txoj hlua khi - Kho qhov ntsuas kev tsheb ciav hlau kom raug - Distributes load los ntawm txoj kev tsheb ciav hlau mus rau lub khi |
- Absorb shocks thiab vibration los ntawm cov tsheb ciav hlau hla - Dampens suab nrov - Tiv thaiv txoj hlua khi thiab hlua los ntawm hnav thiab cuam tshuam |
| Khoom siv | Hlau | Cov ntaub ntawv elastic xws li polyurethane lossis roj hmab |
| Qhov chaw | Nruab nrab ntawm lub steel rail thiab lub sleeper / khi | Nruab nrab ntawm txoj hlua khi thiab cov tsheb ciav hlau, lossis ncaj qha ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog |
| Cov txiaj ntsig ntxiv | - Tiv thaiv txoj kev tsheb ciav hlau los ntawm kev txav mus los - Muab qhov chaw ruaj khov, txawm tias cov kabmob nto |
- Ua kom cov neeg caij tsheb yooj yim dua - Txo cov load concentration - Seals tiv thaiv ya raws |
Hauv cov ntsiab lus:Lub tsheb ciav hlau khi phaj yog cov khoom siv hlau muaj zog uas muab kev sib txuas ntawm lub cev rau txoj kev tsheb ciav hlau, thaum lub tsheb ciav hlau yog ib qho kev poob siab -absorbing txheej uas txhim kho kev ua tau zoo thiab kev ua neej nyob ntawm tag nrho cov kev sib dhos los ntawm kev tswj cov kev ntxhov siab thiab kev vibrations los ntawm cov tsheb ciav hlau.
Lub rail ncoo nteg nyob rau hauv lub tsheb ciav hlau yog siv los lav
- Lub load faib npog thaj tsam loj dua
- Txo cov load concentration thiab kev siv qaug zog kev nyuaj siab
- Txawm thaj chaw sib cuag ntawm txoj kev tsheb ciav hlau thiab cov khoom txhawb nqa
- Txo cov suab nrov thiab cov qauv kev co
- Sealing muaj nuj nqi ntawm kev txhawb nqa sab saum toj thiab kev tsheb nqaj hlau hauv qab
- Txo cov tsheb ciav hlau hnav thiab cuam tshuam cov khoom txhawb nqa
Rail Pad Khoom
Rail pads yog tsim los ntawm ntau yam khoom siv, suav nrog ntau hom roj hmab (natural rubber, SBR, EPDM) thiab cov yas zoo li HDPE thiab EVA. Lwm cov ntaub ntawv muaj xws li thermoplastic elastomers (TPV), polyurethane, thiab ntau yam kev sib xyaw ua ke los muab cov cushioning, vibration dampening, thiab hluav taws xob rwb thaiv tsev ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog.

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.
