Rail padsyog cov elastic polyurethane mats uas yog cuam tshuam ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
Ntau yam ntawm -kev ua tau zoo elastic rail pads tau tsim rau cov kev xav tau nruj thiab ntau yam kev thov hauv cheeb tsam- los ntawm cov tsheb ciav hlau los ntawm cov qauv ntsuas kev tsheb ciav hlau mus rau cov kab hnyav hnyav, qhov no tshwj xeeb tshaj yog tsim rau E- hom tsheb ciav hlau fastening systems thiab SKL- hom kev tsheb ciav hlau fastening system nrog cov khoom siv ntawm HDPE/EVA/R.

Kev xaiv cov khoom siv rau kev tsheb ciav hlau: Qhov twg zoo dua, polyurethane lossis roj hmab?
Rau cov ntaub thaiv kev tsheb ciav hlau, Polyurethane (PU) feem ntau zoo dua rau cov roj hmab rau siab - kev ua tau zoo, ntev- cov ntawv thov vim nws qhov kev hnav zoo heev, muaj peev xwm thauj khoom ntau dua, thiab kev ua haujlwm zoo dua rau cov roj / ozone, thaum cov roj hmab excels hauv tus nqi pib thiab cov suab nrov / kev vibration dampening, ua rau nws zoo rau kev siv; PU muab cov txiaj ntsig zoo dua ntev dua -lub sijhawm txawm tias tus nqi siab dua.
Polyurethane Advantages (PU):
- Durability: Ua kom zoo dua qub (3-5x roj hmab) thiab tiv taus roj, roj, ozone, thiab UV.
- Load Bearing: Lub zog ntau dua, tsis tshua muaj siab rau deflection, thiab tswj cov khoom hauv qab hnyav, rov ua dua.
- Lub neej ntev: Lub neej ua haujlwm ntev dua (8-10 xyoo vs. 5-6 rau roj hmab), txo qhov hloov zaus thiab cov nqi mus sij hawm ntev.
- Kev ua tau zoo: Muab kev txhawb nqa ruaj khov thiab kev vibration buffering, zoo tagnrho rau siab -ceev thiab hnyav- cov kab.
Roj hmab qhov zoo:
- Kev vibration / suab nrov: Zoo dua ntawm kev ua kom muaj kev vibrations thiab suppressing suab nrov.
- Nqe: Tus nqi pib yuav qis dua.
- Flexibility: Tej yam yooj yim yuav muab tau zoo pib cuam tshuam kuj.
Thaum xaiv qhov twg:
- Xaiv PU rau: Siab- tsheb ciav hlau ceev, hnyav- cov kab tsheb thauj mus los, huab cua huab cua, kev txuag nyiaj ntev, lossis qhov xav tau roj / tshuaj tiv thaiv.
- Xaiv Roj Hmab rau: qis dua - cov kab nrawm, cov ntawv thov dav dav uas tus nqi pib yog thawj zaug, lossis qhov twg lub suab nrov tshaj plaws yog qhov tseem ceeb.
Dab tsi yog kev siv ntawm ib qho elastic rail ncoo?
Elastic rail pads yog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau nyob nruab nrab ntawm txoj kev tsheb ciav hlau thiab pw tsaug zog (khi) rautxo kev vibration, suab nrov, thiab cuam tshuam, faib log loads, tiv thaiv kev puas tsuaj, thiab muabhluav taws xob rwb thaiv tsev, ua kom lub neej ntev ntawm cov qauv khiav, txo kev txij nkawm, thiab txhim kho cov neeg caij tsheb kev nplij siab los ntawm absorbing shocks thiab damping rail txav.
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.
