Rail ncoo, yog cov roj hmab roj hmab ntawm lub tsheb ciav hlau khi phaj thiab ko taw ntawm txoj kev tsheb ciav hlau, ua los ntawm elastic polyurethane, uas yog interposed ntawm steel rails thiab sleepers kom txo tau kev sib txhuam thiab kev cuam tshuam. Rail pads yog fastened nyob rau hauv ib tug fastening system los ntawm cov ntsia hlau spikes los yog rail bolts rau hauv lub sleeper ties. Nws yog tsim los ua kom lub elasticity ntawm lub superstructure, txo kev poob siab thiab kev co nyob rau hauv lub rail system. Rail ncoo yog tsim los ntawm cov roj hmab los yog yas yog los dampen cov shocks thiab vibration effect rau lub tsheb ciav hlau thiab khiav. Feem ntau pib nrog kev teeb tsa qis qis txhawm rau ua kom lub caij nplooj ntoos hlav clip muaj qhov sib txawv loj dua, uas tuaj yeem lav lub tsheb ciav hlau tuav hauv kev sib cuag nrog cov tsheb ciav hlau, ua rau lub tsheb ciav hlau ua lub luag haujlwm zoo dua.
Yam khoom ntawm elastic rail ncoo yog hnav tshaj plaws -resistant?
Rau kev hnav zoo dua hauv cov ntaub qhwv elastic, Polyurethane (PU) feem ntau yog qhov kev xaiv sab saum toj, muab 3-5 zaug hnav zoo dua li roj hmab, tuav cov kev cuam tshuam loj, thiab kav ntev dua; Txawm li cas los xij, High-Density Polyethylene (HDPE) ua tau zoo nyob rau hauv hnyav heev, qis-ceev thauj khoom rau rigidity, thaum tshwj xeeb roj hmab tebchaw (xws li Nitrile) muab zoo durability, roj / aging kuj rau xav tau ib puag ncig.
Sab saum toj hnav- Cov Khoom Siv Ua Haujlwm:
- Polyurethane (PU): Txaus siab rau nws qhov tshwj xeeb ua haujlwm ntev, kev poob siab, thiab ua haujlwm rau qaug zog, PU cov ntaub qhwv tau zoo heev rau cov roj hmab, ua rau lawv zoo tagnrho rau kev siab - nrawm thiab hnyav- thauj lem xav tau lub neej ntev thiab kev ruaj ntseg.
- Nitrile Roj Hmab (NBR): Zoo heev rau cov xwm txheej hnyav, muab cov roj zoo, kev laus, thiab hnav tsis kam, haum rau cov cuab yeej nqa hnyav thiab kev sib tw kev lag luam.
