A rail ncooyog muab tso rau hauv nruab nrab ntawm lub tsheb ciav hlau thiab baseplate los yog sleeper. Rail ncoo yog qhia rau txoj kev tsheb ciav hlau fastening system vim nws cov resilience los yog viscoelasticity uas yuav siv tau nyob rau hauv kev cuam tshuam ntawm qaug zog cracking ntawm pw tsaug zog. Lub dynamic kev ntxhov siab los ntawm lub log los yog kev tsheb nqaj hlau cuam tshuam los ntawm ob qho tib si tsis tu ncua thiab tsis xwm yeem txav yog attenuated.

Lub luag haujlwm ntawm railway pads hauv railways
Railway pads yog elastic mats muab tso rau nruab nrab ntawm txoj hlua thiab cov neeg pw tsaug zog (kev sib txuas) kom nqus tau cov kev poob siab, txo kev vibration thiab suab nrov, faib cov log loads nyob rau hauv ib cheeb tsam loj, thiab tiv thaiv cov khoom siv taug qab los ntawm kev hnav, ua rau muaj kev cuam tshuam loj rau kev ua neej nyob thiab txhim kho cov neeg caij tsheb los ntawm kev cuam tshuam cushioning thiab tiv thaiv kev pw tsaug zog. Lawv kuj muab hluav taws xob rwb thaiv tsev, tiv thaiv cov teeb liab, thiab txhim kho kev ruaj ntseg tag nrho.

Dab tsi ua rau rail elastic pad aging?
Rail elastic ncoo aging yog tshwm sim los ntawm txhua yam kev ntxhov siab (kev cuam tshuam, kev vibrations, lub log loads), ib puag ncig yam (UV, huab cua txias, noo noo), thiab tshuaj lom neeg raug (hydrocarbons los ntawm lubricants), ua rau muaj zog hardening, tawg, khoom poob, thiab txo elasticity, uas cuam tshuam kev co dampening thiab taug qab kev nyab xeeb.
Tseem ceeb Aging Factors:
- Mechanical Loading: Tsis tu ncua siab - siv zog cuam tshuam los ntawm lub log flats, rail defects, hnyav qag loads, thiab vibrations maj mam deteriorate lub ncoo tus qauv, ua rau nws nruj thiab txo nws cushioning peev xwm nyob rau hauv lub sij hawm.
- Kub kub heev: Cov kub qis heev ua rau tawv tawv thiab brittleness, ua rau cov ntaub qhwv tuaj yeem tawg, thaum kub kub tuaj yeem ua kom degradation.
- UV Radiation: Hnub ci raug tuaj yeem txo qhov tawv tawv thiab ua rau tsis zoo rau cov khoom siv, tshwj xeeb tshaj yog nyob rau hauv qis dua.
- Chemical Contamination: Hydrocarbons (roj, lubricants) tuaj yeem ua rau cov khoom o lossis tawv hloov, nyob ntawm cov ntaub qhwv cov ntaub ntawv polymer (EPDM, EVA).
- Moisture & Dirt Traping: Npog ntawm lub ncoo thiab kev tsheb ciav hlau / pw tsaug zog ntxiab dej thiab plua plav, ua kom muaj zog corrosion thiab cov khoom tawg, thiab ua kom muaj zog.
Raws li ib tug kws tshaj lij rail fastener chaw tsim tshuaj paus, GNEE RAIL tuaj 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.
