Railway taug tshooj (Rails) yog cov khoom sib xyaw tseem ceeb tso nruab nrab ntawm cov nqaj hlau thiab cov pw tsaug zog, nqus shopps, thiab tiv thaiv ob qho tib si ntawm cov pw tsaug zog thiab ntsia.
Cov kev ua haujlwm ntawm kev tsheb nqaj hlau
- Ua ntej, Rail pads zoo nqus qhov kev cuam tshuam thiab kev co los ntawm kev sim kev tsheb ciav hlau, tsis muaj kev ntxhov siab ncaj qha rau kev sib tw ntawm cov kev pab cuam ntawm cov txheej txheem.
- Thib ob, Rail pads txhim kho raws kev ruaj khov, minimizing micro {{0} Kev taw qhia ntawm kev tsheb ciav hlau thiab pw tsaug zog, ua haujlwm kom muaj kev nyab xeeb thiab du.
- Ntxiv rau, Cov ntaub qhwv cov suab nrov muab cov suab nrov sib cais, txo cov suab nrov thiab txhim kho ib puag ncig raws txoj kev, tshwj xeeb yog ib qho tseem ceeb rau cov hauv nroog hla kev.
Rail ntaub qhwv tseem tiv thaiv kev tiv thaiv corrosion thiab hnav, kev tiv thaiv pw tsaug zog thiab txo cov nqi kho thiab cov nqi.
Nyob ntawm cov khoom siv, cov ntaub qhwv cov ntaub qhwv muab cov yam ntxwv sib txawv. Roj hmab cov ntaub qhwv muab elasticity zoo thiab lub ncoo, EVA cov ntaub ntawv yog qhov nyuaj thiab haum rau high {1} log lem.
