Rail padsyog siab -cov khoom ua tau zoo nruab nrab ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog uas ua haujlwm rau ntau yam haujlwm tseem ceeb. Lawv tau tsim los txo cov kev ntxhov siab los ntawm cov tsheb ciav hlau mus ncig ntawm ntau qhov nrawm thaum ua kom ntseeg tau tias kev sib tw khiav tau zoo. Ua los ntawm ntau yam ntaub ntawv, rail pads yog engineered los tiv thaiv hnyav loads thiab txawv ib puag ncig tej yam kev mob, ua rau lawv ib tug tseem ceeb nam ntawm kev tsheb ciav hlau tu.
Cov ntaub ntawv dab tsi yog rail elastic pads ua los ntawm?
Rail elastic pads yog tsim los ntawm ntau yam resilient, tsis yog-cov ntaub ntawv hlau zoo li cov roj hmab ntuj, hluavtaws roj hmab (SBR, Neoprene, EPDM), thiab siab- cov yas ua tau zoo xws li HDPE (High-Density Polyethylene), EVA (Ethylene-Vinylene, TPU, Acetate), qee zaum sib xyaw nrog micro-cov ntaub ntawv ua npuas ncauj lossis cov khoom sib xyaw, txhua tus xaiv rau lawv qhov kev poob siab, ua haujlwm ntev, thiab ua haujlwm rau kev vibration thiab kub heev.
Cov khoom siv siv:
- Roj Hmab: Feem ntau cov roj hmab ntuj lossis hluavtaws sib xyaw (Styrene-Butadiene Roj Hmab - SBR, Chloroprene) rau elasticity zoo heev, tiv thaiv - vibration, thiab hnav tsis kam.
