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.
Tus nqi zoo li qub ntawm kev tsheb ciav hlau txhais li cas?
Railroad pad static stiffness yog txhais raws li qhov piv ntawm ib tug maj mam siv ntsug load rau qhov tshwm sim deflection, feem ntau ntsuas nyob rau hauv kiloNewtons ib millimeter (kN/mm) thiab xam los ntawm txoj kab nqes ntawm lub quab yuam-deflection nkhaus nyob rau hauv lub elastic cheeb tsam, sawv cev rau lub ncoo tiv thaiv deformation nyob rau hauv sustaining vibration load. Nws txheeb xyuas qhov yuav tsum tau muaj zog npaum li cas kom ua tiav qhov kev txav ntsug tshwj xeeb, nrog cov txiaj ntsig siab dua qhia tias muaj kev nruj dua rau kev thauj khoom hnyav, thiab qis dua qhov tseem ceeb muab softness rau siab - tsheb ciav hlau ceev.
Factors Influencing Stiffness:
Khoom siv: Cov polymers sib txawv (EPDM, EVA, TPE) muaj qhov sib txawv ntawm qhov sib txawv.
| Raw Khoom | Rubber, EVA, TPEE, HDPE |
| Txuj | UIC, AREMA, TB/T2626-95 |
| Daim ntawv thov | 43kg / m, 50kg / m, 60kg / m, 75kg / m, 115RE, UIC54, UIC60, S49 |

| Sau ntawv | Lawv yuav tsum tau muab khaws cia rau hauv qhov chaw huv, qhov cua. Tsis txhob nyob hauv tshav ntuj ncaj qha, thiab kom deb ntawm qhov chaw tshav kub thiab tshuaj reagent. Tsis txhob kov cov roj, cov kuab tshuaj organic, thiab lwm yam tshuaj. Txwv tsis pub raug. |
Kub: Cov tawv nqaij feem ntau txo qis nrog qhov kub thiab txias.
Thickness: Thicker pads yog softer (tsawg zog).
Toe Load: Nce clamping quab yuam (ntiv taw load) ua kom nruj.
Dab tsi yog qhov sib txawv ntawm qhov tawv nqaij ntawm rail elastic pads ua los ntawm cov khoom sib txawv?
Rail ncoo txhav txawv txav los ntawm cov khoom siv, nrog EVA feem ntau yog qhov tawv tshaj, ua raws li TPE (Thermoplastic Elastomer) (nruab nrab), thiab EPDM (Ethylene Propylene Diene Monomer) (softest) ntawm chav tsev kub; pads stiffer (zoo li EVA) txo kev vibration tab sis nce ballast hnav, thaum softer pads (xws li EPDM / roj hmab) muab kev co zoo dua kev sib cais tab sis tuaj yeem ua rau muaj kev puas tsuaj ntau dua, nrog kev nruj kuj hloov nrog kub, load, thiab ncoo thickness.
GNEE RAIL muab tshwj xeeb elastic rail pads ntawm ntau hom rau siab - kev tsheb ciav hlau ceev, ib txwm - kev tsheb ciav hlau ceev, thiab cranes. Tshwj xeeb tshaj yog cov rail pads ua los ntawm roj hmab, EVA, TPEE, thiab HDPE yog heev nrov nrog cov neeg muas zaub. Peb cov railway roj hmab pads haum rau cov ntsia hlau xws li UIC54, UIC60, BS80lbs, BS100lbs, thiab lwm yam. Peb muaj ntau tshaj 130sets ntawm cov cav tov nyob rau hauv peb cov kab ntau lawm uas muaj peev xwm ncav cuag ib xyoos twg muaj peev xwm mus txog 2000, 000 daim ntawm rail pads. Peb muab ntau hom kev tsheb ciav hlau thiab lwm cov ntaub ntawv taug qab ntawm tus nqi sib tw.
