Kev ua hauj lwm hauv paus ntsiab lus ntawm railway pad
Rail pads ua haujlwm los ntawm kev ua lub hauv ncoo elastic ntawm txoj kev tsheb ciav hlau thiab kev pw tsaug zog (kuav), absorbing shocks, faib cov log loads nyob rau hauv ib cheeb tsam dav kom txo tau kev ntxhov siab, thiab damping vibrations, uas txo suab nrov, tiv thaiv hnav, tiv thaiv infrastructure, thiab txhim kho tag nrho cov kev ruaj ntseg thiab ntev. Lawv muab qhov tsis muaj, tiv thaiv cov hlau ncaj qha - ntawm - kev sib cuag ntawm cov pob zeb thiab ua kom lub cev muaj zog los ntawm kev txo qis thiab qaug zog.
Dab tsi yog qhov yuav tsum tau ua rau qaug zog tiv thaiv ntawm kev tsheb ciav hlau pads?
Rail ncoo qaug zog ua haujlwm yuav tsum tau hloov pauv cov cuab yeej tsawg (nruj, siab) tom qab ntau lab lub voj voog thauj khoom (xws li, 3 lab), qis compression teeb (xws li<15% for polyurethane), and no visible damage (cracks, perforation) to maintain vibration isolation, track stability, and long service life (10+ years) under high-speed train impacts, assessed via standards like EN 13146/17282 testing for material durability.
Cov Lus Qhia Tseem Ceeb & Kev Ntsuas:
- High Cycle Durability: Pads yuav tsum tau nyiaj ntau lab lub voj voog (piv txwv li, 3 lab) nrog kev degradation tsawg, sim los ntawm cov qauv xws li EN 13146-4+A1,.
- Stiffness & Load Transfer: Static thiab dynamic txaj modulus (stiffness) yuav tsum tsis txhob hloov pauv loj (xws li,<25%) after fatigue testing to ensure consistent vibration damping.
- Low Compression Set: Cov ntaub ntawv zoo li polyurethane yuav tsum muaj cov txheej txheem compression tsawg (xws li,<15%) after fatigue tests to retain their elastic properties.
- Visual Integrity: Tsis muaj qhov tawg, perforation, lossis kev puas tsuaj loj yuav tsum tshwm sim thaum kuaj, lees paub los ntawm kev kuaj pom.
- Material Properties: Must meet baseline specs like tensile strength (e.g., ≥19 MPa) and elongation (e.g., >80%).
- Environmental Resistance: Yuav tsum tswj kev ua haujlwm thoob plaws qhov kub thiab txias (kub / txias) thiab tiv thaiv kev laus / corrosion.
GNEE RAILmuab 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 rails xws li UIC54, UIC60, BS80lbs, BS100lbs, thiab lwm yam. Peb muaj ntau tshaj 130set 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.
