Rail padsyog elastic polyurethane mats uas yog interposed ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
Dab tsi yog hom kev tsheb ciav hlau sib txawv?
Railroad pads yog categorized los ntawmkhoom(Rubber, HDPE, EVA, TPEE, Composite/Polyurethane) thiabtsim / muaj nuj nqi(Grooved, Nruam, Discontinuous, Rectangular, Trapezoidal, Clip-On/Bolt-On rau cov tshuab hnyav) kom nqus tau qhov cuam tshuam, txo kev vibration, tiv thaiv kev puas tsuaj rau cov neeg pw tsaug zog, thiab ua kom muaj kev sib txhuam, nrog rau cov hom tshwj xeeb rau siab -ceev, hnyav- tsheb thauj mus los, lossis kev siv crane.

Yuav ua li cas yog tus tsim ntawm rail pads txawv rau cov hloov seem?
Rail pads rau hloov seem (turnouts) txawv los ntawm kev xav tau ntau dua durability, tshwj xeeb cov duab (xws li studded los yog grooved) rau complex load paths, thiab feem ntau composite cov ntaub ntawv (dual polymer) los tuav dynamic zog, suab nrov, thiab puas ntawm cov qav thiab hla, muab ib qho tseem ceeb poob siab absorbing qhov twg tangles tsis zoo li geometry.
Qhov Tseem Ceeb Tsim Qhov Sib txawv rau Hloov Rail Pads:
Geometry & Structure:
- Studded / Grooved Designs: Feem ntau rau cov keyboards, cov no txhim khu kev tuav, tiv thaiv zawv zawg (sab laug txav), thiab txhim kho kev faib khoom hauv cov chaw pivot.
- Complex Shapes: Cov ntaub qhwv yuav tsum ua raws li qhov tshwj xeeb, feem ntau tsis yog - cov cheeb tsam ib puag ncig ntawm Qav (qhov chaw sib tw sib ntsib) thiab hloov cov hniav, xav tau kev cai- pwm lossis qauv tsim.
Khoom siv & kev ua haujlwm:
- High Resilience Elastomers: Ntuj los yog hluavtaws roj hmab nrog siab elasticity kom nqus cov kev cuam tshuam thiab kev vibrations los ntawm cov log hla qhov khoob thiab cov kaum sab xis.
- Dual-Polymer Composites: Kev sib xyaw cov polymers rau lub zog zoo dua, tiv thaiv kev puas tsuaj, thiab txuas ntxiv lub neej nyob rau hauv siab - thaj chaw muaj kev ntxhov siab ntawm kev hloov.
- Suab nrov & kev vibration Damping: Qhov tseem ceeb vim lub suab nrov ntawm cov log hla dhau qhov sib txawv ntawm Qav, ua kom nrov nrov yog lub hom phiaj tseem ceeb tsim.
Load Management:
- Extreme Load Distribution: Switches concentrate heavy rog; pads yuav tsum kis tau cov loads zoo los tiv thaiv cov neeg pw tsaug zog (kev sib txuas) thiab ballast los ntawm kev puas tsuaj sai.
- Impact Attenuation: Qhov tseem ceeb ntawm Qav, qhov twg lub log hloov ntawm ib qho kev tsheb ciav hlau mus rau lwm qhov, yuav tsum muaj kev poob siab tshaj plaws.
Yuav ua li cas xaiv txoj kev tsheb ciav hlau ncoo?
Kev xaiv txoj kev tsheb ciav hlau yuav tsum sib piv nws cov khoom siv, thickness, thiab hardness rau koj txoj kev cov kev xav tau tshwj xeeb: siab - cov kab ceev xav tau cov polyurethane txhav rau kev ruaj ntseg, hnyav- thauj khoom thauj khoom xav tau cov roj hmab ntxiv rau lub zog, cov kab hauv nroog yuav siv cov ntaub mos muag rau lub suab nrov, thiab txhua daim ntawv thov yuav tsum xav txog kev thauj khoom, kev ceev, kub, thiab kev tiv thaiv kev tiv thaiv.
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.
