Rail Padyog ib qho kev tivthaiv uas ua haujlwm hauv kev sib koom tes nrog lwm qhov chaw fastening. Nws yuav tsum tau siv ua ke nrog rails, sleepers, rail clips, insulated gauge blocks, thiab lwm yam., los tsim ib tug ua tiav txoj kev fastening thiab cushioning system. Kev xaiv ntawm cov ntaub qhwv lub thickness yuav tsum ua raws li cov kev cai elastic ntawm tus qauv tsim, ua kom tiav cov clamping quab yuam ntawm txoj kev tsheb ciav hlau. Qhov no ua kom ruaj khov rail fixation thaum tso cai rau kev hloov kho qhov siab qhov sib txawv los ntawm nws tus kheej elasticity, ua rau nws yog ib qho tseem ceeb pab tivthaiv rau kev tswj cov geometry.
Yuav ua li cas xaiv rail pads rau cov cheeb tsam txias heev?
Rau cov cheeb tsam txias heev, xaiv cov tsheb ciav hlau nrog qis dua -kub elasticity, tshwj xeeb yog cov ntaub ntawv xws li polyurethane (PU) lossis hydrogenated nitrile roj hmab (HNBR), uas tiv taus tawv thiab tawg hauv qab -40 degree, tsis zoo li cov roj hmab txheem uas embrittles; xyuas kom cov pawm ua tau raws li qhov qis- qhov kub thiab txias (xws li Tsawg dua lossis sib npaug ntawm -40 degree), siab elastic rov qab (Ntau dua lossis sib npaug li 75% ntawm -30 degree), thiab hnav tsis kam, dhau kev sim qaug zog rau lub voj voog khov-thaw kom tswj tau cushioning thiab taug qab kev nyab xeeb.
Cov ntsiab lus tseem ceeb ntawm cov khoom siv:
- Polyurethane (PU) Pads: Kev xaiv zoo tshaj plaws rau thaj chaw alpine / txias, tswj kev ua haujlwm mus txog -40 degree.
- Hydrogenated Nitrile Rubber (HNBR) Pads: Ua kom txias txias, nrog cov ntsiab lus nkig tsawg li -55℃thiab siab elasticity tuav.
- Zam Tsis Siv Neeg Roj Hmab: Ua rau tawv tawv, tawg, thiab poob ntawm elasticity thaum txias txias.
Qhov tseem ceeb Performance Metrics:
- Tsawg-Temperature Brittle Point: Yuav tsum qis (piv txwv li, Tsawg dua lossis sib npaug li -40 degree) txhawm rau tiv thaiv kev tawg thaum txias heev.
- Elastic Recovery Rate: Kev rov zoo siab (piv txwv li, Ntau dua lossis sib npaug li 75% ntawm -30 degree) ua kom cov cushioning tseem zoo.
- Txias-Thaw Resistance: Nws yog ib qho tseem ceeb kom tiv thaiv rov qab khov thiab thawing yam tsis muaj kev puas tsuaj.
- Hnav Resistance: Tsawg hnav tus nqi (xws li, Tsawg dua lossis sib npaug li 0.5mm / xyoo) ua rau muaj kev sib txhuam los ntawm cov daus / dej khov.
