Cov ntaub ntawv twg ntawm kev tsheb ciav hlau muaj tus nqi zoo tshaj -kev ua tau zoo?
Dec 19, 2025
A rail ncoo, tseem hu ua rail roj hmab phaj, feem ntau yog siv ntawm khi daim hlau thiab cov neeg pw tsaug zog lossis nruab nrab ntawm cov ntsia hlau thiab khi phaj. Lub rail ncoo yog ua los ntawm elastic polyurethane lev thiab feem ntau yog siv rau cov pob zeb pw tsaug zog. Lub rail ncoo tuaj yeem tiv thaiv lub pob zeb pw tsaug zog los ntawm kev puas tsuaj thiab kev cuam tshuam, thiab nws tuaj yeem txo qhov kev vibration ntawm lub tsheb ciav hlau hla.
Cov ntaub ntawv twg ntawm kev tsheb ciav hlau muaj tus nqi zoo tshaj -kev ua tau zoo?
Rau qhov zoo tshaj plaws tag nrho tus nqi -effectiveness,roj hmab (tshwj xeeb yog SBR lossis cov pos hniav ntuj)thiabEVA (Ethylene{0}}Vinyl Acetate)yog cov neeg sib tw sab saum toj, muab cov khoom siv qis qis qis, kev co zoo dampening, thiab lub neej ua haujlwm ntev hauv cov huab cua nruab nrab, txawm tias siab -kev ua tau zoopolyurethanetej zaum yuav pheej yig dua ntev -lub sij hawm nyob rau hauv hnyav- tsheb thauj mus los lossis huab cua hnyav vim muaj kev ruaj khov zoo dua thiab txo kev txij nkawm, ntsuas tus nqi pib nrog kev txuag lub neej.

Dab tsi yog qhov zoo ntawm kev siv roj hmab los tsim cov ntaub thaiv npog?
Siv cov roj hmab rau cov ntaub thaiv kev tsheb ciav hlau muaj cov txiaj ntsig zoo xws li kev vibration / suab nrov txo, txuas ntxiv lub neej los ntawm kev cuam tshuam kev nqus, txhim kho neeg nrog kev nplij siab, hluav taws xob rwb thaiv tsev, thiab kav ntev tiv thaiv huab cua / tshuaj lom neeg, ua rau qis dua - lub sij hawm tu cov nqi thiab kev ruaj ntseg zoo dua piv rau lwm txoj hauv kev, ua rau lawv raug nqi - zoo thiab ruaj khov.
Dab tsi yog qhov zoo ntawm kev siv eva los tsim cov tsheb ciav hlau?
Siv EVA (Ethylene Vinyl Acetate) rau rail pads muaj qhov tseem ceeb zoo li zoo heevcushioning thiab vibration damping, txo cov suab nrov thiab ncua lub neej khiav, nrog rau qhov zoohuab cua / tshuaj tiv thaiv, hluav taws xob rwb thaiv tsev, thiab tus nqi zoo- qhov txiaj ntsig piv, ua rau nws zoo tagnrho rau kev thauj mus los hauv nroog thiab nruab nrab- cov kab nrawm uas xav tau kev ua haujlwm ntev yam tsis muaj siab - cov nqi roj hmab kawg.
Peb cov EVA / HDPE / roj hmab rail pads yog nrog siab elasticity, thov rau hom kev tsheb ciav hlau xws li tsheb ciav hlau UIC54, UIC60, BS80lbs, BS100lbs, thiab ntau thiab tsawg raws li tau txiav txim. Cov ntaub qhwv tuaj yeem raug kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
