Cov ntaub ntawv dab tsi yog rail pads ua los ntawm?
Rail padsyog tsim los ntawm ntau yam ntaub ntawv elastic thiab yas xws li roj hmab (natural, SBR, Neoprene), HDPE (High-Density Polyethylene), EVA (Ethylene-Vinyl Acetate), thiab cov khoom zoo xws li cov thermoplastic elastomers (TPE/TPV), xaiv rau lawv lub peev xwm los nqus kev poob siab, tsis muaj suab nrov, kev co thiab kev co. pw tsaug zog / ballast, ncua kev taug qab lub neej.
Khoom siv:
- Roj hmab:Ntuj roj hmab, Styrene-Butadiene Roj Hmab (SBR), Chloroprene (Neoprene) muab siab elasticity, resilience, thiab tsis kam hnav, zoo tagnrho rau kev poob siab.

- TPV (Thermoplastic Vulcanizate) & TPEE:Micro-foamed lossis dynamic vulcanizate hom muaj kev ua haujlwm zoo heev, ua haujlwm ntev, thiab hloov tau yooj yim.
- Nylon (PA6):Siv rau nws cov neeg kho tshuab siab zog thiab hnav tsis kam hauv qee qhov kev siv.
Rail pad muaj nuj nqi
Rail roj hmab ncoo yog qhov tseem ceeb hauv kev txo qis kev poob siab thiab kev co hauv lub tsheb ciav hlau. Lub ncoo nteg nyob rau hauv lub tsheb ciav hlau los xyuas kom meej:
Load faib tshaj qhov loj dua
Tshem tawm ntawm load concentration thiab ua rau qaug zog stresses
Centering ntawm loads ntawm cov khoom txhawb nqa
Kev nqus ntawm qhov tsis sib xws ntawm qhov chaw sib txuas ntawm kev tsheb nqaj hlau thiab kev txhawb nqa
Txo cov suab nrov thiab kev vibration
Kev sib khi ntawm lub hauv qab ntawm txoj kev tsheb ciav hlau thiab sab saum toj ntawm kev txhawb nqa
Kev txo qis ntawm kev hnav ntawm txoj kev tsheb ciav hlau thiab nws txoj kev txhawb nqa
GNEE RAILequips 130sets machine 'rail pad ntau lawm kab, rau kev ua, txhaj tshuaj, refining roj hmab, sulfuration, molding thiab soj ntsuam thiab lwm yam. Peb muaj peb tus kheej rail pad txhim kho engineers, tsim, tsim thiab tshuaj xyuas, peb txhua xyoo muaj peev xwm ncav cuag li 2000, 000 daim. Dab tsi ntxiv, rail pads rau siab -peed rail yog peb cov khoom tshwj xeeb, nrog rau ob qho tib si elastic roj hmab daim hlau thiab qhov siab hloov cov ntaub qhwv.
Cov yam ntxwv ntawm Rubber Rail Pad los ntawm GNEE RAIL
- Shock absorption, aging kuj, puas ntsoog, stability, thermal stress resistance. Rubber rail pads yog ua los ntawm cov roj hmab ntuj, butadiene -styrene roj hmab, chloroprene roj hmab nplaum, HDPE thiab EVA. Cov roj hmab rail pads ua los ntawm GNEE RAIL muaj ntau yam nta xws li siab elasticity, tsis yog - deformation thiab tsis - tawg nyob rau hauv ib tug loj ntau yam ntawm kub.
- Lub neej ua haujlwm ntev, tsis tshua muaj txij nkawm thiab hloov cov nqi.
Peb tuaj yeem tsim ntau yam qauv ntawm cov roj hmab rail pads nrog cov ntaub ntawv sib txawv, cov roj hmab rail pads yog tsim rau cov ntoo railway sleepers, qhob railway sleepers thiab steel railway sleepers.
