Nyob rau hauv pw tsaug zog padsmuab kev tiv thaiv kev vibration, khaws cov ballast hauv qab lem thiab txhim kho kev ruaj ntseg. Lawv tuaj yeem ntsia tau ob qho tib si hauv high - cov kab tsheb ciav hlau ceev thiab hauv cov kab uas muaj lub nra hnyav, nrog rau hauv cov kab ntsuas kab uas twb muaj lawm, thaum kho thiab rov kho dua.
Ua tsaug rau qhov kev ua kom zoo dua qub, GNEE hauv qab cov ntaub so ntswg pw tsaug zog ua ntej - haum rau cov neeg pw tsaug zog thaum lub sijhawm tsim khoom. Yog li ntawd, tsis tas yuav tsum ua haujlwm ntxiv ntawm qhov chaw teeb tsa. Kev teeb tsa tau nrawm, tsis cuam tshuam los ntawm huab cua thiab tuaj yeem ua tiav nrog kev cuam tshuam tsawg kawg nkaus.
Lub luag haujlwm ntawm hauv qab - khi (pw tsaug zog) ncoo yog dab tsi?
Hauv qab - khi (pw tsaug zog) pads yog cov khaubncaws sab nraud povtseg ntawm cov tsheb ciav hlau pw tsaug zog thiab ballast kom txo qis kev vibration, suab nrov, thiab ballast hnav, nce kev ruaj ntseg, tivthaiv lub neej, thiab caij kev nplij siab. Lawv ua tiav qhov no los ntawm kev ua kom thaj chaw sib txuas ntawm cov neeg pw tsaug zog thiab ballast, uas txo qis kev sib cuag, cov kev cuam tshuam hauv ncoo, thiab faib cov khoom thauj tau zoo dua, tshwj xeeb tshaj yog nyob rau hauv cov chaw xws li tunnels, txuas hniav, lossis siab - kab ceev.
Lub luag haujlwm tseem ceeb:
- Kev vibration & suab nrov Dampening: nqus kev poob siab thiab txo kev sib kis ntawm kev vibration thiab suab nrov, txhim kho cov neeg caij tsheb kev nplij siab thiab tiv thaiv ib puag ncig cov qauv.
- Kev Tiv Thaiv Ballast: Tiv thaiv kev tawg thiab kev sib haum xeeb los ntawm kev cuam tshuam ntawm cushioning, ncua sij hawm ntawm kev saib xyuas (tamping).
- Txhim kho Kev ruaj ntseg: Tsim kom muaj kev sib tw zoo dua qub, ua rau kev taug qab zoo dua geometry thiab kev ruaj ntseg tag nrho, tshwj xeeb tshaj yog qhov tob tob tob.
- Extended Component Life: Txo kev ntxhov siab thiab ua puas ntawm cov neeg pw tsaug zog, ntsia hlau, thiab fasteners, yog li ua kom lub neej ntev ntawm cov ntsiab lus.
- Txhim khu kev ua tau zoo: Pab tau siab -ceev, hnyav- tsheb thauj mus los, thiab hauv nroog tsheb ciav hlau los tswj kom muaj zog ntau zog thiab xav tau kev ntseeg siab.
Dab tsi yog cov ntaub ntawv siv los tsim Cov Khoom Siv Hauv Cov Pw Tsaug Zog?
Nyob rau hauv Sleeper Pads (USPs) feem ntau yog tsim los ntawm cov khoom siv ruaj khov, cov khoom siv elastomeric zoo li roj hmab (SBR, EPDM), polyurethane (PUR), thiab EVA (ethylene vinyl acetate), feem ntau sib txuas nrog cov resins lossis muaj cov fibers ntxiv rau lub zog ntxiv thiab kev co damping, nrog qee cov tuam txhab siv cov roj hmab rov ua dua} ntawm qhov kawg ntawm {{0}.
Cov ntaub ntawv tseem ceeb & hom:
- Cov Khoom Roj Hmab: Cov roj hmab ntuj, Styrene-Butadiene Rubber (SBR), thiab Ethylene Propylene Diene Monomer (EPDM) yog ib qho zoo rau lawv cov kev sib cais zoo heev thiab ua haujlwm ntev.

- Resin-Cov Roj Hmab Cov Roj Hmab: Siab- cov roj hmab zoo (zoo li cov log tsheb rov qab) tau khi ua ke nrog cov resins los tsim cov ntaub ntom ntom, muaj zog.
- Cov Khoom Siv Muaj Zog: Qee cov ntaub qhwv cov ntaub qhwv cov ntaub ntawv fiber ntau (xws li iav lossis hluavtaws fibers) hauv cov txheej elastomer kom muaj zog ntxiv thiab kev ua haujlwm zoo.
Raws li ib tug kws rail fastener chaw tsim tshuaj paus,GNEE RAIL cib qho tsim ntau hom roj hmab rail pads nrog cov ntaub ntawv sib txawv, xws li cov 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.
