Dab tsi yog railway phaj?
Railway puag phaj pads(lossis baseplate pads) yog qhov tseem ceeb elastic, tsis yog{0}} cov khoom siv hlau (rubber, polyurethane, lossis EVA) muab tso rau nruab nrab ntawm lub rooj tsav tsheb (los yog steel baseplate) thiab cov pob zeb pw tsaug zog / slab. Lawv ua haujlwm los ua kom tsis muaj kev vibration, muab hluav taws xob rwb thaiv tsev, txo cov suab nrov ntawm cov qauv, thiab sib npaug faib cov tsheb ciav hlau thauj khoom, yog li txuas ntxiv kev ua neej nyob.

Kev siv piv txwv & ua haujlwm
- Vibration Mitigation:Nruab nyob rau hauv rail baseplates los nqus poob siab los ntawm siab -ceev los yog hnyav- tsheb ciav hlau, txo suab nrov.
- Slab Track Systems:Muab tso rau ntawm lub phaj phaj thiab cov pob zeb ua vaj tse los muab qhov tsim nyog elasticity thiab txo cov txheej txheem qaug zog.
- Rail Seat Protection:Tiv thaiv kev puas tsuaj rau pob zeb pw tsaug zog tshwm sim los ntawm kev puas tsuaj los ntawm steel baseplate.
- Rail Maintenance:Siv los txo cov tsheb ciav hlau deflection thiab du lub caij zoo thaum caij tsheb ciav hlau hla.
- Rwb thaiv tsev:Muab hluav taws xob cais rau cov teeb liab.
Cov txiaj ntsig tseem ceeb ntawm Rail Pads yog dab tsi?
Rail pads, muab tso rau hauv nruab nrab ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog, feem ntau txhim kho txoj kev tsheb ciav hlau ntev thiab kev nyab xeeb los ntawm kev ua ib qho tseem ceeb, elastic, thiab damping tivthaiv. Lawv cov txiaj ntsig tseem ceeb suav nrog kev txo qis kev poob siab, cuam tshuam, thiab kev vibrations resonant (tshwj xeeb tshaj yog rau cov neeg pw tsaug zog), uas txo qis suab nrov, tiv thaiv kev sib tsoo thiab kev sib tsoo, txhim kho qhov kev ntsuas, thiab txhim kho kev caij tsheb zoo.
Cov txiaj ntsig tseem ceeb ntawm rail pads:
- Kev vibration thiab suab nrov txo:Lawv tau txais txiaj ntsig zoo, siab - kev vibrations ceev, txo cov suab nrov rau thaj chaw ib puag ncig thiab txhim kho cov neeg caij tsheb.
- Load Distribution thiab Shock Absorption:Pads faib qhov hnyav ntsug ntawm cov tsheb ciav hlau hla thaj chaw loj dua ntawm cov neeg pw tsaug zog, tiv thaiv kev ntxhov siab hauv zos, qaug zog tawg hauv pob zeb, thiab txo qis hnav.
- Kev tiv thaiv ntawm Track Components:Los ntawm kev muab cov txheej txheem cushioning, lawv tiv thaiv kev puas tsuaj thiab tawg, tiv thaiv ob qho tib si pob zeb thiab ntoo pw ntawm hnav.
- Txhim kho Track Stability:Lawv tuav txoj kab ntsuas ntsuas thiab txhim kho kev ruaj ntseg, tiv thaiv kev xoob ntawm cov tsheb ciav hlau fasteners.
- Hluav taws xob rwb thaiv tsev:Lawv muab cov rwb thaiv tsev tseem ceeb ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog, qhov tseem ceeb rau cov teeb liab niaj hnub.
- Cov Khoom Siv Ntev Ntev Ntev thiab Txo Kev Kho Mob:Los ntawm kev txo qhov kev puas tsuaj thiab qaug zog, lawv txuas ntxiv lub neej ntawm cov ntsia hlau, fasteners, thiab sleepers, txo cov nqi txij nkawm ntev -.
Yuav ua li cas rail elastic pads tsim?
Rail elastic pads yog tsim los ntawm molding ntawm cov roj hmab tebchaw (natural, SBR, EPDM) los yog thermoplastics (EVA, HDPE) siv txhaj tshuaj los yog compression molding, ua raws li vulcanization los txhim kho elasticity thiab durability. Cov txheej txheem suav nrog kev npaj cov khoom siv, ua kom nws nyob rau hauv qhov kub thiab txias, kev txiav, thiab kev tswj xyuas nruj kom ua tau raws li qhov xav tau ntawm kev thauj khoom- deflection.
Cov kauj ruam tseem ceeb ntawm kev tsim khoom:
- Kev Npaj & Compounding:Cov ntaub ntawv nyoos yog sib xyaw nrog cov tshuaj ntxiv dag zog, cov khoom ntim, thiab cov tshuaj tua kab mob hauv cov khoom siv sab hauv lossis ntawm ob- yob zeb kom ua tiav qhov tsim nyog elasticity thiab lub zog.
- Moulding:Lub compound yog zoo li tus mus rau hauv tej qhov ntev siv compression los yog txhaj molding cov tswv yim.
- Vulcanization (Curing):Cov ntaub qhwv molded tau txais kev kub siab - kub thiab siab - siab kho kom hla- txuas polymers, ua kom muaj zog, hnav tsis kam, thiab tsim nyog, zoo ib yam elasticity.
- Tiav & Kev Tshuaj Xyuas:Cov ntaub qhwv tiav raug txiav kom tshem tawm cov khoom siv ntau dhau thiab ua tib zoo kuaj kom zoo thiab ua haujlwm zoo.
