Rail padsyog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau infrastructure uas ua lub luag haujlwm tseem ceeb hauv kev ua kom cov tsheb ciav hlau du thiab nyab xeeb. Cov ntaub qhwv no tau muab tso rau hauv nruab nrab ntawm cov ntsia hlau thiab lub rooj tsav tsheb, ua lub cushion kom nqus cov kev poob siab thiab kev vibration los ntawm cov tsheb ciav hlau hla.
Vim li cas kev siv Rail Pads tseem ceeb rau kev ua haujlwm kev tsheb ciav hlau?
Rail pads yog qhov tseem ceeb rau kev nyab xeeb kev tsheb ciav hlau vim tias lawv ua lub hauv ncoo tseem ceeb, nqus cov kev poob siab thiab kev co los ntawm cov tsheb ciav hlau, uas tiv thaiv kev puas tsuaj thiab hnav ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog, txo cov suab nrov, txhim kho kev ruaj ntseg los ntawm kev tiv thaiv kev tsis sib haum, thiab txuas ntxiv lub neej ntawm tag nrho cov qauv kev taug qab, ua kom ntseeg tau, du, thiab kev nyab xeeb kev ua haujlwm.
Lub luag haujlwm ntawm txoj kev tsheb ciav hlau yog dab tsi?
Feem ntau, lub luag haujlwm tseem ceeb ntawm cov roj hmab rail pads yog txo qhov siab - ceev kev co thiab cuam tshuam ntawm steel rails, tiv thaiv txoj kev tsheb ciav hlau txaj thiab cov pw tsaug zog, thiab ua hluav taws xob rwb thaiv tsev rau cov ntaub ntawv kaw lus. Thaum lub sij hawm daim ntawv thov, cov roj hmab rail pads feem ntau muaj nyob rau hauv cov huab cua. Yog li thiaj li ua kom lub neej ntev ntawm cov roj hmab rail pads, peb yuav tsum txhim kho cov kev laus tiv thaiv, txias -resistant, tshav kub tsis kam thiab rot tsis kam ntawm roj hmab rail pads.
Cov ntaub ntawv dab tsi yog siv los tsim elastic rail pads?
Elastic rail pads yog tsim los ntawm ntau yam polymers thiab roj hmab zoo li Ntuj Roj Hmab (NR), SBR, EPDM, thiab Polyurethane, feem ntau sib xyaw nrog cov khoom ntxiv xws li silica rau cov kav ntev, los yog cov yas zoo li HDPE thiab EVA, qee zaum ua ke nrog hlau rau siab -kev ua tau zoo, tag nrho cov xaiv rau lawv cov cushioning, rwb thaiv tsev, thiab loading tsis muaj zog{1}.

Dab tsi yog qhov hardness ntawm rail pad?
Rail ncoo hardness txawv ntawm cov khoom tab sis feem ntau teev nyob rau hauv Shore hardness (A scale) los yog txhav (KN), nrog rau cov txiaj ntsig zoo liNtug 90A (rau EVA) txog 98A, los yog nruj ntau yam ntawm90-130 KN, tsim los muab qhov tseem ceeb elasticity, dampen vibrations, thiab tiv thaiv cov neeg pw tsaug zog los ntawm kev cuam tshuam kev tsheb nqaj hlau, feem ntau siv cov roj hmab los yog cov yas sib xyaw.
- Roj Hmab Rail Pads: Feem ntau nyob ib ncig ntawm ntug dej hiav txwv 72-80 (Shore A nplai), lossis teev los ntawm kev nruj (xws li, 90-130 KN).
- EVA (Ethylene-Vinyl Acetate) Pads: tuaj yeem nyuaj, nrog cov kev xav tau zoo li Ntau dua lossis sib npaug rau 90A.
- HDPE (High-Density Polyethylene) Pads: Tej zaum yuav ncav cuag ntau dua lossis sib npaug rau 98A hardness.
Raws li cov kws tshaj lij roj hmab rail pad chaw tsim tshuaj pausGNEE RAILtuaj yeem tsim ntau yam qauv ntawm cov roj hmab rail pads thiab lwm yam rail fasteners. Yog tias koj xav tsim txoj kab tsheb ciav hlau, tsis txhob yig tiv tauj peb, peb tuaj yeem muab txhua hom roj hmab rail pads nrog cov ntaub ntawv sib txawv. Yog tias tsim nyog, peb tuaj yeem ua customized rubber rail pad ntau lawm.
