railway pads yog dab tsi?

 

Covrail ncoo, tseem hu ua cov phaj hauv qab, yog ib qho elastic polyurethane ncoo sib sau ua ke ntawm cov ntsia hlau thiab pw tsaug zog los tiv thaiv sab saum toj ntawm tus neeg pw tsaug zog los ntawm kev hnav thiab cuam tshuam. Thawj qhov nruj ntawm lub tsheb ciav hlau tsis yog siab heev uas qhov deformation ntawm cov ntsia hlau nyob rau hauv lub load ntawm lub caij nplooj ntoos hlav yog loj heev. Cov txheej txheem no ua kom lub tsheb ciav hlau txav ze li sai tau kom paub txog kev sib raug zoo nrog txoj kev khiav.

 

 

Raws li cov chaw tsim khoom ntawm kev tsheb ciav hlau, GNEE RAIL muaj peev xwm tsim cov tsheb ciav hlau ntawm ntau lub tsheb ciav hlau, xws li UIC54, UIC60, BS80lbs, BS100lbs thiab lwm yam. Tsis tas li ntawd, peb tuaj yeem muab kev cai- ua cov ntaub qhwv raws li cov duab kos lossis cov qauv.

 

Dab tsi yog rail pads ua los ntawm?

 

Rail ncoo, los yog hu ua rail elastic pad, hais txog ib lub ncoo ua los ntawm roj hmab los yog yas, uas yog ntsia nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb hauv qab - txoj kev tsheb ciav hlau. Lub luag haujlwm tseem ceeb ntawm kev tsheb ciav hlau elastic ncoo yog kom tsis txhob muaj qhov siab - nrawm nrawm thiab kev vibration tsim thaum lub tsheb hla txoj kev tsheb ciav hlau, tiv thaiv txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog, thiab hluav taws xob rwb thaiv tsev cov teeb liab kev tsheb ciav hlau.

 

Lub ntiaj teb tam sim no - siv dav siv cov ntaub ntawv elastic rail ncoo suav nrog:

 

• Cov khoom siv roj hmab: Cov roj hmab ntuj, Styrene-butadiene roj hmab (SBR), Neoprene, Nitrile roj hmab, EPDM roj hmab (Ethylene Propylene Diene Monomer Rubber)

 

• Cov khoom siv yas (HDPE, EVA, Nylon PA 6)

 

• TPV{0}} Thermoplastic Elastomer Dynamic Vulcanizate

 

• Micro-foamed cov ntaub ntawv (Micro-foamed TPE, TPU, TPV)

 

• Micro-ua npuas ncauj thermoplastic elastomer

 

• Lwm cov ntaub ntawv sib xyaw

Tom qab kev sib piv, nws tsis yooj yim rau kev nrhiav, uas muaj qhov nyuaj heev hauv kev tau txais cov khoom tsis muaj thiab cov khoom siv uas muaj feem xyuam rau ntau yam kev mob. Yog li yuav tsum tau xaiv cov khoom tsim nyog rau kev tsheb ciav hlau pad xav txog ob qho tib si cov nqi thiab kev ua tau zoo ntawm cov tuam txhab tsheb ciav hlau hauv zos.
