Yuav ua li cas los txhim kho qhov kev tiv thaiv -deformation peev xwm ntawm Rail Pads?
Txhawm rau txhim kho lub peev xwm tiv thaiv - deformation ntawmrail pads, koj tuaj yeem txhim kho lawv cov khoom muaj pes tsawg leeg los ntawm cov tswv yim xws li kev hloov kho silica fillers lossis siv cov khoom sib xyaw xws li cork- roj hmab. Lwm cov tswv yim suav nrog kev siv cov ntaub ntawv zoo tshaj plaws xws li hlau cushions lossis polyurethane, txhim kho cov txheej txheem vulcanization kom nce tus ntoo khaub lig- txuas, thiab xyuas kom meej cov khoom zoo yog khaws cia thoob plaws qhov kub thiab txias.
Cov khoom siv thiab kev sib xyaw ua kom zoo dua
- Txhim kho nrog hloov kho silica:Muab cov silica hloov kho rau hauv cov roj hmab ncoo, uas ua rau cov tshuaj lom neeg ntau dua -txuas thiab tawv, ua rau qis deformation.
- Siv cov khoom sib xyaw:Cork- cov khoom siv roj hmab tuaj yeem muab qhov sib npaug zoo ntawm elasticity thiab nruj. Qhov no tuaj yeem ua rau muaj kev ua haujlwm ruaj khov dua nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, vim tias lub cork muab qhov muaj zog thiab damping.
- Ua haujlwm siab - ua tau zoo polymers:Tshawb nrhiav cov ntaub ntawv zoo li polyurethane, uas tuaj yeem ua rau muaj qhov deformation loj yam tsis muaj deformation mus tas li, ua rau nws muaj zog sib tw rau kev txhim kho kev ua haujlwm.
- Xav txog cov cushions hlau:Hloov cov tsoos polymer pads nrog hlau cushions, raws li lawv tau thov los ua lwm txoj hauv kev uas ua tau zoo dua cov polymers ntawm kev laus degradation.
Environmental thiab kev ua haujlwm xav tau
- Qhov chaw nyob qhov kub thiab txias:Siv cov khoom siv nrog kev ua haujlwm zoo ib yam thoob plaws qhov kub thiab txias, xws li cork- cov khoom siv roj hmab, los tiv thaiv kev muag muag ntau dhau ntawm qhov kub thiab txias ntawm qhov kub tsawg.
- Ua raws li kev saib xyuas thiab tshuaj xyuas kom raug:Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua, ua ke nrog kev taug qab thiab cov qauv kev nyab xeeb, tuaj yeem pab txo qis kev pheej hmoo cuam tshuam nrog deformation.
- Control khiav tej yam kev mob:Thaum tshav kub kub heev, kev siv cov kev txwv ceev rau cov tsheb ciav hlau tuaj yeem txo cov rog ntawm txoj kev khiav thiab pab tiv thaiv buckling.
Rail pads rau Normal Railways
Rail pads yog elastic polyurethane mats uas yog interposed ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum los ntawm hnav thiab cuam tshuam.
Qhov pib tawv ntawm lub tsheb ciav hlau yog tsim los kom tsis txhob siab kom lawv cov txheeb ze deformation nyob rau hauv lub caij nplooj ntoos hlav clip ntiv taw loads yog heev loj. Nyob rau hauv txoj kev no, nws tuaj yeem lav qhov kev tsheb ciav hlau pad tuav hauv kev sib raug zoo nrog cov tsheb ciav hlau txawm tias muaj kev txav ntsug ntawm qhov kawg. Tsis tas li ntawd, vim li cas vim li cas cov tsheb ciav hlau ua los ntawm cov roj hmab los yog cov yas yog ua rau cov kev poob siab ntawm kev vibration ntawm lub tsheb ciav hlau hla.
