Yuav Ua Li Cas Rail Pads Pab Txhawb Nqa Txoj Kev Taug Kev Ntev?
Rail padsyog elastic polyurethane lev uas yog interposed ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
Hauv kev saib xyuas kev tsheb ciav hlau, ballast pulverization thiab sleeper cracking yog ob yam tseem ceeb uas ua rau luv luv taug qab txoj sia. Lub tsheb ciav hlau pad, nyob hauv qab ntawm txoj kev tsheb ciav hlau, ua haujlwm ua thawj lub cev thaiv kev tiv thaiv cov txheej txheem tsis ua haujlwm. Los ntawm kev siv nws cov viscoelastic damping zog, nws hla txoj kev sib kis ntawm siab - zaus vibrations. Txawm li cas los xij, qhov ua tau zoo ntawm qhov kev tiv thaiv no tsuas yog nyob ntawm cov txheej txheem tsim khoom thiab cov khoom siv ntev ntawm lub ncoo nws tus kheej.
Ua ntej, lub neej ntev ntawm lub txaj ballast yog ncaj qha proportional rau qhov poob siab -absorbing peev xwm ntawm lub ncoo.Yog tias qhov cuam tshuam lub zog tsim los ntawm kev hla kev tsheb ciav hlau tsis zoo absorbed los ntawm rail roj hmab ncoo, nws kis ncaj qha mus rau lub ballast, ua rau pob zeb abrasion thiab pulverization, uas ua rau taug qab kev sib haum xeeb.
NtawmGNEE RAIL, peb R & D tsom rau kev txhim kho hysteresis poob yam ntxwv ntawm roj hmab molecules. Los ntawm kev tswj hwm vulcanization, peb cov pawm hloov ib feem tseem ceeb ntawm cov tshuab hluav taws xob rau hauv tshav kub thaum muaj kev cuam tshuam. Laboratory cov ntaub ntawv los ntawm peb cov kev ntsuam xyuas zoo li qub thiab dynamic rigidity qhia tau hais tias peb optimized formulations ho ncua ballast compaction, yog li txo qhov zaus ntawm yuav tsum tamping tu.

Qhov thib ob, kev tiv thaiv cov neeg pw tsaug zog los ntawm kev puas tsuaj yog qhov tseem ceeb rau kev ua kom lub neej ntev.Micro-kev txav ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog ua zoo li cov ntawv xuab zeb, hnav hauv qhov chaw pw hauv lub sijhawm.
Lub tsheb ciav hlau elastic ncoo ua los ntawm GNEE RAIL siv siab - hnav- tiv taus HDPE lossis EVA cov ntaub ntawv sib xyaw. Ua ke nrog siab -precision txhaj tshuaj molding, peb xyuas kom meej meej textures thiab qhov ntev. Qhov kev nruj nruj no txwv txoj kev tsheb ciav hlau micro- kev txav chaw, tshem tawm qhov tshwm sim ntawm "sleeper attrition."

Thaum kawg, kev ruaj ntseg ntawm lub fastening system nyob ntawm qhov elastic tuav ntawm lub ncoo.Yog hais tias ib lub ncoo undergoes yas deformation (them mus tas li), lub clamping quab yuam ntawm lub fastener ploj mus, ua rau clip loosening los yog puas.
GNEE RAILtswj xyuas qhov kev qaug zog ntawm kev ntsuas txog li 3 lab lub voj voog thauj khoom; tsuas yog batch nrog residual deformation tus nqi qis dua qhov txwv tau tso tawm. Qhov kev ntsuam xyuas huab cua no ua kom muaj kev ruaj ntseg kom ntseeg tau tias txoj kev tsheb ciav hlau tuav nws cov qauv tsim nyob rau hauv nws lub neej ntev kev pab cuam, tsis tu ncua muab ruaj khov preload rau lub fastening system thiab lav lub sij hawm ntev - lub sij hawm ua hauj lwm ncaj ncees ntawm txoj kab.
GNEE RAILMuaj ntau hom kev tsheb ciav hlau fasteners kom tau raws li cov neeg siv khoom xav tau, xws li Elastic Rail Clip thiab Clamp, Rail Screw Spike, Yas Dowel, High Tensile Track Bolt nrog txiv ntseej, Rail Base (Tie) Phaj, Rail Fish Plate, Railway Shoulder (Ntxig), Ntses Bolt, Railroad Rubber thiab EVA Pad, thiab lwm yam.
