grooved rubber ncoo specifications
Rail ncoo, yog rail roj hmab phaj nruab nrab ntawm lub tsheb ciav hlau khi phaj thiab ko taw ntawm txoj kev tsheb ciav hlau, ua los ntawm elastic polyurethane, uas yog interposed ntawm steel rails thiab sleepers kom txo tau kev sib txhuam thiab kev cuam tshuam. Rail pads yog fastened nyob rau hauv ib tug fastening system los ntawm cov ntsia hlau spikes los yog rail bolts rau hauv lub sleeper ties.
Grooved roj hmab ncoospecifications sib txawv los ntawm daim ntawv thov (xws li, railway, workbench) tab sis feem ntau tsom rau cov khoom (Rubber, EVA, TPEE), hardness (Shore A los yog HRC), tensile lub zog, elongation, kev khiav hauj lwm kub ntau yam, thiab tshwj xeeb qhov ntev / tuab los xyuas kom meej kev co dampening thiab durability, feem ntau nrog ntxiv dag zog xws li nylon los yog hlau rau ntxiv rigidity.
Key parameters include Shore Hardness (90-95A for EVA, 50-70HRC for heavy duty), Elongation (>250%), Tensile Strength (nyob ib ncig ntawm 16 N / mm²), thiab kub kam rau ua (-40℃rau +70℃lossis siab dua).

- Kev txhawb zog: Nylon cords los yog nyias cov ntawv hlau rau kev txhim kho kev nruj, tshwj xeeb tshaj yog nyob rau hauv kev siv tsheb ciav hlau.
Lub cev muaj zog:
- Ntug Hardness: Ntau yam ntawm 90-95 Shore A (rau EVA) txog 50-70 HRC (rau cov roj hmab hnyav dua), cuam tshuam rau qhov tawv nqaij.
- Tensile zog: Yam tsawg kawg nkaus nyob ib ncig ntawm 16 N / mm² (los yog 16 MPa) rau EVA.
- Elongation ntawm Break: Typically >250% rau zoo elasticity.
- Compressive kev nyuaj siab: Max pom zoo nyob ib ncig ntawm 10 N / mm² rau qee cov ntaub ntawv.
Performance & Durability:
Ua haujlwm kub: Dav dav, piv txwv li, -25℃rau +75℃(EVA) lossis -40℃rau +230℃(hnyav roj hmab), nyob ntawm cov khoom siv.
Kev vibration Dampening: Tshwj xeeb nruj (elasticity) tsim los txo kev poob siab thiab suab nrov.
Kev tiv thaiv: Hluav taws xob tiv thaiv (rau rwb thaiv tsev), dej immersion kuj.
Dimensional & Tsim:
- Thickness: Nws txawv heev (piv txwv li, 6mm, 10mm rau rail pads).
- Grooves: Cov qauv thiab qhov tob tsim los rau kev tsheb ciav hlau / cov khoom sib cuag thiab cov dej ntws tawm.
- Cov qauv: Ua raws li UIC, AREMA, lossis cov qauv kev tsheb ciav hlau tshwj xeeb (piv txwv li, IRS-T-55).
GNEE RAILequips 130sets machine 'rail pad ntau lawm kab, rau kev ua, txhaj tshuaj, refining roj hmab, sulfuration, molding thiab soj ntsuam thiab lwm yam. Peb muaj peb tus kheej rail pad txhim kho engineers, tsim, tsim thiab tshuaj xyuas, peb txhua xyoo muaj peev xwm ncav cuag li 2000, 000 daim.
Piv nrog rau lwm yam railway roj hmab pads, peb cov khoom kev pab cuam lub neej muaj peev xwm mus txog 3 zaug ntev dua lawv. Cov kev ntsuam xyuas tau ua pov thawj tias qhov siab ntawm ntau tshaj 80 tons tuaj yeem ruaj khov yam tsis muaj deformation rau peb cov khoom. Siv high - thev naus laus zis ntau lawm, peb cov roj hmab railway pads xaiv cov roj hmab zoo li cov khoom siv raw, ua tib zoo tsim thiab ua nrog cov qauv kev tshawb fawb. Lawv tau ua tiav raws li kev tsheb ciav hlau ceev thiab cov kev cai ntawm kev tiv thaiv ib puag ncig, yog li lawv tuaj yeem siv los txhim kho lub tsheb thauj mus los.
