Yam khoom siv rail pad twg yog qhov zoo tshaj?
Ib qho ntawm cov lus nug nquag tshaj plaws hauv railway engineering procurement yog: Qhov twgrail ncoocov ntaub ntawv zoo tshaj plaws? Cov lus teb ncaj ncees yog tias tsis muaj "ib qho- loj- haum-tag nrho" kev daws teeb meem. Kev ua tau zoo ntawm Rail Pad nyob ntawm qhov chaw ua haujlwm, qag loads, thiab kev vibration damping yuav tsum. Xaiv cov khoom tsim nyog yog qhov tseem ceeb rau kev ua kom lub neej zoo ntawm tus nqi khiav.
1. HDPE (High-Density Polyethylene): Lub Hnyav Haul Champion
Rau hnyav- cov kab thauj khoom thauj lossis kev lag luam uas yuav tsum tau muaj kev nruj nruj, HDPE Pad feem ntau yog qhov kev xaiv. Hom Railroad Pad no yog nruj thiab ruaj khov. Nws tiv taus deformation nyob rau hauv loj heev ntsug loads, tiv thaiv rail tilting. Thaum nws muaj qhov elasticity tsawg dua li cov roj hmab, nws hnav tsis kam thiab tus nqi -kev ua tau zoo ua rau nws zoo tagnrho rau qis - nrawm, siab - daim ntawv thov load.

| Technical Parameter | Chav tsev | Kev Xav Tau | Tus nqi |
| Qhov ntom | g/cm3 | 0.95-0.98 | 0.95 |
| Tensile zog | Mpa | Ntau dua lossis sib npaug li 19 | 19 |
| Elongation | % | >80 | 150 |
| Melting Point | degree | 170-190 | 190 |
| Rwb thaiv tsev Resistance | Ω | Loj dua los yog sib npaug rau 1 × 1010 | 3.5 ×1010 |
| Hardness | A | Ntau dua lossis sib npaug li 98 | 98(A) |
2. Roj Hmab (Natural / Synthetic): Qhov tseem ceeb rau kev kub ceev & kev thauj mus los
Thaum cov neeg caij tsheb kev nplij siab thiab kev vibration attenuation yog qhov tseem ceeb, xws li hauv High -Speed Rail lossis Metro systems, Rail Rubber Pad yog qhov kev xaiv zoo tshaj. Cov Rail Elastic Pads yog tsim los ntawm siab -cov khoom siv roj hmab zoo los yog cov khoom siv hluavtaws los muab kev ua haujlwm zoo. Lawv nqus dynamic shocks, tiv thaiv pob zeb pw tsaug zog los ntawm tawg. Ib yam li ntawd, advanced Under Sleeper Pads feem ntau siv cov ntaub ntawv no los ua kom lub suab nrov ntxiv thiab kev co.

| Technical Parameter | Chav tsev | Tus nqi |
| Kev nruj | KN | 90-130 |
| Hardness Ntug A | degree | 72-80 degree |
| Electronic Resistance | Ω | Ntau dua lossis sib npaug rau 106 |
| Tensile zog ua ntej kev laus | Mpa | Ntau dua lossis sib npaug li 12.5 |
| Elongation ua ntej kev laus | % | Ntau dua lossis sib npaug li 250 |
3. EVA (Ethylene Vinyl Acetate): Tus Neeg Ua Haujlwm Sib Nqus
EVA muaj qhov nruab nrab hauv nruab nrab ntawm qhov rigidity ntawm cov yas thiab qhov yooj ntawm cov roj hmab. Ib qho EVA Railway Pad muab qhov nruab nrab damping thiab ua haujlwm zoo, ua rau nws yog qhov kev xaiv nrov rau kev sib xyaw ua ke - cov kab tsheb thauj mus los uas ob qho tib si thauj khoom thiab cov neeg caij tsheb ciav hlau khiav lag luam.

| Technical Parameter | Chav tsev | Kev Xav Tau | Tus nqi |
| Qhov ntom | g/cm3 | 0.95-0.98 | 0.95 |
| Tensile zog | Mpa | Ntau dua lossis sib npaug li 15 | 16 |
| Elongation | % | >500 | 550 |
| Melting Point | degree | 170-190 | 170 |
| Rwb thaiv tsev Resistance | Ω | Loj dua los yog sib npaug rau 1 × 1010 | 5.0 ×1010 |
| Hardness | A | Ntau dua lossis sib npaug li 90 | 92(A) |
