A rail ncoo, tseem hu ua rail roj hmab phaj, feem ntau yog siv ntawm khi daim hlau thiab cov neeg pw tsaug zog lossis nruab nrab ntawm cov ntsia hlau thiab khi phaj. Lub rail ncoo yog ua los ntawm elastic polyurethane lev thiab feem ntau yog siv rau cov pob zeb pw tsaug zog. Lub rail ncoo tuaj yeem tiv thaiv lub pob zeb pw tsaug zog los ntawm kev puas tsuaj thiab kev cuam tshuam, thiab nws tuaj yeem txo qhov kev vibration ntawm lub tsheb ciav hlau hla. Nws ntseeg tau tias txoj kev tsheb ciav hlau ua haujlwm hauv ob txoj hauv kev: txo qis kev poob siab thiab faib cov khoom thauj. Lub thickness ntawm peb rail pads yog li ntawm 5mm mus rau 25mm, tab sis feem ntau qhov siab yuav tsum tsis txhob yuav siab heev nyob rau hauv cov ntaub ntawv ntawm kev txav mus los ntawm cov ntsia hlau.
Vim li cas HDPE siv los tsim cov tsheb ciav hlau?
HDPE (High-Density Polyethylene) yog siv rau kev tsheb ciav hlau pads, tshwj xeeb tshaj yog nyob rau hauv hnyav- cov kab, vim hais tias nws muab siab nruj los tiv thaiv rail rollover, resists puas ntawm steel rails thiab qhob ties, muaj zoo heev durability, tshuaj lom neeg / dej tsis kam, thiab nqi{2}} ua hauj lwm hnyav, thaum tswj kev ua haujlwm zoo rigid shield dua ib tug shock absorber piv rau roj hmab.

Lub hardness ntawm HDPE rail ncoo yog dab tsi?
HDPE rail pads feem ntau muaj qhov nyuaj siab, feem ntau teev nyob ib ncig ntawm Ntau dua lossis sib npaug ntawm 98A (Shore A), muab qhov tsim nyog nruj thaum tseem muaj zog los tiv thaiv cov neeg pw tsaug zog los ntawm kev sib tsoo thiab kev cuam tshuam, txawm tias qee qhov kev hloov pauv muaj nyob ntawm kev tsim. Qhov hardness no ua kom cov khoom xa tawm zoo, tiv thaiv kev puas tsuaj rau cov neeg pw tsaug zog thiab txo qis kev co, ntsuas lub zog nrog kev xav tau elasticity rau kev siv tsheb ciav hlau.
Sib piv nrog lwm cov ntaub ntawv:
- Rubber Rail Pads: Feem ntau softer, nrog hardness qhov tseem ceeb ntawm 72-80 degrees (Shore A) thiab qis zog (90-130 KN).

Dab tsi yog txoj haujlwm ntawm lub tsheb ciav hlau?
Lub tsheb ciav hlau txoj haujlwm tseem ceeb yog ua lub ncoo ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog (kuav), tiv thaiv cov qauv kev sib tw los ntawm kev txo qis kev vibration, dampening cuam tshuam, kis tau cov khoom hnyav los ntawm cov tsheb ciav hlau, thiab tiv thaiv kev hnav, uas ua rau cov khoom muaj sia nyob, txhim kho cov neeg caij tsheb, thiab txo cov kev xav tau ntawm kev tu.
Peb cov EVA / HDPE / roj hmab rail pads yog nrog siab elasticity, thov rau hom kev tsheb ciav hlau xws li tsheb ciav hlau UIC54, UIC60, BS80lbs, BS100lbs, thiab ntau thiab tsawg raws li tau txiav txim. Cov ntaub qhwv tuaj yeem kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
