Qhov sib txawv ntawm EVA rail pads thiab HDPE rail pads
Nyob rau hauv cov kev qhia tshwj xeeb ntawm kev tsheb ciav hlau fastening systems, sib nrug los ntawm cov qauv roj hmab, cov ntaub ntawv thermoplastic zoo li HDPE (High-Density Polyethylene) thiab EVA (Ethylene Vinyl Acetate) ua lag luam. Rau cov thawj tswj kev yuav khoom, ob hom noRail PadsTej zaum yuav zoo li zoo sib xws ntawm kev kos duab, tab sis lawv muaj cov khoom sib txawv ntawm lub cev thiab cov qauv nqi. Nkag siab txog cov nuances ntawm lawv yog qhov tseem ceeb rau kev ua kom zoo ntawm ob qho tib si kev ua tau zoo thiab qhov project pob nyiaj siv.
Rail pad muaj nuj nqi
Rail roj hmab ncoo yog qhov tseem ceeb hauv kev txo qis kev poob siab thiab kev co hauv lub tsheb ciav hlau. Lub ncoo nteg nyob rau hauv lub tsheb ciav hlau los xyuas kom meej:
Load faib tshaj qhov loj dua
Tshem tawm ntawm load concentration thiab ua rau qaug zog stresses
Centering ntawm loads ntawm cov khoom txhawb nqa
Kev nqus ntawm qhov tsis sib xws ntawm qhov chaw sib txuas ntawm kev tsheb nqaj hlau thiab kev txhawb nqa
Txo cov suab nrov thiab kev co
Kev sib khi ntawm lub hauv qab ntawm txoj kev tsheb ciav hlau thiab sab saum toj ntawm kev txhawb nqa
Kev txo qis ntawm kev hnav ntawm txoj kev tsheb ciav hlau thiab nws txoj kev txhawb nqa
HDPE Railway Pads
HDPE Pad muaj npe nrov rau nws qhov siab nruj thiab kev ua haujlwm ruaj khov. Characterized by a dense molecular structure, it acts less like a cushion and more like a durable shield. Nws lub luag haujlwm tseem ceeb yog muab cov txheej txheem sib cais nruj uas tiv thaiv cov hlau rail los ntawm abrading lub pob zeb pw tsaug zog, tsis yog absorbing kev co. Qhov no ua rau Railroad Pad ua los ntawm HDPE qhov kev xaiv zoo tshaj plaws rau hnyav - cov kab tsheb thauj khoom uas tswj xyuas qhov ntsuas qhov tseeb yog qhov tseem ceeb. Nyob rau hauv qhov loj qag loads, ib tug softer ncoo yuav compress ntau dhau, pheej hmoo rail rollover, whereas HDPE tseem ruaj khov. Kev lag luam, nws feem ntau yog tus nqi ntau tshaj - kev xaiv zoo ntawm ntau yam Track Pad.

EVA Railroad Pads
Ntawm qhov tod tes, EVA Railway Pad ua haujlwm zoo li nruab nrab hauv nruab nrab ntawm cov yas thiab cov roj hmab elastic. Raws li ib tug copolymer, EVA integrates lub toughness ntawm polyethylene nrog rau qhov yooj ntawm vinyl acetate. Lub ntsiab lus txawv nyob rau hauv nws elasticity; EVA yog softer dua HDPE, cia nws ua haujlwm zoo li Rail Elastic Pad. Nws muaj cov khoom ua kom muaj kev vibration damping, ua rau nws haum rau kev sib xyaw ua ke - cov kab tsheb thauj mus los lossis hauv nroog tsheb thauj mus los uas txo cov suab nrov yog qhov tseem ceeb. Thaum me ntsis kim dua HDPE, EVA ua tau zoo hauv kev qaug zog thiab ua tau zoo tshwj xeeb hauv cov huab cua txias yam tsis muaj nkig.
