Yuav ua li cas los txhim kho lub deformation tsis kam ntawm railway pads?

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.

 

 

Yuav ua li cas los txhim kho lub deformation tsis kam ntawm railway pads?

 

Txhawm rau txhim kho railway ncoo deformation kuj, sivHloov kho cov khoom siv xws li tshuaj lom neeg silica (m-silica), optimize padthickness thiab ceev, xyuas kom raugxaiv cov khoom siv(piv txwv li, recycled log tsheb, TPE, EVA), thiab tsom rauchemical bondingnyob rau hauv cov roj hmab matrix rau muaj zog polymer chains, nrog rauyog installationnrog cov txheej txheem fastening tsim nyog thiab tsim nyog lub hauv paus / tsim nruj.

 

 

• Kev Txhim Kho Kom Zoo: Xyuas kom cov txheej txheem ua kom huv si thiab qhuav, thiab cov fasteners raug torqued kom raug los tiv thaiv kev sib raug zoo thiab kev ntxhov siab thaum pib.

 

• Kev tshuaj xyuas tsis tu ncua: Ua kom pom kev pom thiab siv tshuab kuaj xyuas kom pom kev tawg, tawg, thiab degradation ntawm cov khoom kom ntes cov cim ntxov ntawm kev ua tsis tiav.

 

• Kev xaiv cov khoom siv rau ib puag ncig: Xaiv cov ntaub qhwv nrog zoo tiv thaiv- kev laus thiab siab / qis- qhov kub thiab txias, tshwj xeeb tshaj yog nyob rau hauv cov ntug hiav txwv hnyav lossis cov mining.

 

Yam khoom siv railway pad twg muaj qhov muaj zog tiv thaiv deformation?

 

Rau qhov muaj zog deformation kuj nyob rau hauv txoj kev tsheb ciav hlau pads, polyurethane (PU) feem ntau outperforms txheem roj hmab vim nws superior hnav tsis kam (3-}5x roj hmab), siab mechanical zog, thiab tsis tshua muaj cua sov buildup nyob rau hauv rov qab loads, tuav elasticity ntev dua rau siab - ceev rail; though high-density rubber (Natural/SBR) also offers great elasticity, shock absorption, and durability, often with embedded steel for extra stiffness in studded designs.

 

Cov ntaub ntawv tseem ceeb & Lub zog:

 

 

• Polyurethane (PU): Qhov zoo tshaj plaws rau siab zog thiab hnav; zoo heev tiv thaiv siab - zaus cuam tshuam, ncua lub neej ntawm lub ncoo.

• EVA (Ethylene Vinyl Acetate): Muab qhov sib npaug zoo ntawm kev nruj thiab kev yooj yim, haum rau kev sib xyaw ua ke, muab kev ua kom tsis zoo.

 

• Studded / Grooved Rubber Pads: Roj Hmab nrog embedded steel ntawv muab siab resilience thiab nruj, yoog mus rau hnyav loads thiab txhim kho stability.

 

Peb EVA / HDPE / roj hmab rail pads yog nrog siab elasticity, siv rau cov hom kev tsheb ciav hlau xws li rail UIC54, UIC60, BS80lbs, BS100lbs, thiab ntau thiab tsawg raws li tau txiav txim. Cov ntaub qhwv tuaj yeem raug kho nrog lossis tsis muaj grooves, hauv ntau qhov tsim tau, nyob ntawm cov neeg siv khoom xav tau.
