Cov ntaub ntawv faib tawm thiab kev ua haujlwm Flapation yuav tsum muaj kev sib tw
Dab tsi yog cov khoom tseem ceeb hom ntawm nyob rau hauv - rail pads? Cov yam ntxwv ntawm txhua qhov yog dab tsi?
Nyob rau hauv {-} rail cov ntaub qhwv yog feem ntau muab faib ua ob pawg: roj hmab roj hmab thiab cov roj hmab hluavtaws. Cov Roj Hmab Roj Teeb muaj elasticity zoo heev thiab hnav tsis kam, thiab yog siv dav hauv cov kev tsheb ciav hlau cov tsheb ciav hlau. Cov roj hmab hluavtaws, sawv cev los ntawm styrene- butadiene roj hmab, haum rau cov kev tsis tshua muaj nqi, haum rau cov xwm txheej xws li Urban Rail Transit. Qee qhov xwm txheej tshwj xeeb siv EPDM roj hmab pads, uas muaj zog tiv taus rau cov siab thiab qis. Cov Roj Hmab Roj Teeb muaj cov kev ua tau zoo dua li cov roj hmab hluavtaws, tab sis me ntsis tsis muaj zog nyob hauv ib puag ncig. Kev xaiv cov khoom lag luam xav tau kev sib npaug kev ua tau zoo thiab cov nyiaj siv.
Cov qauv txheej txheem ntawm -} rail ntaub qhwv cuam tshuam rau kev siv cov nyhuv?
Nyob rau hauv -} Rail cov ntaub ntawv muaj cov qauv qauv xws li hom tiaj thiab grooved. Ca hom pads muaj cov qauv yooj yim thiab yooj yim installation, haum rau cov kab kev tsheb ciav hlau. Grooved yam cov ntaub qhwv tau zoo dua tso kua rau qhov kev ua tau zoo, uas tuaj yeem nrawm nrawm taug txoj kev taug kev ntawm cov dej noo thiab kom txo cov dej noo ntawm cov ntaub qhwv. Qhov zawj txheej txheem tseem tuaj yeem txhim kho cov nyhuv kom txo qis thiab txo cov co tes kis tau tsim los ntawm kev ua haujlwm tsheb ciav hlau. Kev siv tsheb nqaj hlau tsim hauv cov chaw los nag thiab cov ntaub qhwv cov ntaub qhwv kom txuas txoj kev pabcuam txuas ntxiv. Cov qauv qauv yuav tsum hloov mus rau cov yam ntxwv ib puag ncig thiab kev txo cov kev txo ntawm cov kab.
Dab tsi yog qhov yuav tsum tau ua rau lub hardness index ntawm - rail pads? Vim li cas nws tseem ceeb?
Lub hardness ntawm nyob rau hauv - rail pads yog tswj tau ntawm ntug dej ib qho kev nyuaj tsawg dua lossis sib npaug ntawm 5 kom paub tseeb tias elasticity. Tsis txaus siab yuav ua rau muaj kev cuam tshuam ntau dhau ntawm cov ntaub qhwv ntsej muag, cuam tshuam cov kev khiav geometric ruaj khov; Kev nyuaj ntau dhau yuav txo cov nyhuv kom txo qis thiab nce kev txhawb nqa haujlwm kev co. Sib txawv txoj kab muaj cov kev xav tau sib txawv; high - Kev tswj hwm tsheb ciav hlau siab xav tau kom muaj kev sib luag ruaj khov thiab kev co kom nruj, nrog stricter hardness tswj. Nroog Rail Transit muaj cov siab yuav tsum tau txo qis vim yog cov tsev ib puag ncig, thiab lub tshuab ua kom nruj yuav tsum sib phim. Lub zog kom tsim nyog yog lub hauv paus rau lub ncoo kom ua si lub luag haujlwm tsis zoo thiab kev co.
Qhov kev cuam tshuam rau ib qho chaw khaws cia muaj nyob rau hauv kev ua haujlwm ntawm - rail pads?
Ntev -}}} - rail pads rau qhov qis elasticity, tawv tawv thiab brittleness. Huab ib puag ncig yuav cuam tshuam rau hluav taws xob rwb thaiv tsev kev ua haujlwm ntawm cov pads thiab txawm ua rau cov pwm loj hlob. Lub hnub ncaj qha yuav ua rau cov roj hmab molecular thiab luv lub neej pabcuam, yog li cia yuav tsum zam kev tso chaw sab nraum zoov. Lub xaib ntim yuav tsum qhuav, cua, nrog haum kub, thiab deb ntawm cov tshuaj corrosive xws li cov roj stains. Kev khaws cia zoo tuaj yeem ncua sij hawm Pading kev laus thiab xyuas kom muaj kev pabcuam.
Yuav ua li cas xaiv nyob rau hauv - rail rau rau cov kab sib txawv?
High - Ceev Kev Railways muaj kev xaiv cov khoom siv roj hmab muaj zog thiab muaj zog kev co kom txo qis thiab khiav qhov tseeb. Nroog Rail Transit muaj tuab ib puag ncig puag ncig, yog li grooved synthetic roj hmab pads nrog cov txiaj ntsig kev txo qis yog nyiam. Cov chaw los nag yuav tsum xaiv cov ntxaij grooved nrog cov dej ntws zoo kom tiv thaiv cov dej tsis taus. Cov cheeb tsam nrog kev kub heev sib txawv tuaj yeem siv EPDM roj hmab pads tiv taus siab thiab qis kub kom haum rau kev hloov ib puag ncig. Qhov tseem ceeb ntawm kev xaiv yog kom muaj tseeb phim lub ncoo zoo nrog kab xwm txheej thiab ib puag ncig cov xwm txheej.
